Why is my car suddenly burning oil?
A car may be burning oil for a few different reasons. The two most common are because it is bypassing the piston rings, or leaking past the valve seals. If your engine’s piston rings are worn out from high mileage or poor maintenance they can allow small amounts of oil past to be burnt during the combustion process.
What causes excessive oil burning?
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.
Will thicker oil stop oil burning?
A lot of oil-burning takes place because an engine’s piston rings are worn out, and thicker oil won’t fix that. They also count on low-viscosity oils to reduce friction and drag (the work of simply moving the engine parts through thicker oil), which improves mileage.

Does your Subaru burn oil?
Older Subarus also burn oil. Although skipping the first year of a model change might make sense, there is no reason to wonder about the second. The car either be a good car or crap, but not a mystery. You will know about issues and whether they got fixed. After the bug fixes in the second year, the following years add features, not reliability.
