Good news -- I think! I followed nabe mechanic's instructions to fill
up car, set trip odometer to zero, drive freeway -- I did an hour at
60-80 -- and fill up again.
Bottom line: I got 28 MPG! Incredible.
Mechanic said, however, that in town I might get 15. Which is what
I was getting in the first place -- 13-14. So for what did I spend
$505??
I will burn a tank around town and re****t whether there has been
any improvement.
