Thread: E85 vs E20 vs Gasohol 91

If your car could take any of those, which one would you use and why?

I used E20 in my 2011 Fiesta the other day for the first time and could tell no difference. It is cheaper @ 32 B/litre so will continue to use it. I am not sure I can run E85 in it though, any ideas?

I don't think so. It should say in the manual and/or inside the gas lid.

As far as I know the only one that takes that right now is the new 2012 Civic. Soon the Altis also.

Don't try it because that's 85% alcohol and I think you can mess up the car good if it can't take it.

If I had a petrol vehicle I would have it tuned to use E85, makes good horsepower.

I was wondering if E85 was worth it. It is cheap, but the fuel economy will be bad. I think it may give me a day and a half less fuel than gasohol 91. I think I could go a full 7 days on gasohol 91. E85 may get me 5. Not sure how much I will actually save.

Unless you are going to tune your car to to take advantage of the higher octane that E85 has then it's not really worth using it.

The 2012 Civic is built for E85. That's what they've been promoting

It all has to do with calorific content.

Work out the cost per km not simply that the car doesn't run any differently.

In Brazil with 1l car, one tank of petrol yielded almost 650 kms. One tank of alcohol only 450!

What do you mean by 'tune the car'
Doesn't the ecu automatically adjust the mixture and timing when it detects E85 ?

Intake/Exhaust mods/camshafts/aftermarket ECU/forced induction etc etc is "tuned".

That's funny

Anyway. Just read an article about a breakthrough on this lubricant for engines that run on E85 (in thailand) and the guy was saying how e85 engines should change the oil every 3,000 KM?

I don't know. Even the Civic is rated for E85, I'll stick with Gasohol 91. Gives me more fuel economy and I don't have to worry about it burning a hole through my car.
