I was reading in "Sport Truck" magazin, they were buiding a big block motor. All things were pretty normal until I read the part where they took the crate engine, put it on the dyno, here comes my question, broke it in before any tests were done, with "30W non-detergent oil" and then chaned it to 20W50(brand omitted by me because, it ain't my brand). Has anyone ever done this with break in oil. I have always used what I was going to run in the engine. My questions are 1. Has anyone done this. 2. Has anyone ever heard of this and 3. Why would you do this? If none of this applies, how do you break in your new engines?.........Steve
