Funny how here in Iowa non ethanol 87(all gas stations) and 91 octane is plentiful. We also have 10,15,20,30 and 85% ethanol blends. Here at Paullina Avgas is $4 per gallon,E0 91 is $3.50, 87 E0 is $3.10 and E10 87 is $2.80. E85 is $1.90
MMO, some wintergreen oil for odor, a little red dye for color, mineral spirits at about 20-30% and some variation of naphtha for the rest. Believers gotta believe. LOL
25+ years ago at Oshkosh I sat in on a radial engine clinic, there was more then one speaker. One old weathered gray haired who was the last to speak was the most interesting one. He had run the engine repair/rebuild shop for TWA when they were flying the Constellation. He was taking answers from the audience when someone asked about MMO, wanted to know his opinion on using it. I don't remember word for word what he said but it was something like this. " No one can tell you what it does, and it's not FAA approved, but I can tell you that TWA bought 55gals drums of it by the truckload."

I did a little research, it is all driven by EPA National; Air Standards. They take air readings and if the emissions are high in a certain county they adjust the formula.

Meaningless trivia. They ran their engines hard. They ran their engines often. And they ran them lean of peak. Everyone has a gut feeling about why certain practices work. Usually based upon what someone else told them back in their youth.
Mike, E85 (105 octane) likes high compression which your pickup wasn't. But if you notice the prices in the picture from whenever, E85 was 98 cents less and I bet it would have worked price wise. My 2017 Ford Focus has variable valve timing and direct fuel injection into the combustion chamber. Last week when I filled I got 32 mpg. It will run on 87 octane too by changing valve and fuel timing. One time I had to drop to E30 and my mileage went to 40 or a little more. I guess I should see if it will get 50 on 87 E0 but just can't bring myself to do such an evil thing. A big Continental that I know of has been using E10 since 2006, the exhaust pipe has a nice tan look. Before trying the E10 and using 87 E0, the exhaust was black and sooty. Sparkplugs were too but not anymore---they're beautiful and compression after 225 hrs is all above 75/80.
You are right about rip off. Today's close for June Nymex RBOB unleaded gasoline was $2.18 and CBOT ethanol futures $1.50. No subsidy $$$$ in the ethanol either like some people seem to think. Another thing I read from some people is how E10 loses 10% miles per gallon and I wonder what are they smoking. If the ethanol is blended with the same gasoline that is E0, then there are 3.5% few btu's in that gallon but if...... Texas is a special place----the state goes around and does random samples at gas stations and one time they found either 1/2 or 1 % of a tar like molecule that didn't actually burn in the gas. What a wonderful way to get rid of junk for a nice profit.Uh, nope. In fact, E-85 was slightly MORE expensive than E-10 at the time....a total rip off.
I'll have to admit, I've never been super aggressive doing that. I still have to think with E10 that all that oxygen mixed right in amongst the other hydrocarbons that the burn is more complete and not still burning as it goes by the exhaust valve.As to E-0 in aircraft engines, you need to remember what the red knob is for.....
Agree, but we have both had cubs with little Continentals, I think I remember you having some stuck valves a few years back. Mine in 4200+ little C-engine hours have not. : - )

Farmboy this is for you. My Mom bought this Lawnboy back in 1993 and it has used 10% ethanol since about 2000. The fuel I just dumped in was mixed last September and it just started on the first pull. Around here lots of straight pipe from the engine new diesel pickup. Some even have a "power" button in the cab that they can fog major black smoke.

https://www.reuters.com/article/us-...hardship-waiver-from-regulation-idUSKCN1HA21PNEW YORK (Reuters) - The Environmental Protection Agency has exempted one of the nation’s largest oil refining companies, Andeavor (ANDV.N), from complying with U.S. biofuels regulations - a waiver historically reserved for tiny operations in danger of going belly up, two sources familiar with the matter told Reuters.
Farmboy, You removed all doubt for me now and I probably shouldn't even respond------I think this is 2018 and just a few changes have been made. There are no subsidies or tax credits and the mandate to blend ethanol by oil companies is even changing. This is old news from April 2018. Heck, even major refiners are claiming hardship and getting out of there mandate to blend ethanol the last few years even before Scott Pruitt who seems to be expanding on the waivers. It was supposed to be for the one horse small time refinery but like I said times have changed. You really need get up to speed.
