I've been using it for two months in place of twostroke. Haven't noticedany mileage increase at all. Also there is no antigel properties to it so i've got to use a antigel also. it doesn't seem to quiet the motor like two stroke did. I think i'll go back to two stroke with stanadyne every 5-6th tank when i'm done with this quart.

 

Yah I tried some last fall before it got really cold here. About the same results as you, no MPG increase but really didn't get much of a chance to try it.

 

I was on the BITOG site today and noticed a thread regarding the CA40. It looks like some people over there have tried it and didn't seem too impressed. Most used it there gassers though.
