What causes engine to burn oil?
Burning oil is often the result of worn out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber.
Can an engine burn oil without smoking?
Even without blue smoke or a burning oil smell, you could have a car burning oil but not leaking. Oil consumption is a normal part of engine operation, with normal oil consumption averaging up to a quart per 2,000 miles. It can leave your crankcase low on oil.
How do you know if your engine is burning oil?

Why am I losing oil but no leaks?
Why Is My Car Losing Oil? When a car mysteriously loses oil, there are usually two possible causes: either you’ve sprung a leak, or your engine is burning it away. Though you may not see any visible signs of leakage, less noticeable parts like a worn seal or leaky rings may be the culprit.
Why is my car burning oil but not leaking?
Worn piston rings or cylinder walls.
These piston rings press against the cylinder wall and prevent combustion gases from escaping. Unfortunately, worn out rings or cylinders can lead to gaps through which gases can escape readily. More than that, oil can leak into the combustion chamber and burn off with the fuel.
Do older cars burn more oil?
On older cars with 100,000 miles or more, increased oil consumption is to be expected. At the same time, many new cars require lighter weight oils — like 0W30 or 5W20 — instead of more traditional ones like 10W30. These finer oils smoothly seep by gaskets, rings, and seals, increasing oil consumption.
Does high mileage oil help with burning oil?
It’s like a healing ointment for overused engine parts. Reduced oil consumption: High mileage vehicles tend to leak and burn off more oil than younger cars due to degraded engine seals. High mileage oil rejuvenates degraded seals, which leads to less oil consumption and burnoff.
Can thicker oil reduce oil consumption?
In some cases, using a higher viscosity motor oil can help fill the widening gap between the rings and cylinder wall, reducing oil consumption. Some vehicle manufacturers recommend multiple oil viscosities based on climate, such as 5W-20 in colder weather and 10W-30 in warm climates.
How much oil burn is normal?
It is a fact that most engines will burn some oil. The majority of manufacturers consider one quart of oil in the range of 1,500 miles to be acceptable. It should also be pointed out there are some performance vehicles that will consume a quart of oil in less than 1,000 miles and is also considered acceptable.

How much oil consumption is normal?
Oil consumption in modern passenger car engines is usually less than 0.05 %; the maximum permissible oil consumption stands at 0.5 % (all percentage values relate to actual fuel consumption). Normal oil consumption may be higher for older engine types, stationary engines and under special operating conditions.
Why do high mileage cars burn oil?
Why Is My Car Burning Through Oil So Fast? It is common for worn out parts to cause burning oil. Your car may burn oil if you have worn valve seals or piston rings. In the combustion chamber, valve seals and piston rings keep engine oil from entering.
