I see @High Performance Lubricants was on here commenting on another post. I just broke in a cam with HPL break-in oil and have actually started and driven the car off the lift, down the street and back onto the lift. I am thinking of just leaving this oil in for the next few months as I finish all the stuff still needing attention. Is there a limit for time/mileage on this break in oil? Should I dump it now and go to something else? BTW, I pulled the stick and the oil looks brand new after the break in. No metal or other visible contaminants. First year B-440 Mopar. A slightly more aggressive cam than stock but just barely. Stock internals otherwise.
