In my area some gas stations advertise no ethanol in their gas. What is the difference if any with using 10% ethanol or non ethanol gas?
What I learned from a fuels class I took is that ethanol attracts water which is bad for everything. The water and ethanol is harder for smaller carbs like 2 strokes have to use, so they plug up or run really badly. Ethanol runs colder and has less power than gas so you will see a mileage decrease. And ethanol will eat up rubber over a long period of time if the fuel sysem isn't deignede for it, so look for leaks periodically if you do run it.
Around here we dont have a choice, they blend anywhere from 5% to 18% in our Cali gas depending on the gas company.
Personally I wouldn't run it if I could.
Maybe in modern vehicles, but my tbi gets 2 mpg better on straight gas.:roflmao:
Run it and stop worrying about it. People sensationalize the claims of it wrecking engines and causing poor economy for no reason whatsoever. Just FYI, unless you live on the west coast or a few midwestern states your fuel isn't 10% ethanol. Usually it's 3% to 8%. I've never seen over 10% in the south.
As for the stations advertising no ethanol, most likely they're BSing everyone and laughing all the way to the bank. You CAN get oxygenate-free fuel, but it's not legal for road use. Ethanol is just one of several additives used in reformulated fuels. Even running higher than 10%, it's not going to hurt your fuel system unless you drive an all original 1967 Plymouth. Reformulated fuels improve the air for EVERYONE, and are better for engines. I see no problems? Stop complaining. Would you rather use ethanol that supports industry in this country, or have reformulated fuels burning chemicals known to cause all manner of developmental disorders and health problems? (lead and MTBE come to mind) OR you could run straight gasoline that barely meets 87-octane spec. Buy PEMEX fuel if you want to know what that's like.
