Red line, Cam 2-blue blood. Anything with a high zinc content is good for break in.

Do they sell that at autozone/advanced? I'm trying to steer away from having to have all of this oil shipped seeing is how i'll be doing the oil changes often with it being a new motor.

mr.beachcomber

Our Advance Auto carries the Comp Cams break-in oil. I've used Auto Zone for my initial firing oil (Valvoline conventional) and 1,000 miles break-in oil (Valvoline VR-1 racing conventional) in the past just because they always seemed to have it on sale when I needed it.

I don't rebuild that many engines; however, the local shops that do recommended I have at least 1,000-1,500 miles on the engine before switching to synthetic. The VR-1 has high levels of phosphorous (1300 ppm)/zinc (1400 ppm) with some detergent according to their product data sheet.

Hope this helps!

Lucas oils makes an additive for break in with a high zinc (ppm) you could use that with regular mineral oil, If you don't want to have oil shipped.

ASE told me to use Rotella 15-40 for my clean out and break in oil ( 2 changes in less than 500 miles) then I switched to VR-1 racing oil

Probably good idea to use a filter magnet as well.
