Is it safe to say the rings should be broke in enough to start using the regular Brad Penn oil? Or should I go a few more miles with the break in oil? This is a hydraulic roller cam setup. Thanks

If not & this is the 2nd batch I'd leave it in & here's some good (related) reading for you. "breakin secrets" at www.mototuneusa.com.

The 100 miles was pretty mild on the motor with a few stop light romps. I was just curious when I could start using the regular synthetic Brad Penn oil. Hi Rob, I didn't do a 30 minute break in due to it having a roller cam setup. Thanks Last edited by 440forPOWER; 03/30/13 04:08 PM.

As to your answer..if you call ring mfgs, engine builders, etc you will get answers all over the place. Ive decided that 500 miles, especially if you make a few hard passes, is plenty. 72 RR, Pump gas 440, 452s, 3800 lbs, Corked, ET Radials,. 11.33@117.72. Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.
