We use Schaeffer Oils in our engines (we are using 5-50 Supreme Synthetic in the 632" (right now). I used their 5-30 in my Stocker with no ill effects and it was faster than 20 Redline. (at least in my engine).

I have used Blackstone Labs to do my Used Oil Analysis. If you haven't done that I highly recommend them. You can find out EXACTLY what is going on in your engine after each oil change and monitor the change or spot early problems.

I tried the Comp Cams 15-50 Break-In oil on the dyno and when we sent it in Blackstone's rep wrote a nice email that stated it has the highest zinc, phosphorus and Calcium package they had seen in a while. He recommended I stay with it vs the Schaeffers I had been sending in, I have 10 1-gallon jugs of Schaeffers so I will use that up and go back to the Comp Cams Break-in. It is a litttle heavy for stock but with that much Zinc it might be worth running and change oil for a heads up and save the oil to use again.

I think oil filters are as important as the oil. I keep thinking K&N should be the best but my engine guy is stuck on WIX racing filtes, what are your opinions (don't want to steal the thread, sorry, I may ask that on a different thread.
