Be VERY careful depending on that feature of Airnav. Most of the places
that list "mogas" don't list a price, have irregular or spotty hours of
attendance, or very well may be mom n pop airparks.

If you plan on using these listed fields, CALL AHEAD and confirm. You very
well may just do better refilling with blue stuff when away from home.

I'm going to be running a Mazda Rotary engine in a Velocity, and the fuel
issue is one that I've looked at several times. I plan on using 100LL when
fueling out.

Make that last idea a *must*, Dave. You don't know what you are getting out
of a strange mogas tank. It may be 100° out and that mogas could've been
sitting in the tank since winter. My commandments read:
1. Never use mogas from an unfamiliar source.
2. Always test for alcohol.
3. Never use mogas above 5,000' density altitude.
4. Always check for water.
5. Never use mogas above 80° F.

Remember - 100 LL can foul a spark plug. Mogas can boil, give you vapor
lock, and stop your engine RFN. Which would you prefer? Would you like fries
with that?
