Ethanol free fuel?

[DoubleEagle]

I don't think I have filled up at a station in years that didn't oxygenate the fuel..

How can you tell your fuel is Oxygenated ? Is it the fact that it doesn't say E10 ?  Dolph

ethanol is what is used to oxygenate gasoline.

ethanol, like all alcohols, absorbs moisture. 

moisture + engine = not good.

yeah but if you put alcohol on your rubber it will suck up the moisture in them, deteriorating them right? so your fuel lines are in danger with E10.

that is a problem with an older vehicle, but newer vehicles use Nitrile and EPDM for fuel lines which is impervious to ethanol. 

the main issue with moisture and ethanol is how it wicks moisture from the air so you are always adding water to your gas tank when filling up with E10 -- how much is debatable.  if you live in a low-humidity environment or during winter, it is probably negligible, but if you live in high humidity and during summer, better use that gas fast.

you can add things like StaBil to offset some of the separation problems, but it is just an inherent problem with alcohol in gasoline.

i guess that's why they say that ethanol is bad for any vehicle/engine that isn't used regularly. ie your mower or your bike that isn't used daily.

They mandated labeling pumps here in Oklahoma in July.  Before then I was using E10 without knowing it.  Before the labeling, E10 and regular gas were the same price... now regular stations are about 10 cents a gallon more.  hmmmm   So anyways I've been using this luxury of knowing wtf I'm putting in my tank - I can tell a difference with my bikes and a big difference with my 2T lawnmower.  My truck ... well I can't tell any difference including mileage.   It kind of looks like the smaller the motor, the bigger the difference.  A friend's MV was running hot - Ferracci told him to run 100% gas, that ethanol made it run lean and hot - so he switched and now the bike runs cooler and he gets better mileage too.  BTW regular e10 is $2.49/gal here in OKC today.

you will notice a difference if you have a well-tuned engine. 

my 900ss engine was balanced and blueprinted -- very noticeable difference when i put in 100% gas. 

gasoline has more energy than ethanol, so more hp.  period.  there really is no comparison.

plus, you'll get better mileage.

I'll definitely second that last line.  I typically loose 4-5mpg in my car over a tank with the commonly available ethenol blend.  I don't think anything I have is tuned enough to *really* notice the performance aspect.  Now my fiancée has a Flex-Fuel GM vehicle, and get 26-28mpg on the 10% blend ~

The FlexFuel vehicles are a shame.  They reportedly get about 10-15% worse mileage with E85 vs E10.

Stripes are usually 100% gas

Yea, but the make the E85 per gallon mileage decent, it pushed the per gallon mileage way up on straight up 87.  Mixed drive on a '08 Impala w/ a 3.5L V6 on pure 87 unleaded is 27-28.  Highway is above 30.  Good for a larger heavy sedan ~

Has anyone rejetted a carb to run on alcohol? For the engine to run right jetting needs to be almost doubled. That's why an engine will run hot/lean/get worse milage with alcohol in the fuel. Almost twice as much is needed for a proper burn compared to petrol. E85 still has 15% petrol or else the milage would be completely in the basement.
