    The only down side of 87 is there might be a little more carbon buildup on rings and in exhaust ports. We no longer bother to get 89 unless we are in a very hot part of the year and then 89 seems to start better.

    Regular, period. You are in fact wasteing your money putting high test in 2 stroke equipment or any small engine. It may actually shorten the life of the stuff because of the higher operating temps. The only thing that you should put high test in is performance cars purely because the engines have been tuned to run different. And besides, it doesn't give ANY more power to small engines, just a hotter cumbustion.

    Idealtim Gut It Right. The Higher Octane Makes It Run Hotter. Unnecessary. (plus Its To F***** Expesive) $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

    Echo says RIGHT ON THE BOTTLE to use 89 octane. Don't you think they would know? "doesn't give ANY more power to small engines, just a hotter cumbustion" That is wrong. Higher octane = higher compression = more power. Of course there will be more heat with power but these engines are capable of it.The compression is so high in 2 stroke you are likely to get misfiring with 87, HENCE the recommendation of 89. I belive you also blow your warrenty if you use 87.
