I have also learned that it is best to use Rotella-T oil for the breakin process. The new oils on the market don't have the protection that they once had.

I have used this process changed the oil after 600 miles again at 3000 miles and after 6000 miles changed to synthetic oil. This is only my opinion, but it has worked for me.

Each person has their own opinion on what oil to use and when to change it.
