AMSOIL Long Life Synthetic Gear Lubes are extended drain gear lubes engineered specifically to last several times longer and protect gears better than all conventional gear oils.

They maintain their viscosity during extended service for maximum wear control and they are fuel-efficient. The superior cold temperature fluidity and high temperature stability properties of AMSOIL Long Life Synthetic Gear Lubes make them excellent for all-season use. Equipment lasts longer and maintenance costs are reduced with AMSOIL Long Life Synthetic Gear Lubes.

Where service intervals are unavailable, drain at twice the interval for conventional oil.Note: AMSOIL does not support extended drain intervals where water contamination occurs. Check and service the gear oil frequently when water contamination is possible.Gear oils should be changed more frequently when operating vehicles or equipment in dusty or dirty conditions unless the gear system is properly sealed and equipped with membrane type breathers.AMSOIL LONG LIFE SYNTHETIC GEAR LUBES are compatible with conventional gear oils, however mixing oils reduces the benefits and nullifies the extended service life recommendations.AMSOIL LONG LIFE SYNTHETIC GEAR LUBES are compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.AMSOIL LONG LIFE SYNTHETIC GEAR LUBE 75W-90 replaces competitors' 75W-90 and 80W-90 viscosity grades

Best gear oil

Setup gears and lockers for off road use. Always recommend or install Amsoil gear lube after my work is done. Feel very confident in a successful job especially when using this lube.

Confidence in Amsoil

It's difficult to give a review of a long term oil such as differential lube. But, Amsoil in my 4.2 and my 4.0 Jeep engines was immediately noticed. Jeep in-line 6 motors tend to have valve noise on start up. Totally gone now ! Love that Amsoil ( 10w30). Now switched all 3 Jeeps to Amsoil

Lasts longer than conventional gear oil-worth the extra cost

Put this in my 2wd Tacoma open differential, 10,000 miles so far and no issues. I purchased the premium AMSOIL synthetic product for its superior quality and long service life... will last longer and protect my vehicle better than conventional, so in the long run it's definitely worth the added cost.
