RAY I LIVE IN INDIANA AND HAVE TO AGREE WHOLE HARTEDLY. I THINK THERE IS SOME DIRTY POOL BEING PLAYED ON US. THE FUEL DOWN HERE AS YOU PUT IT IS VERY CORROSIVE!! AND WONT KEEP MORE THAN A MONTH OR 2 AT BEST.. MY SNOWMOBILES ARE A SOB TO START AND THE LEST WE EVEN DISCUSS THE CHAINSAWS AND WEED EATER. MY GOODNES YOU CANT KEEP FUEL LINES ON THEM OR START THEM RELIABLY. ALCAHOL FREE GAS DOES RUN BETTER THAN THE SWILL WE GET SHOVED AT US. BUT… GET THIS …. MY 4 STROKE YAMAHA 426 DIRT BIKE LOVES 93 OCTANE BLENDED FUEL. I PUT RACE GAS IN IT AND COULD NOT KEEP IT RUNNING.. WHAT ARE THE ODDS.. ANYWAY WE HAVE EXPERIENCED MASSIVE CORROSION OF THE GAS SYSTEM INCLUDING THE CARB BOWLS BEING CORODED TO THE POINT OF HAVING TO REPLACE THE CARB. I WAS SHOCKED!! SOMETHING IS BEING PUT INTO THE FUEL OR SOMETHING, I THINK TO CAUSE THIS. ( ON PURPOSE I THINK). WELL JUST MY RAMBLINGS JASON From: 1962to1965mopars@xxxxxxxxxxxxxxxx [mailto:1962to1965mopars@xxxxxxxxxxxxxxxx] On Behalf Of Raymond J. Henry That’s interesting. Because ethanol blended fuels give a higher effective octane rating. Meaning that is ACTS like higher octane, not that it actually HAS higher octane rating. Which is why it’s been such a big hit around here since the 80’s. The trick to making blended fuels perform better is to simply run a slightly richer mixture. All of us that have been using it for decades up here in our older and performance vehicles don’t have any of the “problems” that are being reported in recent years by those in areas that are now forced to use blended fuels. Which makes it very interesting, indeed. Why no problems in Canada for decades, but all these issues in the U.S.? My half million miles or so experience with blended fuels causes me to wonder if your octane rating South of the border are perhaps fudged somewhat? Mohawk (now Husky) actually sold ONLY E10 fuel for the longest time. Once blending was legislated, they then followed the other stations with using non-blended fuel for their 94 octane fuel. The resulting backlash against that was so strong that they then re-introduced E10 94 octane. That was primarily due the to petitioning of guys with older muscle cars, etc. On a side note, when I went down to the unveiling of Miss Belvedere, I was running a ’65 Valiant with slant 6. At one point, I noticed that E85 was being offered at a gas station for substantially less than non-blended. So I topped off with half a tank of the stuff. The half tank that was in there was the standard “may contain up to 10%” blend. I noticed no change whatsoever in performance or mileage (and I checked the mileage every tank). Nor did I encounter any of the problems I hear so much about. That car is still running without any fuel/performance issues, almost 100,000 miles later. And all with blended fuel. No fuel lines, carb, gas tank replacement since 2000. Prior to that, we don’t know. The tank does look original, and there is no rebuild tag on the carb. Rubber line between the frame and the steel line up to the carb have been changed, but not since purchasing from the original owner in 2000. We have what is claimed to be the largest number per capita of special interest vehicles on the road here (I can’t either deny or support the validity of that claim), and all of us that I am aware of have been running blended fuels, like I said, since the 80’s. Now, that’s E10. The M5 never took off, I don’t know why, never ran it myself. It’s my understanding that the “new” blended fuels are pretty much the same as the E10 we’ve run here, except that they don’t have the guarantee of 10%, they may have “up to 10%”. When I was working as a GM tech, they did warn not to exceed 10% ethanol, and that no amount of methanol was acceptable, or you could void your warranty. GM also stipulated that E10 was perfectly acceptable, and that it would have no undesirable effects on their vehicles. The story was that exceeding that concentration (or using methanol) would damage the injectors. Nothing was ever mentioned concerning other components. It’s very common for me to put on 1,000 miles/week on whatever old car I have during our cruising season (May – November in a good year). Never once have I had any components fail due to the rubber breaking down, nor have I been subjected to idle or performance issues as a result of it. This is a subject that has come up hundreds of times with friends and family South of the border. And it just seems flat-out weird that you guys are having all these issues with something that’s worked, literally, for decades up here without those issues. The same fuel that’s causing grief for you guys was embraced years ago by guys running identical stuff up here, without any problems…. We’re all getting better performance, better idling, better mileage…. What are they adding to your fuel down there with the ethanol that they don’t use up here? In ~1985, I made a trip down through Montana (I have family there), as well as hit up the Black Hills area. I was surprised to find some of those country gas stations at the time had some pretty low octane ratings. At one point, I was down to 81 octane. Pinging became a problem, and backing off the timing only resulted in having real trouble getting up the hills with that 1800 cc engine. The engine bottom end was untouched, but I had done the valves. At the time, I had installed a head gasket that was about ½ the thickness of the factory. So I do not know what the compression ratio was. I finally figured out how to combat the pinging issue, and that was to hit up a farmer’s supply outlet, and buy gallon jugs of ethanol, and blend my own E10. By adding a gallon of ethanol to my tank of pump fuel, I was able to return my timing back to where it should have been, and all my problems went away. However, on that trip I did have a fuel pump fail. But that was the factory pump with around 300,000 miles on it. The pump was replaced, and still ran fine until the car was totalled in an accident some years later, with a documented 500,000+ miles on it. The carbs had been services a number of times, but only the base gaskets were changed as needed, and one replacement set of needles/seats. Floats were original, as were the float needles. I have no end of stories about how well E10 has worked for me, and how I’ve never had any issues from using it. Only good results here. So you can see why I’m thinking that there has to be more going on with your fuel down there than just the addition of ethanol…. -Ray From: 1962to1965mopars@xxxxxxxxxxxxxxxx [mailto:1962to1965mopars@xxxxxxxxxxxxxxxx] On Behalf Of Daniel McCormack The Non ethanol ran so good in my 78 D-150 that I just came back from filling up my 68 Dart GTS stock 340. I’ve been hesitant to try it in the 340 because it’s only 90 octane and I’ve had some pinging problems with the 93 octane ethanol. Well guess what, I have no pinging at all with the 90 octane non ethanol. Interesting! From: 1962to1965mopars@xxxxxxxxxxxxxxxx [mailto:1962to1965mopars@xxxxxxxxxxxxxxxx] On Behalf Of cudaus1 Here in Florida the Governor allows Non ethanol gas to be sold in the state. Very few Marathon stations have it but at least I have one not far from me. The price is about 4.59 a gallon and it's only 90 octane but it better than putting the other crap in your Mopar. The ethanol ate up the fuel tank seal in my generator. Nasty crap! -- -- -- Please address private email -- email of interest to only one person -- directly to that person.
