Does the Audi 2.8 V6 Engine Burn Oil?
1 Answers
Audi 2.8L models do not burn oil. Engine oil naturally has a certain level of consumption, but excessive consumption can lead to oil burning issues. There are two main factors that influence oil burning: 1. Cold Engine Oil Burning: When the car's temperature has not fully warmed up, the engine exhaust emits significant blue smoke, but this normalizes after the engine warms up. This phenomenon is caused by aging valve stem seals. Due to temperature drops, the rubber material of the valve stem seals hardens, preventing a complete seal. 2. Hot Engine Oil Burning: Even after the car reaches normal operating temperature, the exhaust continues to emit blue smoke. This indicates poor piston ring sealing. Due to this poor sealing, engine oil is forced by the oil pump directly into the combustion chamber through the leaking piston rings, where it burns.
