How far / long had you driven before you started testing? I ask because until the
entire drivetrain is up to stable operating temperature, efficiency will keep climbing, even after the engine/coolant temp has been at operating temp for some time.

I am in the middle of calibrating my scangauge II in between 1st and 2nd fill does this make any big difference on results?

Not really, since the main thing we're looking at in a test is the difference between numbers, not the specific numbers themselves. Even if it turns out your calibration is off, you should still be able to count on the relative readings to do a test.
