This is all I have every use on the shee I currently have. It is good quailty oil & I change it about twice a year. It only cost $4.79 a quart at my local advance auto parts store. To remind you, I ride my shee alot & hard plus the oil still isn't broken down when I change it every six months. I change it then for piece of mind. I use to run AMS oil & that's good oil too, but I can't beat this quailty of oil for the price. I'm sticking with valvoline 10w 40 motorcycle oil because it's CHEAP for #1 & last a longtime & convenient.
