Maybe someone who has been down this road can help me out.
Ok, so I'm just starting to research running Mogas in our 6.
We've got an experimental O-320 in the bird and from what I'm reading, with an experimental aircraft/engine there is no STC needed?
Is this correct?
Not to hijack, but to get the fuel to your plane you need a transfer tank. I just found this one that is certified for gas. Most are not. Does anyone have any info on this or another source? My idea is to get two of the tanks and put them on a small trailer. Any ideas?

With the price of 100Ll.com dropping like a Led Zeppelin, it may be false economics to use auto fuel.
When premium, no ethanol mogas is just over $2/gallon cheaper than 100LL, I'm not sure I understand your point. The delta, at least around here, is larger than it's ever been ($2.15/gal vs. $4.19/gal).
That is what I hope to avoid. I have that many 5g tanks, but I wanted something that I can just pull to the station, then back to my hangar - or house. I hope to be flying this spring-summer and plan to use auto fuel when I can.
I plan to put it on a cheap homedepot or HF trailer. I figure I can get the whole thing set up for 100g, trailer, pump, and filter, for about $1400. It will take a while to pay for itself, but the convenience is worth the cost to me. Having an emergency supply of fuel is a bonus.

Our local airport does not allow storing more than 5 gal in hangars, exclusive of the airplane. And most states have rules about transporting more than a certain amount of gas on publc highways.
edit. We have the 'empty counts as full' rule, too.
For starters, you need to know what the compression ratio is on your engine.
Any ratio below 8:5 to 1 appears to do well for people running mogas.
A cool running fuel system is required to keep your vapor lock issues in check.
Running 100LL in one tank and mogas in the other is a very good way to test
your system before you go all out on mogas only.
Before you invest in a fuel transport set up, consider 5 gal cans.
Fill up 3 or 4 to top off your tank and store none of the auto fuel in your hangar. You want mogas to be as fresh as it can be and besides as many
have pointed out, storing gas in your hangar may be frowned upon by authorities
Lastly, take advice from people with lots of mogas experience.
You can look forward to a cleaner running engine without lead contamination and deposits on your spark plugs
Hey rockwoodrv9a,
Did you know we have ethanol free MOGAS at the Nampa Airport? Payette also has it at the pump. I used to fly up there and fuel before Nampa brought it in this summer.
Are you guys using mogas only using ethanol free gas? What octane? Our Costco gas here contains ethanol.

$1.83/gal for premium vs. $3.57 for 100LL.
The difference based on 100 hrs/yr at 7.3 gal/HR is $1,270.20.
Buying a trailer, tank, hose, etc., going to the gas station, storing the trailer / tank etc. is not worth that perceived savings to me. I am not commenting on the mogas vs. avgas debate.
I did pull my neighbor's trailer / tank to top it off and have never been so scared of driving anything in my life. If I were to tanker fuel, I would go buy an old small pickup and bolt a tank to its bed, raising the cost even more.
You might look at this option which the Beechcraft folks have used. I don't have any first hand information but this is usually a good source.
