Setup: 40 miles on my trip OD @ 60 mpg (totally normal on my ride home commute: +1000' in total elevation - I can easly bring that to 68 MPG total with the round trip)
Wife takes it on the weekend to go to the grocery store
I get in the car this morning:
- AC is ON
- Front Defroster is ON
- AND 49.5 miles on the OD at
50 mpg. . . . ARGH
She drives less than 10 miles and TANKS the mileage. Was she drag racing Pruises in the parking lot??
I was only able to get it back to 59 MPG this morning with a total of 90 miles.
I think my only solution to these driving antics is to buy her her own hybrid

maybe a 2006 HCH
p.s. My overall tank mileage is still above 66. I'm confident I can still eke out 1000 miles on this tank, but I gotta keep her out of the driver's seat.
