Which BMW 5 Series Model Doesn't Burn Engine Oil?
3 Answers
Most BMW models experience engine oil consumption, which is a common phenomenon among German cars. Generally, this isn't a major issue as long as proper maintenance is observed. "Burning engine oil" refers to the situation where oil enters the engine's combustion chamber and participates in combustion along with the air-fuel mixture. Here's some additional information: When a vehicle burns engine oil, it can lead to premature failure of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, reduced acceleration power, higher fuel consumption, and excessive exhaust emissions. In severe cases, insufficient engine lubrication may cause irreparable damage or even complete engine failure, significantly increasing repair costs and potentially creating safety hazards.
I've been driving a BMW 5 Series for over a decade, and I feel the oil consumption issue mainly affects early models, especially the E60 generation produced between approximately 2003 and 2010, where high oil consumption was common with N52 or N54 engines. The later F10 generation post-2010 showed some improvement, but still had potential issues. The current new G30 generation, manufactured after 2017 with B48 or B58 engines, has optimized piston rings and cylinder sealing in its design. My 2019 530i rarely requires topping up oil, only needing checks every 10,000 kilometers on average, which is quite worry-free. BMW has updated its technology to address the oil consumption problem, so if the budget allows, going for a post-2017 G30 model is the safest bet. Just use genuine oil during maintenance to avoid recurring issues.
I have some knowledge about engine design. Previously, the N-series engines in the BMW 5 Series, such as the N54 in the E60 and early F10 models, were prone to burning oil due to rapid piston ring wear or oil seal failure. However, the newer B-series engines like the B58 in the G30 and newer G60 models have been improved with more durable materials and precise control systems, reducing oil consumption. It's advisable to drive gently and avoid aggressive throttle inputs to extend component lifespan. Regular oil and filter changes are also crucial. I recommend choosing models with fewer issues within 60,000 kilometers, as those from 2017 onwards are generally more reliable. With technological advancements, BMW has also addressed some issues in older vehicles through recalls. Always check the vehicle history report before purchasing to avoid potential pitfalls.
