BMW Transmission & Differential Fluids

BMW transmission fluid is stated to be 'lifetime' with no maintenance necessary. That being said, if your BMW has over 100,000 miles, it is time for a filter and fluid change. Keeping this fluid and filter serviced is absolutely imperative to ensuring a long service life. Turner Motorsport carries only BMW approved fluids that will have you shifting smoothly for years to come.

Max Gear is a high-performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear—even under severe squeeze film conditions caused by extremely high loads, sudden shock loads, or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler, and longer without overhauls. It is non-corrosive to both ferrous and nonferrous metals.
