New motor need opinions on break in oil
The title says it all. I'm rebuilding a 3.0l for my truck cause mine decided to take a dump. I've bought a re-ring kit from sealed power off summit racing along with new motorcraft spark plugs and new oil. the guys at autozone told me to just add an additive of zinc. Tell me what you guys think.- 1998XLT
