Specifically Engineered for 500,000-Mile Service Life in Over-the-Road Trucks – A Major seller here in Sioux Falls.
Sioux Falls’s best selling Differential Gear Oil requiring GL5
Synthetic Warehouse note: Although marketed for OTR trucking, it’s also our best seller for most of our pick-up truck customers. Still many times better wear protection than the best leading brand, but where the application isn’t needing the severe gear for extreme abuse. This is my best choice for all trucks being used as intended and at their peek tow and load capacities. Also enjoy amazing performance in winter. Another reason it’s our #1 differential oil is because it is available in GALLONS! (also quarts, quart case, 5-gallon tubs, 4-gallon case and various drum sizes.
AMSOIL’s Long Life Synthetic Gear Lube 75W-90 is an extended-drain gear lube engineered to last several times longer and protect gears better than conventional gear oils. This exclusive AMSOIL formulation of premium synthetic base oils and high-performance additives resists acid, carbon and varnish formation from oxidative breakdown. Components run cleaner and last longer. AMSOIL Long Life Synthetic Gear Lube is shear-stable and reduces friction. It maintains its viscosity during extended service for maximum wear control and is fuel-efficient. The superior cold-temperature fluidity and high-temperature stability properties of AMSOIL Long Life Synthetic Gear Lube make it excellent for all-season use. AMSOIL Long Life Synthetic Gear Lube helps extend equipment life and reduce maintenance costs.
AMSOIL Long Life Synthetic Gear Lube, in the correct viscosity grade, is recommended for domestic and foreign applications, including over-the-road trucks, light-, medium- and heavy-duty trucks, off-road equipment, commercial vehicles, motor homes, autos, SUVs, emergency vehicles, buses, delivery/utility vehicles and tractors.
Use AMSOIL Long Life Synthetic Gear Lube in differentials, manual transmissions or other gear applications where one or more of the following standards are specified: API GL-5 & MT-1, MIL-PRF-2105E, Dana SHAES 234 (Formerly Eaton PS-037) for 250,000 miles, Dana SHAES 256 (Formerly Eaton PS-163) for 500,000 miles, Dana SHAES 429A, Mack GO-J & GO-J+, Meritor 0-76N (75W-90) & 0-80 (80W-140) plus hypoid gear oil specifications from ZF TE-ML 07A and 08 foreign and domestic manufacturers such as GM, Ford and Daimler Chrysler. It can also be used in rear axles where API Service GL-4 lubricant is recommended.
AMSOIL Long Life Synthetic Gear Lube provides:
- High Load Gear and Bearing Protection
- Protection from Rust and Corrosion

For product service life in differentials, consult your owner’s 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 owner?s manual, whichever is longer||Drain at 50,000 miles of service or according to the owner?s manual, whichever is longer|
|Heavy Duty Class 8 Line Haul||Follow the OEM drain interval (miles or hours) for synthetic oil up to 500,000 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 owner’s 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 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 Lube is compatible with conventional gear oil. Mixing AMSOIL gear oils with other oil, however, reduces the oil’s benefits and nullifies the extended service life recommendations.
AMSOIL Long Life Synthetic Gear Lube is 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. AMSOIL Long Life Synthetic Gear Lube 80W-140 replaces competitors’ 80W-140 and 85W-140 viscosity grades.

Note: This product fits the bill for most of our truck differential applications. I will generally suggest upgrading to the Severe Gear version (industry best) if the differential is overworked, worn, or most often when the differential is undersized for the job or there are cooling issues due to a small sump.
