Check o2 sensors
Has it ever been tuned up ie. Plugs, wires or boots, filters, and injection cleaning? Check the tire pressure, under inflated tires are the #1 cause of poor mileage. Also consider fuel quality and additives that don't contribute to combustion. I hope this helps, Take care.

You're going to have to figure out what's causing the misfire. The car is almost 10 years old, so change the plugs to start with. If you still have a misfire, go to auto zone and have them pull the codes to find out which cylinder is the issue. Then figure out fuel or spark? Coil or injector? Was there a lean code? Check for a vacuum leak. Change the fuel filter and air filter for maintanence. The cruise control may be another issue.

first thing to try is redexe fuel injector cleaner at 1 can to 1/2 tank diesel,then see if you need to anything else.......(start with the cheapest solution first..)

I also have a Chevy Captiva 2L Diesel but with the auto box. The MPG on that one is abysmally bad! I bought it a few weeks ago with just under 30K miles on the clock (2007 model), and it returns around 230 miles on a full tank! That's around 17 MPG and probably on par with a Hummer!!
I was expecting the auto box to be less efficient than the manual of course but not to consume twice as much. Anyone out there with any ideas as to why this could be? I was actually already checking under the car to see if it loses fuel... We live in the suburbs and our trips can be considered a mix of urban and extra urban (they are admittedly on the short side and from a cold winter start; still, this doesn't justify the extremely low MPG). The car seems adequately powered for its weight and considering the small'ish engine and auto box.
Thanks!
SOURCE: Hoe do I fix high fuel consumption in my car?
IN order to improve fuel consumption you must make the engine run more efficiently. here are the most important ways.
typical maintenance. (check the manual)
1. check air in tires
2. oil and oil filter change
3. spark plugs change (TUNE UP)
4. air filter change
you personally can do most of these things. go to local walmart and get most of these items. very easy.
good luck.
