Frank, if it is only 10% you will not notice much change at all. We've had it here for many years already.
You may have to jet up a hair, other than that you won't see much happen.

| Post subject: | GAS VS Gasahol |
Well Folks THE SOUTH has finally moved into the age of gasahol. The last 6 months we have started seeing the 10% Ethanol stickers popping up on all the pumps. Now it appears that a few select business/brands and the Track are the only place we can get 100% gas. My Questions are how will this affect Cindas race car She runs 94 oct. And how will this affect our cars generally. Thanks, Frank |

I sure notice it in the extra cold weather with no choke and no heat crossover on the van. Like this morning @ 16* |

I lose 2-3 mpg on the winter blend. I don't expect that's entirely due to the alcohol content, but something is different starting around Nov. 1 |

I took Dan's advice and went to the fuel injection hose. My lines were going soft in no time and I kept getting debris in the carb. We have had ethanol in our gas for about 6 years now. It takes a little more tuning and maintenance to keep the mileage up. Summer gas definitely provides better mileage. |

I mentioned this in the social section; basically, the ethanol blend ate my weedeater and chainsaw up. Had to replace the fuel lines. And now that I've moved, we have it here too.  I guess we have to live with it. |

The stoichiometric point for gasoline is 14.64. 10% ETOH gives 14.06. So you would have to jet up about 4%. Also, the wall wtting characteristics for gasahol is a little different. Mitch |

Coconuteater64 This explains alot!!! I have had several small engine failures this way ALL with Eth blends. Any way to prevent it? Will stableizor keep it from happening? Sorry this is getting off track. Thanks for the jetting idea Ill watch my plugs. Frank |

I'm sure there are some alcohol safe fuel lines. We just don't have any around here that I have found. After using E10 for a couple of seasons, my fuel line crumbled like a cracker. Never in my life have I seen rubber rot so fast! |

If your fuel line hose is ¼" ID or larger, you can just use automotive fuel injection hose (marked "30R9"). Small-engine fuel line smaller than ¼" ID is something of a problem, but Tygon F4040A should stand up to any alcohol content you'd find in pump gas. Be sure you're actually getting the genuine stuff; there's a lot of lookalike (but not workalike) junk on the market. A giant Federal study was done of the effects of ethanol-blended gasoline in cars and small engines. They didn't test cars older than 2001 or so, but the highlights of the findings with newer vehicles are pretty revealing: Significant loss in fuel economy, no effect on regulated emissions, increased formaldehyde emissions (yum yum!). Small engines ran progressively hotter and less well with increasing ethanol concentration in the fuel. They didn't see any driveability problems in cars because they didn't look; they do note no "cold" starting problems when tried as "low" as 50°F. I haven't read the whole study yet, but what I've read so far looks disturbingly like the conclusion (hooray for ethanol, let's add more of it to our gasoline!) was prescribed before the "study" was carried out.  That's disappointing, but given the large and very successful ethanol lobby, it doesn't surprise me.

Dan Thanks again for your vast knowledge of the Automotive World. You never cease to amaze me. Frank |

Dan, With minimum of 10% ethanol or so it says on the pump sticker, how much mileage loss should we expect to see? A 1/2 mpg or 1 mpg? or more? |
