Re: Gas: Full up or half a tank???

For the garage queens we need to keep the tanks full. Moisture in the air condenses as it cools and so the more air in the gas tank the more water will condense.

Our gas is so junky you need to use stabilizer. I've had gas in a lawn mower (admittedly a less high tech machine) refuse to ignite after three months of outside storage.

Fuel pumps need cooling and that's what the gas in the tank provides.

OCCASIONALLY you need to run it down to nearly empty to help burn off residue, gunk etc. Otherwise it will build up.
