Driven Racing Oil has partnered with a refinery that processes Pennsylvania grade oil to produce the GP-1 line of synthetic, high-performance engine oil. In doing so they have discovered that by simply swapping their traditional engine oil base with the Pennsylvania grade oil, engine wear was cut in half. Driven doesn’t just bench test their oils either, all products go through rigorous durability testing in an engine to correlate the physical results of the engine wear with the lab results of the engine oil analysis.
