How to Solve the Oil Burning Issue in the 2011 Buick LaCrosse?

[DelEllie]

If left unaddressed, the problem of oil burning can significantly impact the vehicle, and in severe cases, it may require a major engine overhaul. When oil burning is first detected, it can often be resolved without disassembling the engine. Differences Between Domestic and International Standards: These differences can cause a large amount of carbon deposits to form in the combustion chamber during engine operation, which are the root cause of various engine issues. Carbon Deposits Accumulate in the Piston Grooves: This causes the piston rings to stick together, preventing them from sealing properly. The "stuck" piston rings greatly reduce their ability to scrape and seal oil. Additionally, sludge can clog the oil return holes, preventing oil from flowing back normally and leading to increased oil consumption. Valve Stem Seal Corrosion and Aging: This results in poor sealing. Valve stem seals are among the most prone-to-aging wear parts in an engine. Virtually all vehicles with over 100,000 kilometers driven experience this issue.
