I still cant decide whether or not if non oxy gas is better to run instead of regular 87. Since all of the non oxy gas around me is high test I believe it may be worse on the engine since carbon buildup with the higher test is greater. I almost think the carbon issue may be a bigger concern than ethanol considering I am running an additive to take care of it. I spend a lot of time on Lake Minnetonka which has a 40 mph and a lot of channels to idle through.Look forward to everyones thoughts on this one.
