Norman Berke:
Driving habits, if you're a person with a heavy foot and does a lot of hard acceleration and drives at 75 and 80 mph on the highway you're not going to get the same kind of fuel economy as someone who accelerates gently and stays in the 55 range.

Norman Berke, Research Associate for STP Research and Development says tire pressure can also really impact your fuel economy.

There have been some studies done that show you can lose 1-2% fuel economy for every pound of pressure you're under inflated. If you're down a few pounds, yeah that starts to add up.

Make sure you're not carrying any excess weight in the car and think about aerodynamics outside the car.

So, having things like roof racks or bike racks those are fine as long as you're using them. But to drive around with them empty you're wasting gas because basically you're interfering with that aerodynamic efficiency of the car.

And what about the windows, up or down?

Windows down has a pretty significant impact on fuel efficiency. There's a pretty good argument that says you're better off having the windows up and the air conditioning running to stay cool, that you're car will be more efficient than driving with the windows down.

There are more fuel efficiency tips on the STP website you can link to it from ours: somethingyoushouldknow.net I'm Mike Carruthers and that's Something You Should Know.
