Which Cars Have More Severe Oil Burning Issues?

[McRose]

Audi vehicles are known to have more severe oil burning issues. Below are the specific reasons for oil burning: 1. Worn valve seals: Valves are designed to prevent oil from leaking into the combustion chamber, but over time, they can wear out or age. Severe wear can affect the sealing performance of the valves, leading to oil burning. 2. Excessive piston gap: With prolonged use of the car, carbon deposits from incomplete combustion can accumulate on the piston rings. If not cleaned for a long time, this can enlarge the gap between the piston rings and the cylinder, allowing oil to enter the combustion chamber and cause oil burning. In severe cases, it can even lead to engine seizure. 3. Driving habits: Frequent rapid acceleration and prolonged high-speed driving can easily damage the lubricating oil film, resulting in poor engine lubrication and wear on certain components, which may also lead to oil burning. 4. Excessive oil level: If the oil level is too high and exceeds the maximum mark, the excess oil can easily enter the combustion chamber (due to excessive internal pressure) and form gummy carbon deposits.
