Redline 10W40 Motor Oil is popular for medium and heavy-duty gasoline engines in light trucks and is the best choice for high-performance engines that see street/strip or track activity. And, it is also recommended for API SN/SM/SL/SJ/SH/SG/CF and ACEA A3/B3/B4. Red Line 10W40 Synthetic Motor Oil is a fully-synthetic ester formula for passenger cars, light trucks, performance vehicles, and marine applications that is designed to provide the highest protection, efficiency, and cleanliness, as well as superior drain intervals. It also has excellent wear protection, friction reduction across a wide range of operating conditions, high detergency that allows extended drain intervals, and it provides increased cleanliness. This formula is blended with polyol ester base stocks that feature natural multi-grade properties, avoiding unnecessary additives that hinder lubricity. Produced in only one top-of-the-line grade, these products offer the highest quality available on the market today and in the widest variety of viscosity. All products are completely compatible with other conventional and synthetic motor oils.
