I took a 350 mile trip a couple of days ago, and I noticed that here in Virginia all of the gasoline sold stated that it contained 10% alcohol.<p>I couldn't really notice any difference in performance. Even though our cars are not "flex cars" up to what percentage can our engines tolerate, and how will 10% alcohol affect our engine? Turbo, etc.?<br> <IMG NAME="icon" SRC="http://********************/smile/emcocktl.gif" BORDER="0"> <IMG NAME="icon" SRC="http://********************/smile/emcocktl.gif" BORDER="0">

Re: Alcohol Anyone? (matsharris)

From the online manual:<br><A HREF="http://apps.volvocars.us/ownersdocs/2005/2005_V50/05v50_07a.htm#pg103" TARGET="_blank">http://apps.volvocars.us/owner...pg103</A><p>Gasoline containing alcohol and ethers<br>Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must still be met.<br>Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as Ethyl alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE may be used.<p>

Re: Alcohol Anyone? (matsharris)

I read a magazine article last night that talked about the effects of corn ethanol. Tests were performed on a truck that can run either fuel. Ethanol octane was somewhere between 100-105. Ethanol is about 70% of the power of gasoline. In the tests, there were about 30% drop in MPG at various speeds but performance seems to remain the same. BTW, the gasoline used was 87 octane.

Re: Alcohol Anyone? (Oldman)

I recently had to put 15% ethanol 89 octane in my T5. (It was an Iowa gas station that didn't have anything better--I've always used premium.) My gas mileage was significantly worse and the check engine light came on. Dealer reset it no problem and said the computer had to retard ignition for a number of cycles--I forget the number but it corresponded to the distance home from Iowa.<br>

I have ben using Virgina 10% Ethanol 87 octane for some time (since the price increases) and see about 2-4 mpg less and no check engine problems. Also I heard it was a new law by Bush to force ethanol (10%) on everyone. In Virginia this law took effect last month. Many stations were closed for up to 24 hrs when the switch took place so the underground tanks could be purged.<p>If gas price would go back to a reasonable price I will go back to better octane but for now who has the money???

Re: (wpbear)

Yea that 5 bucks a week is 1 Starbucks!<p>So if you get 2-4mpg less have you actually calculated if you're even saving money??<p>I still put premium in my rabbit so maybe i'm out of touch (has a cam, and good compresion so seems to like it). I just can't see the benefit of running crappy gas.

I just can't see the benefit of running crappy gas. <p>I can't see the benefit of running more expensive gas. Yes if I am on the highway with 2 less MPG I save money. Now if your car is so picky the check engine light comes on, then I agree move up a grade, but since that is the first I heard of that problem then there are probably other factors with that specific car. <p>If everyone gives Exxon Mobile an extra $5 a week, then what will their profits be......

Re: (volvoNB)

yup, that was kind of my point, and if he loses up to 4 then they're LOSING money not saving it.<p>Sorry, not trying to be a jerk but I don't think you're saving very much (if anything), and you're not doing your car any favours either.

Re: (TFS)

I agree with all this and want to add that E85 is a really bad idea in our cars. They're not tuned for it. Maybe they can be, but they aren't.<p>The 10% stuff is different, that's just the MTBE replacement formula and isn't something you can avoid in most states. I have found my mileage is dropping since those "up to 10%" stickers appeared on the pumps here. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/mad.gif" BORDER="0"> <p>Tom.

Re: (matsharris)

E85 or the 10% version? The latter is clearly not a problem, the car is spec'd for up to 10%. E85, maybe. Steverino's report that the CEL was lit is a concern. I'd avoid it!<p>Tom.

Re: (tmtalpey)

Thanks, I meant the 10% version. To me is seem that is can't be great for the engine particularly if it lessens the gas mileage.
