We have been driving back and forth to work - cold car, some intown driving. I thought we would see a drop off as opposed to the straight trips to SLC via back of the lake.
Yesterday we filled in gas. we had traveled 588.4 miles. It took 12.54 gallons to top it off. That works out to 46.92 mpg. Not to bad for a car with all stock components. Even if you knocked off 15% of that to speedometer inaccuracies my mileage would still be 39.9 mpg.
I will be doing a little checking on the odometer to see just how close we are. But there is no doubt in my mind that you can improve your mileage with no cost to you just by changing your driving habits. The next project is to see what kind of mileage I can get out of my 2001 Ford Ranger with 4WD, and a 4.0 liter V6 and automatic transmission. Three big handycaps. I am shooting for 30 mpg.
