What is the normal oil consumption rate for BMW per kilometer?
1 Answers
BMW consumes one liter of oil per thousand kilometers normally. The official standard given by BMW is that oil consumption within 0.7L per 1000 kilometers is normal, while the standard for the M series is 1.5L. More details about BMW oil consumption are as follows: Reasons for BMW oil consumption: Due to the inconsistency between domestic fuel quality and international standards, a large amount of carbon deposits can easily form in the combustion chamber during engine operation. Carbon deposits are an important cause of various engine problems, including oil consumption; carbon deposits accumulate in the piston grooves. Solutions for BMW oil consumption: Check if it is really oil consumption: In many cases, excessive oil consumption is mistakenly considered as oil burning due to oil leakage. You can place a white cloth under the engine, start the engine, and check for oil stains on the cloth to detect oil leakage; check if carbon deposits in the cylinder cause the piston rings to stick; replace the valve stem seals. The probability of BMW oil consumption caused by damaged valve stem seals is relatively high, and they can be replaced without dismantling the cylinder. Solving oil consumption by replacing valve stem seals can be considered a cost-effective method; check if the cylinder walls and pistons are severely worn with excessive clearance.
