E85 fuel for our truck - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jetmech727 · 01-15-2006, 08:08 AM

Has anyone else put E85 in one our trucks? I tried it yesterday and I could not tell the differance. I had about 5 gallon of gas in the tank when I pumped it in. What is your take on using E85. They just put a pump in close to the house and I'm probably going to try running it as often as possible.

Good reading on E85

I wouldn't run much e85 in your engine unless everything the fuel touches is made of stainless steel. That fuel will corode your gas tank and fuel lines quickly. The only thing that makes any vehicle e85 compatible is the stainless steel.....

Alcohol eats carburetors.

And fuel lines and tanks.

Two of the guys at work have tahoes that are E85 compatable (I think one is an '03 and the other an '04). Both have tried the fuel and quit using it. It's not much cheaper than gas (at least around here it's only about 10 cents per gallon cheaper) and both guys noticed a 1.5 to 2 mile per gallon loss for both city and hwy driving. That's 30-40 miles per tank. They figured with the mileage loss, regular 87 gas was cheaper.

Ethanol shares biodiesel's emissions advantage because it is "carbon neutral".

When you burn Ethanol or Biodiesel you are releasing the carbon which the plant absorbed over it's lifetime back into the atmosphere as CO2. Thus, there is no net increase in CO2 levels - the plants take it out, and your engine puts it back.

With Petroleum based fuels ("Dino" Diesel, Gasoline), you are releasing CO2 into the atmosphere which was absorbed by plants millions of years ago. Thus, we are all reintroducing tons and tons of CO2 back into "circulation", so there is a huge net increase of it in the atmosphere.

Essentially, the argument is that if everyone used Ethanol or Biodiesel, there would be no global warming, because CO2 levels would be unchanged.

Or at least that's my understanding of the situation.

However, take all of that with a grain of salt. I am almost certain that all of the farm equipment used to grow the corn for the ethanol (or soy for biodiesel), and the machinery used to process it are using fuel and electricity derrived from fossil fuels. If the entire process were completely "green", it would be much more expensive than it is now because the yeilds would be so much smaller (you'd have to burn a lot (but not all) of the ethanol or biodiesel from last year's crop to plant, harvest, and process the current crop).

Methanol eats aluminium ethanol is not harmful to aluminum.
