Do I need to treat the truck any different during this break in period? Is it ok to let it idle and warm up, before I drive it somewhere?
How long do I need to leave this oil and break in fluid in the truck before changing to just straight Valvoline VR1?
Truck is running excellent, I just don't want to mess anything up.
hey nice avatar, that looks familiar!
here is some info on our recommended cam break in procedure on flat tappet cams.
i suggest dumping the oil after about 500 miles.
*** this article is probably five years old. we now use cam2 or amsoil break in oil instead of the rotella/stp combo.
