Performance
AMSOIL SEVERE GEAR® SAE 250 provides performance beyond that possible with conventional gear oil. This AMSOIL custom product offers superior gear and bearing protection, better friction and heat reduction, increased efficiency and extended service life.
Superior Film Strength
Controls Thermal Runaway
Rust and Corrosion protection
Reduced Operating Temperatures
Improved Efficiency
Longer Oil, Seal, & Equipment Life
Temperature Extremes
AMSOIL SEVERE GEAR® EP SAE 250 excels in hot and cold temperature extremes. By design, it resists breakdown from high heat, preventing acids and carbon/varnish formation. Their waxfree construction also improves cold flow properties, improving fuel economy and cold weather shifting.
Applications
AMSOIL SEVERE GEAR® SAE 250 is primarily for severe racing applications..
Recommended for use in differentials, manual transmissions and other gear applications requiring any of the following specifications: API GL-5, MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037), Mack GO-J, or the differential (hypoid) gear oil specifications from all domestic and foreign manufacturers such as GM, Ford and Daimler Chrysler. Can also be used in axles where an API GL-4 lubricant is recommended.
AMSOIL SEVERE GEAR® SAE 250 is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive
As a note, we have found that the use of really heavy gear lubricants can reduce rear wheel power levels by 4-8 whp. This is on NA 4 cylinders with around 200 whp. We have not seen power losses on high powered turbo cars as the thick lube probably reduces friction by reducing metal to metal contact. We feel that Amsoil Extreme GEAR SAE 250 will probably react in a similar way.
We will update you on how well this lube works under racing conditions in the future.
