Mobil1 4T 10w-40 and Purlator filters.
Stock filters are fine as long as you change them. I was told that different filters have different flow capabilities, could cause oil starvation at certain lean angles. Don't know if that's true but I know that there is no need to upgrade the filter for typical road use.
I use mobil 1 10w-50.
we need a smilie running away from the oil topic. :tiptoe:
wow. I'm shocked that on a bike forum, no one is mentioning Rotella T synethetic.
