Understanding the Longevity of Synthetic Oil

In the world of engine maintenance, synthetic oil dazzles with its unique abilities. But how long can this automotive elixir continue to perform its magic? Let’s embark on a journey by understanding the longevity of synthetic oil.

Synthetic oil is specially made in a lab to last longer than regular oils because it’s free from things that make oils age quickly. But remember, it’s not invincible! You need to take care of it to make sure it lasts.

Think of temperature, and where you store it as the protectors of synthetic oil. Just like we feel better in comfy places.

Synthetic oil works best when it’s not too hot or too cold. It’s afraid of water, so keep it dry because even a little drop can make it age faster.

To make sure your synthetic oil lasts, follow what manufacturers say and take good care of it. Check how it looks regularly, and if it still looks good, it’ll work well.

In our journey to know how long synthetic oil lasts, we found its secrets and realised we’re its protectors. Taking care of it means our engines stay smooth for miles.

Factors Affecting Synthetic Oil Shelf Life

Several factors can influence the durability of synthetic oil shelf life. If you knew these factors, you could maintain the oil’s quality for a long time. Let’s talk about them.

Storage Temperature: Extreme temperatures, both hot and cold, can negatively impact synthetic oil. So keep it in a cool, stable environment to preserve its quality.

Exposure to Light: The sunlight and UV radiation speeds up oil’s degradation gradually. So you have to keep it away from direct sunlight.

Air Exposure: Exposure to air, this can cause the oil to become thicker and less effective. So you must seal the container tightly after every usage.

Moisture and Humidity: You must keep your synthetic oil away from moisture as it is a certain enemy of synthetic oil. It can lead to oxidation and oil breakdown.

Contaminants: Contaminants like dust, dirt, and debris can compromise the quality of synthetic oil.

Oil Additives: To keep the synthetic oil on your shelf, it’s better to follow the manufacturer’s recommendations. Because some synthetic oil contains different additives.

Use of Partial Containers: If there is still oil in your container, keep it into a small bottle. Otherwise, synthetic oil may lose its quality because of extra oxygen.

These are the points you have to follow up if you want to expand your synthetic oil shelf life.

Signs of Synthetic Oil Degradation

After a certain time, 6-12 months, it is better to change the synthetic oil of your car engine. But what if the oil lost its efficiency before the expected time? 

You should not run the engine anymore.

Here are most  7 signs, once any of these happen to your car engine, replace the engine fluid asap — synthetic oil.

1. Colour Change: It looks amber when it is fresh and new. After using it for a certain time, it becomes dark from clear or amber to brown or black.
2. Reduced Fuel Efficiency: If engine oil loses its efficiency, it creates an impact on fuel too. So when your car engine consumes more fuel and oil than usual, it’s another sign of synthetic oil degradation.
3. Unpleasant odours: Because of overheating, it creates a strange smell — something is burning. So it’s time to change to synthetic oil.
4. Increased Engine Noise: When the oil loses its lubricating ability, the engine creates more sound/noise.
5. Decreased Oil Thickness: Synthetic oil becomes thinner over time because it gets worn out from use and hot temperatures. When it gets thinner, it can’t protect the engine parts as well, resulting in changing the oil being essential.
6. Check Engine Light: When the check engine light is on, it’s a sign of something inconvenient with your engine too. So check the synthetic oil if it has a reason.
7. Sudden disruption: if the car engine suddenly turns off when driving, it’s also another sign of synthetic oil degradation.

So, aforementioned signs are the main signs of synthetic oil degradation. If you want to keep your car engine healthy, notice the signs and take action accordingly.

Understanding Diesel Engine Lubrication

Diesel engine lubrication is a vital aspect of a car that should be understood thoroughly. It also directly impacts the engine’s efficiency and lifespan.

Diesel lubrication is about using good-quality oil to reduce friction, prevent wear, manage heat, and keep the engine working well.

Here is How to Understand Diesel Engine Lubrication

1. Lubrication’s Role:

• Diesel engine lubrication ensures the engine’s moving parts operate smoothly without excessive friction or heat generation.
• It prevents metal-to-metal contact between components in the engine, which can lead to premature wear and engine damage.

2. Types of Lubrication:

• Diesel engines typically use either wet-sump (oil stored inside) or dry-sump (external oil reservoir) lubrication systems.

3. Oil Circulation:

• The lubricating oil is pumped from the oil pan or reservoir to critical engine components, including the crankshaft, camshaft, pistons, and bearings.
• The oil forms a protective layer, reducing friction and dissipating heat.

4. Viscosity Matters:

• The viscosity of the engine oil is crucial. It determines the oil’s thickness and ability to flow under different temperatures.

5. Filter and Cleaning: 

• Oil filters are used to remove contaminants and impurities from the oil, ensuring it remains clean and effective.
• Regular oil changes are necessary to maintain the quality of lubricating oil.

6. Cooling Function:

• In some diesel engines, the engine oil also helps with cooling by absorbing heat from the engine components and transferring it to the oil cooler.

7. Maintenance:

• Regular checks, oil changes, and filter replacements are effective lubrication.
• Engine manufacturers provide guidelines for maintenance intervals and oil specifications.

8. Synthetic Oil:

• Synthetic oil is a popular choice for better protection, efficiency, and longer change intervals.

Understanding diesel engine lubrication means knowing how vital it is for the engine, doing proper maintenance, and picking the right oil (like synthetic) for the engine to work well, last long, and perform efficiently.

Benefits of Synthetic Oil for Diesel Engine

Synthetic oil offers several benefits that are essential for diesel engines. Among them the most significant advantages is improving engine protection.

The benefits are…

• Enhanced Lubrication.
• High-Temperature Performance.
• Improved Fuel Efficiency.
• Extended Oil Change Intervals.
• Optimal Cold-Start Protection.
• Resistance to Sludge and Deposits.

Synthetic oil has a higher viscosity index, which means it maintains its viscosity under extreme temperatures and pressure, providing better lubrication for engine components.

Furthermore, its superior lubricating properties reduce friction, which can lead to improved fuel efficiency and reduced emissions with oil consumption.

Synthetic oil is also less prone to oxidation, ensuring longer intervals between oil changes, reducing maintenance costs and increasing convenience.

This makes synthetic oil ideal for use in heavy-duty diesel engines that require robust oil performance.

They say having just 5 quarts will be enough for most of the vehicles. But this is a general statement. Instead, ask the manufacturer or check the car manuals to see the volume of lubricants the engine needs. Yes, we can say, it falls in the medium range.

But, is 5 quarts of oil enough? Yes, and No! Five quarts of oil is enough for small engines and short trips but not for bigger ones and longer drives. However, it depends on the engine condition, cylinder size, use frequency (rpm), oil type, driving habits, and many factors.

That said, there are lots of things to consider before we conclude. Let’s talk about them.

Driving With 5 Quarts Of Oil

Some might say it’s safe to drive with 5 quarts of oil to a certain extent while some warn about it. This can make one wonder!

How long can you drive with 5 quarts of oil?

5 quarts of oil can give you a range of 3000 to 6000 miles. The idea comes from manufacturers that consider a quart is burnt in every 600 to 1200 miles approximately. You can enjoy more miles with 5 quarts of synthetic oil.

Speaking of which, the type of lubricant should be considered too. Conventional oil breaks down and burns faster than synthetic as per the studies. How? Synthetic fluid has uniform molecules that handle higher temperatures better without getting much consumed. Hence, the oil doesn’t degrade fast. This is something conventional oil lacks. That’s why, choose synthetic oil over conventional.

However, sometimes, the lubricant might get consumed more quickly. In that case, going more miles will put your engine at risk of damage while sending you a low oil level warning. So, make sure to follow the manual instructions and suggestions accordingly.

Engine Oil Capacity All Cars

Typically, cylinders may need 5 to 8 quarts of oil. That said, the size of an automotive engine can tell you how much oil is needed.

A rule of thumb is that the smaller the capacity of cylinders, the less lubricant is required to fill them. Contrariwise, the bigger the size, the more room there is for fuel. Typically, vehicles come with 3, 4, 6, or 8 cylinders. Here’s a small detail on how much oil your car needs by the engine size.

1. Three-cylinder engine holds 2 to 3 quarts of oil.
2. Four-cylinder engine holds 3.5 to 5 quarts of oil.
3. Six-cylinder engine holds 5 to 6 quarts of oil.
4. Eight-cylinder engine holds 6 to 8 quarts of oil.

However, some may have more or fewer cylinders.

Most passenger cars have a 4-cylinder engine and they can easily be filled with around 3.5 to 5 quarts of lubricant.

Some have 6 cylinders that should hold at least 6 quarts. However, they can take around 5 quarts quantity and won’t hurt as long as it’s just a quart low to reach the maximum level and the lubricant consumption is slow. In case your engine burns oil fast, it’s better to keep the tank full.

As for the 8-cylinder engine, you can add 5 quarts but note that you can’t go far with low oil. If you try to drive more miles, the oil will be consumed faster and lead to more friction between the parts and damage to the engines. So, we would recommend filling the reservoir with enough lubricants.

Frequently Asked Questions

1. What Happens If My Oil Is Below Minimum?

Oil below the minimum line can lead to wear and tear in the engine system. So, don’t drive with low oil level. It can cause oil burning and excessive smoke out of the exhaust. Plus, friction can increase which can generate more heat. Because of severe rubbing between the parts, it consumes more oil to function well. Low oil can also cause rust and corrosion. All these will result in causing damage to the engine

Hence, make sure you have the cylinder refilled at the right time before any accident happens. Also, take the vehicle to the service center if you suspect any damage.

2. How Often Should You Top Up Engine Oil?

Engine oil level should be checked at least twice a month, and make sure to top up accordingly.

In case of an oil change, the majority of the vehicles come with fixed interval servicing. It means the oil should be changed every 3,000 to 9000 miles or every 3 to 12 months depending on the engine size and other conditions.

Final Words

Using sufficient lubricant is always recommended since it’ll keep you and the vehicle safe. Going a quart low is still harmless if you maintain the rules properly. By rules we mean, running the vehicle at a limited range of miles and replacing the lubricant on time.

So, is it ok to drive with 5 quarts of oil? Yes, it’s fine to drive with 5 quarts of oil as long as you keep the trip short and change the oil when it goes near the low level.

Related Post: Does Synthetic Oil Reduce Oil Consumption?

Related Post: Can You Mix Synthetic Oil with Regular Oil?

The only way to cool down an engine would be to bring it the right lubricant and maintain it properly. Here, viscosity plays a significant role and you’ll find some say, engines run smoothly when the fluid is efficiently viscous. Does it mean; that’s better?

Does thicker oil keep the engine cooler? Thicker oil can help keep the engine cooler indirectly as it can absorb heat and carry it away.

However, it depends on different factors and can cause the opposite situation. Here, you will find out how the viscosity of oil makes a difference to the engine conditions.

Role Of Oil In Keeping Engine Cool

Lubricants contain additive metals that act as anti-wear and friction-reducing agents. They have their own heat capacities that help the oil retain heat and form a strong film between engine parts. Not just that, they also have a thermal conductivity that makes them transfer heat to oil trays, so it dissipates into the air.

In short, it keeps the engine lubricated, reduces friction, and removes heat. That’s how the oil makes the engine stay cool.

However, lubricants with incorrect viscosity can create troubles.

1. Too thick oil at high temp: may force the engine to work harder and cause increased drag.
2. Too thick at low temp: can cause poor flow and starting issues.
3. Too thin oil at high temp: can cause excess friction and engine damage.
4. Too thin at low temp: can fail to provide sufficient lubrication and lead to damage.

Choosing The Right Oil Thickness To Run Cool

Studies say that lubricant viscosity is highly temperature dependent. It increases as the temp goes down and decreases as the temp goes up. So, just going with a thicker oil randomly won’t help. Because we need to consider the type of engine, the severity of friction, and how hot or cold it is.

Lubricants should be thick for higher heat to function properly. Because it won’t be affected by the extreme temp. Instead, it will keep the parts well-lubricated while removing heat from them. Now, which engine oil is best for high temperatures? Depending on the manufacturer’s recommendations, oils with 5W30 to 10W40 can be suitable for scorching summer. The higher the rating, the thicker, hence, the better.

In colder weather, engines don’t produce extra heat so it’s okay if the lubricant is somewhat thin. The outdoor temp can thicken the oil anyway to some extent. However, a high-quality oil will ensure stability and smooth flow across the system no matter how low the temp is. In that case, which oil is better for colder temperatures? 5W can be better for winter use since it moves smoothly while making sure the engine doesn’t get hot. Plus, it provides easier starts.

Notes: Do check the viscosity rating and grade suggested by the OEM (original equipment manufacturer) to get the right one. A multi-grade synthetic lubricant can be efficient since it handles and resists extreme temps well. Such oils also contain viscosity index improver that ensures they don’t get too thick or thin.

Frequently Asked Questions

1. What Happens If Engine Oil Is Too Thick?

Your vehicle may experience starting troubles and improper lubrication if engine oil is too thick or viscous. But this is mostly applicable for low temps. Then again, some clear and hidden signs will help you here. Let’s give you some more ideas regarding what else can happen.

Engine Oil Too Thick Symptoms

1. Takes a longer time to pump.
2. Pressurize the bearings.
3. Starting difficulty.
4. Forcing engine parts to work harder.
5. Higher stress on engine parts, hence shorter engine life.
6. Poor fuel economy

Engine can experience damage even if you use lubricants thicker than what’s recommended at high temps. So, we suggest following what manufacturers or experts say.

2. How To Keep Engine From Overheating?

Having a coolant and ensuring its efficiency can keep the engine from overheating. Because this is the main purpose of such a system. In case it runs out of antifreeze fluid, just top it off to keep it going. Here are some more techniques you can follow to reduce overheating.

• Turn on the heater and switch it to full blast while keeping the windows open.
• Turn off the air conditioner and reduce engine strain. 
• Check the coolant and temperature gauge regularly. 

In case you find any issues and notice that the temp isn’t going down, take it to the experts.

3. Do Engines Run Cooler With Synthetic Oil?

Yes, synthetic oils have additives with thermal conductivity that ensures absorption and transfer of heat to other locations while keeping parts lubricated. This way, such lubricants help keep the engine cool.

Not just that, researchers found that synthetic oil handles temperature better thanks to the uniform molecules composition. It flows across several parts and doesn’t get quickly consumed.

Final Words

Viscosity of engine oil is significant. But as you can see, going beyond the recommended range can cause trouble too.

So, you shouldn’t ask whether thicker oil runs cooler. Instead, ask what viscosity of oil to use for your engine to stay stable. You’ll get the answer right in the manuals of equipment manufacturers. We suggest using the oil according to the temperature and engine type.

The formulation of transmission fluids keeps changing and updating with the advancement of vehicles and their mechanisms. Although ATF+4 managed to keep pace with the upgrade, Dexron 3 stopped in the mid (with H) allowing different versions (like Dexron HP or ULV) to continue. But that’s not what makes them different. There’s one vital point. 

So, what is the difference between Dexron 3 and ATF+4? Dexron 3 is a conventional auto fluid made for older transmissions of Chevy and Ford while ATF+4 is synthetic and compatible with older and modern models of Chrysler, Ram, Jeep, and Dodge. 

But wait, there are more dissimilarities that we found out. 

Dexron 3 Vs. ATF+4 

Both are made for specific mechanisms that make one different from the other. However, DEX 3 kind of has outdated ingredients whereas ATF 4 comes with an updated formula. 

Below, you can read more about ATF 4 vs Dexron III.

Dexron 3

Dexron comes with a series of ATFs that are compatible with transmissions of Chevrolet and General Motors. Although the original one (DEX B) was introduced in 1967, the first version of DEX 3 (F) appeared in 1993 while the last version, DEX 3 (H) in 2003. 

When it comes to Dexron 3, it’s a standard conventional fluid made of Group 2 base oil and special additives. It acts as a hydraulic fluid and lubricant for different mechanisms like transmissions, manual gearboxes, transfer cases, and power steering systems. 

You can use it in older Chevy models like GM transmissions pre-2005, Ford transmissions introduced between 1983 and 1996, and the ones that require DEX 2. However, the newer the automotive models, the later the fluid versions that are required. 

For instance, Electric Vehicle (EV), Hybrid (HEV), Newer 6, 8, 9, and 10-speed transmissions would need particular fluids to work properly. So to make the fluid compatible with modern transmissions, its specifications have been upgraded over the years. 

ATF+4

ATF+4 is created to meet the requirements of Fiat Chrysler auto transmissions (FCA). It can be used in transmissions of Ram, Jeep, and Dodge models too. The fluid was released in 1998 by Chrysler and was stated to be officially licensed. 

It’s fully synthetic and contains Group 3 base oil with a variety of additive packages. ATF+4 acts as both hydraulic fluid and lubricant for the transmission system, hydrodynamic converters, and steering systems. However, the formulations have changed over the years. 

While the original version was suitable for Chrysler mini-van transmissions, the revised ones were compatible with the latest 6-speed transmissions. ATF+4 also has specific additives included for particular transmissions. 

It might work for the mechanisms that require ATF+, ATF+2, and ATF+3 fluids. You can also use it in most of the older and some of the newer models of the stated manufacturers. All you need is to check their compatibility.

Frequently Asked Questions

1. Can You Mix Dexron 3 With ATF+4?

Yes, you can mix Dexron 3 with ATF+4 as long as they meet the specifications of the transmissions. Since one is conventional and the other is synthetic, you’ll end up with a synthetic blend. It’s a safe mixture if you’re using the vehicle at a medium level. 

In case the system is operated in severe conditions, the blend will fail to function properly. Hence, we wouldn’t suggest mixing the types as it won’t maintain the quality. Not just that, the worst thing that can happen is the slip of torque converter clutch and transmission wear. 

2. Can I Use Dexron Instead Of ATF+4?

No, using Dexron instead of ATF+4 can degrade your transmission system. Most of the Dexron fluids are outdated whereas ATF+4 comes with upgrade formulas. 

The system that’s compatible with ATF+4 would need certain alternatives. For instance, AMSOIL Multi-Vehicle ATF can be a suitable option since the quality and grade are similar. 

Meanwhile, Dexron fluids are for older engines and you can use them with the ones that call for them. 

3. Is Dexron 3 The Same As ATF+4?

No, Dexron 3 and ATF+4 have different formations made of different contents. They are also designed for particular transmissions of certain brands. The only similarity is that they are transmission fluid that also acts as a lubricant. 

Final Words

The key difference between Dexron 3 and ATF+4 is the use of contents and additives in them. Also the vehicles they are formulated to be used in play a vital role. 

Although you can use ATF+4 instead of Dexron fluids, the opposite is a big no. It’s because ATF+4 is a high-quality fluid and can give you advanced benefits. Meanwhile, Dexron 3 is just for older models of Chevy or Ford and works to perform average. 

However, we suggest you always check the specifications of vehicles and transmissions and get the fluid accordingly.
