Resists High Temperature Vaporization
Conventional motor oil tend to vaporize and lose weight in high temperature conditions, contributing to poor Oil circulation, reduction in fuel efficiency and excessive emissions and engine wear. AMSOIL Formula4-Stroke PowerSports 0W-40 synthetic Oil is highly resistant to evaporation. While conventional petroleum Oil thicken due to evaporation, AMSOIL Formula 4-Stroke Synthetic oils maintains its viscosity in high temperature service. The superior evaporation resistance of AMSOIL Formula 4-Stroke Synthetic oil reduces engine wear, Oil consumption and emissions while keeping Oil circulation efficient and fuel economy high.
Friction Modifier Free
AMSOIL Formula 4-Stroke PowerSports 0W-40 synthetic oils contains no friction modifiers, making it ideal for ATV, outboard motor and motorcycle engines. The friction modifier free formulation of AMSOIL 4-Stroke ensures transmission (manual or automatic) and clutch compatibility and prevents slip.
Performance Formulated
AMSOIL Formula 4-Stroke Synthetic oil contains a robust dispersant/detergent package, making it ideal for use in high-stress four-cycle engines. The dispersant/detergent additive package effectively suspends harmful combustion by-products and prevents deposits, keeping AMSOIL Formula 4-Stroke clean and serviceable.
High-temperature operations often lead to the thermal degradation and oxidation of conventional Oil, leading to the formation of deposits, sludge and varnish. The superior oxidative and thermal stability of AMSOIL Formula 4-Stroke Synthetic oil inhibits the formation of varnish, deposits and sludge so equipment runs clean in high-stress, high temperature operations.
Temperature and Performance
AMSOIL Formula 4-Stroke PowerSports 0W40 motor oils has a broad viscosity range, making it excellent for use in both hot and cold temperature extremes. As an SAE 40 weight motor oils, AMSOIL 4-Stroke PowerSports 0W40 provides superior protection for hot operating, hard working motors, while its SAE 0W rating ensures easy cranking, excellent cold weather starting and quick post-startup protection.
Copper Corrosion, Rust and Foam Inhibition
AMSOIL Formula 4-Stroke Synthetic oil protects equipment from copper corrosion and rust, even during equipment storage. AMSOIL Formula 4-Stroke Power Sports 0W-40 motor oils does not foam in service, protecting equipment from the metal-to-metal contact and wear that occurs with use of foam-filled fluids.
SERVICE LIFE
Recommended for use up to twice the motorcycle manufacturer change interval (miles/hours) or one year, whichever comes first, in engines and transmissions. When using an engine filter other than AMSOIL EaOm Motorcycle oil filter, change the filter at standard intervals.
Note: Racing or modified engines are excluded from extended drain interval recommendations. Oil changes are at the owner's discretion.
