Short-term MPG tests give too much scope for distorting factors (i.e. head and crosswinds, traffic, rain or snow).
A quick snap shot is of VERY limited value.
Do an A-B-A test with each leg about four tankfuls. A shorty test could be distorted by how you fill the tank.
I cannot believe an aerocap failed to improve mileage in a valid test.
