So what oil do you guys use now?
My $.02 and others will have different opinions; I recommend using Yamalube. I beleive Yamaha knows what their engines need more then anyone else does.
I've been using Yamalube Full Synthetic for a few years now. (R6, WR450, and now FZ8)
Consider using YL Semi or Full Synthetic, it does cost more but I think you will notice a difference. But if you are on a strict budget YL All purpose oil is more then good enough. Dont use car/truck oil
One other suggestion is use a quality oil filter. You get what you pay for. I would use Yamaha's filter or a K & N.
Enjoy your FZ!
