I just bought a new people 150. I run full synthetic oil in everything else I own. The dealer I bought the scooter from does not recommend full synthetic for my scoot. What are your thoughts, and if I change over. How soon?
We'll probably never know for sure, but yeah, the owner's manual doesn't call for
synthetic oil for that engine, and we'll never know if synthetic will make it run better
or worse in the long run.
One thing is certain though.. it's better to change cheaper oil more often then think
that using expensive oil will enable you to skip regular maintenance engine changes.
