Is it ok to run Mercury Quicksilver 2 stroke outboard oil in Zens & RCMK's?
I have gallons of the stuff for my big boat & it's pretty expensive so wonder if it will be ok in the small ones?
Yes it works fine. Mix it 8oz per gallon and go. I do personally prefer a good synthetic, but this works ok, I use it to break in my engines. This is actually all I ran this season, as it was recommended by CC Racing and it works fine.
