Is break in oil on an L31 a good idea?
I finally have time to focus on getting my L31 crate motor assembled and before I did anything I asked the GM performance tech guy and he said break in oil can be used but doesnt have to be anything more than regular oil. Just not to use synthetic for at least the first 500 miles. I asked which he recommended and he said its up to the individual. What do you guys think, use the break in oil..which one? Or just regualr oil, and then as well which one? I just dont know this stuff so any help is appreciated.
