First off, it is E85 that I mix with 94 octane. Funny thing about octane ratings is that it can work both ways, and still detonate, and preignite in certain engines. Ethanol is a very oily fuel, it does not evaporate like METHANOL. When E85 evaporates, it leaves behind an oliy residue, Methanol, evaporates compltely, and it does leave behind a corrosive residue, almost like an acid. it is like a whitish substance, and yes it will eat parts. E85 on the other hand, does not do this at all, it will leave a residue that is more like oil, than acid. There is a difference in the chemicals used to make ethanol, than Methanol. You have to run an upper cyl lubricant while burning Methanol, it is just too dry of fuel due to the evaporation rate when mixed with air. Methanol, you will use twice as much, due to the evaporation factors, it does atomize at 4-5 times the rate that gas does, therefore, the molecules will be alot smaller VS a gasoline based fuel. Ethanol, when mixed 50-50 with 94 octane, can and will fire an engine perfectly at 300 psi, no detonation, or preignition. I know it can, I use it all the time with 300 psi engines! As far as the octane ratings are concerned,,, ethanol, is a good substitute for octane boosters because it has a lower flash point to create ignition. Which is the same thing that octane does, it makes the fuel harder to ignite under more pressure. There is a differnce between Methanol, and ethanol. Methanol is the fuel that will do damage if not set up properly, it will lean out, and burn up parts. That is the leading misconception of what the terms of alcohol fuels. There is more than one type of it, and the factors created by each individual fuel is different, one is oily, one is not. Which one will do damage? I figured, when I mix 50-50, every gallon of ethanol mixed with 2 gallons of 94, will increase octane 4-5 points depending on how good the 94 fuel is. From what I read on the pumps at the gas stations in this area, 10% added to 87, makes 89 octane. The 87 fuel dont change the octane, the ethanol does. Hope this makes sence, I have it wrote down somewhere as to what the exact octane was when mixed at different levels. This is just off from what I remember from the formula we came up with without looking. Ill make you a bet though,,, Ill put my fuel up against any fuel out there, and it will make more power, run better, than any 7 dollar a gallon race gas! any takers? Not trying to be cocky here, please dont think that,, Ive had alot of tractors in here with a wide spread of fuel selections, and nothing, and I mean nothing equaled the cost, and the HP output than E85 and 94.
