Conventional Oil for Performance Oil Change Interval Best Practices While the factory maintenance schedule suggests an oil change every 10,000 miles with synthetic oil, this can vary based on driving conditions. Recommended Oil Specifications For the majority of model years, the factory-fill recommendation is 5W-30 oil that meets the BMW Longlife-01 standard.
