I just got my new 604 in the car and primed the engine oil system for a good bit. Oil was trickling out all pushrods after a long prime. I used BradPenn break in oil. I've had good luck with it in race engines so I stuck with it. My question is this... Several local racers in crate who helped me get going say to do 1 race on the break in oil and dump it and the filter. Should I be nervous about their advice? I can't say they have engine trouble and they run every weekend. I was just a little nervous about running the break in oil for a race. Is this procedure common? I wish I could afford to run Joe Gibbs once I get switched over to race oil. Thanks guys.
