I often have to drive to different events for work, or to our main office in Boston. My work does pay milage (YAY!) but I still sometimes run into the problem of not having money to put gas into my car to get to that event, becasue the milage is reimbursed to us at a later date. As a result, gas in my car is a big expense for me.

I've got three Frugal Gas Tips for my fellow bloggers. If I get more, I'll add them. Meanwhile, please add your own in the comments! =)

Frugal Gas Tip #1
A good rule to follow of windows -vs- a/c is this: If you are going 40 mph or under, use the windows; it uses up less gas. However, if you are going above 40 mph, use the a/c; traveling at a fast speed with the windows open creates more resistance to the car, and it takes more gas to go that speed than using the a/c would.

Frugal Gas Tip #2
When you pump gas and your tank is full, before removing the pump, tip it upside down to get the last few drops. Over the course of a year, you'll have "found" an extra 1/2 cup of gas. And, you already paid for it!

Frugal Gas Tip #3
Many times people fill their tank, then "top off" to round the money up to the nearest dollar, half dollar or whatever. But when you do this, the gas you are "topping off" with actually gets sucked back into the pump. So, even though you end up rounding up the dollar amount, you aren't actually getting anymore gas. It's like paying for air.
