Premium mogas has been just fine in my 160 hp engine for over a decade.

To add to Tram's post: I also use plastic cans, because I'm not flying enough to justify setting up a trailer with tanks. If I did, I'm way too cheap to pay $600 for a gas can. :-) I'd pick up a couple of empty drums, paint red bands on them, & that would be that.

I'm with you. Self serve is $4.45 here currently. Mogas is $1.69..

If I put a tank in the truck, it'd have to be something that could come in and out with very little effort. I've got a short bed to be begin with and couldn't live with a fuel tank back there.

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.

I was just thinking about that, but I don't know how my airport management would feel about it.

I'll still be running 1 wing 100LL though, so you'd think it'd keep them happy.

At my airport, the fire department pokes their nose in every 6 months (leased hangars from the county). You're only allowed to have 10 gallons of containers in the hangar, no more, even if they are empty. I did an annual recently where I needed to drain 25 gallons and still had the empty containers in the hangar and I had to go pick them up right away.

Every place is different, but do be careful that you don't spend a lot for a setup that you can't use if you get caught. Also consider what your liability might be if there ever was a fire and you had 50-100 gallons of fuel in your hangar when your lease said no fuel.

Some people that run LOP find 100LL and Mogas run enough differently that they don't like to switch back and forth, so consider that on cross-country trips.

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.

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.

Mike

Alabama used to allow you as many 5 gal containers as you could fill up and get in your truck.

The DOT requires training when the container is over 8 gallons.

Default Mogas STC

Tram,
You do not need a STC if you want to use mogas.
This does not absolve you of your responsibility to make sure that your engine will be happy with mogas.
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.
An injected system is in your favor due to higher fuel pressure and the much lower threshold for the potential onset of vapor lock.

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.

Mogas with or without ethanol works well for hundreds of users.

Price difference is significant, today's price at CCR for 100LL 4.90 vs 2.20 for
91Octane E10. There is almost always a $2 spread and don't think cheap gas is back for good.

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.
A 5 gallon can empties into your tank in less than 1 minute even through a filter/funnel and is easy to lift.

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
