Kent, I’ve run into exactly this problem at my based airport. When I moved in 2008, they had a mogas tank but the FBO, with the airport management’s blessing, elected to discontinue it. I had been based at a small grass strip before this and we had a small mogas fuel farm for the 8 aircraft based there, coop style. My current base refused to reconsider, even though most of the aircraft could and did use it. The new FBO even protested (and is still trying to hobble us) when we brought our own mogas to the field. The FBO’s recalcitrance will bring up an interesting quandry for them when someone from the very liberal town nearby brings up Pb in the fuel issue. So far it hasn’t happened yet, but it will.
