(you could use synthetic but it seems a waste of money)
This will probably start something, sorry, but I have heard over and over again do not use syn at break- in. It's almost common knowledge. Thing is, like many others, I'm betting, I have only heard "don't use syn at break-in" from people who have heard it from people, who have heard it from people, who have heard it from people, etc. etc. Just for shits and giggles, I'd like to hear from an expert, that is, some one who REALLY knows one way or the other. I don't consider an engine builder necessarily an expert unless that builder has first hand knowledge from a lubrication engineer. Other wise they are just like us,,, heard it from someone who heard it from someone...kommando said:(you could use synthetic but it seems a waste of money)
Never use synthetic for bedding in, its too slippy and the rings will not bed in, use it and you will need to fit new rings and rehone to get it to bed in properly.
Cheap dino 20/50 with good levels of ZDDP either in the oil or added.
And you know this because??kommando said:... so you can use synthetic oil from the start. But the statement still stands for any old engine with Norton tolerances.
