...I read somewhere that adding a small measure of Acetone to your gasoline greatly increases economy. No idea if it's true.
Nope... Acetone, HHO, 'electronic stabilizers'... it's all snake oil and urban legends. If it really worked, everyone (including car and gas companies) would be all over it.
Acetone can actually clean injectors/carburetors/valves a bit, but aside from that it generally just eats up some plastics and rubbers.
As for the CO2 couplets you got your hands on... I'd recommend buying a crosman 2240 or 1077
I love my 2240, and with a suppressor it's incredibly quiet for how powerful it is.
