What is the drain interval with Mobil 1 Racing 0W-50?
Oil drain intervals in racing conditions can vary widely.  Depending on specific racing applications and conditions, intervals of 500 miles or more are attainable.  When determining the correct interval at these extreme conditions, used oil quality should be monitored as each application and environment can be different.

Do we need to run break-in oil before using Mobil 1 Racing 0W-50?
There is no need to run a special break-in oil if using Mobil 1. Mobil 1 has a robust additive system which helps provides protection during break-in as well as normal operation.

I've been using Mobil 1 15W-50 in my race car.  How are these new oils better/different?
Mobil 1 15W-50 is a higher viscosity oil that delivers a thick oil film for protection of high performance engines. While Mobil 1 15W-50 can be used and is recommended for both street and track use, the new Mobil 1 Racing oils are not recommended for general street use where vehicles use catalytic exhaust converters. Mobil 1 Racing™ 0W-30 and Mobil 1 Racing 0W-50 are lower viscosity oils designed to protect the engine under high output conditions in high operating temperatures. Additionally, Mobil 1 Racing Oils offer boosted levels of anti-wear protection (nominal zinc level of 1850 ppm) for extra engine protection in highly loaded flat tappet engine designs like those used in the NASCAR Sprint Cup series.

Are Mobil 1 Racing oils compatible with a wet clutch engine?
These oils are not recommended for wet clutch applications due to their high level of molybdenum.

Are Mobil 1 Racing oils the exact formulation used by the Formula 1, NASCAR, and Le Mans race teams?
Mobil 1 Racing oils are formulated with the same race-proven, fully synthetic technology used in racing applications around the world.  However, typically, Mobil 1 tailors its racing oil technology based on the specifications required by specific teams and/or race applications.

You say that Mobil 1 Racing oils are not for street use.  Why is that?  Does that mean I can't use these oils if my race car is also my daily driver?
Automotive street use oils that meet the latest industry standards are required to have a lower level of Zinc and Phosphorus anti-wear chemistries than oils formulated years ago.  The latest automotive street use engine oils are designed to be compatible with emission control equipment.  Mobil 1 Racing oils are formulated with anti-wear (Zinc/Phosphorus) chemistries at twice the level of automotive street oils to provide enhanced protection of highly loaded valve train systems found in some race engines.  Based on the high level of anti-wear chemistries, Mobil 1 Racing oils are not recommended for street use.

Zero weight oils are thinner.  Will using a 0W oil cause excessive engine wear while racing or qualifying?
Mobil 1 Racing oils employ fully synthetic, latest generation, wide viscosity grade racing oil technology, designed to help reduce engine friction and protect the engine under high output conditions in high operating temperatures. Both Mobil 1 Racing 0W-30 and Mobil 1 Racing 0W-50 motor oils offer boosted levels of anti-wear protection (nominal zinc level of 1850 ppm) for extra engine protection in highly loaded flat tappet engine designs.
