    Great for winter operation
    By  YANICK,  a  Verified Buyer  from  North of Quebec, Canada  on  January 24, 2021
    I was using 5W-30 on my 2009 Yamaha Grizzly 550. I winter time it was hard to start but now with the 0W-40 it's start almost like we are in summer. The only thing is I don't know how that thin oil will hold during summer time. This is where I get scare. My owner manual call for 10W-30 for summer operation.
