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).
Engineered with an exclusive full-synthetic ester formula, these top-tier products are meticulously crafted to cater to various vehicles, including passenger cars, light trucks, performance vehicles, and marine applications. Offering an unparalleled level of quality, they boast an extensive range of viscosity options, ensuring the highest standards in the current market.

It contains a special friction modifier for limited slip differentials and promotes smooth shifting in both cold and hot conditions. Red Line 75W90 exceeds API GL-5 specifications and can be used in transmissions requiring 75W, 80W, or 85W GL-4 gear oils, as well as SAE 30 or 5W/10W30 motor oils. For specific requirements like SAE 90 GL-5 gear oil, Red Line offers compatible alternatives like 75W90NS or 75W140NS Gear Oil.

Much like a newborn child, the first few moments of your engine's life are crucial for its long-term well-being. Don't let your hard work go to waste - use Red Line assembly lube to protect engine components during those first vital moments after initial start-up, when no lubrication is present. Red Line's special formula provides 3x more film strength than conventional assembly lubricants, and it works great as a corrosion inhibitor during those long-term engine builds that spend a lot of time in storage. Best of all, it's designed not to clog filters like many assembly lubricants have a tendency to.

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.
