This is the post I was referring to, weeks ago btw. Every credible source (including the EPA BTW) states that fuel economy with E10 is 3-4 percent less than with non ethanol gasoline, yet you say you have personally verified a 10% reduction many times. Please then share your scientific data demonstrating that. How did you control for all the other variables that effect fuel economy and what were the statistical techniques you used? Or perhaps this is just an personal anechdote you are putting forward? Again. With reference to Colt's post, if we bought fuel by the pound your units would be valid but we don't so we need to stick with units of energy/volume. So ethanol is 76330 btu/gal and gasoline is 116090 ⁶and the ratio is 65.8%. I do fully agree about avoiding using E10 in carbureted engines, especially small ones. If you have to, and in many places you do, then it's best to have a fuel cutoff valve and run the engine till it shuts off from lack of fuel before storage, which will (mostly) clear the carb. I'm not a big fan of E10 personally, especially because it screwed me up in the past for mogas aircraft use. 100LL avgas is extremely expensive and has lead in it which causes lots of other issues. E10 is harmful to expensive aircraft fuel system components. But E10 is better environmentally than the MBTE it replaced. As for it otherwise being food, that in itself doesn't bother me. Only a small fraction of corn produced in the US is consumed by humans, and that is mostly in the form of high fructose corn syrup, not really the best stuff for you. The fact that corn ethanol's energy balance (output energy/input energy) is so bad does bother me. There are much better biofuel feedstocks. Brazil, for example, which uses mostly sugarcane based ethanol, is much more efficient at ethanol production. |

LOL! Makes no difference how you buy a fuel, it burns based on weight/mass/mole.
You cannot also, honestly, expect a government agency with a vested interest in enforcing its edicts to publish accurate data. I spent most of my life in environmental engineering, reading the slanted, or "spun" research. It is done by selectively omitting data points so the conclusion reached is the conclusion desired. It was thus for over 30 years. So, yes, I also, typically get 10% worse mileage on E10. Now, one tank might calculate 8%, but the pumps all say "up to 10% ethanol". I'm told the ethanol is dropped into the tanker just before it leaves the terminal, a bit like an afterthought. Not an accuracy laden process. |

I found that most of my carb issues stopped when i started using Sta-Bil in my E10 gasoline.

10% worse by weight or by volume? ![]() Any engineer or scientist knows you have to get your units right to start with. Either mass or volume can work but you cannot switch back and forth in the middle of a calculation. If you want to do it in energy content per unit mass then stick with that for both fuels and for the mixture, then convert back to volume at the end because we don't buy fuel by the pound. As for "spun" research, there seems to be a need these days to believe in all sorts of conspiracies. All the government agencies, auto manufacturer tech staff, university automotive engineering departments are all wrong and something I read from some guy on Facebook is right. That includes many other countries where ethanol is added to fuel as well. Sure, and there are children captive in the basement of Comet Pizza too. There is no way a casual user can resolve the difference between 10% and 3-4% (about 6%-7% delta) in fuel consumption in their day to day driving. Way too many uncontrolled variables to resolve a small difference like that. I know, I've had to try to evaluate small efficiency differences like before and it's not easy. So when someone can present statistically controlled peer reviewed data demonstrating that then I'll listen otherwise it's just anechdotal statements. And yes I do expect my government and science and engineering community to publish accurate data and I do not expect some random guy on Facebook or YouTube to. |

I found a 4650 watt inverter generator by Champion with remote start and it works perfectly. It will run everything I need, including the a/c. I have a hard time finding ethanol free gas in my area ( Northern Illinois ) so add seafoam to all my fuels, and i do use the premium blend in my unit. Thank you all for all the iformation!

I know this has probably been beat to death but I am looking at a Firman 2900/3200 generator invertor. It seems like this would run the AC on my 189. It is listed at $699 seems pretty reasonable. A little heavy at 94 lbs but if it runs my AC I'd be happy

It will probably start the a/c without an Easystart. Might be close though if it's overload protection circuit is fussy. If it won't start it then you can return it or put in an Easystart.
Your back might not survive though. Your alternative is an Easystart and a sub 50 lb 1-ish kw generator. The Easystart is well worth not having to have back surgery IMHO. |

I purchased a used honda on e-bay from a pawn shop gently used for 600.00 works great very quiet

Since I converted my two Honda EU2000i generators to propane operation, I'll probably have to use both of them in parallel to run the AC even with an EasyStart now unless I want to mess with gasoline again (which I don't). I wanted to get away from gasoline due to the mess and smell. Propane tanks are clean enough that they can ride in the passenger compartment of my SUV.

I have someone local that has a Craftsman that was 3000/3400 watt that was used. New was 899 he wanted $800 or best offer said it was only used once?......the Firman is $699 new with warranty. Seems less risky to me if it will run the AC. Several reviews indicated people were running RV ACs with it and no issues.
