Does Audi Still Burn Engine Oil?
1 Answers
Audi has some models that experience engine oil burning, which refers to the engine oil entering the combustion chamber of the engine and participating in combustion along with the air-fuel mixture. Below is an introduction to the causes of engine oil burning: 1. Poor Cylinder Sealing: This is mainly due to excessive clearance between the piston and cylinder wall, improper installation or poor sealing of piston rings, allowing the cylinder wall to enter the combustion chamber, resulting in fuel burning. Poor sealing performance of the valve seal ring, damage to the crankcase ventilation valve, or blockage of the crankcase exhaust port can cause excessive pressure in the crankcase, leading to engine oil entering the cylinder along with crankcase gases and burning. 2. Choosing Higher Viscosity Engine Oil: For some older cars, engine oil burning is relatively normal. You can choose engine oil with slightly higher viscosity to enhance the sealing between the piston and cylinder wall. Of course, the ultimate solution to oil burning is a more thorough inspection and repair of the car to fundamentally resolve the issue. High-end cars typically use fully synthetic oil, and even many supercars use high-fluidity 0W-50 series supercar oil. High-fluidity oil means thinner viscosity, which allows detergents to evaporate, offering many benefits. However, a downside is that because it is thinner, the proportion of oil entering the combustion chamber from the cylinder and piston rings is higher, leading to naturally higher oil consumption compared to family cars.
