    Doing some yard work today and it seemed that every piece of OPE I owned is out of fuel...mower....quad...tiller. I grab the 5 gallon can and run into town. The place I normally get gas has all of its pumps out of order...no idea why...so I run down to the next station down the street. I don't usually go here because they don't have pay at the pump. I look at the pump and see that they have 100% gasoline in 93 octane for about $.20 more per gallon. I figured, why not?

    I topped of the quad and dumped the rest in the mower and proceeded to mow. Hmm...seems to run pretty good...especially in the deep thick stuff when you load down the engine. I get done mowing and run around on the quad for a bit. It is definitely snappier. Throttle response is real good.

    I fully realize that octane does NOT increase HP (only in there for knocking), but I'm not so sure that 10% - 12% of corn liquor they are putting in gas these days isn't decreasing it. I used to think that was a myth but I'm not so sure now. Can't wait to run some through my saw. I figure I'll dump 12 more gallons in the mower ( o_O ) to top it off and use the rest to make a fresh batch of 2-smoke mix.

    You're making the common mistake of associating octane with the energy content of the fuel. Ethanol is used to actually boost the octane of the base fuel. But ethanol does not match pure gasoline for energy density so it does "water down" the fuel a bit.

    I think I pretty plainly stated the I realize octane doesn't make more HP. Ethanol has 33% less energy (per gallon) than gasoline. So E10 gas only has 3.3% less energy per gallon, but it sure does seem like more than that according to the ol' butt dyno.

    I can't wait till the Country we live in, realizes that it isn't cost effective to make fuel from corn. It cost entirely to much to produce, and then it not only destroys parts of the fuel system, but dumbs down our actual fuel and absorbs water over time...

    Tell me how this is good for anything? ?
    .I wish we had more non Ethanol stations around me. :(

    Got to keep them row crop farmers happy...cattle/hog/dairy/poultry farmers be damm'd.

    I like my corn liquor aged in oak barrels, then in a glass with a couple ice cubes.

    My truck supposedly makes more HP on E85 than it does on E10 or E0. Fuel gauge moves awfully quick running the corn juice tho. Too quick to make it even close to financially sensible.:confused:

    I don't know how I missed that Luke. I need to go put myself in a forum time-out for awhile I think.:confused::emb::loco: :crazy:

    Lot of fine young people have lost their lives in wars over oil supplies - not so much with corn.

    They tried shipping ethanol up here & adding it to the fuel.
    Cost was nuts.
    Now we have straight gas.
    Hope that stays but some bureaucrat will find a way to line
    their pickets $$ & get it back in Alaska sometime in the future.

    Fresh gas is important too. A good metal sealed can for storage helps keep it fresh.
    I mix 1 gallon batches for the saw. Fresh is good & non-ethanol is better :)
    Most 2 stroke oil has fuel stabilizers in it.

    Yup… firing up the Keystone pipeline would be a great start on energy independence. Don't hold yer breath…

    We had one local station that carried non ethanol 87 octane gas up until a month ago. That's all I've ever run in my small engines like the garden tractor, etc. I ran a couple of tanks through my Subaru last summer to compare fuel economy with the 89 octane 10% ethanol blend and at that current price difference ( $0.020/gal I think), the non-ethanol was worth the extra money but not by much.

    Probably like others, my biggest concern is whether or not the ethanol is harmful to these small engine components. I've heard it'll dry out rubber fuel lines and gum things up quicker, etc, etc.

    Is this a legetimate concern? I leave fuel in the garden tractor year round because I also run a snow blower on it. The generator also holds stabilized gasoline year round. The little engines....weed whacker and chainsaws get put away dry after each use or never have fuel in them more than a week.

    Ethanol is hard on rubber, but I leave fuel in all my equipment year round and have never had a fuel line fail.

    You will have very little trouble with equipment that you use/maintain on a regular basis. It's when the equipment sits in storage for long periods with untreated fuel in it that the real damage is done.

    Certain plastics and rubbers do not get along well with the ethanol either. Ever have a Poulan/Craftsman chainsaw that the gas cap swelled on? Had to go get the channel locks to get it open didn't ya? ;)

    Non E 93 octane is what I run in my saws.
    Non E 87 in all other vehicles.
    We don't really need the ethanol and we don't need to go to war over oil either.
    What we need is to get our head out of our ash.

    I have been running 110 racing fuel in all my yard equipment saws, mowers, weed whips and leaf blower and also my genny let me tell ya that makes a world of difference. Since I started using it in the leaf blower I haven't had to clean the carb once! It cleans it for me... That has to help the power.

    We have Non E 87 and premium. Not sure if it is 91/92/93 octane though. It hours in my boats ATV, saws weed eaters , and mower sometimes. But usually just run E10 in mower.

    I'm gonna load my splitter up with racing fuel next time just out of curiosity maybe it will smoke like an old jalopy for a while and clean out too lol. The lead is a nice lubricator too. The stuff is $7 a gallon and doesn't go bad for years so once a month or so I might run that through the splitter to clean it out.
