NITRAK ZR25 is a 100% synthetic, high-performance 2-stroke oil specifically engineered for kart racing engines. Its advanced blend of synthetic esters, high-shear polymers, and top-tier racing additives ensures maximum lubrication, thermal protection, and clean combustion even under extreme track conditions.
Key Technical Features
- Fully synthetic base (esters + PAOs)
Exceptional thermal stability, reduced evaporation loss, and strong film strength at high RPMs. - High-load anti-wear protection
Reduces friction between piston, rings, bearings, and cylinder, preventing seizure and scoring even in endurance races. - Low ash / clean burn formula
Minimizes carbon deposits on pistons, spark plugs, and exhaust ports, preserving engine performance over time. - Extreme temperature stability
Maintains consistent lubrication at temperatures above 200°C, ideal for air- or liquid-cooled kart engines. - Perfect miscibility with race or pump fuels
No fuel separation or instability, even after long storage.
