Gas pumping tips:

Here are a few tips when pumping gas. The first few everyone should know, but I had not thought about the last 1.

1. Fill up your car or truck in the morning when
the temperature is still
cool. Remember that all service stations have
their storage tanks buried
below ground; and the colder the ground, the denser
the gasoline. When it
gets warmer gasoline expands, so if you're fil ling
up in the afternoon or in
the evening, what should be a gallon is not exactly
a gallon. In the
petroleum business, the specific gravity and
temperature of the fuel
(gasoline, diesel, jet fuel, ethanol and other
petroleum products) are
significant. Every truckload that we load is
temperature-compensated so that
the indicated gallonage is actually the amount
pumped. A one-degree rise in
temperature is a big deal for businesses, but
service stations don't have
temperature compensation at their pumps.




2. If a tanker truck is filling the station's tank
at the time you want to
buy gas, do not fill up; most likely dirt and sludge
in the tank is being
stirred up when gas is being delivered, and you
might be transferring that
dirt from the bottom of their tank into your car's
tank.



3. Fill up when your gas tank is half-full (or
half-empty), because the
more gas you have in your tank the less air there is
and gasoline evaporates
rapidly, especially when it's warm. (Gasoline
storage tanks have an
internal floating 'roof' membrane to act as a
barrier between the gas and
the atmosphere, thereby minimizing evaporation.)



4. If you look at the trigger you'll see that it
has three delivery
settings: slow, medium and high. When you're
filling up do not squeeze the
trigger of the nozzle to the high setting. You
should be pumping at the
slow setting, thereby minimizing vapors created
while you are pumping. Hoses
at the pump are corrugated; the corrugations act as
a return path f or vapor
recovery from gas that already has been metered.
If you are pumping at the
high setting, the agitated gasoline contains more
vapor, which is being
sucked back into the underground tank, so you're
getting less gas for your
money. Hope this will help ease your 'pain at the
pump'

Re: Gas pumping tips:

Interesting, but, it would take me too damn long to fill my tank on the slow setting.

Re: Gas pumping tips:

cool

i read somewhere that it's best to fill up at about a quarter tank and fill it up to 3/4. Down to a quarter so you carry less weight, and not less than that b/c then you have to use power to suck the fuel through the lines...
