Prius friends,
It's been quite some time since I last posted. It's nice to see some familiar names are still around.
Over the past few months the average MPG on my Prius has been on a slow decline and I'm wondering if anyone has experienced a similar decrease, or has any ideas as to what might be going on.
Purchased new in October of '03, the car has never averaged less than 40 MPG per tank and typically ranges between 42 and 48 MPG, depending on driving conditions, temperature, etc. My average MPG per tankful has now dropped into the high 30's.
Items of note:
When new the MPG display and physical calculations were within +/- 1 gallon; that difference is now +/- 3.
The gas tank filler neck TSB was performed about a year ago.
I'm taking the car in to be checked later this week, but thought I'd look for some comments and advice here first. Anyone?
TIA,
Moo
