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).

Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. ATF D4 is similar to Red Line's MTL formula and can be used in many BMW manual transmissions where MTF or MTF-LT2 is called for. The D4 ATF provides significantly improved gear protection than most OEM oils. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.

Experience unparalleled performance with Red Line CV-2 Grease, expertly crafted to endure extreme temperatures and pressures found in high-performance wheel bearings and CV-joints. This premium grease surpasses both conventional and synthetic options with its exceptional high-temperature stability, superior extreme-pressure protection, and water resistance. Operating effectively in temperatures spanning from -100°F to 500°F, it offers outstanding oxidation and corrosion resistance, minimal evaporation and oil separation, and has minimal impact on rubber seals. Expect a remarkable 200% to 800% increase in bearing life due to the exceptional extreme-pressure performance and synthetic oil fluidity. Its red moly compound outshines black moly disulfide lubricants, ensuring superior lubrication.
Red Line CV-2 Grease finds application not only in automotive settings but also in industrial environments. It excels in high-temperature alternator bearings, high-speed ball bearings, conveyor bearings, worm gear drives, servo mechanisms, and other scenarios prone to fretting wear and corrosion. Its consistency and extreme-pressure performance endure high-temperature and high-shear conditions, extending the performance life of lubricated components. Despite darkening after high-temperature use, its efficacy remains unaffected. While compatible with some petroleum-based greases, it's recommended to clean out old grease thoroughly for optimal lubrication performance and to avoid grease incompatibility.
