AMSOIL’s Prostar* S4 0W-50
AMSOIL’s Prostar* S4 0W-50 Synthetic ATV/UTV Motor Oil is specifically designed to provide superior performance and protection for your ATV or UTV. With its low viscosity, the oil easily moves between engine components to reduce friction and wear while providing protection against heat stress, aging and oxidation. This new oil is also resistant to oxidation, making it perfect for high-revving engines where residual oil can quickly lead to sludge formation.
Come March 14th, AMSOIL's new 0W-50 Synthetic ATV/UTV Motor Oil (AUV05) will be available to provide enhanced protection for the hard-working and performance-oriented Polaris* ATVs and UTVs. Featuring superior “cold-flow” characteristics, it enables quick starts in extreme cold temperatures - where engine damage is at its highest risk. This advanced blend of oils gives riders peace of mind by allowing them to safely push their Polaris ATVs, UTVs and four-stroke Prostar* S4 snowmobiles beyond their limits.
