Can i run ethanol in my 1993 buick lesabre - it has multi port fuel injection?

Question

If i run a still and make 180 proof ethanol can i run that in my old computer controlled fuel injected buick lesabre? i wonder?

Answer 1

It will corrode your fuel system very quickly.. Ethanol gets fewer mpg than straight gasoline anyway, --moot point--get a diesel -powered car and enjoy the benefits of several fuels

Answer 2

Not unless your 1993 Buick is a flex fuel car. I think the changes are minor to make an engine run on ethanol, having to do with ensuring the metal and rubber and other materials are not dissolved or corroded by ethanol and engine control changes like a different fuel injection volume and spark timing. But if any of these changes have not been made, ethanol can ruin your engine. The owner's manual will tell you what kind of fuel is safe in your engine.

Answer 3

Its is not yet feasible to run automobiles on ethanol.

More research needed.

Answer 4

sure your mechanic will love you

all the pennies you save will be needed later for a new motor or fuel system or both

Answer 5

You will only be able to run (without modifications) 20% ethanol...all vehicles made after 1988 were required to be able to burn 20% ethanol...although most experience problems with a mix that stout.

In order to burn 180 proof (90% by volume) you would need to replace ALL rubber components in your ENTIRE fuel system with neoprene and advance the spark timing and change plug gap...ethanol burns slower and is harder to ignite...you may also have to replace othwer gaskets (intake, injector o-rings..etc)

IMHO ethanol is not the answer...biodiesel for diesels is great; but, bio-butanol would be a much better choice for gas powered vehicles. ethanol just has too many deficiencies...poor mileage, absorbs water..etc

Answer 6

As long as you run less than 30% ethanol in it overall you'll be fine.  If your alcohol is 180 proof though, what is the other 10%?  Water?  If it's water you can't do it.  I have been running E85 in my non flex fuel Ford Focus for 3 years now with zero problems.  It runs fine on it.  I use the "start low and go slow" approach.  Put 6 or 7 gallons of gasoline in it and then add 1-2 gallons of E85.  That will put you around 15% overall.  Each time you fill up, increase your ethanol % by about 5%.  If you cross 50% ethanol overall in your tank, the check engine light will come on but the car will continue to run normally.  My check engine light stays on when I am over 50% ethanol in my Focus, which is all the time.  But there's no difference in the performance of the car, other than it accelerates way better on E85.

Answer 7

All you have to do is look in your vehical manuel it will say what you can and cannot burn. Or like most look on your dash board.

Mine says regular only.
