Rocky,
Its called removing outliers.
An outlier is a value that is more than 1 1/2 X IQR from the nearest other data point. You may have over done it a bit.
At least you made the effort to use figures over a long distance. There are way too many on here who quote numbers from topping up their tank after a few short trips.
