Does the current Passat consume engine oil?
1 Answers
Passat vehicles do experience engine oil consumption. More information about engine oil consumption is as follows: 1. As long as the engine is running, there will be engine oil consumption, the only difference being the amount. A small amount of oil consumption is normal, but if the oil consumption is too high, it is necessary to go to a professional repair shop for inspection and maintenance to eliminate faults; 2. Engine oil consumption design value: This is the normal engine oil consumption considered during the design of the car. For imported foreign models, this value is generally 0.1-0.2g/kwh, and it is higher for German models. In China, the regulation states that engine oil consumption should be less than 1% of gasoline consumption to be considered normal; 3. Engine oil consumption calculation formula (only an approximate calculation): Engine oil consumption = (mileage/average speed) * car power * engine oil consumption design value. 4. There are certain reasons for engine oil consumption: Engine oil has the function of lubricating pistons, piston rings, and cylinders. When the piston engine is working, there is a layer of oil film on the inner wall of the cylinder. During the combustion of the mixed gas, part of the oil film will be burned off by the high-temperature combustion gas; The engine oil used to lubricate the intake valve stem will also be sucked into the combustion chamber. High-temperature exhaust gas will also consume the engine oil used to lubricate the exhaust valve; As the engine working time increases, the steam generated by the high-temperature oxidation of the engine oil will be sucked into the combustion chamber through the crankcase forced ventilation valve for combustion.
