I have been reading that some people put Avgas from local small airports in their old military trucks, has no ethanol and is leaded. Thoughts, experience, feelings?

You can get ethanol free gas at some regular gas stations, and by now most old engines have had hardened valve seats put in so they don’t need the lead and those old military engines don’t need high octane so I’m not sure that it’s necessary.

I can’t get ethanol free here, except at the race track, which is a bit far for fill ups. The airport is actually not very far. We will probably rebuild the engine so that stuff isn’t an issue. I just read that if you have to cat and no O2 sensor you are good with the 100LL.

If you can’t get ethanol free then I’d probably go for the av gas too since it will probably sit for extended periods and that’s when ethanol becomes an issue. You could probably get by with a fuel additive, but if you can get the av gas easily then why not?

If you live near water, a lot of marinas and gas stations that cater to the boating crowd have ethanol free gas as well.

I doubt that 100LL is necessary, but it sure won’t hurt anything.

I used to work as a refueler at a small airport and would bring home gas for my dad to run in his Oldsmobile. It definitely ran just fine on it so I can’t imagine any issues you would have.
You will want to check with the airport to see about buying fuel. We had to have people that bought it sign forms saying it was for off-road use since we didn’t charge road tax on the sale, but some airports may have different restrictions.

My uncle has a 1969 440 road runner that’s all original and he has been running Av gas in it for decades because it’s leaded and ethanol free. Plus the 110 octane doesn’t hurt either for his high comp engine. Other then the higher cost he hasn’t had any issues and gets it from his local municipal airport

It makes an amount of sense, I mean it might be closer to the gas they were designed for. But if it’s not cheaper than getting ethanol free gas at a regular station, I don’t see the point.

Should run fine, but like kiltedpadre it isn’t taxed like regular gas. not sure of the penelty getting caught using it.

Hmm true, although it would be in a 50's power wagon so not too hard to believe it’s for off road, except you have to drive on the road to get there...

We used to race with guys in the 90's and early 00's who ran avgas in racecars with older, carbureted high compression engines. While these engines had all been rebuilt many times over with hardened valve seats, I recall them running it because they could buy it far cheaper than actual race fuel.

Unless the carb has a cork float, I can’t imagine any reason one would go out of their way to get ethanol free gas for something like this. Install hardened valve seats and you won’t have to worry about lead either. Leaded gasoline is highly corrosive - a big reason exhaust systems now last 20+ years is because leaded gasoline has thankfully vanished from the roads. Ask anybody who worked in a muffler shop in the 70s or 80s... exhaust systems always rusted from the inside out back then (also you didn’t expect a muffler to last 10 years either). Further, leaded gasoline is pretty hard on the insides of engines too.

If you’re cleaning out the whole fuel system, you’ll be fine with ethanol blends. I worked at a marina during the mandated switchover to E10 and we saw the worst issues with older boats (like, 40's through 80's) where the old fuel tanks, lines, carburetors, etc. would get cleaned out and then filters and carbs would get clogged. Once we got through the initial cleanout, things worked fine. I even clogged up the filter on my ‘89 inboard ski boat the first time I put in E10. Must have loosened up deposits of “varnish” and whatever from my tank. I cleaned the fuel pickup, changed (both) fuel filters, and never had another hiccup.

Yeah, we will likely change all hoses and lines. I run seafoam through the Z and use a fuel additive to keep the varnish away. I might have to buy by the gallon now, I do it every few months.
