  1. Jubilee in Ishpeming Michigan no longer sells E85, they have a big sign that says ethanol free unleaded. This leaves Sault St Marie as the only E85 station in the entire upper peninsula.

    $1.10/gallon at Michigan Speedway stores!!

    Seriously? I have even more incentive to get my stills back in operation. When I do you can bet your butt I will be showing anyone who wants to know how to make their car run on it and how to make it. I bought my last ten gallons from those crooks in Ishpeming.
  3. Still a five cent spread in the UP at the only pump left.

    Incredible spread in Ishpeming Mi.

    The Soo does me no good, thats a three hour one way drive. They have the only other station that carries E85. Too far to go for fuel. Marquette is getting a tribal station, they are building it now across from Lowes next to WalMart. Caused a big stink when they decided to do it, because the local guys cant keep the price up around California prices.

    He said they all get fuel from the same supplier in Green Bay, every station gets it from the same place. Everyone here knows that you drive north to Houghton fifty miles and gas is 30 cents or more cheaper. They are gouging Marquette and nobody cares. We almost always have the highest gas prices in the state, far too often the highest in the midwest. They arent going to get a different supplier. I asked the new tribal station owners if they would put E85 in and they said hell no, because it ruins cars. If the land here wasnt so cheap I would move.
  6. It was a whopping 5 cents today. 87 $3.57 E85 $3.52 Asked why the poor spread, guy working there told me its because they are paying $4.20 off the truck, that Green Bay is gouging us. He said the owner is considering getting rid of E85 because he has had problems with people claiming it harmed their vehicles, and it isnt selling. Well with no spread to speak of it will only go in vehicles that run nothing else. Its hard to read in my pic, but its $3.57. All the gas around here is that high, 92 is $4.07 at the Holiday station. I see sub $3 gas and under $2 E85 posted here and I want to move.

    Isobutanol - the next gen biofuel

    Looked into this a while back. While it takes 10 gallons of water to produce one gallon of ethanol, using bakers yeast and a few gallons less using a hardier strain of yeast, you can reuse the water as is, or release it back to the environment without issue. Isobutanol uses 100 gallons to produce one gallon of fuel, leaves the water toxic and it must be treated before being used for fuel production or released back to the environment. Its made with bacteria and they are far more sensitive to living in their own waste than yeast. The toxicity of the fuel is also an issue, because spills would be hazardous just like gasoline. Im not sure how easy it is to put out a fire fed by isobutanol, but ethanol takes simple water while gasoline takes foam. That isobutanol doesnt absorb water means rusted fuel tanks and water in fuel system problems just like gasoline, ethanol absorbs water but allows you to burn it. it mixes readily and causes no harm to anything until you get over 35% water in the fuel, and then it is only untreated/non anodized soft aluminum. Im not sure of its corrosive properties, so that might be a non issue. The food vs fuel is useless since most of the feedstocks we can use for ethanol production are not food for humans. Kudzu, cattails, and other weeds grow profusely and yield far more ethanol than corn does. The water issue is of bigger concern with butanol because it requires so much more and requires treatment before reuse or release. Sure we can make it, but at a cost of drinking water and more expense due to treatment after producing butanol. Having a far lower octane means less power potential, less efficiency, and needing larger engines due to lower compression ratios. I didnt look into its latent heat of vaporization characteristics but I doubt it will be as efficient as ethanol at cooling the intake charge. Sure butanol is higher than gasoline, but that isnt saying much. How does it run under boost and heavy loads? What emissions does it have? Does it leave a carbon deposit in the engine under combustion like gasoline does, or is it clean burning like ethanol producing only CO2 and H2O? Lastly the BTU content is a red herring, as BTU is simply heating one pound of water one degree. Engines are not designed to merely heat water, its a byproduct of combustion and gasoline is still below 20% efficient, meaning it wastes 80% of its energy heating the engine, water, and air around it than powering whatever its being burned in. Ethanol is 40% efficient in the real world, 42% in the lab, at least according to the US Navy who tested it back in WWII. That means it only wastes 60% of its energy heating things up, which is part of why ethanol runs cooler. Candle wax and bees wax have high BTU content too, but they arent really good fuels for transportation engines. The comparatively paltry BTU deficiency of ethanol is nothing compared to the wasted energy of gasoline. So freaking what if butanol has almost as much BTU as gasoline, we arent heating water with it. My big issue is the water used in production and the lower octane. High compression engines are more efficient, which is why compression ratios have been creeping upwards and why we have direct injection showing up now, because its a bandaid for the crappy octane of gasoline. We are trying to get more from the fuel we burn, and squeezing it harder does that, the problem is gasoline cant stand being squeezed very hard and it explodes too soon, which requires retarded timing, lower compression ratios, and shedding as much heat as possible to prevent detonation. Carbon build up from gasoline negatively impacts the propensity to preignite, as well as wearing out the engine sooner. It remains to be seen how isobutanol fares in comparison. It might be a decent bandaid for gasoline engines, but it cant compete with ethanol in many areas. I think the biggest reason butanol has backing is that not any old Joe can produce it easily and cheaply in his back yard. They can control the production entirely, because the bacteria that make it will kill you if you try to make it yourself like you can make ethanol. the amount of water required makes it prohibitively expensive for the average Joe to to produce it, and the environmental impact would be massive if they started dumping the left over waste water. Think Canadian Tar Sands ecological nightmare and tailings escaping into rivers. Ethanol spills kill bacteria, but little else, and its biodegradable with sunlight and easily diluted with water.

    I just can't get over this price difference!

    Unless youre close to Wisconsin or Ishpeming, you cant fill up with it. I find lots of people who are ignorant about it, as well as dead set against it. There is a new gas station going in here in Marquette, one of the tribes owns it. They arent having E85 installed, not only no but hell no the guy I talked to said. Far too many people here think its horrible, probably because the prices are so high and they think it lowers mileage by half or some other bs. People cant believe my 1970 vehicle runs on it and doesnt have problems. I show them, have been driving it all over this summer testing and tuning on it, and still people dont believe it when I tell them it runs on ethanol. "It doesnt sound like a high compression engine." We arent going to get more pumps up here until people actually want to buy it. They arent going to want to buy it until they see how well it works, and its priced better. You can bet that once I have my stills up and running again, and I am burning my fuel, that I will make sure people know how well it works. Not that I expect more stations to start carrying it, they have a nice little group that keeps prices high and prevents us from having any choices in the matter.

    Must be nice, they are still gouging us up here, only an ten cent spread. Can't wait to get my stills up and running again.
  10. I was down there yesterday and never even looked. Yeah they were at most ten cents under 87. Ishpeming isn't pricing well either, and I'm not the only old car guy running it.

    $2.31 Super America Burnsville, Mn

    Must be nice. Its $3.59 here, they really dont care if they sell any.
  12. Dan, I was surprised too. I know lots of techs who hate ethanol, say you need twice as much, after run oil is a must, stainless everything, and it eats everything it touches. They don't know the difference between methanol and ethanol, and quite a few think moonshine is methanol. They simply don't know, and just because you're a mechanic doesn't mean you know anything about it. Most of them I know are simple parts replacers, not someone who understands things intimately enough that they can modify things to run better, and they look down on guys who can. Every car can run ethanol that has been built with a spark ignition, its a matter of tuning, not engine design. Can't test for octane, besides ethanol doesn't really fit the test they devised for gasoline. Its a lab thing only, I'm just a guy with old cars and a wideband O2, no laboratory here. Straight out of the still. Haven't made any this year because I had to start over almost from scratch when I moved, she got the old shop in the divorce. Been running E85 this year and testing/tuning with it. There hasn't been a cork gasket made for my cars in some time, not that it really matters. I had some in a Holley carb, they held up fine. Didn't see any problems I don't already see with gas. Cork carb gaskets went bad with gas too, but nobody wants to remember that. Fuel hose gets brittle, cracks then leaks with gasoline, the higher the octane the faster it happens. I have 7 year old hose on the GTO, and some is almost twenty years old on it, still works fine. I'm just not seeing the horrible issues I should be according to anti ethanol people. The GTO has had at least E10 in it since I bought it, to hear the naysayers talk it should have eaten all my carbs by now. I wonder what's in the shake oil they sell that is supposed to prevent ethanol from harming anything. How does it prevent something that doesnt happen?
  13. More corrosive over time in older vehicles. Yeah, I would have an issue with that statement, and that it damages old cars in any way, unless you somehow managed to keep all the original hoses and carb parts in it for the last 30+ years. Always hearing it, the same false BS about how bad it is for carbs. Methanol is, ethanol doesnt seem to be after running it for many years. E10 from 1994 until 07, then E85/HE100 for the last seven years with the original tank and lines, using modified old carbs from the mid 70s to run E85 and whatever I happened to have laying around for the E10. If there was going to be a problem, it would have surfaced by now, because most people dont drive the same car for 20 years. Know whats strange? When I have E85 in the car I get some white residue left over in the carb when the fuel evaporates over the winter. When its my homebrew in there, the carb is clean with no residue at all in the spring. Two different Qjets that sat for over a year before I put them back on the car for test and tuning, and the one that had E85 last had white stuff. Must be something they are adding to the fuel that does it, because 185 proof doesnt leave the ring on the float. It doesnt hurt or clog anything, just some white stuff stuck to the float and accel pump. This carb had HE100 in it. Looks brand new inside it.

    Special Oil for cars using Ethanol

    My oil has an ethanol aroma to it, no way around it really. Part of the reason you have to change it with gasoline is dilution by the gas. Since I run a carb in a 1970 vintage car, it smells like ethanol all the time. People seem to like it around here.

    Special Oil for cars using Ethanol

    Sludge and corrosion? That's gasoline they are thinking about. There are fuel treatments out there to keep carbs and fuel lines clean while using ethanol, any snake oil they can conjure I guess. They only thing you have to worry about while running ethanol is getting the oil hot enough to evaporate the condensation that naturally occurs in all engines. Anything to make a buck while spreading erroneous crap about ethanol.
