Direct fuel injection (DFI), sophisticated computer programming, targeted electronic oil injection and other developments have enabled a new era in two-stroke powersports engine design. Modern engines offer an unprecedented combination of increased power, improved fuel efficiency and reduced emissions.
The increased level of performance comes at a price: Modern engines encounter increased heat, friction and stress while often using less oil to lubricate and protect vital engine parts. The Rotax® E-TEC® 800R, for example, is a liquid-cooled, DFI two-stroke engine capable of 7,900 rpm and 163.9 hp. It incorporates electronic equipment that can adjust the amount of oil the engine uses depending on operating conditions. As a result, the engine products fewer exhaust emissions, but undergoes increased severity. Durable oils formulated to provide increased lubricity are best suited for powersports engines like the Rotax® E-TEC® 800R.
This detailed and documented study compares the ability of AMSOIL INTERCEPTOR® Synthetic 2-Stroke Oil and XPS-2 Synthetic 2-Cycle Oil to protect against engine wear and deposits in a snowmobile equipped with a Rotax® E-TEC® 800R engine. The study further compares the lubricity and detergency properties of each oil using industry-standard American Society of Testing and Materials (ASTM) testing, demonstrating that INTERCEPTOR® exceeds the performance requirements of high-performance DFI snowmobile engines in severe operating conditions.
Not only does AMSOIL provide performance, protection and peace of mind, AMSOIL delivers it all for less than the OEMs do.
