NORMAL SEVERE Cars, SUV, Light & Medium Duty 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 Truck, Commercial Equipment Follow the OEM drain interval (miles or hours) for synthetic oil up to 500,000 miles. Otherwise, drain at twice the OEM interval for conventional oil. Follow the OEM drain interval (miles or hours) for synthetic oil. Otherwise, drain at twice the OEM interval for conventional oil. 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. Aftermarket oil additives, other than those specified by AMSOIL, are not recommended for use with AMSOIL gear oils.
AMSOIL Long Life Gear Lube is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock friction modifier additive.
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.
