AMSOIL 80W-90 Synthetic Gear Lube is recommended for use under various combinations of high-speed, shock loads, low-speed and high-torque conditions. It is recommended for use in light- and heavy-duty, automotive, commercial or industrial applications requiring SAE 80W-90 EP gear lube.
AMSOIL 80W-90 Synthetic Gear Lube replaces conventional 80W-90 gear oils and is formulated to exceed the lubrication and performance requirements of front and rear differentials, transfer cases, transaxles, manual transmissions, oil-lubricated wheel bearings and steering gear boxes that require any of the following specifications:
API GL-5 & MT-1, MIL-PRF-2105E, Dana* SHAES* 234 (formerly Eaton* PS-037) for 250,000 miles, Mack* GO-J, Arvin/Meritor* O-76D plus hypoid gear oil specifications from foreign or domestic manufacturers such as GM*, Ford* and Daimler Chrysler*.
Can also be used in rear axles where API Service GL-4 lubricant is recommended.
For product service life in differentials, consult your owners manual or the Original Equipment Manufacturer (OEM) to establish the application, NORMAL or SEVERE.
|Cars, SUVs, Light Trucks||Drain at 100,000 miles of service or according to the owners manual, whichever is longer||Drain at 50,000 miles of service or according to the owners manual, whichever is longer|
|Heavy Duty Class 8 Line Haul||Follow the OEM drain interval (miles or hours) for synthetic oil up to 250,000 miles or three years, whichever comes first.|
|Vocational/Delivery||Follow the OEM drain interval (miles or hours) for synthetic oil up to 120,000 miles or three years, whichever comes first.|
|Heavy Duty Off-Road||Follow the OEM drain interval (miles or hours) for synthetic oil up to 100,000 miles or two years, whichever comes first.|
For product service life in non-differential applications, consult owners manual or the OEM for either normal or severe synthetic oil service intervals. 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 oil 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 80W-90 Synthetic Gear Lube is compatible with conventional and synthetic gear oil. Mixing AMSOIL Synthetic Gear Lube with other oil, however, will shorten the oil’s life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
AMSOIL 80W-90 Synthetic Gear Lube is compatible with most limited-slip differentials. If limited-slip differential chatter occurs, add AMSOIL Slip Lock® friction modifier additive.
