went to walmart last night, thought I'd get some 2stroke oil and add that next time I fill up. All my local wally world had in stock was their super tech stuff. I got the stuff that you normally would mix with gas. It didn't however say anything about it being low ash. Did I get the right stuff? the only other thing they had was their super tech outboard engine 2-stroke oil like you would use in something that has oil injection, like a snowmobile. thats not the stuff I wanted is it?
