Premium Oil for Severe Racing Applications
AMSOIL Synthetic 4T Racing Oil is formulated specifically to handle the severity of Briggs & Stratton modified competition engines used in kart, junior drag, quarter midget and other racing applications and is recommended for any four-stroke air-cooled competition engine, whether single- or multi-cylinder, splash- or pressure-lubricated.
Combining the protection qualities of a heavy oil with the performance benefits of a light oil, Synthetic 4T Racing Oil helps racers elicit the most horsepower and longest life from their engines. It provides outstanding protection in both stock karts and limited-mod kart applications running over 10,000 rpm, with no sacrifice in horsepower. Racers using competing oils need both a light and a medium oil to achieve a similar combination of protection and horsepower.
Synthetic 4T Racing Oil was dyno-tested using the Briggs & Stratton Animal engine, and proven to provide outstanding performance in the most-extreme conditions possible. It effectively resists the elevated heat common to high performance racing engines, and it protects against the formation of corrosion between races and during longer storage periods.
