More Bang For Your Fueling Buck
Getting the most from gas station pumps
|
With prices rising, Shane Banquer, a helicopter pilot who has been in
the petroleum industry for 31 years, has offered some tricks on how to
get more of your money's worth for every gallon. Thanks to Eric Dufour
for sharing the information.
- Only buy or fill up your car or truck in the early morning when
the ground temperature is still cold since storage storage tanks are
buried below ground and colder makes for denser gasoline. The
difference is likely pretty small since the ground temperature
doesn't change nearly as much as the air temperature.
Shane reports that a 1-degree rise in temperature makes a noticable
difference and that service stations do not have temperature
compensation at the pumps.
- When filling, don't pump at the highest rates since you will be
getting some vapors instead of all liquid. Most triggers have three
(3) stages: low, middle, and high. Low mode minimizes vapor
formation. Also, all pump hoses have a vapor return.
- Keep your tank full to reduce the air space and therefore
evaporation. Don't let it get less than half full. Gasoline storage
tanks have an internal floating roof to reduce this evaporation but
obviously our cars and paramotors don't.
- 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.
