AMSOIL Synthetic 20W-50 and Synthetic 10W-40 Oils Are Now Reformulated for Use in Engines Subject to Extreme Stress

Both oils are now even better suited for RVs, pickups, diesel engines and all other applications subject to hard-driving performance, all applications they've been previously recommended for.

AMSOIL High Performance Oils
AMSOIL High Performance synthetic 10W-40 and 20W-50 Oils are specially formulated to protect high-performance gasoline and diesel engines.

Excellent for use in gasoline or diesel engines powering automobiles, trucks, motorhomes and equipment used in construction, farm and marine equipment as specified by the manufacturer.

Superior 12+ TBN synthetic formulation provides long service life and maximum protection against engine wear.

Runs cooler -- reduces crankcase temperature.

Note: Due to our premium additive packages AMSOIL has recommended Series 2000 20W-50 for motorcycle engines and found its performance to be outstanding. However, due to the motorcycle manufacturers attack on passenger car oils with friction modifiers (which Series 2000 oils contain) and the fear instilled in motorcycle owners, AMSOIL reformulated our 10W-40 synthetic motor oil and 20W-50 synthetic motor oil into specific Motorcycle Oils to eliminate these sales obstacles and provide top performing oils that are in line with manufacturer's recommendations.

AMSOIL Synthtic High Performance Oils in 10W-40 and 20W-50 are formulated for your hard driving engines. Pickups, commercial delivery trucks, urban delivery vehicles, tow trucks, professional service vehicles (like plumbers, electricians, or construction contractors) that put their vehicles through the most extreme stop-and-go driving. Vehicles that constantly carrying loads at or above a trucks capacity will benefit greatly from using AMSOIL Synthetic High Performance Motor Oils.

AMSOIL Synthetic 10W-40 and 20W-50 High Performance Motor Oils provide the beefier anti-wear and detergen/dispesant package that manufacturers want and discerning custumers demand.

If your business vehicles suffer from frequent downtime due to the extreme use your job demands, then consider the performance of these extreme oils. In addition, AMSOIL Synthetic Automatic Transmission Fluid, Synthetic Powershift Fluids, and Series 2000 Gear Lubes for your manual transmissions or differentials provide the complete drive train protection you need.
