I've been trying to overcome over changing my oil for a while, and I think I will finally give it a try. I will be using M1 or PP, 2006 Mustang V6, 152,xxx miles. Leaks/burns no oil between 4k-5k oci's. 90% city driving. Without doing a Uoa, how far would you guys run it? It has seemed fairly difficult to find many uoa's on this motor. I'm thinking 7.5-8k?
