JONESBORO-Today we decided to find out just how much of a difference driving with the windows down, or the air condition had on fuel efficiency.
We drove to from Jonesboro to Marked Tree and back several times. The first was with the air conditioner off and the windows rolled down. The second was with the windows up and the air blasting on high. What we found is that either way, the gas mileage was about the same.
Another myth is whether or not turning your car off and on will burn more fuel. Actually it doesn't thanks to modern fuel injection technology. However, in older cars with a carburator this wasn't the case.
The finaly myth is that gas prices are cheaper on Wednesday because it falls in the middle of the week. This too is false, because gas prices fluctuate daily based on markets and the choices of independent station owners.
So now that we've covered the myths, we move on to the truths.
The following is a list of things that will make a big difference in your fuel efficiency.
1. Make sure your tires are properly inflated.
2. Remove excess weight from your car.
3. If you have cruise control, use it, especially on long trips.
4. The biggest fuel saver is driving the speed limit and driving sensibly.
Hopefully all of this will help shut the door on all of the gas-saving myths, and help you drive a little bit cheaper.
