- Delivers maximum horsepower and cooler engine temperatures, promoting improved lap times and longer-lasting components.
EXCELLENT ALL-TEMPERATURE PERFORMANCE

- Maintains superior film strength in extreme heat.
- Thermally stable synthetic chemistry resists the effects of intense heat common to racing engines to provide reliable protection for the duration of the race.
