Re: Break In and Synthetic oil

I don't think it makes a whole lot of difference .They used to ship new car engines with "break in oil " which is just a little STP type stuff .You ran it for 500-1000 miles then changed it .They stopped doing that about 10 years ago .

If I rebuild a saw engine I run it a tad rich for a few tanks then lean it out .Weather that makes any difference I really can't say .
