AMSOIL Synthetic Engine Oils
Choosing the right engine oil starts with the requirements of the engine. Viscosity is important, but it is only one part of selecting a suitable lubricant. Industry classifications and manufacturer specifications establish requirements for areas including wear protection, deposit control, oxidation resistance, fuel economy and compatibility with modern emissions systems.
The AMSOIL engine oil range includes specialised products for petrol and diesel engines, motorcycles, ATVs and UTVs, marine applications and competition use.

Petrol Engine Oils
AMSOIL petrol engine oils range from cost-effective synthetic oils for routine servicing through to premium Signature Series products engineered for demanding service and exceptional protection. Dedicated ranges are also available for European vehicles, high-mileage engines, hybrid powertrains and extended service applications.
Diesel Engine Oils
AMSOIL diesel engine oils cover light-duty and heavy-duty diesel applications across several distinct product series. Options include Commercial-Grade, Diesel Oil, Heavy-Duty Diesel and premium Signature Series Max-Duty lubricants for vehicles and equipment operating under a wide range of service conditions.
Motorcycle, Powersports and Marine Engine Oils
Motorcycles, ATVs, UTVs and marine engines can place very different demands on lubricants compared with passenger vehicles. AMSOIL offers purpose-designed oils for four-stroke and two-stroke motorcycles, V-Twin and metric motorcycles, dirt bikes, ATV and UTV applications and marine engines.
Racing Engine Oils
AMSOIL racing oils are developed for high-performance and competition applications where elevated temperatures, high engine speeds and severe loads demand specialised lubrication. Racing lubricants should be selected according to the engine, operating conditions and intended use rather than treated as universal replacements for street-oriented engine oils.
