Is it okay to run JGD synthetic oil in a roller follower camshaft or OVC engine?
Yes. Joe Gibbs Driven Racing Oil features enough anti-wear chemistry to protect flat tappet lifters, and it is safe to use with roller-follower camshafts and lifters. In fact, our Nationwide Series engines (formerly known as the Busch Series) use roller-follower camshafts and lifters, and we use the same XP1 oil in those engines that we use in our NASCAR Sprint Cup Series flat-tappet camshaft engines.
