Fuel and water use to separate really clearly. Adding "drugstore" alcohol can help water and fuel to mix and run through, then be gone. You are not "running on alcohol", just helping water get through.

Water in the correct proportion acts like a higher octane fuel. Water injection works, and has been used, or at least experimented with for decades.

Might be a "moot" strategy with today's ethanol blend. At my nearest Chevron, it comes from the pump with the water already in the mix! I asked the owner, "what's this this stuff that separates when I leave fuel in a clear, sealed jug". He confidently replies, (arms crossed, leaning back on his heals, standing near his Corvette), "there is nothing in the fuel". I've now saved about 3 gallons of that "nothing". Burns. Kills dandelions. I'm gonna ask him someday what to do with all this "nothing" I have left. It has caused me allot of frustration and time in carbourated things like my dozer, water pump, generator, chipper, roto-tiller..... Maybe beter to not bother Standard Oil.

 

Not a clue

 

E10 is 10% ethyl alcohol by volume lol. Sunoco's 94 Octane Rating fuel up here is just 91 OR real gas bumped up with ethanol.

 

Lol i've never studied much into the addition of alcohol into fuel. The only thing i go off of is the stories of my shine running grandfathers.

 

If your tires are bigger than stock and you didn't change the spedo gear your mpg is wrong.

 

Alcohol ups the octane. Unless you are running a higher compression than 9.7+/- you are not going to get the full effect of the burn. High octane fuels burn slower thus needing more compression to burn fully. 87 octane is sufficient for almost any car, once you get over the 9.7/10lb compression mark then you start to get the effect of the higher rating(we do seem to run better on the higher octane whether we need it or not though).
As for more on the alcohol/ethanol/methanol there have been some articles written recently, and research done regarding the ante being upped in the regular fuel from the current 10% to 30%(the current 10% doesn't seem to hurt anyone). Consumer Reports and UL labs have looked into mechanical issues caused by a 30% mix of alcohol, and if what they say is true alot of us are in for engine rebuilds namely heads. Alcohol kills exhaust valves and seats due to its longer burn time and dry burn. Flex fuel vehicles made after 01 have all been built to deal with flex fuel whether they burn it or not. Vehicles made before the onset of this are the ones that were found to be affected, all vehicles made before 01.
A little alcohol doesn't hurt but alot will if the engine can't burn it properly.

 

It wasn't uncommon to find the engines modified to run on alcohol. They'd fill the gas tank with moonshine instead of gas. Radiator too. Excellent hiding places, lol.

 

You could have added, "don't shoot the messenger" Highmilage! Got any links? I guess Brizil has been 85% or more for a long time. After not noticing a problem with exhaust valve seats after going to no lead, naturally I'm suspicious of this now. Hotter or more corrosive? Deposits? Wonder where the problem is?

"A 2010 decision by the Environmental Protection Agency"


"the Auto Alliance, an auto industry lobbying group representing several major automakers" "Testing 16 vehicles, with eight different engines on a 500-hour durability cycle"


(Our tests were based on a vehicle running on E85, a blend of 85 percent ethanol with 15 percent gasoline that is approved for use only in specially equipped "flex-fuel" vehicles.) "


I didn't read through, but right off, An industry lobbying group? I wonder if anyone got a picture of the damage it causes.

 

I get 17 mpg on petrol and the equivalent of 30 mpg on LPG.. Petrol is now £1.40 a litre whereas LPG is 70p a litre

 

Interesting... How difficult was the conversion? I would consider the biggest problem in North America here to be the availability of the LPG (When compared to the number of gas stations). Also, the price gap between gasoline and propane isn't as large, at least where I live. How is the power compared to gasoline?

 

Don't shoot the messenger...LOL.
Guess RADI found one of the articles I read. I would like to see one of the heads myself, but from personal experience it's kinda ugly. you can get a 10 to 20% ethanol mix in the midgrade in Missouri(also 10 to 15 cents cheaper than regular) ran it for about two years. The last six months, or so, of running it was having some stumbling, missing, backfiring. Thought it was the cracked head I'd been driving on NOPE, all of my exhaust valves were burnt and beaten into submission. The machinist told it was from burning that **&^%$# midgrade fuel with the &*)&*^%$#@$! ethanol and to #@#$^%* stop using it. Got a new (to me) head off a Jeep, with 290,000ish mi on it, that got caught in a tornado, and still running on that one 5 years now.

 

^^ this. And the new speedo gear would have to match the axle gearing as well..see here

I got the kit second hand for £200 it has a small steel petrol tank which holds about 20 litres and a 70 litre gas tank which all fit where the original tank used to be it took about 8 hours to install. no real noticeable loss of power. can be topped up by pumping from domestic calor gas cylinders though this is illegal lol!
