synthetic basestocks fortified with SuperSynTM anti-wear technology, this advanced-protection motor
oil is engineered to deliver maximum horsepower in all engine types and sizes.
Benefits of Mobil 1 Racing 0W-30:**
Has boosted levels of anti-wear protection – well beyond those of ordinary motor oils – to help protect engines even during grueling racing applications.
Maximizes power output by reducing internal friction.
Has outstanding shear stability and a robust additive package to help reduce oil breakdown and help extend engine life, even under the most extreme conditions.
Compared to conventional racing oils and higher-viscosity
synthetic motor oils, it provides faster flow to critical engine parts at low temperatures.
Delivers exceptional high-temperature protection, even at temperatures up to 400ºF (204ºC).
Applications:
Mobil 1 Racing 0W-30 is intended for professional and amateur "weekend" racecars, as well as modern high-output engines of all kinds. It is ideal for supercharged, turbocharged and high-revving, high-performance engines used in street applications.
