Will the new BMW models burn engine oil?
2 Answers
New BMW models do not burn engine oil. Consequences of burning engine oil: Burning engine oil can lead to incomplete combustion in the engine's combustion chamber, resulting in increased carbon deposits, reduced vehicle power performance, and sluggish acceleration. It also increases fuel consumption and worsens exhaust emissions, potentially exceeding pollution standards, thereby increasing the owner's financial burden. Solutions for burning engine oil: It is necessary to inspect the entire engine oil lubrication system, remove carbon deposits from combustion residues, ensure the smooth operation of intake and exhaust valves, and replace aging or damaged valve seals and crankshaft seals. Additionally, the gap between the engine cylinders should be minimized to maintain optimal engine temperature.
I previously researched the new BMW engines, and the design of turbocharged engines like the B58 series has indeed seen improvements, reducing the common oil burning issues found in earlier N series engines. Oil burning typically occurs due to piston ring wear or a malfunctioning oil separator, allowing oil to seep into the combustion chamber. The new BMW models use better materials and electronic control technology to manage the oil system, but a small number of owners still report minor oil burning, especially under aggressive driving or high mileage conditions. I recommend regularly checking the oil dipstick level—confirm it every 1,000 kilometers—and topping up with the appropriate viscosity oil as needed. Don’t ignore any signs of blue exhaust smoke or excessive oil consumption, as this can accelerate engine wear. With proper maintenance, the risk of oil burning is significantly reduced, avoiding unnecessary repair costs. While the factory quality of new cars is stable, paying attention to details habitually can extend your car’s lifespan.
