Does 24.5 MPG sound low for cruising hiway at 75 MPH?

Thats what I got on a 90 mile stretch today according to the onboard computer. Is that low being that Volvo says 26 (its a 1997 T-5 wagon).

No that is good in my book. You got a 9 yr. old car.

I experienced a tad over 32 MPG with two aboard this past week end. I was traveling between 70 and 75 MPH. The air was turned off. This was in a c70 (02) with high pressure turbo and running on REGULAR gas. Try some Bosch platinum single electrode plugs, clean the MAF and your throttle body. Replace your air filter with a premium (NAPA or factory) unit and I'll bet you pick up some MPGs.

Also remember you had a missfire code and it may still be missfiring INTERMITANTLY

I'm getting a constant 23.5 mpg in my 97 850 R and about the same on the 98 V70 GLT. That's a combined highway and city, with a little more highway. Try staying around 65 mph and I bet you can get around 26 or better. I notice my mileage goes down when I cruise at over 70 mph.
