Probably gonna get flamed
I know there is a million and one oil threads on here but I don't know if this particular one has discussed before, I couldn't find a thread but if ther is one just let me know. Anyway, I got my bike and I don't know what the last owner used for oil. Ive tried to get in touch with him but its a complicated situation, Anyway, I was wondering if he didn't use full synthetic is it safe to go straight to a full syn oil or should I first do a syn blend and then go to a full syn. Or if he did and I used nonsynthetic, but changed the oil after say 1K miles would that cause any damage. Ive heard that once a full syn has been used you are suppose to ween it back to regular oil slowly. I plan to use a full synthetic but I want to do some more research to find out which is the best to use. Everyone seems to have their own opinion so I need to form my own opinoin.
