Trump puts EPA's ethanol program on ice

[Norm Lenhart]

Didn't read the whole thread but if it wasn't posted, to run modern gas in old engines (pre ethanol idiocy) you pretty much need to replace every fuel line with one alcohol comparable and rebuild the carb with an alcohol carb kit. For Holley carbs it's easy and they are easily available. I would imagine with the abundance of issues, there are simmilar kits for most mass produced carbs, whether chainsaw or car.

Your other option is to replace all your fuel line and rebuild the carb at LEAST yearly or you will end up leaking/blowing raw gas all over your engine. More frequent oil changes and a bit of oil added to the gas is also a must.

Read up thread a little Norm!  I think we have found a cheap and efficient way to simply eliminate the problem.

You are a braver man than I. Back in NY, water in gas never ended well regardless of what we did with it. after. Condensation in the station tanks was a big seller of white gas to mitigate it. I'd be leary of trying to settle it out, to say nothing of the hassle involved.

One think to know is when you remove the ethanol from gasohol using water, the octane will drop around 2.5 points.

@Elderberry

That surprises me!  I thought the exact opposite would occur. Would you mind explaining how removing a lower BTU per volume liquid from the equation lowers the octane rating?

[Elderberry]

Ethanol has an octane of abt 113(RON). So added to gasoline, it raises the octane of the gasoline.

[Elderberry]

Low octane gasoline has a higher BTU/volume than high octane gasoline.

Didn't Lead do that also?   Ethanol Good.  Lead Bad.   

All I know is back in the day I had find "a Guy" who had a 55 gallon drum of 110 octane Racing gas.  I'd take it home and do a 50/50 mix just to keep my 71 Pontiac 455 engine with 10.5 to 1 compression from blowing up.  Even then I had to retard the timing for daily driving.  The advance it when I was out being stupid.

That is twisting what Jesus said.

Better read up a bit more in your bible.

You're the one doing the twisting - big time.

Good ole Tetraethyllead. It also cushioned the valves. When leaded gas went away, engines had to have hardened valve seats.

Am not twisting anything, just reading Luke 15 and the Prodigal Son.

Since it makes no difference to Him on whether one is honest his entire life or just recently repented of his past, it sure should not make any difference to you or me.

Tough for us humans to acknowledge, but there is a lesson there.

You guys are pissing off Mod 8. Knock it off!

OK! Thanks!  Still there is something in that Octane rating calculation that is confusing me.  Alcohols have a much lower heating value per volume than c₅ gasoline.  Something is not computing.

Tetraethyllead does two things when added to gasoline, 1. it levels out the burn rate better than anything else known to man and 2. when burned in the combustion chamber the lead is released and provides the cushioning effect mentioned above.

I personally wish we could still use it!

I don't know what you just said...but I agree!  More cushin for the pushin

I dunno. Here, the E10 varieties are 87 and 89 octane and the No ethanol 'premium' is 91 octane. It's more expensive, but delivers a little over 10% better gas mileage than the E10 87 octane, and I haven't had fuel system problems in vehicles I use it in (or the small engines I feed it to). After replacing carbs on a snow thrower and having two weed whackers, a lawnmower, and a hedge trimmer bite the dust, I'll pay a little extra for the alcohol free fuel.

Yeah. I pumped Ethyl back in the day...when I wasn't working construction on the mountain in the summer.

I wish I could buy alcohol free gasoline at anything like a reasonable price nearby but it is simply not available here short of buying avgas at the airport. I can do that but kind of feel stupid asking the guy driving that big ole truck to fill up my little five gallon can.

I'm going to buy some of the higher octane stuff we do have that contains ethanol and try the adding water and decanting trick!  What the heck! It's worth the price of a gallon just to find out.

Octane rating is NOT based on BTU/lb or vol. It is based on the fuel's ability to withstand compression without igniting.

Ethyl probably wouldn't appreciate you putting her name in the street like that!

 OK!  NOW I remember! You know what they say! Use it or lose it!

Sorry, @MOD8 .  I got the conversation wound up again on topic to discuss ethanol but there are a couple who keep trying to divert to how dastardly someone is doing the right thing.

For two bucks, you could go all weekend,  too.
