Ensuring that your BMW has high-quality and good-condition engine oil is one of the simplest ways to keep it running in optimal condition. While intervals may change depending on the model, it’s easy to monitor and inexpensive to keep up on. Oil health, therefore, should be considered high on the checklist when it comes to properly maintaining your BMW; especially when the downsides of not keeping up on it can be catastrophic.

Oil changes are arguably even more important when you aren’t sure of the history of the vehicle. There’s no hard and fast rule, but a good rule is every 7500 miles or once a year in a modern, turbocharged BMW. But changing it more frequently certainly won’t hurt anything.

Remember that the point of oil is to keep the engine lubricated and clean of impurities. If it gets too broken down, it can get sludgy and instead have the opposite effect. While modern synthetic oils have extended service intervals a lot compared to conventional engine oils, they are subject to the same (eventual) ravages over time. This why “once a…
