wrote: Only ethanol-blended gasoline has been available at New England service stations over the past several years. Not correct. New Hampshire sold auto fuel (in the southern counties only) with MBTE until fairly recently. The swtich to alky was no more than six months ago. In the northern counties (Carroll being the one closest to me, a drive of about thirty miles) MBTE wasn't required, and I knew more than one car owner who made the trip weekly because he didn't like the notion of MBTE (or is it MTBE, crikey, I don't know). I'm uncertain whether the ethanol mandate applies there or not; I don't think it does, since ethanol was introduced only as a substitute for MBTE.

wrote: Profit margins vary a lot by company and over time, but a mid-term (not long term) average of ~8% seems a useful number.[2] Though Exxon managed to get nearly 11% last year.[3] Exxon had a good year in part because it owns a lot of refineries. In the past, refineries have been a very bad business (the money was all in extracting oil from the ground) but lately there's been a huge shortgage of capacity (hurricane Katrina, Europe no longer exporting much gasoline) so refineries are stretched to the limit. When something is stretched, the price goes up, which is why Exxon did better last year than say Royal Dutch Shell or Beyond Petroleum. (For years, we have been importing gasoline from Europe. Isn't that a hoot? They've historically tended to need more diesel than the refineries could easily produce without exporting the lighter stuff, and the excess came to us so the yuppies didn't have to have a bad ole refinery in their backyard.)

You know I've been wondering: Does the Alka Seltzer trick really check to
see if alcohol is present? I'm no chemist, but I wonder if the Alka Seltzer is just reacting with the water that most alcohols will attract from the moisture in the air. How about it? Any chemists in the group? If the mogas were blended with alcohol with low water content, would the Alka Seltzer fizz at all? Maybe the best test is still the "line on the beaker" test. Well, we've been down this road before, back when the Alky test first came on the scene. Some chemist here ended up concluding that the test was valid, but I'm always open to hearing other thoughts on the matter. If the danged test DIDN'T work, that could ruin my whole day... -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

You talking about "rubbing alcohol"? We tested it with that, and it
worked for us. Fizzing, that is... nope -- "Denatured Alcohol" purchased in a gallon can. What's the difference? Is one ethanol, and one methanol? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

"Cubdriver" wrote I bought four gallons two months ago and haven't used it all yet. It's astonishing how far gasoline goes in small engines. (Well, okay, I don't mow my lawn any more. The clean mogas goes into the chain saw, generator, and snow blower I'll bet it really lasts a loooong time in your snow blower, this time of year! ggg -- Jim in NC |

"Cubdriver" wrote Mogas at Hampton Airfield NH is still $3.40, though I suppose it will go up in time, especially if lots of people discover they can buy unadulterated gas there. It depends on management's philosophy. If they were to keep their profit margin low, and sell a lot of it, they might find it is better to keep it cheap to sell a large quantity of it. Of course, it all hinges on being able to keep the supply coming fast enough. -- Jim in NC |

I read that, starting in 2007, in some places, California and some Canadian Provinces included, it is regulated that all gasoline sold must contain at least 5% alcohol/ethanol. Tony Here in Ontario I was told not all gasoline must have 5% alky, but 5% of all fuel sold must be alky - so 50% of all fuel sold being E10 satisfies the requirement. In practice, virtually all 87 octane will be e10. Premium 91 will (from some companies, at least) be E0, making the blended 89 E5. Since significantly over half the gasoline sold in Ontario is 87 octane, this would excede the requirements. - Just from what I've been told, but you can never trust the elected idiots, or worse yet the beurocrats IF I ever get a plane, all these silly fuel issues would be a real irritant. I haven't been paying much attention to the new diesel aircraft engines becoming available. Since I should be making my own biodiesel by the end of this Summer (for something less than 45 cents a gallon), are any of the new diesels in the O-200/Rotax 912 class? What do you grow to make biodiesel? Relatives that own restuarants and have to pay to dispose of waste fryer oil! You grow relatives? Well, somebody planted the seed and they tend to grow on their own. I just fertilize them now and then! What do you actually do to the waste fryer oil to make it useful as biodiesel? A common misconception is that biodiesel is just filtered vegetable oil; this is not the case. Straight Vegetable Oil (SVO) (and Waste Vegetable Oil (WVO), for that matter) don't have the proper viscosity to run in a diesel engine unless they are heated to the 140 F to 170 F range. More importantly, they solidify at too high a temperature and will clog the injector pump and injectors. Biodiesel is vegetable oil that has gone through the transesterification process. Simplified, you mix many parts vegetable oil with one part methanol and a little bit of lye, then heat and stir the mixture. After a while, you have a tank of cloudy oil with glycerine on the bottom. You then bubble air through the oil until it is no longer cloudy, and the clear oil is biodiesel. |
