Home Forums Hunting & Shooting Hunter's Campfire Other uses for blue avgas, besides aircraft?

What all can blue avgas (100ll?) be used in?
Boats, generators, lawnmowers,, etc?

I can get quite a bit free, but not sure what I can do with it.

Any ideas?

I know its heavily leaded, but I put "regular" gas in my unleaded jeep cj-7., back in Germany. No issues.

I run all 2 cycle motors with AV gas. Chainsaws, Lawnboy mowers, Shindaiwa trimmer and Mercury OB.

burning chit in cut in half 55 gal drums..............

Pretty much anything without a catalytic converter.

Lawn mowers, chainsaws, old muscle cars, 2 cycle dirt bikes. If you've got any dirt track racing or a drag strip around they'll want it.

I have o2 sensors in my exhaust, but no cats.
Don't think so because the lead will mess the sensors up?

Looks I gotta get more barrels to store it. Couple hunter gallons will be nice for prepping. My Honda generators can run for a long time if ever needed.

I use 100LL for all my 2-strokes and lawnmowers- it's way easier on the rubber than mogas. If I could get a bunch free, I would buy an older truck just so I could run it! If you run it up pretty good once in a while, you will keep the lead down. The spark plugs on electronic ignition motors have a pretty big gap which keeps them pretty free from lead problems.

I also use it for a solvent- it is not as flammable as gas and it is not as stinky!

If you lived closer, I would buy a bunch from you to run in my hot rodded Harley. Especially on Race days. High octane allows for some wickedly advanced timing in a 4 stroke motor.

Heck, for enough of it I would make a trip down there, and you could make a little money on the deal.

lemme see how much is available.

Anything that doesn't have a catalytic converter. It's just 100 octane leaded gas. The old 115/145 octane gas was too much for standard compression engines.

Man I wish I lived near you. The stuff is magic on all non-cat motors. I too run it in all my 2 stroke stuff and my lawn mower.

Too much in what way?

I don't know the reason but I served with some older recip engine guys in the AF and they said you had to rotate tanks of gas in your car if you used 115/145. IIRC it was hard on valves but that was a long time ago when they told me. If I understand the octane thing right, the higher the octane, the slower the burn rate.

Low-Lead is a relative term that references only older avgas formulas. Enough lead is in 100LL to foul plugs and sensors, but a lot of small engines (Generators, Compressors, WeedWhackers, etc.) at small airports are fed mostly on discarded fuel samples of it.

It should say lower lead. I think it is still around 2 g/liter which is a fair amount. It can leave lead deposits on stuff. I think the 115 octane stuff has about 4-5 g/l in it and is really hard on stuff.

I suspect it could play heck with O2 sensors and such in modern vehicles. Even though we only have idiot lights on most newer vehicles, the computer is fed by a host of sensors that really monitor a lot of things.

Isn't the blue 80 octane ?
Green is 100 LL.
Or was the old red 80 ?
Mike

80/87 was / is Red

100LL is Blue

So basically, it boils down to running it in most anything except vehicles.

Looks like Im going to have a couple hundred gallons on hand for my gennies in case of emergencies!

If the avgas is available for non-av use due to being leftover samples or because it failed a water test, I'd dose it with Heet and Stabil or similar additives. Since it may have water and may not be any too fresh.

I know the guys that ran old 60s muscle cars back in Minnesota on night there were car shows and get-togethers always bought AV Gas over at the Crystal Airport...

Conversion to Propane was the other popular route to go...
