The wild swings from over 30 to under 20 makes me wonder about the accuracy. Also, some use the instant MPG meter on some cars to claim high numbers while neglecting time of low MPG so I had to ask.

When using the fill method, are you using the same pump and location of the car gets constant fills? Using the gas gauge can be inaccurate however MB seems to have them calibrated pretty well.
