What is the normal amount of engine oil consumption?
2 Answers
Engine oil consumption less than 1% of gasoline consumption is considered normal. Here are specific factors affecting engine oil consumption: 1. Oil viscosity: Lower viscosity oil has relatively poorer sealing performance, leading to increased amounts being drawn into the combustion chamber. 2. Driving conditions: High-speed driving and frequent acceleration/deceleration will increase oil consumption. Different working conditions result in varying oil consumption levels. 3. Engine break-in period: Oil consumption is relatively higher during this phase. 4. Poor fuel quality: This can easily cause carbon deposits to form in piston ring grooves, potentially leading to stuck piston rings over time; oil rings may lose their oil-scraping function, allowing oil to enter the combustion chamber through the gap between pistons and cylinder walls, resulting in genuine oil burning.
Last time during maintenance, the technician told me that consuming up to 0.3 liters of oil per 1,000 km is considered normal. My old Tiguan has 80,000 km on it and now needs half a liter top-up every 5,000 km. The repair shop said this isn't serious for turbocharged vehicles. If you notice the oil dipstick reaching the minimum mark just 2,000 km after an oil change, or blue smoke from the exhaust pipe, it might indicate piston ring sealing issues. Remember to regularly check the oil dipstick when the engine is cold, especially before long trips.
