1995 Volvo 960 fuel mileage
Just wanting to know what mileage people are getting with there volvo 960. I'm getting about 400km a tank with 10 liters to spare, 17 liters per 100km driving like a granny. I have no leaks, no check engine light and the air filter is clean changed the plugs and fuel filter, oil and timing belt. I'm driving highway and small town 60km with next to no stop and go. Can't anyone thing of what might be the cause of the high fuel consumption thanks.

It sounds high to me.
I have a 98 sedan. This year I have been getting 330-350 miles on 16-19 us gals. generally, driving around town, sometimes with aircon. So that's about 13-14 l/100km?
Last road trip this summer we measured 22 mpg, about 11 l/100km, I was disappointed with that and will be interested to see what happens on the next highway trip as we will not be using the aircon.
We tend to use mid grade or premium fuel, the octane numbers are all different wherever you are, but here they are sold as 89 and 93, using a lower grade than that makes the engine drink about 10% more fuel.
My car was in terrible shape a year ago, and I did a lot of work under the hood. You can read the story of everything I fixed in the S90 forum.

On a road trip this weekend I got 24+ mpg(us); later checking found that the rear tires had about 3% difference air pressure so that hurt it slightly. 90% of this trip was highway travel between 60 and 70 mph.
How old is your oxygen sensor? What kind of spark plugs did you use? Can you smell fuel in the exhaust?
I want to install a vacuum gauge so that I can tell which driving conditions use less fuel.

Before I purchase a ScanGauge, I was getting 21/24, after 25/28. Once I drove 537 miles (865 km) on one tank of gas. My guess is that I had less than 15 to go, my low fuel light had just come on. The sweet spot is 63 mpg. This was in my '97 sedan, K&N box filter, Volvo plugs, full synthetic oil.

The gauge teaches one how to get the best fuel mileage by adjusting your driving techniques and by showing you what speeds you get the best mileage at. You really can't dispute 537 miles on one tank of gas...
Just my experience.

Hey rspi I kept my speed down when safe to do so and got 27.5mpg on a tank (90% highway and 2 cold starts)! Thanks again! This car might get 29mpg or more on a nonstop highway run. I better start saving bottles!
I am not sure the K&N filter is a good idea though, especially in light of the fact that some of the white block motors have a problem burning valves.
I think every 100,000 miles the throttle body, idle valve and maf should be cleaned. If the front oxygen sensor is older than 100k, the car tends to run rich and waste fuel.
In the 80s volvo sold a vacuum gauge for the center dash of the car. Apparently all the 700, 900 A pillars are the same so I can use that gauge pod. Lower vacuum roughly correlates to more fuel being used.

I have 97 and city mileage runs around 16 mpg (14.7 L/100) and highway runs 27.5 mpg (8.55 L/100) at 65 mph (105Kph) , 25.5 mpg (9.22L/100) at 70 mph (113 kph) with E10 gas. Speed will kill off your fuel mileage in these cars very quickly.
I did some speed vs mileage tests a few years ago with a calibrated Scan Gauge.
The MPG of each 20 mile run is as follows.
50 mph 35.4 mpg
55 mph 33.9 mpg
60 mph 31.15 mpg
65 mph 28.5 mpg
The test road was Rt 41 between Naples and Miami. I like this road for testing because it is very flat and most of the traffic now takes I-75 across the state.
