About Extreme Racing Oil
Extreme Racing Oil is the performance lubricant brand behind LJ1 Oil Products, a specialty manufacturer based in House Springs, Missouri, with deep roots in the motorsports community. Founded with a singular focus on giving racers a competitive edge, LJ1 has built a reputation for formulating oils and fluids that are engineered from the ground up for the punishment of the track — not just adapted from everyday street-use products.
What separates Extreme Racing Oil from off-the-shelf alternatives is its commitment to high-performance chemistry. Extreme Racing Oil engine oils are built on API service level SJ additive technology and feature an elevated zinc (ZDDP) package — the synthetic blend racing oils deliver 2200 ppm Zinc and 2500 ppm Calcium, with an additional boost of ZDDP to provide excellent anti-wear protection . This elevated zinc concentration is critical for high-lift camshafts, flat-tappet engines, and high-revving race motors that demand more from their lubrication than a standard API-rated oil can offer.
The use of these anti-wear and detergent additives, blended in quality paraffinic base oils, makes these motor oils ideal for protecting an engine under extreme conditions, while utilizing a mixture of synthetic and conventional base stocks for extra performance and protection from oxidation that causes engine deposits.
Extreme Racing Oils are recommended for high-performance engines where exceptional engine protection is needed, and are not intended for use in engines equipped with catalytic converters, as the concentrated additive formulation can damage emission control components. This makes them purpose-built for dedicated race vehicles, circle track cars, drag racers, and off-road competition machines.
The brand's credibility on the track is well established. Extreme Racing Oil has earned the trust of racers at events like the US Street Nationals, with customers from Summers Motorsports among those claiming victories in multiple classes. Beyond individual achievements, the brand continues to grow its presence throughout the grassroots racing community.
LJ1 Oil Products also rounds out its lineup with premium ATF and hydraulic fluids, diesel engine oils, street performance oils, and a full suite of automotive care products — making it a versatile supplier for both dedicated racers and performance-oriented everyday drivers.
