what are some real world numbers for 2000-2003 s80 volvo gas mileage?

I see epa estimates of 19 city but sellers saying they're getting 27. would like to hear what folks are getting FWD and AWD.

Also what grade fuel are you buying?

thanks much.

 

I'm running a 2005 2.5T FWD, summer mix of city and highway, mostly to and from work, I get about 22 MPG, winter, with using a remote car starter and the reduced fuel economy because of the change over in fuel mix, I run about 18 MPG.

I only use Premium fuel (91+) as that is what the car requires.

If I'm driving a lot of highway I can pull into the 27 - 28 MPG range.

 

2000 S80 2.9 FWD
27-28 hwy (trips) with premium (91/93) slightly less with regular
24/25 normal running around - grade does not seem to matter for this one.

 

2007 V8 AWD on 3000 mile trip avg. right at 25mpg when crising at 70mph (2150 RPM) At avg. 75mph milage dropped to about 22.8 and when went down to 65mph the milage went up to about 27. I suppose if I could restrain myself and just drive at 55 I could get 30mpg.

 

2001 FWD 2.9L

With Plus: 20-25 city/28-34 highway(34 is cruising at 65 mph)

 

2005 2.5T., FWD. 21.1 mpg, mixed driving. 91 Octane.
These cars - like all modern vehicles - will run on any octane level at the pump just fine, thanks to computers constantly monitoring and adjusting the engine. But lower octane fuels will result in a "less efficient" burn process so your economy will decrease.
Case in point;
Last Week I drove my wife's MDX 750 miles on "mid grade"fuel -15.9 mpg. Turned around, came back with premium, 20.1 mpg. Same speeds, no wind to speak off, same load (1 suitcase). This is a 26% increase in fuel economy for a 5% increase in the fuel cost. And I had to stop for gas 1 less time on the way home (1 stop versus 2 stops). I've noticed similar differences before but with the wife and kids along this time it made it easier to be consistant in driving and stopping.

 

Yes, cars will retard your timing with lower grades of fuel, but it's not healthy for the engine if the car was designed to run on hower octane, as most turbos and higher performance vehicles are.

 

Both our Volvo's '03 C70 & '06 S80 get better mileage when we drive sanely. No jackrabbit starts and driving at posted speed limits (ie. 65 mph) helps keep $ in our pockets and not big oil.

 

01 s80 2.9L FWD w/186K running regular 87 octane
27mpg highway (as I reset tracker on long trips) / city ?
23-24 mpg average on tank when I fill up by tracker and by punching #'s

 

What RPM are you getting at various speeds? I have a 2003 S80 2.9 RWD and I am hitting 3k rpm for any speed over 65 minimum. I only get 20mpg on all highway driving.
I like the car, but have to get rid of it if I can't figure out the MPG issue.

 

I have owned lots of Volvos in last 25 years. 700 series 3 of , older S-90 excellent car, 850's 2 of, V50, XC-70, S-80 T6, and others.
Most of them get between 18-22 mpg in winter, 23 to 26 mpg maximum in summer.Thats US gallons I did the conversion.
However what are your driving conditions. All we have is 2 lane country roads. average stop sign every 3 or 4 miles. curves, hills, 50mph (80K) speed limits and some 55mph (90K) roads.
I use premium in all my cars, except my old Ford Super Duty 450 truck 460 motor I use midgrade.

 

Sounds like you rpm to speed is mixed up. at 65 should be about 2300. Maybe it is not shifting into high gear or is it manual?

 

I don't know where that figure came from that ikemm88 posted (hasn't been around for years and years BTW).
Volvos are heavy cars. The engines are designed for fairly decent performance, even the non turbos perform reasonably well.
I've had three, none have seen anywhere near 30 + mpg. And hardley ever 25mpg. Really, I get 18 20 unless I put my foot in it.
You might try a "Stage 1" tune and maximize you efficiency. Expect 22 ish though.

 

75mph milage dropped to about 22.8 and when went down to 65mph the milage went up to about 27. I suppose if I could restrain myself and just drive at 55 I could get 30mpg.

 

I get 30 mpg at 65-70mph in no wind.
27 at 75mph.
19 to 22 mpg city.
99 coasting downhill.
