+1 for stocking up on storage fuel when the prices drop, but then you have to spend money on stuff to make it last in storage.
Everything I own that is a small motor and runs on gasoline either does not run at all right now, or runs like shit. I gave up on gas powered chainsaws a while back, have a gas powered Echo hedge trimmer that is like a workout at the gym to start, and it was supposedly high quality.
I recently got a gas powered post hole auger. It ran when brand spankin new, now on it's second tank of fuel, hard as hell to start and keep running. Chipper - down, generator, down, gas powered chainsaw - runs briefly on starting fluid, then dies. Gas powered roto-tiller. Same story, runs on ether, dies on gas.
The only thing that I can go with to make my van get the actual factory specification fuel economy is to run super and fuel system additive.
