"That can save you 30-to-90 cents a gallon."
TCEQ's Michael Lindner says you can save up to 5% around town and 30% on the highway. He says every five-miles per hour over 60 is like paying an additional 20-cents a gallon.
And what's in the trunk or the truck bed? Don't pay more for gas to haul stuff you don't need.
"As any trucker will tell you the heavier the load the more gas it takes to haul it."
Dirty air filters can make an engine run less efficient and so can ignoring the yellow "check engine" light can. A bad oxygen sensor can reduce miles per gallon by up to 40%.
And Lindner says forget the drive through lane.
"If you're going to idle for more than 30-seconds at a time, go ahead and just turn off the car. You're going to save yourself gas and therefore money."
And check your tire pressure once a week when the tires are cold.
"Keeping your tires properly inflated reduces friction between the tire and the roadway and can save you up to 12-cents a gallon."
Lindner says some of these steps can save a few cents, but taken together they can have more of an impact on your fuel costs.
