All Driven Racing Oil™ engine oil products feature a synthetic base stock utilizing mPAO 100. Studies have proven that this allows air release to be five times faster than with a traditional high viscosity 100 PAO. In simplest terms, it means that Driven’s synthetic base features fewer tiny air bubbles that can cause issues such as shorter lubricant life, increased fluid compressibility, lower fluid viscosity and cavitation. Faster air release allows Driven products to last longer and work more efficiently. Just another reason why Driven products are the trusted choice of the world’s top racers, engine builders and performance parts manufacturers.
