For effective protection and lubrication of the engine components, oil is necessary. A quart of oil burning for 1000–1500 miles is considered normal, but anything exceeding that means the engine uses more oil than is necessary.
This can be caused by oil in the engine’s engine combustion chamber, old engines, careless driving, or oil burning. Blue smoke and a burning oil smell can be caused by increased oil consumption.
Let’s go over it in more detail.
What is the reason a car consumes too much oil?
High lubricant consumption in cars is mainly due to oil burning or leaking from the engine. Here are some reasons for excessive oil consumption in vehicles.
1. Old engine
An older engine uses more oil that a new one. This can be caused by worn parts of the engine, which could lead to oil leakage or oil fire. New engines use less oil than engines that have traveled over 120,000 miles.
2. Head Gasket Damaged
Gaskets seal the combustion chamber. Overheating can damage the head gasket or cause gaps. The oil can burn in the combustion chamber, or seep out of the engine. You can replace the head gasket.
3. High-performance vehicles
High-performance vehicles have a faster oil burning rate. This is because high-performance cars have higher rpms and speeds, which means that the pressure on seals increases, leading to an increase in oil consumption. Oil consumption will increase if you drive at high speeds or in rough driving conditions.
4. Piston rings worn out
Piston rings transfer heat between the heated pistons and the cold cylinder wall. Friction causes the piston rings to wear. This caused the seal between piston and cylinder wall to fail. This allows engine oil to leak into the combustion chamber and cause it to burn. If the valve guides fail, engine oil can also enter the combustion chamber.
5. The wrong engine oil
It is important that the engine oil used should be well-matched. Engine oil of the wrong type or viscosity will cause problems with lubrication and increase oil consumption. To ensure the correct oil type, check the owner’s guide or consult a mechanic.
6. Damaged oil cap/filter
Dirt can get into the engine oil through blocked oil filters and damaged oil caps. This can reduce oil flow. This can lead to more engine oil being consumed. Oil can leak from the engine if there is a damaged oil cap. Oil leakage could also occur if the oil filter is damaged or clogged.
How can I reduce the consumption of my car’s engine oil?
These are some tips to reduce oil consumption in your car:
1. Change the engine oil
Every 7.500 to 10,000 miles, you should change your engine oil. The engine oil will no longer be able to adequately lubricate engine parts and this can lead to increased oil consumption.
2. Make sure to use the right viscosity oil
You should switch to a more viscosity oil if your car is using more than 1 quart per 1500 miles. Using 10w-30 oil may cause less oil to burn in your engine compared to 10w-30. Higher viscosity oil burns more easily at high temperatures.
3. Repairing oil leakage
Repair oil leakages in the engine. Oil can leak from valve covers that are damaged or loose. Use a torque wrench to tighten bolts properly in this case. Check the gaskets, and check the piston rings. It is possible to replace damaged gaskets and piston rings.
Other tips to help you avoid oil consumption
- Keep your engine oil clean and continue to drive safely in order for it to last longer.
- Replace the oil filter and ensure that there is no dirt or debris in the oil.
- The tank should be flushed with oil and the compartment cleaned.
- Synthetic oil lasts for longer than regular oils. It is more costly. It may result in lower oil consumption.
- To prolong the life of your engine oil, you can add additives. Cooler additives can be inexpensive and help in the dissipation and absorption of heat in oil. Check with a mechanic to make sure the additives are compatible with your engine.
FAQs about How to Reduce Oil Consumption In Cars
Can Thicker Oil Reduce Oil Consumption?
Yes, a higher viscosity oil will perform better in high temperatures. If your old oil is used more, it could be because it is thin and burning at high temperatures. High-viscosity oil can effectively lubricate engines at high temperatures.
What Is The Best Motor Oil To Reduce Oil Consumption?
You can lower your oil use by using synthetic oil. Synthetic oil burns similarly to ordinary oil, but it lasts longer. In an experiment, when the oil was used for 6 hours at 400 degrees, it was discovered that synthetic oil lost only 4% of its quantity, whereas conventional oil lost 30%. Synthetic oil typically lasts 2,500 to 5,000 miles longer than regular oil.
Does Driving Faster Use More Oil?
The pressure on the engine's seals and valves increases as RPMs increase. When the car is moving fast, it requires more cooling and lubrication. This can result in increased engine oil consumption.
What Are Some Of The Engine Oil Additives That Stop Burning Oil?
Many aftermarket additives can minimize engine oil consumption. These additives either function as a cooler to keep the oil from heating up or thicken the engine oil to keep it from burning at high temperatures.
Before using additives in your engine oil, you should consult a professional. Some well-known additives to reduce oil usage include Archoil AR9100, Liqui Moly 2037, Lucas 10001, and Sea Foam SF-16.
An engine that consumes more oil could indicate that it is consuming too much oil, has a leak, or is not suitable for its purpose. This situation can be solved by changing to a better oil or switching to a different oil. You should have your mechanic inspect the engine to see if there are any oil leaks, or broken parts. This will reduce oil consumption.
