Unless this van has trans problems and only 1st and 2nd gear left, there's no way this person got only 4 and 9 MPG their last two fill ups, and the erroneous low numbers skew the data for the vehicle as a whole by several MPG with such a limited number of data points.

Wow, of the two vehicles of this year and model, they both have invalid data, because I'm sure this owner miraculously got double the MPG they were getting on average, as opposed to forgetting to log a fill up and using two tanks full for the 556 miles and 33 MPG they recorded.

Check another year, find more bad data
