Do rising gas prices have your attention? Take charge with PG’s Green Car actions: 8 ways to control your gas-tank expenditures.

Today’s highlight: Drive the speed limit

Uh-oh: sometimes guilty of this! Let’s find out why is this such an impactful action, worth 50 points…. and check it off! After all, even NASCAR is going green!

We all like to get where we’re going as quickly as possible. Less time spent on the road is more time spent at our final destination. Unfortunately driving the usual 5 miles an hour over the speed limit is costing you more than you might think. According to the EPA, gas mileage for most cars decreases rapidly at speeds above 60 miles per hour. For every 5 mph you drive over 60 mph, it’s like paying an additional 24 cents per gallon for gas! That can really add up, especially on long trips. Better fuel economy will also mean fewer greenhouse gas emissions for the miles you drive.

If you drive a hybrid, e.g. this Chevy Volt, you get another point boost!

If you have trouble keeping the same speed, use cruise control. Set it to the speed limit.

You could also employ a back-seat driver to keep an eye on your speed and help you resist the temptation to keep up with others as they zoom past. Use your savings for a latte?
