I recently redone top end on my sled new pistons and rings and mono block , I assembled it all with full synthetic oil and the sled is practically fully back together the oil reservoir is also topped off with full synthetic oil and I’ve just recently read that for break in you should use mineral oil to seat the rings better wondering what I should do, drain the resevoir and fill it with mineral and leave the full synthetic oil I used while assembling it to burn off until the mineral oil makes its way into it, would that be a bad idea? Or nothing to worry about, in terms of the quick change of oil in reservoir if I where to go that route. Or would leaving it the way it is be alright? Responses very much appreciated!!!
