Always fill up on a cold day

The air/fuel mix burns & expands explosivly.

Err, not quite. A "explosive" combustion is called "detonation" or known as "pinking". The controlled burn in an I/C engine is just that - controlled. It is an evenly expanding flame front that eventually (in mS) consumes the available mixture. In a stochiometrically correct system (around 14.3:1 air:fuel, at STP), this would create a symmetrical burn, but most production engines run somewhat richer mixtures because of combustion chamber shape and variable heat transfer issues. So Yah Boo

With LPG its the same I know very acurately what the Falcon does on gas ( also know what I do.... ) I can get an extra 8 litre of gas in during this cold weather tham in summer. Tony

Very interesting! When I was living and working in Phoenix we would see many overflowing gas tanks in the plant parking lot. Fools would fill up in the early morning close to the plant and the heat of the day would expand the gasoline making their tanks drip fuel.

The theory was that filling up in the cooler morning would get more gasoline for the same price. In reality, the temperature of the gasoline in the underground storage tanks changes very little by time of day or season of the year.

How about buying timber during a dry spell, and then selling it again during a wet spell, it should have expanded. 5%?

Quick, what is the number for Mythbusters?

Right up their alley, when they get bored and cannot prove anything, they'll blow the car up for amusement value
