The uniform nature of molecules in synthetic oil speaks it all. This is what keeps the lubricant more stable and makes it flow smoothly regardless of the temperature. But easy flow doesn’t mean the engine gets the freedom to consume the fluid the way it wants. In fact, such lubricants have special features to be consumed effectively.
So, does synthetic oil reduce oil consumption?
Yes, synthetic oils can reduce oil consumption thanks to seal swelling agents that prevent leakage and excessive oil consumption.
Let’s show you how that happens.
What's Inside:
Synthetic Oil And Oil Consumption
Synthetic lubricant is formulated differently. It contains pure base oil with uniform chemicals. There are fewer impurities in the fluid and it can resist the formation of deposits and sludge better than the conventional. Studies by AAA say the same. The result showed that synthetic oil can perform 47% better than its rival.
It has an agent made of sorbitol and carboxylic acid that works to swell the seals and keep them from leaking. No leaks mean reduced oil consumption. Plus, the oil’s uniform molecules ensure it stays thick at high temperatures and thin at lows to provide smooth and efficient flow without getting much consumed.
However, synthetic oils may not be suitable for older engines. The lubricant contains esters that refer to the blend of organic compounds and alcohol. Typically, this mixture can be severely rough on parts especially seals which can damage them and make them burn or leak more oil. In that case, conventional oil is better for old engines since it doesn’t have such risky ingredients.
Causes Of Engine Oil Consumption
Here are two major causes of high oil consumption in engines.
- Damaged Engine Parts
Parts of engine such as seals, pipelines, gaskets, and fittings can get cracked or damaged as the engine ages. This results in leakage that can cause oil consumption.
Damaged piston rings are another reason. When they wear out, the engine oil takes more time to enter the combustion chamber which leads to excess oil burning. Not just that, it also triggers carbon deposits to form on the rings.
- Unsuitable Engine Oil
Different engines need different kinds of engine oils. Getting the wrong one will cause more oil consumption. For instance, engines that require viscous oil can result in damage if low-viscosity fluid is used. As we all know, the lubricant gets thinner at higher temperatures. And diluted fluid creates more heat and friction.
Apart from improper picks, low-quality lubricant causes quicker oil consumption. Such engine oils don’t have the necessary additives that can keep the parts moving without damage.
Ways To Reduce Synthetic Oil Consumption
Experts suggest that the increase in fuel economy is what reduces motor oil consumption. However, picking the right oil matters too.
- Drive Slow
Speeding up your driving can increase the use of motor oil because of air and tire rolling resistance. So, make sure the acceleration is gentle. When it comes to light-duty cars, if you go over 50mph, you may need to pay around $0.20 more per gallon of gas for every 5mph. So, reducing the speed by 5-10mph can increase fuel economy by 10%.
Aside from following the speed limit, you should brake gently and gradually too.
- Decrease Vehicle Load
The extra weight of items inside will need more lubricant to push your car. For instance, if the item weighs 100 pounds, it can decrease the fuel economy by 1% more or less. Look for unnecessary stuff such as heavy baggage or wheels and unload them.
Plus, make sure to allow lesser riders to get inside so the car can move more freely.
- Using Proper Lubricant
The right pick will ensure smooth lubrication of engine parts while resisting any kind of leaks. For instance, high-mileage synthetic oil has different additives like seal swellers that help stop leakage. This results in less oil consumption.
Apart from selecting one for specific engines, make sure it’s of high quality to enjoy the same benefit.
Frequently Asked Questions
- What Is The Best Speed To Save Fuel?
The best speed to save fuel ranges from 55mph to 65mph. However, it depends on vehicle type. For passenger cars, the optimal speed would be between 40mph and 55mph while it would be slightly lower for trucks, SUVs, or other larger cars.
- Is Synthetic Oil Better For Engines That Burn Oil?
Synthetic oil is better for new engines since the contents don’t affect the parts as they would do to parts of older ones. However, if engine is the real culprit, then no matter which type you choose, it will consume the same amount of lubricant.
- Does High-Mileage Oil Stop Oil Consumption?
High-mileage oils can reduce oil consumption as they contain additives like seal conditioners and detergents. These contents make seals, gaskets, and O-rings swell as well as rejuvenate damaged covers. All of it helps lead to less consumption of lubricant and burn-off.
Final Words
Synthetic oils have lots of benefits to offer. They lose only 4% of their weight if run at 400°F for around 6 hours. It’s way less than conventional one that experiences 30% loss. Not just that, the contents of lubricants also work the keep the engines in shape by swelling the seals so that it could prevent leaks. All these show how synthetic oil reduces oil consumption.
