I will save Skynet from Sarah Connor


« on: October 14, 2009, 02:04:34 PM »

I saw this on the web while reading about increasing fuel economy-

"Buy gas in the morning - gas is sold by volume and expands when warm. So fill the tank up early morning (dawn is the optimum time) when the gas is cold and dense. This way, when it warms up, it expands and you have more than you would have if you bought it warm."

Am I wrong to think this is false?

Aren't the tanks the fuel is kept in below the frost line, making the temp 55ish degrees no matter what time of day it is?

I've heard it was a myth based on the logic you point out. Too lazy to find a link to prove it's a myth though.

Also, when it expands, it has to go somewhere. There has to be some sort of venting.

Not necessarily. Gas (the air in the tank, not the fuel) is compressible...

You may want to research that.  There is definitely a possiblility that cooler gasoline is denser and will therefore may pack a little more punch.

His mind only works in one plane...

temperature and density/volume are definitely related...

but Boyles' law doesn't apply if you're a bubblehead squid. Grin

It does make a slight difference, but is probably more related to the fuel being warmed by a hot vehicle that has been driving around/sun exposure vs a cold vehicle that has just been started/cooled off overnight.

I can change the mileage in G's truck by more than 3 mpg just by driving a little differently (while still moving with the faster traffic).    That's waaaay more than anyone would ever see due to temps in the gas station tanks.    To me this is one of those issues that can so easily be changed much more by other factors that it becomes irrelevant.
