Dude... I'm using mogas because I'm using a MO-engine. I've driven cars
at over 5000 ft (Lake Tahoe.. 9000 ft) MSL.. and in temps over 100* F...
and alcohol wont hurt MY engine because the seals in it and the fuel
system are DESIGNED to use motor gas in all of its domestic
forumulations. I think some of those "absolutes" you are listing are
overkill.

I will be using fuel injected engine with an automotive fuel rail
regulated at 40 PSI over upper deck pressure..through a recirculating
fuel circut with firesleeved hoses. I don't think vapor lock is gonna be
the issue here. I'm just planning on using 100LL because I dont want to
land on a 2000 ft sod strip 40 miles from the nearest town of over 50,000
people. I'm into flying to travel to where the people are


So? You've a different set of commandments. I just related *mine*. :^)

Rich S.

1. Never use mogas from an unfamiliar source.

At an airport? That's crazy. From a car gas station? Absolutely.

2. Always test for alcohol.

Good idea, if you don't know the source.

3. Never use mogas above 5,000' density altitude.

Nonsense.

4. Always check for water.

Absolutely. Same with avgas.

5. Never use mogas above 80° F.

That's ridiculous.

Our plane has run on mogas (Lycoming O-540) since we bought it in 2002. The
previous owner ran it on mogas for over ten years.

The ONLY time I've EVER had engine trouble has been while operating with 100
LL -- which has far more lead in it than my engine was designed to run on.

I would use car gas if it cost MORE than avgas -- that's how much better my
plane runs on it.

Formulations aside, my big concern with buying mogas from a podunk airport
tank is that the gas could be old and contaminated. This would be due to
the
small number of planes that are actually set up to burn mogas.

That's interesting. Around here, the vast majority of personal planes
(which are predominantly Skyhawks and Cherokees of various flavors) have the
autogas STC.

I'm trying to figure out why anyone still uses 100 LL. It burns less
cleanly, fouls spark plugs -- and costs 50% more. If you have the autogas
STC, and aren't using it, you're just burning hundred dollar bills
needlessly.

Just how much do you think "too much" is?

Pelican's Perch #55:
Lead in the Hogwash

"100LL has a maximum limit of only two grams per gallon, but in reality,
most 100LL has even less. The refineries have learned how to blend a package
that produces approximately 97-octane fuel without the lead, and they add
barely enough to bring that up to 100 plus a few more points so that they
can be sure that their product meets the minimum specification when it is
delivered. Lead is by far the most expensive component of the fuel, so they
save money by doing it that way. When 100/130 was the standard, the mix
limit was four grams of lead per gallon, but in reality the actual blends
were around 2.7, for the same reasons. (There are about 6.0 pounds, or about
2,721 grams in a gallon of 100LL, so the lead is less than 0.0735%, by
weight.)"

Is there an STC for Mogas in an IO-550?

Not enough info, you also need manufacturer and series, though I'd
hazzard a guess at NO...

Here's Petersons listing:
http://www.webworksltd.com/autofuels...edEngines.html

I was looking for info on the Lycoming IO-540-D4A5 for instance. There
is one approved IO model 470 that Continental makes. Otherwise aviation
fuel injection seems to negate mogas usage. As an example Jay is flying
behind a carb'd 540 engine...

The EAA also offers Mogas STC's. Be aware that its also tied to the
airframe on certified planes...

http://www.eaa.org/education/fuel/index.html

The EAA is based on $1 a HP or somesuch...

Ok, fuel is 6 lbs/gallon, and the quote says there is 6 lbs of lead in a gallon...what????

Ahh, grasshopper, read it very carefully, again. There is great truth in
the details, and relationships of the part, and the whole. g

The quote is telling you how much a gallon of 100LL weighs, not how much
lead is in a gallon of 100LL. (Well, technically, the quote also tells you
how much lead is in a gallon of 100LL -- 2 grams -- but that doesn't appear
to be what you're confused about ).
