Unfamiliar with this Klotz. I do, however, use the Wal-Mart brand 2-cycle oil from time to time and it's gettin to be that time again. :rofl: I used a richer ratio though. I can't remember exactly what the ratio is but I use a 20oz bottle full with a complete fill-up. I usually run until the Low Fuel Light comes on so it's about 25 gal. at each fill up. I'll let someone else do the conversion on ozs. to gals and figure out my ratio.
It does help smooth out and quiet down the engine/injectors. Mines beginning to lope or surge at idle again since it's cooling off and the 2-cycle helps it moderately so that's why I say it's time to start using it again.
BTW, 142K miles on stock injectors. No additional filters; just the regular factory ones. I have a CAT filter setup I want to put on whenever I finally get around to putting my lift pump on though.
