Product Overview

Specially engineered and formulated for maximum horsepower and protection without the shortcomings of using automotive, PAG or mineral-based karting oils in a high-revving, air-cooled, splash-lubed environment. Resists rust, corrosion and foaming. Safe for use in gasoline and alcohol-burning stock or modified engines.

MAXIMIZES HORSEPOWER

  • Engineered with specialized friction modifiers and advanced additives that reduce energy loss due to friction.
  • Combines the horsepower of a lite oil with the wear protection of a heavier oil.
  • Helps racers put more power to the ground.

HELPS REDUCE HEAT

  • Formulated with pure synthetic base oils that resist extreme heat common to air-cooled racing engines better than conventional oils.
  • Increased thermal stability helps reduce operating temperatures and guards against sludge and deposits that rob engines of power, promoting optimum engine performance and life.

FIGHTS ENGINE WEAR

  • Engineered with powerful anti-foam agents to resist foam common to high-rpm operation.
  • Forms a durable lubricating film between engine parts to protect in the most extreme conditions.
  • Helps reduce piston-ring, cylinder and valve wear for maximum engine compression and power.
