ENEOS Engine Oil: OEM-Engineered Protection for Every Drive

When it comes to engine oil, few brands carry the depth of pedigree that ENEOS brings to the table. Established in 1888 and headquartered in Tokyo, ENEOS is Japan's largest oil company — and its engine oil lineup is the direct product of decades of collaborative engineering with the world's leading automakers and race teams. These aren't lubricants reverse-engineered from industry specs; they are the factory-fill and service-fill oils trusted by major Japanese and Asian vehicle manufacturers from the ground up.

Built Alongside the Engines They Protect

What sets ENEOS engine oils apart from conventional lubricants is the relationship at their core. ENEOS has worked hand-in-hand with OEM partners to develop vehicle-specific formulations, with in-house testing facilities designed to meet each manufacturer's exact oil specifications. The result is a line of motor oils engineered to anticipate future requirements beyond current domestic standards — oils that help ensure peak fuel economy, reduced emissions, long-term durability, and maximum power output from the first fill to the last drain.

ENEOS fully synthetic motor oils, including popular viscosity grades like 0W-20 and 5W-30, are blended with high-performance hydrorefined base oils and organic molybdenum (MoDTC) friction reducers to minimize internal engine friction and deliver superb fuel economy. The 0W-20, for example, meets the latest API SP and ILSAC GF-6A standards and carries GM dexos®1 Gen3 approval — making it a drop-in choice for a wide range of modern gasoline engines.

Racing Series: Track-Proven Technology for Street and Competition Use

ENEOS takes its motorsport heritage seriously. The brand has supplied lubricants to the Honda Formula One team, the Yamaha Factory Racing MotoGP team, and competitors across NASCAR, Super GT, World Rally, and Formula DRIFT. That track experience flows directly into the ENEOS RACING Series, a dedicated product line with two distinct tiers:

• RACING PRO — Developed for extreme professional racing conditions, this line uses a 50:50 ester-and-synthetic base oil blend (10W-50) or an ultra-low viscosity base (0W-20) paired with MoDTC and ZDDP additives to unlock superior horsepower at elevated temperatures, resist oxidation, and prevent sludge build-up in high-revving engines.
• RACING STREET — Designed for performance enthusiasts who drive their cars to the track, RACING STREET combines race-grade protection with full API approval for road use. The 0W-50 variant uses 100% PAO (poly alpha-olefin) fully synthetic base oil for fast cold starts and exceptional engine component protection, while the 0W-20 uses Group III+ base oil with advanced friction-minimizing additives for modern high-performance street engines.
