Re: synthetic oil questions
I changed mine over to mobil 1 5w-40 for the winter. i keep mine in a heated garage and it seems to start a lil easier, injectors are a tad quieter. no performance gains are noticed, throttle response the same. When it sat outside in the cold that 5 weight makes it alot happier when starting. hope this helps.
