Stihl power equipment and ethanol "enhanced" gasTook my Stihl blower and weed eater to my local Stihl dealer since both seemed to die at the same time.
Got a call from him just a few minutes ago. He finished up repairing the weed eater and is starting on the blower.
Bottom line is the carburator was destroyed by ethanol and had to be replaced. He cleaned the muffler screen and installed a new spark plug and says it runs like a swiss watch. He indicated that probably was the problem with the blower.
He said he see's this all the time. Now I put this same gas in my vehicles. What's it doing to them? I might put it in my vehicles if it's not too costly. A benefit will by more power and better gas mileage.
In the past couple of years many vehicles have been damaged in Hampton Roads from excessive (>10%) Ethanol in the gas. Poor quality control I guess but the damage is done.
Now for the good news. My local quick stop is in the process of replacing their tanks. Talking to the owner today who was wiring up the new pumps A new addition will be non-highway diesel and "ETHANOL FREE GASOLINE" for boats, tractors and other power equipment. This is great news as the closest source for non-ethanol is marinas and a station 25 miles away. |

Ethanol will absorb water out of the air. In teh carb the gas evaporates away leaving the water that then corrodes the internals. The carb repair kits now come with a different set of gaskets and diaphragms that don't get stiff with ethanol. Once I saw pumps with "up to 15% ethanol" appear in my area, the next few months every neighbor stopped by with riding mowers, blowers and push mowers with crapped out carbs. That is when I started actually seeing algae growing in carbs. Also saw gas tanks with grey slime suspended in the gas. There is also the issue of ethanol is a different solvent. Once it get introduced in an old system, it dissolves lots of crap in the tanks and lines. I'd say less than 10% seems to not cause much problems. I seem to recall the main small engine manufactures filed a petition gov agencies to ban more than 10% ethanol as higher concentrations cause so many problems. The other issue, is engines need to run richer on ethanol fuel. (Ethanol at 19% vs gas at 14%.) Cars will adjust for it. Small engines are already run lean to meat EPA restrictions (too lean IMO). Too much ethanol and they start backfiring, breaking rings and burning valves as they are too lean. With the shortage of corn, looks like they will not be adding much ethanol for a while |

Will you press him please on how to minimize the impact of this--there must be an additive we can use if there's no ethanol-free available? I bought a new Stihl FS90 trimmer this year and a stash of Stihl oil to use with it. A really good dealer I think, but they didn't mention anything to me about fuel problems... How old are yours? I bought the warranty extension for mine taking it to 3 years I think. |

I was considering purchasing a gasoline powered generator. I was advised by a customer service representative at Lowes that I should use ethanol free gasoline to fuel the generator and where to get it. We have a lot of antique car collectors in this area. Ethanol is corrosive to the fuel systems of vehicles that are not designed to use ethanol. A local petroleum distributor sells ethanol free gasoline for use by antique car collectors. I recommend that those that need to store gasoline for extended periods to check with local petroleum distributors to find one that sells gasoline without ethanol. I was assured by the petroleum distributor that by adding fuel stabilizer to ethanol free gasoline I could store it for up to a year without deterioration. Unleaded ethanol free gasoline is more expensive than regular unleaded with ethanol. This same distributor also sells off road ethanol free gasoline which is less expensive because it does not include highway use tax. |

The bloweer is about 5 years old and the trimmer around 3. Never had any problems until now. |

That water will also freeze in winterThe carb repair kits now come with a different set of gaskets and diaphragms that don't get stiff with ethanol. My Stihls aren't that old and should have ethanol resistant parts. Evidently not. Once I saw pumps with "up to 15% ethanol" appear in my area, the next few months every neighbor stopped by with riding mowers, blowers and push mowers with crapped out carbs. That is when I started actually seeing algae growing in carbs. Also saw gas tanks with grey slime suspended in the gas. They saved the crap/gunk for me to see There is also the issue of ethanol is a different solvent. Once it get introduced in an old system, it dissolves lots of crap in the tanks and lines.
I'd say less than 10% seems to not cause much problems. I seem to recall the main small engine manufactures filed a petition gov agencies to ban more than 10% ethanol as higher concentrations cause so many problems. In my area apparently they can't keep the percentage at 10% or less.The other issue, is engines need to run richer on ethanol fuel. (Ethanol at 19% vs gas at 14%.) Cars will adjust for it. Small engines are already run lean to meat EPA restrictions (too lean IMO). Too much ethanol and they start backfiring, breaking rings and burning valves as they are too lean. I'm hoping for better performance with the ethanol free gasWith the shortage of corn, looks like they will not be adding much ethanol for a while The farmers petitioned the government to drop the ethanol percentage in gas to ease the price of feed. The Obama administration flatly refused. (so far) |

I was just thinking about this the other day when a JD walk behind quit. If you look at the pump, it gives the impression it's only the lower octane that has ethanol. I was thinking of starting to buy the good stuff. |

Here in Iowa we have 87 octane gas, and 89 octane gas with 10% ethanol in it. I generally pay a few cents more for the 87, and my cars and small engines seem to like it better. I was getting about 10% better mpg in a 2000 Blazer using the non-ethanol. |

I run Sta-Bil in all my small engines, particularly my chainsaw. Was told by a few dealers to run a higher percentage of sta-bil than they recommend, and this guards against water absorption. Has worked for me for 3yrs now.. Also keeps fuel 'good' longer. » www.goldeagle.com/brands ··· cts.aspx-j |

Is there a reason to add stabilizer to non-ethanol gas used in a golf cart? |

Kinda curious we're he is getting this ethanol free gas at, far as I was aware it was a federal requirement to have it in the fuel from the shipper.
Unless somethings changed in the last 7 years, I've been out of the industry that long. |

here's a site that shows ethanol free fuel » pure-gas.org/index.jsp |

That's why he's putting in a special tank and pump for the ethanol free. I can buy ethanol free at a station about 25 miles from me. Can't wait till my station finishes up and on line. |

There is no ethanol free gas in the entire state here. Ethanol is mandated to be in the gas by state law. |

It's required here also for motor vehicle fuel but it can be sold for off road, boats, power equipment, tractors, combines etc. Nothing says you can't buy it in gas cans and put it in your vehicle. Same with diesel. Off road can be sold. If it's not too expensive that's what I'll use in my 2003 Trailblazer. I'm not sure about my 1999 S-10. |

I use pure gas from Esso here, and my vehicles, and tools run far better, and cooler as well. More power, and fuel economy as well. With ethanol blend (10%), my vehicle has an unsteady idle, and with pure gas, smooth as silk. |

They use to sell pure gas at the airport stations but they stopped that a while ago. I wish I could find pure gas just for the yard machines. |

Go to a marina, or farm gas station for marked gas. |

Might be worth it Jack, after you see the repair bills on those tools. |

Precisely my point. How many gallons will it take to pay for the bill? I'll bet a few years worth, and no downtime either.
I also run full synthetic oil in all my tools, 2 and 4 stroke. Worth every penny, IMO. |

I hope you really don't think I care about that? Not hardly. I had no say about the forcing of putting ethanol in gasoline by the government to buy the votes of corn farmers. The hundreds of vehicles I see here with "Farm Use" tags, "Watermen" tags, "Antique Vehicle" tags are being used illegally. I say if they can get away with it have at it. |
