I'm gonna try a tank, if performance suffers just go back to ethanol
I have and always will store all my vehicles with NON ethanol with sta bil as we are snowbirds
no matter what the octane rating
And NEVER...and I mean NEVER...run ethanol in your small engine (mowers pressure washers etc)
The one exception (except for storage) is my HD Electra Glide...a hi compression motor
it will tap and knock on anything except 93 octane
