High-performance engines run at extreme temperatures and under intense stress, particularly if they are turbocharged. The added heat and pressure invites engine wear and formation of harmful sludge if the oil isn’t formulated for this intense environment. AMSOIL Extreme Power 0W-40 100% Synthetic Motor Oil is formulated to deliver outstanding wear protection and resistance to oil consumption, even in severe conditions. It is a high-performance lubricant designed for street-driven vehicles.
