MoGas Long Term Test: 5000 gallons and counting...

Yesterday I noticed that we had pumped more than 5000 gallons of mogas
through the Mighty Grape. This represents something like 60 complete fills
(our plane has four gas tanks, totaling 84 gallons), and around 350 hours of
flight time over the last 2.5 years.

(See: http://alexisparkinn.com/fuel_truck.htm for details on our Jim
Weir-inspired fuel truck, the "Mighty Grape"...)

At an average saving of over $1 per gallon (at the moment, it's more like
$1.25), we have paid for the truck (which we use extensively at the hotel),
the tank & pump installation (which has worked flawlessly from "Day One") --
and put aside over $2500 toward our next overhaul.

Best of all, Atlas (our Lycoming O-540-powered Cherokee Pathfinder) simply
runs best on regular, 87-octane unleaded car gasoline. In fact, the ONLY
time we've had trouble with our new engine has been when we were forced to
buy 100LL avgas, which causes lead-fouling of our spark plugs at the drop of
a hat.

All the worries that people stated, both personally and here in this forum,
have turned out to be entirely baseless. After flying with mogas for the
last 2.5 years, I can unequivocally state the following:

1. Mogas works better in my plane than avgas. Our engine runs noticeably
better on mogas.
2. I have had no problems with contamination of any kind (my pump/tank
installation has a very good filtration system)
3. If we've run across any ethanol, the engine has never burped because of
it.
4. We've run mogas from sea level to 13,500 feet, in temperatures from -15
to +97 degrees Fahrenheit, without problem.

Because of this, I state further that:

1. I would burn mogas in my plane even if it cost MORE than avgas -- it runs
that much better.
2. I will never buy a plane that doesn't have the auto gas STC.

The autogas STC is undoubtedly the best thing that has ever happened to
aircraft owners. If you've got the STC, but aren't using it, you are
literally flushing thousands of dollars down the toilet.
