Maxima Engine Oil

Race-Proven Engine Oil Formulated for Powersports Performance

When it comes to engine oil engineered specifically for motorcycles, ATVs, side-by-sides, and V-Twin machines, few names carry as much weight as Maxima Racing Oils. Engine oil is one of the brand's most critical product categories — and for good reason. Founded in 1979 and headquartered in Southern California, Maxima has spent over four decades formulating, blending, and bottling lubricants in-house, building a reputation validated by hundreds of championships across virtually every segment of powersports racing.

A Lineup Built Around Every Powersports Engine

What sets Maxima apart in the engine oil space is the depth and specificity of its product range. Rather than offering generic all-purpose motor oils, Maxima develops formulas targeted to the unique demands of specific engine types and applications:

• Pro Plus+ Full Synthetic 4T Oil — A race-grade, full synthetic 4-stroke oil engineered for high-RPM motorcycle and ATV engines, delivering maximum protection and performance under sustained heat and stress.
• EXTRA Synthetic 4T Oil — A triple ester-based 100% synthetic 4-cycle oil featuring an advanced additive system that reduces friction and engine temperatures, available in viscosities including 10W60.
• V-Twin Engine Oil — A mineral-based 4-stroke oil specifically formulated for V-Twin engines, featuring an advanced polymer system that resists mechanical shearing and heat breakdown for exceptional viscosity retention.
• Premium HP Mineral 4T Oil — A highly stable, long-life multigrade motorcycle oil available in 20W-50, designed for riders who prefer conventional formulations with performance-grade additives.
• SxS Full Synthetic Engine Oil — Engineered for side-by-side machines from brands like Polaris and Can-Am, with viscosities such as 5W-50 and 10W-50 to handle turbocharged and high-output engines.
• Scooter 4T Oil — A mineral-based 4-stroke oil formulated for modern free-revving scooters and mopeds, balancing protection, performance, and fuel efficiency.

Why Riders Trust Maxima Engine Oil

Maxima is notable for being a true manufacturing company — it formulates, blends, and bottles its oils rather than simply labeling third-party products. This hands-on approach means every formula is developed with real-world racing feedback. The brand's credibility is underscored by its recognition in the Racer X 2021 Readers Choice awards, where Maxima was voted No. 1 for Best 4-Stroke Engine Oil and Best 2-Stroke Pre-Mix Oil. Maxima also collaborates directly with OEM engineers to develop formulations that complement specific engine designs — a level of technical partnership that keeps the brand at the forefront of lubrication technology.

Whether you ride a high-strung MX bike, a trail-pounding ATV, a Milwaukee-Eight-powered cruiser, or a turbocharged SxS, Maxima's engine oil lineup offers a purpose-built formula to protect and maximize performance across every ride.
