Default Fuel with Ethanol?

Hi,

I was ondering if anyone has had experience, positive or negative, with ethanol enriched fuel. In Canada, I can buy fuel from Mohawk which is ethanol enriched and rated 92 Octane. However, I worry that the alcolhol will cause it to burn hotter, and may distort the heads or something. Or cause injector fouling. Anyway, I'd like to know if anyone has an opinion on it.

Thanks in advance,

\m/

Just use some Jack Daniels at each fill up.

There are lots of xylene and toulene threads in 2.0L turbo, so a search will get you up to speed on those two types of additives (which are used by a lot of members on this board).

Ethanol is listed as an alternative fuel for different engines (aka 'corn' engines). He wouldn't put that in his old gas burnin' vehicle.


Full_Clip thinks you should check your manual.

What?! When there are all these great people willing to help? You are of course right, I only thought of it this morning and now I'm at work with the manual far away at home. According to the promo about enthanol additive, it should simply burn cleaner, but I wondered if there was a down side. I will check out the toluene threads. Thanks for the tip.

In the US, Sunoco and Mobil routinely use ethanol as a gasoline additive. We're talking like 10..15%. I don't hear anyone complain that Mobil 93 octane requires different tuning than, let's say, Shell 93 octane...

Here in NY for the past 6 months, we've had 10% ethanol fuel due to the law banning MTBE as an additive. Our cars are running fine. The manual specifies that this type of fuel is ok.

The only hitch with 10-15% ethanol fuel is that ethanol has lower energy per volume than the gasoline it replaces (I'd have to go look at the high school chemistry books to calculate exactly how big the difference is). It does, however, have a higher flash point, and thus will raise the "octane" rating of fuel.

The million dollar question, however, is whether we gain more power from being able to advance the timing further with high 92 "octane" fuel, or the higher energy in regular 91.

I know that my gas mileage is better when I use regular 91.... but given different conditions for each tank, it's hard to be rigorous about this.

Scott.

I don't like gasahol as it is corrosive to some fuel system parts.
