I just received this reply from the MSR folks on using Av Gas 100LL in their stoves:
White gas and kerosene are the best options for our multi-fuel stoves.
Most other fuels are not recommended, especially for consistent use, as
they tend to have additives that clog the stove more frequently and may
have adverse health risks. We state that some of our stoves can burn
these fuels (and design them to make this possible) so that someone
traveling to a third world country or really anyone in a remote
situation has backup options for fuel. Sometimes people find themselves
in a situation where that is all they can get, so the ability to cook,
melt snow, etc outweighs the health risks of the fuel. We also have
customers who fly in cold climates and are required to carry a stove
aboard their plane, this allows them to use fuel from their plane in an
emergency situation.
AvGas or Aviation fuel is meant for non-jet or non-turbo prop aircraft,
it generally only comes in two grades, 100 and 100LL but also 80/87 in
some places. The LL is for low lead and it has about half the lead of
the standard 100 grade fuel, if the 80/87 grade is available it has the
lowest lead content. However, it does have lead so you should take every
precaution to prevent the fumes from coming into contact with food and
understand that lead can be harmful to your health.
The best stove for occasional AvGas use is the XGK EX. One could use
the Dragon fly but it will clog more rapidly then the XGK. We do not
recommend using the Whisperlite International for burning AVGas.
