dweese Posted February 12, 2016 Share Posted February 12, 2016 It has been a loooong time (over 10 yrs) since the difference between regular and premium was 8 cents. More like 15 to 18 cents. Ya filled up today at the local shell.. reg was 87.1, 91 was 105.9 Link to comment Share on other sites More sharing options...
Viperules700 Posted February 12, 2016 Share Posted February 12, 2016 Ya filled up today at the local shell.. reg was 87.1, 91 was 105.9 Wow! I never pay attention to the difference. I just pump it and pay. I do put 91 in my snowmobile, and most small engines thar I don't use ever day. Maybe I am burning money, I dunno. My garden tractor seems to get an extra 1hr or so out of the 91. Maybe it keeps engine cleaner, don't really know. Link to comment Share on other sites More sharing options...
thetorches Posted February 13, 2016 Share Posted February 13, 2016 Just filled up at Costco. Regular 87 was 80.9 and premium 91 was 102.9. Sticker on pump said 87 is up to 10% ethanol, no sticker on 91. Link to comment Share on other sites More sharing options...
dweese Posted February 13, 2016 Share Posted February 13, 2016 Sticker on pump said 87 is up to 10% ethanol, no sticker on 91. I went reading, and from what I can find they only have to sticker (and even that is loosely worded) the E10 on the 87 grade fuel because that's the only one controlled under the ethanol law. So the 91 may or may not be upto 5%. Shell is the only one who openly says 0 ehanol in thier 91 fuels. I tend not to belive those who don't tell you either way.

Wildbill Posted February 13, 2016 Share Posted February 13, 2016 I have been told that it costs more to make ethanol than real gas Link to comment Share on other sites More sharing options...
manotickmike Posted February 13, 2016 Share Posted February 13, 2016 It takes more energy to produce than it provides. After the subsidized farming. Then they move it around on a truck. Just what I hear. At today's oil prices I can't imagine the cost/energy ratio "defecit". If the pump says no ethanol, they have to be able to back it up. Testers are cheap, lotsa guys have them. Just remember on a pump that blends fuel to pump the first gallon or so into the car to clear the line of it. I just have a hate on for it after tearing into carbs on friends dirt bikes, and all the yard equipment. Gas can gum stuff up, ethanol corrodes the metal, and can clog or restrict orifices and jets. It's cost me a LOT of time and $, and I've seen more than a few roasted 2t motors. Link to comment Share on other sites More sharing options...
revrnd Posted February 13, 2016 Share Posted February 13, 2016 I have been told that it costs more to make ethanol than real gas Also there is less BTUs of stored energy in a liter of ethanol vs a liter of gasoline Years ago Holley came out w/ some specially designed 4 bbl carbs for racers using alcohol. The passages were cast/machined considerably larger to flow more volume (to allow engine to produce the same HP as a gas motor). In a street vehicle this would be seen in lower fuel economy.

Techdenis007 Posted February 13, 2016 Share Posted February 13, 2016 I read a report on E15 fuel mileage on full size pickups. Nissan's Titan rated about 22 MPG on premium, E15 rated about 10 MPG highway. Way more expensive to manufacture and less energy. Highly corrosive on rubber and other engine parts. E10 isn't far off ... should go premium for a month and see if there's any difference. Link to comment Share on other sites More sharing options...
Viperules700 Posted February 13, 2016 Share Posted February 13, 2016 I have been told that it costs more to make ethanol than real gas One bushel of crap quality corn yields about 10 Litres of ethanol. Corn runs about 5 dollars a bushel with trucking to the plant. So that works out to 50 cents a Litre for sone of the input costs. Factor in facility, labour, energy. Price would have to double I would imagine, but wouldn't know for sure. Link to comment Share on other sites More sharing options...

The wife's van was Flex Fuel rated so I gave a tank of it a try since it was also around 45 cents a gallon cheaper at that time. Lost about 25% of the range on a tank..
