Hi captain, I am using Arco's 87 octane and methanol I don't know if the composition of gas up in michigan woul be the same as here in california I guess is not, but try just your regular 87 octane gas ans see how it works with you just make sure to use an oil that will mix with both gasoline and methanol (Klotz works very good or try as I do 50/50 amsoil other good synthetic and castor oil) and if you can get ahold of sime nitromethane try it at 5%
