Dave,

Please check your PM's.

Driving slower or cruise control works as well...

Don't forget to inflate your tires properly!

and get a tune up.

but seriously folks.

If your commute involves a lot of stop-n-go traffic, put your car in neutral or park when stopped, especially at stop lights. You will save quite a bit of fuel by doing that if you have an automatic transmission.

Fill up your tank in the morning.

I never understood how this helped or how topping off your tank hurts... could someone please explain those two to me?

Gasoline expands and contracts with temperature. After the sun goes down the air and the ground temperature cools off and so does the gasoline in the storage tanks at your gas station. The morning is the coolest time so the gasoline is cooler and more dense [weight/volume] at this time. In essence, the gas shrinks in volume. Since you buy the gas by volume [gallon] you get more actual gasoline [weight] when the temperature is lower.

A more simple explanation is that the energy content of gasoline [miles per gallon] is calculated more accurately if done on a weight basis rather than volume. The more weight [pounds or kilograms] of gasoline that you buy for each dollar will increase your mileage per dollar.

Topping off can waste gasoline if it expands and overflows out of the tank into the air or on the ground.

LedJedi - Is this as clear as mud or do you understand?

My favorite way to save gas is to convince someone else to drive to lunch.

I got to telecommute today because of Edouard. Tropical storms save gas!

Topping off your tank doesn't really waste your gas, but you pay the gas station for a little bit of gas that winds up back in their tank. With the newer vapor recovery systems there is a vacuum motor inside the pump that vacuums the gasoline vapor out of the hose/nozzle/tank, and when you overfill your tank the gas that doesn't fit (which you paid for) gets vacuumed back out of your tank and put back into the stations underground tanks.

Is recirculating the fumes a bad thing?
