Auto Fuel on the road

I bring a an empty 5 gallon gas can and love the looks I get strolling over to the gas pumps with my big red gas can. One guy asked me in a concerned voice, “Did you run out of gas!” I said, “Nope, I came for the hamburgers.”��

Just follow Interstate 10, you can't miss it. I drive by it all the time on the way to the Colorado River. You can charge your Tesla there, too, but you'll be there a looooong time doing so.

I think the key to carrying the "rigid" plastic fuel containers if you insist on doing so is to pre-squeeze them, expelling air/vapor, before you put the cap on. This will leave them under a slight vacuum when on the ground, but when you get to altitude (assuming you are flying at reasonable altitudes) they will return to their normal shape, rather than trying to expand and subsequently becoming a pressure vessel. Of course this is purely hypothetical and YMMV.

I have two older red plastic 6 gallon plastic jugs with a separate vent cap, from my jet skiing days.

I just leave the vent cap not quite screwed down all the way, so the pressure can equalize for inside and outside, while flying.

Screw them shut when filling jugs up, and unscrew when filling plane up. No issues so far, with fumes.

I just leave the gas cans in the hangar, fill with 100LL when I have to, and carry TCP when I think I?m going to have to. We still burn MOGAS most of the time. Life is so much simpler.

The hypothetical case I refer to above was ferrying avgas to an aircraft with a high compression engine on a small island that was running low due to un forecast wind situations. In some parts of the world fuel (avgas/mogas or otherwise) just doesn't magically appear everywhere. Bring on that 1kWh/kg battery so that we don't have to delve into such a discussion in the future.

As we have a non conventional engine, the use of 93 Octane pump gas is attractive.

Benefits include:

1. Cleaner engine.
2. Longer life for plugs.
3. More time between oil changes.
4. No ugly exhaust smudge on the side of the airplane.
5. $2.80/gallon vs. $5.00/gallon.

A 58 gallon tank, with a self contained fuel pump (battery operated) will be used. Just load it in the back of my Explorer. When not in use, it will sit in my garage (or hangar), completely empty.

Wow, a 58 gallon tank will fit in your Explorer. That's impressive.
Wish we had some of that 93 Octane auto gas in my area. Best I've found here is 91 Octane.

Bruce, what is the altitude at your home field? I suspect that the lower octane is due to the altitude that you live at. Higher altitudes you don't need as high of octane for automobiles and for that matter even for aircraft.

My field is at 4550 ft. My hope has been the Rotax 912iS will be happy with 91 octane at these elevations.

My 912ULS has been perfectly happy with 91 octane at 1050 MSL for the past several years. I don't know what the formula is (assuming there IS a formula) to equate 93 AKI at sea level to something else at higher altitudes. I'm almost certain someone here knows, though - there are some really, really smart guys here.
