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.

Used by BMW for limited slip differentials. Rear differential fluid, also known as differential oil, is a lubricant specifically designed for the differential of a vehicle. The differential is a crucial component in the drivetrain that allows the wheels to rotate at different speeds, particularly when the vehicle is turning. The fluid helps in several ways: Lubrication: It reduces friction between the moving parts within the differential, such as gears and bearings. Cooling: It helps to dissipate heat generated from the friction and the operation of the differential. Protection: It prevents wear and tear of the gears and bearings, extending the lifespan of the differential. Performance: It ensures smooth and efficient operation of the differential, contributing to overall vehicle performance and handling. The fluid needs to be changed periodically as part of regular vehicle maintenance to ensure optimal performance and to prevent potential damage to the differential components.

Red Line 75W140 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/140 is a specialized weight used for BMW M3, M5, and M6 models with the M Variable limited slip diff (all M models since 2001). Red Line fluid is used in nearly all E46 M3, E92 M3, E60 M5 we service as well as the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in the track cars we build and prep. It may also be used in other specialized situations where a regular 75/90 will be too thin at elevated temperatures and your diff builder has approved a heavier weight oil.

Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360. An alternative to the very expensive factory BMW SAF-XJ+FM diff fluid (#83222282583).

We have been using Red Line Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs. We put Red Line Oil in our 80,000 mile street M3 and noticed smoother shifts, especially on 1-2 and 2-3 shifts. Also, our short shift kit is less notchy! For our E46 M3 racecars we used RedLine in the transmission and diff. Some of our races can go as along as 6 hours and we're happy report outstanding results. To clear up any confusion this package is what we recommend for the E46 M3. Not only do we not believe in 'lifetime' fluids, we believe that Red Line fluid will give you smoother shifts and as good or better protection for your transmission and diff internals than the factory fluids (factory fluid is also not available in a quart-sized container - we've tried).This package includes two quarts of ATF D4 and two quarts of 75/140.
