Redline Oil 10W-40 Motor Oil - 1 Quart

Redline Oil's 10W40 Motor Oil is the go-to choice for medium and heavy-duty gasoline engines in light trucks, as well as high-performance engines used in street/strip or track activities. This oil excels in applications where high oil temperatures are common, offering enhanced protection for engines under extreme stress. At operating temperature, it provides a robust oil film similar to a petroleum-based 20W50, ensuring superior protection against wear and heat in demanding environments.

Formulated with Redline’s premium full-synthetic ester/PAO base, this 10W40 motor oil delivers unmatched protection and efficiency across a variety of operating conditions. It meets or exceeds API SN/SM/SL/SJ/SH/SG/CF and ACEA A3/B3/B4 standards, ensuring compatibility with a broad range of vehicles and performance applications. Redline’s 10W40 offers excellent wear protection and friction reduction, making it ideal for high-performance engines subjected to street, strip, or track use.

With high detergency for extended drain intervals, this oil maintains engine cleanliness while optimizing fuel economy and improving ring seal for more power. Its superior high-temperature stability and oxidation resistance ensure reliable lubrication even at elevated engine temperatures, preventing wear and extending the lifespan of critical components. The high natural viscosity index (VI) creates a thicker oil film in bearings and cam surfaces, providing extra protection under high-load conditions.

Thanks to reduced evaporation rates compared to other synthetic oils, Redline’s 10W40 helps maintain efficiency and ensures strong, lasting ring seals. Blended with polyol ester/PAO base stocks, it avoids the use of unnecessary additives, ensuring optimal lubricity and long-lasting performance. Fully compatible with both conventional and synthetic motor oils, Redline’s 10W40 is the perfect solution for drivers seeking maximum performance, protection, and reliability in a wide range of applications.
