I got a forward today, one of the "tips and tricks to save gas" type things. But there are two on here that I'd never seen before. I googled and couldn't find anything really...but they sort of make logical sense. Any ideas?
When you're filling up do not squeeze the trigger of the nozzle to a fast
mode. If you look you will see that the trigger has three (3) stages: low,
middle, and high. In slow mode you should be pumping on low speed, thereby
minimizing the vapors that are created while you are pumping. All hoses at
the pump have a vapor return. If you are pumping on the fast rate, some of
the liquid that goes to your tank becomes vapor. Those vapors are being
sucked up and back into the underground storage tank so you're getting less
worth for your money.
One of the most important tips is to fill up when your gas tank is HALF
FULL or HALF EMPTY. The reason for this is, the more gas you have in your
tank the less air occupying its empty space. Gasoline evaporates faster
than you can imagine. Gasoline storage tanks have an internal floating
roof. This roof serves as zero clearance between the gas and the
atmosphere, so it minimizes the evaporation. Unlike service stations, here
where I work, every truck that we load is temperature compensated so that
every gallon is actually the exact amount.
