I'm thinking about running 10-30W Valvoline VR-1 racing oil for the start up of a new engine that has a roller cam and roller lifters. I'm also planning to use some Lucas ZZDP additive. I plan to stay with the VR-1 down the road as well. My question has to do with regular vs. full synthetic. Also, would you continue to add the ZZDP on all future oil changes?
