Red Line Oil

Born on the Track, Proven on the Street

Red Line Synthetic Oil Corporation was established in 1979 by Tim Kerrigan and Peter Filice in Novato, California, starting in a small garage where they developed two-stroke racing oils for competitive motorsports. What began as a specialty manufacturer serving the racing community has evolved into one of the most respected names in high-performance lubrication. Red Line initially focused on manufacturing oils specifically for the racing industry, but has since broadened its scope to include mainstream markets, bringing racing-grade protection to enthusiasts and everyday drivers alike.

The brand's "no compromises" philosophy has earned it a legendary reputation among professional racers and performance enthusiasts. Their product range includes a comprehensive selection of multigrade and monograde polyol ester base stock (Group V) engine and gear lubricants, formulated with PAO/Ester base stocks that deliver superior thermal stability and film strength compared to conventional oils. Today, the company operates as a subsidiary of Phillips 66 Spectrum Corporation, expanding its reach while maintaining the uncompromising quality standards that built its reputation.

Premium Engine Oil Technology

Red Line's engine oils are engineered for drivers who demand maximum protection and performance. The company offers sixteen different viscosities, each formulated with a proprietary additive package featuring enhanced ZDDP levels for exceptional wear protection. Whether you're running a street car, track-only build, or professional race vehicle, Red Line's motor oil lineup delivers measurable benefits in reduced friction, lower operating temperatures, and extended component life. From lightweight 0W oils for modern fuel-efficient engines to heavy-duty 70Wt formulations for nitro-burning dragsters producing over 11,000 horsepower, the range covers virtually every application imaginable.

Advanced Automatic Transmission Valve Body and Fluid Solutions

Transmission protection is critical for both performance and longevity, and Red Line's automatic transmission fluids are specifically engineered to handle extreme conditions. The company offers the widest selection of ATFs on the market, covering most domestic and import applications and proven to lower transmission temperatures while maximizing protection. These fully synthetic formulations provide superior shear stability, oxidation resistance, and friction characteristics compared to conventional fluids, helping transmissions shift more precisely while extending service life.

Performance Fuel Additives and Cooling Solutions

Beyond lubrication, Red Line manufactures specialized fuel additives designed to optimize combustion efficiency and clean fuel system components. The brand's innovative approach extends to cooling system products, including their famous WaterWetter formula that reduces coolant temperatures by minimizing vapor barriers on hot metal surfaces. These additives represent the same chemistry expertise and racing heritage that define Red Line's lubricant portfolio, offering measurable improvements in engine performance and reliability.

Complete Drivetrain Protection

Red Line's gear oils and automatic transmission fluids demonstrate the brand's commitment to comprehensive vehicle protection. The company designs and engineers gear oils for special applications, recognizing that one size doesn't fit all. Their ShockProof line revolutionized the manual transmission fluid market, while specialized differential oils provide superior protection for limited-slip units, heavy-duty trucks, and high-performance applications. Each formulation addresses specific mechanical requirements, thermal challenges, and performance objectives.

A Legacy of Racing Excellence

Red Line has a reputation with racers and enthusiasts alike for creating products that perform and protect better than any on the market. The brand has served as the official oil supplier for prestigious racing series and maintains partnerships with professional teams across drag racing, road racing, drifting, and motorcycle competition. This ongoing involvement in motorsports provides real-world validation for product formulations while driving continuous innovation. When components are pushed to their absolute limits lap after lap, race after race, Red Line's lubricants prove their worth where it matters most.
