A temperature rise brings several changes in automotive lubricants. As long as it’s in the safe range, there’s nothing to worry about. But in case the fluid gets extremely heated, then it may result in internal and external damage.
The most common trait of a hot lubricant is that its viscosity becomes thinner. And another one is that the volume increases.
So, does engine oil expand when hot?
Yes, engine oil expands due to the increase in kinetic energy and distance between the molecules when heated. And as the temp goes up in the lubricant, different stuff happens. Let’s know more below.
What's Inside:
Thermal Expansion Of Engine Oil
Temp rise is common whenever it comes to the automotive engine. It can be due to weather or the machine itself. The friction of moving parts is one of the sources of heat. So, when we drive, the parts get hot, and so is the lubricant in the pan which flows to different areas through the filter to run smoothly. Here, the energy created by the movement of engine parts gets converted into thermal energy and increases the lubricant’s temp.
Now, what happens to engine oil when heated? Motor oil expands just like any liquid would at high temperatures. Since such a lubricant is liquid, the intermolecular interactions are fairly weaker. For that, the kinetic energy of those mobile molecules and the space between the atoms increase as the fluid is heated. This results in the expansion of engine oil. Meanwhile, the viscosity of oil decreases too.
Although the change in oil level is somewhat noticeable, we suggest that you avoid checking it immediately after stopping the vehicle. Otherwise, you may hurt yourself and your engine. Also, this won’t give you the correct measurement.
Volume Of Engine Oil Expansion At High Temperature
How much does oil expand when heated? Engine oil expands approximately 4.8% more volume per 120°F when hot. The calculation is based on the volumetric coefficient of expansion of unused motor oil i.e. 0.0004/°F. However, the size of expansion isn’t definite as it varies in the temperature, type, and condition of the lubricant. For instance, synthetic oil expands more than mineral ones when it’s hot.
If you want to know the expansion, you can check the change in engine oil level through a dipstick test. However, make sure to wait for around 10 minutes after stopping the vehicle so the lubricant gets back to normal temperature. This will help give you an accurate idea about the oil level in your vehicle.
Effects Of Engine Oil At High Temperature
Hot engine oil not only does expand but also creates unwanted situations. Here are what happens to your engine oil at high temps.
- The lubricant becomes diluted or less viscous.
- Severe friction creates noise and causes damage to moving parts.
- Quicker consumption of oil.
- Formation of sludge and sediments.
- Risk of leakage.
Frequently Asked Questions
- Does Engine Oil Shrink In Cold Weather?
Yes, engine oil would shrink in cold weather just like it can expand at high temps. The molecules of lubricant will get a little closer to each other causing the oil to shrink. Additives like viscosity improver contract during winter and make the fluid more viscous than it should be. As a result, the flow of engine oil gets slower while the pump puts the fluid under pressure forcing it to run through the filter.
- At What Temp Does Engine Oil Break Down?
Engine oil can break down at over 300°F. However, it depends on the lubricant type. Conventional motor oil can tolerate up to 250°F and start degrading as it goes past 275°F. Contrariwise, synthetics can withstand up to 450-700°F since they have higher level of tolerance.
However, you should try to keep the lubricant temperature between 240 and 270°F based on what you’re using.
- Does Synthetic Oil Burn Slower?
Yes, synthetic oil has additives that help it burn slower than conventional ones. It contains agents made of sorbitol and carboxylic acid that cause the seals to swell so that it prevents leakage and burns oil slowly.
Moreover, synthetic oil comes with uniform molecules that ensure the right level of viscosity at different temperatures to make the fluid flow smoothly without excessive burning.
Final Words
Severe expansion of engine oil is never good. Why? Because extreme hot oil can make things worse as we stated. So, you should try to keep the lubricant within 240-270°F.
How can you maintain the temperature of engine oil? Just following some simple tricks can keep the lubricant at recommended temp range. Avoid towing heavy stuff, driving aggressively, and extended idling. Use high-quality lubricant and change the oil or the filter as per the manufacturer. Also, check the level of oil regularly.

What Is Boron Used For In Motor Oil?
There are several chemical elements in lubricants, but there’s one of them that shines the most. And that is Boron. It gives life to the fuel so that our automotive engine continues to stay fit for a longer period.
So, what does boron do in engine oil?
Boron ensures higher lubricity of motor oil, reduction of friction, and lessening of engine noise while making the fluid more slippery so that the engine runs smoothly. It’s a metalloid used as a detergent, anti-wear, or extreme pressure additive in the lubricant.
The functions mentioned here are just the primary, it also has several unpopular benefits. Let’s explain how it works.
What's Inside:
Use Of Boron In Engine Oil
Boron is a metalloid element present in different formulations of lubricants. It’s mostly used in detergent additives. However, some of the antioxidants, extreme pressure agents, and anti-wear agents also contain the component.
It doesn’t stay as a whole in motor oil, rather comes in a compound. The common one is boric acid (BA) and hexagonal boron nitride (hBN).
BA tends to form a triclinic crystal structure where the atoms of Boron, Oxygen, and Hydrogen are closely packed with one another in each layer. This helps the layers slide easily with each other to give the engine system effective lubrication. Not only is it eco-friendly but non-toxic too.
Meanwhile, hBN features noticeable tribological properties and can even retain lubrication up to 4532°F. It too has a crystal structure where Boron and Nitrogen atoms are covalently bonded to each other as well as other atoms. All these layers allow for ease of sliding.
The strength of the film they form is the reason why boron is important in motor oil.
Percentage Of Boron Additive In Motor Oil
The amount of boron may vary from one lubricant product to other. However, the standard level should be 4% of boric acid and 4% of hexagonal boron nitride. Studies consider it the optimum concentration ratio of boron compounds.
However, since the level of boron decreases as the motor oil is consumed, we may need to add the additive to make up for the loss. It’s also suggested we use such additives after an oil replacement if the new one lacks such an element.
Benefits Of Boron In Motor Oil
Now the main question. Is boron good in engine oil?
Yes, boron is good for engine oil since it gives us several benefits. Even researchers found that the element has reduced fuel consumption and increased power efficiency. They concluded that such additives can decrease friction, especially at low temps, low speeds, and high loads. So, let’s take a look at the strengths of boron here.
- Friction reduction by making the film more slippery.
- Formation of tribofilm to provide anti-wear benefits.
- Noticeable thermal-oxidative stability.
- Prevention of sludge formation and corrosion.
- Lubrication of moving parts at high temperatures.
- Low consumption of fuel.
Where Is Boron Used In An Engine?
Boron can be used in any kind of automotive machine. You can consider it for engines such as-
- Diesel
- Petrol
- Liquefied Petroleum Gas
Frequently Asked Questions
- Which Boron Additive Should You Use?
Speedol F6 BOR can be an effective additive to consider for engine oil. In case your lubricant doesn’t have enough boron, it’d work to increase the performance of the fluid. Not only does it decrease friction and wear but also lessens consumption of oil, carbon dioxide emissions, and noise levels.
Moreover, it protects the moving parts against rust and corrosion while making sure the engine lasts and runs longer.
The product also lower engine oil temperature so that it works well with stability.
- Can Oil Additives Hurt My Engine?
No, additives like Boron compounds help increase the efficiency of motor oil. It ensures the lubricant does the job properly while keeping the engines in shape. However, the oil lacking additives can hurt your automotive engine. It’s because the fluid won’t be strong enough to give a shield between moving parts. As a result, the oil may become thinner and end up with increased friction and wear.
- What Are 4 Additives In Engine Oil?
Here are some of the additives commonly found in motor oil.
- Viscosity Index Improvers.
- Detergents.
- Antioxidants and Anti-wear agents.
- Corrosion Inhibitors.
Among these, boron is a common and efficient element present in detergents, anti-wear agents, and anti-oxidants. It keeps the engine well-lubricated while lessening friction.
Final Word
Lubricants contain several elements but boron seems to do most of the job. Starting from increasing the level of slipperiness and protection against heat to making the engine last longer, it gives different advantages.
Although most engine oils contain boron compounds, some may not have them. In such cases, you can buy boron additive products to mix with the oil. But before you do this, we’d suggest you talk to an expert regarding this or take the car to the service center.

Is Power Steering Fluid Corrosive?
Hydraulic fluid works to make the job of the steering wheel easier as it transfers power to the system. Not only does it fuel the system but keeps the moving parts lubricated too.
However, some fluids made for automotive parts have been accused of corrosion. Now, this can make you think about the power steering fluid too.
So, is power steering fluid corrosive?
Power steering fluid isn’t corrosive thanks to the presence of anticorrosion agents. Nevertheless, such inhibitors can break down over time due to heat and pressure which can make the fluid lose efficiency and cause corrosion.
What's Inside:
Power Steering Fluid- Corrosive Or Non-Corrosive?
Power steering fluid is typically hydraulic fluid composed of different additives like antioxidants, detergents, viscosity index improvers, and anticorrosion agents as well. The latter mostly comes in the form of amine inhibitors that help prevent or reduce the rate of corrosion. Some other elements such as alkenyl succinic, imides, and alkenyl succinic esters present in the fluid also work as anti-corrosive agents.
Moreover, the fluid contains phosphorus compounds and thiadiazole derivatives. These two can prevent corrosion of piston sealing of power cylinder, which eventually helps avoid fluid leakage. Hence, it benefits power steering with stable operation while making it last longer. So, the anticorrosion properties of power steering fluid make it non-corrosive.
However, the properties may not stay intact for good which can enable the fluid to cause corrosion.
Shelf Life Of Power Steering Fluid
Depending on different factors such as contamination, extreme heat, and pressure, the chemical compounds used in the hydraulic fluid can change and deteriorate. If unopened, the fluid can stay good for around 3 to 5 years. Meanwhile, opened fluid can last up to 2 or 3 years.
However, the frequency of use and several other factors can reduce the shelf life and degrade the fluid sooner than it should.
So, what happens to power steering fluid over time? As time goes by, the power steering fluid can oxidize which results in a change of color and buildup of residual varnish on the pump valves. When it deteriorates, the fluid loses properties that keep the seals and O-rings pliable. And as these parts harden, it ends up causing poor performance of the fluid and leaks.
In short, the ingredients in the fluid can break down over time which decreases its efficiency leading to the liquid becoming corrosive. Not just that, these after-effects are also what happens if you never change power steering fluid.
Frequently Asked Questions
- When Should Power Steering Fluid Be Changed?
We must flush power steering fluid after every 40,000 to 80,000 miles. However, it may vary since manufacturers can recommend the change sooner or later than the range.
That said, some warnings can let you know that it’s time for a replacement. Here are 6 signs you need to change power steering fluid.
- Heavy or difficult steering: Due to low or degraded power steering fluid.
- Color changes: From healthy light red to amber, gray, or black due to oxidation.
- Burnt smell: Due to damage of fluid as a result of overheating.
- Strange noises: Since the fluid deterioration will make the moving parts of the steering system cause abrasive friction. You may hear whining, scraping, squeaking, and scratching noises.
- Bubbles: In the hydraulic fluid of power steering.
- Leakage: Due to degradation of the fluid.
- How Do You Fix Power Steering Fluid Leak?
Fixing power steering fluid leaks depends on the causes behind them. If it’s the pressure valves or hose that’s broken, then you can buy and replace the parts yourself. In case the seal is broken, then you need to consider a full hose replacement. For that, it’s better to bring the car to the service center and let the experts do the job.
In any case, we suggest you take the experts’ help to fix serious fluid leaks since doing it yourself can be unsafe for you and the car. Typically, the leak may cost around $500 to 700$ to repair depending on the parts that failed.
- What Happens If I Spill Power Steering Fluid?
It’s not a problem if there’s a little spill of power steering fluid on the engine and transmission. It will just get oily and dirt and won’t cause any harm. You can fix it by wiping the parts with a degreaser.
If the fluid gets on the exhaust pipe, manifold, or catalytic converter, it may cause smoke. However, the smoke shouldn’t cause the exhaust components to burst into flames. But we suggest you contact an expert in case of such smoke to be safe as it can cause a fire too.
Final Words
Power steering fluid has anti-corrosion properties that help it prevent corrosion as long as it’s functional. Nevertheless, extreme heat, pressure, and contaminants can affect the agents and make them prone to corrosion.
Hence, you should flush the fluid according to the manufacturer’s recommendation. Also, look for signs of degradation in case the fluid goes bad sooner.

Does Engine Oil Brand Matter?
Whenever we think of purchasing lubricant for our vehicle, we always prioritize quality. After that’s met, comes the compatibility and other factors. Most of the time, we’d like to look for options among popular manufacturers.
But does engine oil brand make a difference?
Yes, engine oil brands can make a difference since such lubricants are made of high-quality additives with improved formulations. Off-brands mostly use ingredients and fillers that can harm your engine. So, engine oil brand matters.
However, there’s still a “BUT”.
What's Inside:
Brand Name Motor Oil Vs. Generic
Motor oil comprises common ingredients including petroleum hydrocarbon base stock and different additives. However, having similar contents doesn’t mean the lubricant will be identical. Even a small change can change its properties. This may make the fluid different from others but what about the quality?
Are all engine oil brands the same quality? No, brands manufacture engine oil their way which makes the quality different. It mostly depends on factors like process of production; kinds and grades of contents used in the lubricant; and blends of contents.
However, while branded oils have some fans, generic ones attract people with tight budgets.
Branded Motor Oil
They are most likely to have a high level and class of additives. This helps prevent oxidation, reduce sludge formation, and keep the engine well-lubricated.
Plus, their lubricant is supposed to be licensed by API (American Petroleum Institute). This is like a certificate to show that the oil has been thoroughly tested and meets the API standards to ensure quality.
Not just that, the lubricants of popular manufacturers also draw attention of experts. Hence they are heavily researched to give us more insights about them. For instance, this study on Pennzoil.
Although their steeper price is a con, the lubricants can still fail to perform effectively.
Generic Engine Oil
They may meet minimum API specifications. However, they mostly use inexpensive ingredients that make them achieve lower price points. Some can also be recycled which would just last up to 3,000 miles.
Because of being generic, it’s tough to do investigations on each lubricant. Hence, we get skeptical about their reliability. However, some lubricants can still work better than those of popular brands. So, if the oil weight, viscosity, type, and certification match what your vehicle requires, then it’s safe to get one even if it’s non-branded.
Top 3 Brands Of Engine Oil
- Pennzoil Motor Oil
Pennzoil was started by Michael Late Benedum and Joe Trees but now is owned by Shell plc. Their lubricants comply with the specs of API SN PLUS category. Not only are they formulated to resist severe conditions but also made of natural gas that keeps the engine clean.
- Valvoline Motor Oil
It’s a company by Ashland Incorporation. Most of their lubricants can efficiently decrease friction and sludge buildup. Plus, they claim to perform all five tests for both API and ILSAC petrol categories in their engine test laboratory.
- Castrol Motor Oil
This British company was started by Charles Wakefield. Their motor oil formulation is claimed to meet the required standards under the API SN PLUS specifications. They say their oil can work well in different situations that put severe stress on the engine.
Is It Bad To Change Oil Brands?
No, as long as the grade/viscosity of lubricant is the same or better and it matches the specs/ API ratings the company recommended, switching motor oil brands wouldn’t be bad.
However, a change in grade can affect performance to some extent. Lower quality and incompatible viscosity will cause damage to the engine. Meanwhile, using the right type of lubricant or upgrading to one with better formulations will benefit the engine in long term.
Frequently Asked Questions
- Which Brand Of Oil Is The Best For Engine?
Pennzoil brand offers oils that can suit the engine well. Their synthetic lubricants are made from natural gas and are 99.5% free of impurities.
As for the product, the Platinum engine oil can be a good option to consider. It gives protection against friction and extreme heat while ensuring smooth oil flow regardless of different temperatures.
- Can You Mix Engine Oil Brands?
Yes, you can blend engine oil brands as long as the grade and viscosity are similar or better and the API rating matches. For instance, you can mix Pennzoil with Quaker State if the instructions are properly followed. It wouldn’t cause damage to the engine. However, mixing lubricants of different grading will surely be risky for your vehicle.
- Which Motor Oil Brands Should You Avoid?
Here are 3 of the motor oil brands that you should avoid since they don’t meet API or ILSAC standards.
- Xpress Lube Pro: Low-quality additives.
- Mileage 365 Motor Oil: Contain abrasive materials.
- Questron Motor Oil: Don’t come with viscosity grading and are highly volatile.
Final Words
Even if brands are popular, do check whether their lubricants meet all the standards. Plus, they should use additives of quality since that determines overall performance. However, if you find a generic motor oil that has everything your engine needs, you can surely go for it.
Make sure you don’t use products that can do all. Because some are also made to work with lawnmowers, chainsaws, and weed eaters apart from vehicles. These lubricants typically lack the kind of ingredients required by the motor.

Does Motor Oil Degrade Over Time?
Lubricants dedicate themselves to engine parts so that they run effortlessly. Every component added to the oil makes sure it serves the vehicle well without affecting itself. But no matter what, the quality won’t stay top-notch for always. It can be affected whether the oil has been used, unused, opened, or unopened. Now, this can raise a certain question-
What's Inside:
Does engine oil break down over time?
Yes, engine oil degrades over time due to different circumstances like overheating or extreme temperature, oxidation, moisture, and contaminants. Its shelf life increases or decreases based on the type of lubricant, use, maintenance, condition of the engine, and other stuff.
Let’s know how and why it happens.
Causes Of Motor Oil Deterioration
Just like any other thing, lubricants have a shelf life too. Their expiry date depends on several situations so there isn’t any specific answer to it. Now, what causes motor oil to degrade?
Temperature, air/oxygen, and moisture are the roots of degradation. All of these cause contamination, thermal breakdown of oil, and oxidation that lower the quality of engine oil.
Contamination Of Motor Oil
Metal wear products and soot are some contaminants that affect the physical and chemical properties of engine oil. It thickens the lubricant to a great extent and causes pumpability issues.
Thermal Breakdown Of Motor Oil
Engine oil has a specific heat capacity thanks to the metal additives that are used as anti-wear agents. This helps the lubricant absorb heat and makes the parts move smoothly.
However, sometimes, the fluid can get hotter than the recommended temperature. In that case, the thermal conductivity of the engine oil helps it transfer heat to the oil pans so the heat can be dissipated.
If the lubricant’s thermal conductivity is low, then it can lead to overheating. And this can make motor oil vaporize or decompose. As a result, essential additives will be removed from the engine degrading the quality of the lubricant.
Oxidation Of Motor Oil
Environmental elements like air and water have oxygen that reacts with oil, causing oxidation and a chemical change. While degrading lubricant, this ends in base oil breakdown, additive depletion, sludge and sediment formation, acid number increase, filter plugging, and oil thickening.
Shelf-Life Of Motor Oil
How long does engine oil take to degrade? Depending on different factors such as lubricant type, engine condition, temperature, environmental elements, and driving speed, lubricants can last up to 5 years. That’s how long motor oil lasts. However, we are talking about conventional engine oil here. If it’s synthetic oil, it can last about 6 months to 1 year.
Studies have shown that the oil properties change significantly at over 18,000 miles. But that can still vary based on several factors.
So, it’s safe to replace the lubricant once the car hits 5,000 to 10,000 miles. Some vehicles can go more than that smoothly with the lubricant intact. But it’s better to check the guidelines or ask the expert.
5 Signs Of Degraded Motor Oil
Lubricant will surely let you know when it starts to deteriorate. So, how can you tell if motor oil has gone bad? We got 5 signs that act as oil deterioration warnings.
- Burnt odor due to a mix of sludge and carbon
- Dirty and black color.
- Changed viscosity.
- Engine vibration and noise due to friction.
- Slow acceleration of the vehicle.
Frequently Asked Questions
- Does Motor Oil Degrade If Not Used?
Yes, motor oil can degrade by just sitting inside the engine. It has a shelf life ranging from 6 months to 5 years. When unopened, it stays good in the bottle until its date of expiration. As it goes past time, different factors such as changes in chemical composition can lower the quality of lubricant. Hence, it won’t work effectively.
In case the oil has been opened and still not used, it can stay good for 5 years. However, exposure to environmental elements can degrade the engine lubricant.
- What Happens If You Don’t Change Your Oil For 2 Years?
When you don’t change motor oil for 2 years, it starts to solidify or gel in the engine and becomes sludge. Such affected oil can’t get into all the engine parts which leads to oil starvation in the valve train components, camshafts, bearings, and crankshafts.
So, you must replace the lubricant at least once every 2 years.
- How To Prevent Motor Oil Oxidation?
You need to follow some simple steps to prevent motor oil oxidation. Just make sure the bearing seals are in good shape. The pressure of reservoir system shouldn’t be exceeded. Plus, consider using gas with low reactivity since it can help prevent air from getting inside. Nitrogen can be a good option.
Final Words
While the quality of motor oil can change based on various circumstances, you can make it last a good time by following some simple steps. Just make sure the lubricant isn’t exposed to extreme temperatures since it can cause dilution. Plus, keep the oil away from heavy air otherwise it may lead to condensation buildup.
For the maintenance routine of your vehicle to a T. Use the recommended parts, lubricants, and fluids. That’s how you can stop motor oil from deteriorating quickly.

Does Engine Oil Absorb Heat?
Lubricants have been praised for ages because of their ability to handle automobile engines. Whenever metal parts are on duty, the fluid clings to them and makes them maneuver smoothly against each other. But that’s not only it. The fluid has different elements that protect your engine in different ways. It can deal with the temperature even if it goes up.
So, does engine oil absorb heat? Yes, engine oil absorbs heat thanks to the anti-wear agents. Aside from holding heat, it transports the energy to the oil trays where the heat dissipates while preventing the system from overheating.
Here we’ll be discussing how oil keeps engine cool.
What's Inside:
Absorption Of Heat By Engine Oil
Auto engines comprise several moving parts. When they rub against one another, the friction generates heat. This heat is taken in by motor oil and transferred to locations like the sump, pump, filter, and oil lines to be safely dissipated into air. Some oil systems have cooling fins that maximize the cooling action and reduce the heat load.
But how engine oil holds heat? Engine oil contains some metal additives that work as friction-reducing or anti-wear media. They have individual heat capacities depending on different factors like temperature and the quantity of additives. Studies say that this function helps the oil improve its ability to retain heat and form a protective film between metal parts.
If motor oil didn’t have this element, the internal parts would overheat and fail to run smoothly. Hence, aside from lubrication, the oil works to cool different parts like valves, heads, and piston assembly.
Thermal Properties Of Engine Oil
Motor oils can hold heat to a great extent in case they are viscous enough. Even if it crosses the threshold, they’ll just transfer heat without degrading themselves.
The specific heat capacity of engine oil ranges from 2.306 to 3.063 J/g/K. whereas the thermal conductivity of engine oil ranges from 0.116 to 0.145 W/(m/K). The more the values, the more effectively fluids can deal with heat and minimize friction loss.
What Are The Benefits Of Engine Oil?
Engine oil not only does lubricate the metal parts but also works as a cooling and cleaning agent. Here are 5 benefits that we can get from the oil.
- Lubrication
- Cooling
- Cleaning
- Protection against corrosion
- Sealing
Frequently Asked Questions
- Does Synthetic Oil Reduce Heat?
Yes, synthetic oil reduces heat but not directly. It actually decreases the friction that creates heat and helps the parts move smoothly.
These oils contain additives such as anti-wear agents, antioxidants, corrosion inhibitors, dispersants, cleansers, and other elements that increase the oil’s ability to resist extreme pressure and heat while preventing waste buildup. Such ingredients and functions are the prime advantages of using synthetic motor oil. It handles extremely high temperatures as well as low temperatures.
- Which Engine Oil Is Best For Heat?
Synthetic engine oil has uniform molecules and additives that make them handle heat better than conventional ones. Not only does it lubricate the parts and keep the engine clean but also manages to not break down fast. Moreover, the components help the oil stay thick so that it sticks to the engine parts, makes them move smoothly, and produces less waste.
When it comes to products, we recommend Mobil 1 10W-40 as it can protect the engine from heat of up to 500°F. Coming in 5 quarts, it can be suitable for engines with 75,000 miles or above. Plus, it can go over 10,000 miles before you need to change the oil.
- What Happens To Engine Oil When Heated?
Engine oil starts to break down and get thinner as it’s heated. The oil drains pretty quickly while keeping the parts less lubricated. However, it all depends on the temperature.
Extreme heat can also decrease the additives of oil sooner which makes the fluid less efficient. This leads to more sludge formation which can clog narrow passages of oil and block the oil from getting into essential components. As a result, it can cause damage to the parts.
Hence, we should pick engine oil that has the right amount of viscosity and additives so it can stay thick at high temperatures.
Final Words
Engine oil has lots of good stuff to give to improve the life of your vehicle. However, we just have to ensure getting the right kind of product keeping the temperature, car’s condition, mileage, and driving pace in mind.
For hot weather, we should opt for high SAE-rated oil to deal with high temperatures. It should have better viscosity and a higher value of specific heat to make the parts run effortlessly without getting affected due to heat be it of the weather or friction. That’s how well engine oil can hold heat.
