Just finishing up rebuilding a small block Chevy. I am going to use synthetic oil, but I am considering using regular oil for the initial break in of the engine. My theory is that I want to have some wear on the moving parts. If you have less wear because of superior oil then the break in period must be extended. At least that's my guess. I think I want a little wear in the beginning than once I have it worn in I want no wear, no more, no how.
Being unsure of my theory I thought I would ask an experienced group what they do as far as breaking in new engines. Any help as to break in do's and don'ts and oil viscosities and helpful hint would be greatly appreciated.
Also how many miles should I have on the engine before I haul a load of gravel or mulch down the road. This is a working 3/4 ton pickup truck with a dump bed, so I do place a load on the engine.
Dave.
