E85 is 85% ethanol. I hate the stuff. It eats at the seals in my trailer. Ive never had to replace seals as much as i have in the last few years of hauling the stuff.
As we speak, im delivering Mid-grade, non-ethanol fuel to a station. 87.3 octaine. Now my Bill of Laiding calls it Prem. Non-e. And some places sell it as Premium because of this. Plus the fact that if you add the Ethanol to it at 10%, it brings it up to 91 octaine. This is Premium fuel at Colorado elevation.
I bet most of you know Premium to be 93 octaine. But thats because of the lower elevation and more CO2. This Non-oxy 87.3 octain fuel sells for the same cost as Diesel fuel and we all know Diesel cost more than Premium. Im my personnal studies and testing of fuels (gasoline) ive found that burning the Regular fuel is cheaper in the long run. Yes, you dont get as many miles per tankful, but the cost at 10 cents or more a gallon difference doesn't add up the the extra miles you get. Now, if you take the cost of engine repairs into this, i find the issue is the Ethanol and not the lower octaine fuel.
In the fuel tanks at all fuel stations that have ethanol in the fuel, you will very seldom find water. The reason is the ethanol suspends the water in the fuel and keeps the water mixed with the fuel and ethanol. So that when you get it in your vehicle, its a very little amount, and the ethanol counters what can happen if you put water in the tank. So besides the goverment getting kickbacks or whatever for us burning ethanol in our vehicles, it also hides the fact that... ALL GAS HAS WATER IF ITS BEEN IN A TANK! They wont stop condinsation in a tank unless its left full. And that aint happening.
So take this bit of info and believe it or not. Its just my opinion. Its possible i might have played with a little bit more fuel than some of ya. Lol.
