Description
xMaxima Pro Plus+ 10w50 Synthetic is a full-synthetic, ester-fortified 4-stroke engine oil engineered to deliver reliable protection, strong performance, and a confident clutch feel across a wide operating range. The formulation blends advanced synthetic base oils with a surface-active additive system, creating a robust protective film that helps reduce wear and maintain film thickness as temperatures swing from chilly mornings to hot, demanding run days. The ester backbone enhances film strength and stability, while surface-active chemistry tends to cling to metal surfaces for a cleaner, more consistent lubrication layer. This oil is designed to work with modern engines that demand steady response without sacrificing protection.
Designed to resist oxidation and maintain viscosity, Pro Plus+ aims to minimize deposits and varnish while supporting clean engine surfaces. The result may translate to smoother clutch behavior, steadier oil performance under load, and dependable lubrication during extended trips or spirited rides. While every engine responds differently, the formulation is intended to provide a balanced blend of protection, cleanliness, and reliability under a variety of operating conditions.
Performance you can count on
- Superior protection at any temperature
- Excellent clutch feel and clutch protection
- Shear stable, ester-fortified formula maintains oil viscosity and film thickness
- Proprietary additive system and synthetic base oils combine to minimize oxidation and wear
- Surface-active chemistry aggressively attaches to engine surfaces and keeps them clean
Real-world use and expectations
In daily riding or use, you might notice crisper throttle response, consistent oil performance during long rides, and a reliable clutch feel from cold starts to high-temperature operation. The formulation aims to deliver a protective barrier without excessive viscosity buildup, helping the engine respond promptly when power is requested and helping parts stay protected under heavy use. These possibilities stem from a designed balance of film strength, wear resistance, and surface-cleaning activity that works across a broad temperature window.

Maxima Pro Plus+ 10w50 Synthetic meets API SN PLUS and JASO MA2 requirements, with performance that goes beyond the minimum expectations. It is suitable for a wide range of 4-stroke engines found in motorcycles, ATVs, and power equipment.
