Gas saving tips...delete if its a repost
Only buy or fill up your car or truck in the early morning when the
ground temperature is still cold. Remember that all service stations
have their storage tanks buried below ground. The colder the ground
the more dense the gasoline. When it gets warmer gasoline expands,
so buying in the afternoon or in the evening....your gallon is not
exactly a gallon. In the petroleum business, the specific gravity and
the temperature of the gasoline, diesel and jet fuel, ethanol and
other petroleum products plays an important role.
A 1-degree rise in temperature is a big deal in this business. But the
service stations do not have temperature compensation at the pumps.
When you're filling up do not squeeze the trigger of the nozzle to the
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 mode, some of the liquid that goes into your tank
becomes vapor. Those vapors are being sucked up and back into the
underground storage tank so you're getting less for your money.
One of the most important tips is to fill up when your gas tank is
HALF FULL. The reason for this is, the more gas you have in your tank
the less air can occupy any 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.
Another reminder: if there is a gasoline truck pumping into the
storage tanks when you stop to buy gas, DO NOT fill up--most likely
the gasoline is being stirred up as the gas is being delivered, and
you might pick up some of the dirt that normally settles on the
bottom. Hope this will help you get the most value for your money.

good stuff. having no exhaust leaks helps too. i just fixed my exhaust header leak and i just got 25 miles to the gallon in city driving. i did 248 miles on 10 gallons. i'm liking my car more and more
