I'm not knocking it, but is it really possible to get over 31 MPG on my 2002 XC70? I recently bought this car with 74K and had been serviced regularly at Bobby Rahal Volvo in Pitts, PA. I was driving to Pitt airport today with no A/C on and was reading 29-31 MPH at 65MPH. I know that I drove almost 250 miles on what appears to be a half tank of gas or less. The instant readout was showing this milage up and back. Of couse, when I got into town the milage dropped to a bit more than 19.5. For an AWD, this seems to be really great milage. Is this unheard of????? The readout along with the fuel gauge seem to point that way. This is the first long drive it has been on and I simply love this car.
I plan on going to Royal Purple Syn oil this coming weekend too. I am sure this might help the milage a bit more. It's good stuff; used it in many of my cars and they all have run better after changing to Royal Purple. Eight bucks a quart, it should do something, eh?

 

Instantaneous goes up and down a lot. That doesn't seem absurd.

 

Btw, I tried to write more but couldn't get the post to go through.

 

That is a little on the high side of normal, but not out of the question. We get 29 on the highway with our 2001 from time to time.

 

I have a 04 XC70 AWD that is getting 26.5 average. I only use 93 octane and only do the speed limit 55 and 50 MPH on my 20 mile commute to and from work.
