While I really don't have an V90 I have a 96 965. Purchased it in October 93.
For the most part I love the car. Rides like a Lincoln, handles almost as good as my 780.

Anyway I'm getting really bad fuel economy. Even when I stay out of the peddle.
I'm getting about 250 miles out of a full tank approx. 18 gallons.

I know the tank is bigger than that byut my fuel guage (sending unit?) must be messed up. The low fuel idot light comes on and there is usually 3+ gallons
still in her at this point. A fill up to the point where the fuel is about to run out of the filler doesn't send the needle all the way to the full line.

Unfortunatley my communte to work is under ten miles so she is barely getting warm but I still don't think it should be that bad.

On a long this past fall of 1000 miles I was getting about 23m/g,
and I wasn't babying her.

Anybody else experience this. I thought my 780 with the B280 was bad.....
