Engine Damage Caused By Ethanol Gasoline!?

[k0ua]

In most of the USA, premium has ethanol too.

then why do most of the pumps in my part of the world are marked "no Ethanol" on the premium button? And there are a few stations in Ar. that are marked "No Ethanol" on the 87 octane fuel also. But they are rare. Are they lying to us about the lack of ethanol in the premium?

Because Branson, MO is not "most of the USA". All of the pumps here in WV, eastern KY and Western VA are marked as being possibly drunk up to 10%. Sometimes the gas is not drunk, but its rare here. Count your lucky stars that you can avoid the rip-off.

Same here. I have to drive 35 miles to get the "Good Gas". 90 octane

Our premium is 91 everywhere around here.

Ours is 93 here

Murph, the thing about octane ratings as offered in different USA locations, that the higher your local altitude, the lower the listed octane ratings will be. Ohio should be, in general, about the same as sea level to 1k feet.

My point is we have a varying octane levels for non ethanol gas here not just high test.

I see tennessee has 93 octane also.Ethanol-free gas stations in the U.S. and Canada

Colorado has 112 Wow!!!!!Ethanol-free gas stations in the U.S. and Canada

Ethanol actually is an excellent fuel. The problems that are described above are from people putting it in engines that are not compatible with it. You don't complain that your chainsaw is ruined when you put diesel fuel or kerosene in the tank, why would you expect ethanol to do anything different?

There is one big, huge advantage to ethanol that nobody ever seems to talk about, which is that pure ethanol's octane rating is 100 for NA engines and estimated to be more like 115 for forced aspiration applications. This high octane is why just 10% of it increases the octane of gasoline 2-2.5 points and one reason why most gasoline has ethanol in it (most places do not have an ethanol mandate.) Burning E85 which has an octane right around 100 in a typical flex-fuel engine that can also run on 87 octane swill doesn't do the fuel justice. Ethanol would have a much better rep if higher blends like E30 (about 94-95 octane) or E85 became widespread enough that engines were actually designed to use that fuel.

I'm with Walt. We have wildfire suppression equipment both 4 stroke honda and brigs pumps and 2 stroke stihl brush saws, backpack leaf blowers and chainsaws. They receive a lot of long operation abuse for short periods of the year. They may sit on a shelf for 8 months along with the fuel. No issues for 12 years.

Around here all the fire pump gas is clear non ethanol premium, saw gas and Mark 3 gas is clear mixed, no ethanol.

The road diesel is going to B20 but the state is forgiving the state tax to sell the biodiesel otherwise it is too much and the off road and PUC diesel is B5 because the loggers will not put up with the crap.
