Your "at pump" test results could be off by as much as 10%

I ran across and gas station maintenance tech at a QT yesterday. Asked him about their gas pump calibration techniques. He told me something interesting that is worth sharing. They dont have to recalibrate there pumps unless they are off more than + or - 5%. So using the same pump when testing MPG turns out to be more important than i previously thought. FWIW

I found this kind of realated also


I would like to add to this list... Where you fill up makes a huge difference on fuel economy. For instance on my 2003 Saturn VUE, if I fill up at my local Chevron I get the average fuel economy as posted by the EPA (17/23). If I fill up at the local Shell station, I get slightly better MPG (19/25). If however, I fill up at the local quick-mart, I get a whopping 12/15 MPG.

Now I am not saying that everybody should fill up at Shell. But you should do mileage comparisons with different fuel stations to see which is better. Just because you save a few cents on a gallon of gas doesn't mean that you are saving money.
