It would certainly be nice if this was just a calibration by the Scanguage to be more accurate but a drop of 20-30mpg just seems like a lot.
Time will tell though and I'm anxious to see what happens at my next fill up.
As for the figures that azrael suggested noting, I'll be sure to copy those down and compare what the Scanguage reports against the trip odo and gallons used at fill up.
Thanks for the replies,
Jeff
