Wait wait.. My friend (he gets a really big head about shit and if you contradict him he basically gives you the bird). Anyways he kept telling me not to use synthetic in my new engine... I used Regular straight oil for 1500miles for the break in and went to synthetic blend. He still to this day tells me that that engine spun a rod because of the type of oil I used.
Was I alright using synthetic? or was I wrong...?
