Yeah! For those that have good old fashioned "burn barrels" made out of 55 gallon drums for burning trash, filling them with loosely packed trash, dribbling a half gallon of old gas on top, waiting about 2 minutes, and then lighting it makes for a pretty satisfying explosion and fireball. Don't be close to it when you light it off, and be prepared to chase down flying, burning pieces of trash!!

Us country folk have it made when it comes to good old fashioned, dangerous fun. So far, in most cases, we can get away with things that would make you a guest of the local jailhouse in or near the city....

Really though, how hard is it to do the right thing and run fresh fuel? It is a completely negligible cost, and just a few moments of your time. Your plane and engine are worth it.

As far as the Rotax info being outdated, our fuel keeps DEGRADING in quality, not the reverse. Just ask any hot rod or race car engine builder. (Like me.)

Lastly, ask your engine manufacturer if he would rather you run old fuel, or fresh fuel in his engine. Guys, it's really a "no brainer".

I disagree with the 2 months or so. I have used mixed gas for a good year without issue.

Oh boy..... Do you know what that sounds like to a retired Firefighter/Paramedic? It's called "Hazmat" and we're the ones who get to respond first to any issue regarding those materials classified as such and even worse, those which are not properly classified.

When we have to bring an Ambulance along to take care of whoever lit the thing, that's the worst of all for everyone involved.

Now I did my share of dumping petroleum products on the ground while doing my aircraft mechanic thing. Full scale aircraft use LOTS of oil and when we did a change at the airport, we just took the drain buckets out behind one of the hangars. Can you imagine what would happen now if such an activity were going on?

Next part is that when you sell Real Estate, especially a bit larger than a normal home or "out in the country", they'll test for petroleum distillates as well as pesticides in the ground. When I sold my 7 acre piece with a home on it several years back, I caught hell over "dumped oil" in the gravel driveway next to the house. How'd it get there? I don't think I've ever seen a tractor or piece of farm equipment that did not leak something.

So just be aware you guys.....

Unless it smells really bad, just dump it in your car as long as your car has a half tank or more of good gas in it. It will be fine. If it smells pretty bad, better to take it to a disposal center.

But my way is way more fun.....

Sunoco standard 110 race gas. Stays fresh for two years...not that you would have it sitting around that long. And it smells awesome! I get if from a local race engine shop. And it doesn't eat carb diaphragms like pump gas does.

Sunoco has good gas available. Wish we had it here in the west. I use avgas in my hot rod engines. The cost of race gasoline is just crazy....

Expensive yes, but I certainly don't go through it like when I had my '70 Chevelle at 9 mpg! You can get a 5 gal. can shipped to your house for about $70. 5 gallons lasts a while.

My friend used to get 55 gal. drums of the Sunoco racing gas shipped into Utah for the race car. It was a '69 Camaro with a 292 c.i. V-8 engine running the old C/Super Modified class in NHRA drag racing. We used to burn just over a gallon per quarter mile run....

Sweet! But a 292? That's a 6cyl. Maybe it was a DZ 302.

Some of the gas stations in towns near the Colorado River in Arizona, or the lakes it feeds, like Lake Havasu, have Avgas pumps in town for the hot rod boaters to fill up. The airports is where I used to go, but things have tightened up and some airports don't want to pump Avgas into anything but airplanes.... Anyway, it works fine, is stable, lasts for a long time, smells great, and my 13:1 compression big block Chevy in my race boat loves it. I would tell you that the 550 horse 454 in my Chevy Blazer loves it too, but then I'd have to kill you because it's illegal.....

Contrary to popular belief, running it in an engine that doesn't have high compression will actually encounter a slight power loss. Keep an eye on your spark plug for lead fouling as well.

Nope, it's a 283 Chevy V-8 bored out to 292. It was a better break on total car weight which IIRC was 10.5lbs. per cubic inch and kept the shorter stroke crank. It idled at 4500 RPM, out of the hole at 10,500 RPM.

A 292 small block Chevy engine was a 283 bored .060" and was quite common back in the day, especially before the 4" bore 327 blocks became available in 1962. In later years,there was also a 292 combination that used the larger bore 350 blocks combined with a super short stroke crank for some racing applications. And yes there was the old GM cast iron Duke 292 6 cylinder engine and even the Ford "Y" block 292. Not an uncommon engine size.

Man, when those old Ford "Y" blocks threw a rod, it sure made a mess didn't it? I've seen it many times.

But isn't the old Iron Duke a four cylinder? I had one in a Firebird years ago. Wish I had never sold it as that was a fairly rare combo. It was actually pretty "peppy" and got great gas mileage.

Oh yeah. Those short stroke Chevys could buzz the rpms like a chainsaw, and stay together too!!

Eh, if I still had my '69 Camaro and tons of money, I'd have a supercharged 632 mountain motor installed!! Maybe I'll get lucky when retirement comes lol.

And that engine probably lasted for what, maybe five passes? That's a lot of money to get that engine to turn 10,500.

Not so, the engines held together really well as Av8or1977 noted. We had two of them and they got fresh rings, bearings and any valve springs that needed replacement before every meet. Once we got the rest of it figured out, the valve springs were the biggest hassle of the whole deal. They were oversize and required the spring pockets to be enlarged which tended to create antifreeze leaks when the edges of the pockets got too thin. So later on, those pocket areas were augmented inside the ports. But with the high lift, long duration roller cams and high RPM, the springs just didn't last long.

The baddest stocker type engine in that era was the Chevrolet ZL-1 which was an all aluminum 427, it was actually Chevy's 430 CanAm engine. Also, the 427 Ford overhead "cammer" engine was a real beast as well. The type of engine to which you refer did not exist at that time.

And yes, it was expensive.

Wait a minute! I thought this was about old gas, not old gassers If the op is flying 20cc engines then why the need for more than a gallon or 2 mixed at one time? That's all I mix at one time and I use pure gas. I use the old stuff to burn my brush pile.

For my 20/25cc planes, I only mix a half gallon at a time.

EDIT:

I still can't really fathom why there is even a question. Bragging about flying a 500 to 1000 dollar plane on 2 dollars worth of old gas? Reminds me of the guys that brag about how little oil they use in their two stroke mix. But then, I guess there are people that actually do play "Russian Roulette".

That's a big argument all the time on the gas boat and 5th scale gas car/truck forums. Which gas/oil/oil mix is best for a certain motor lol. And most are running $600 - $1800 full mod engines.
