Start by checking to see exactly what mileage you are getting. Fill the tank and record the odometer reading. Then next time you fill up check to see how many kms. you travelled and how many liters it took. Seeing as you gave the odometer reading in kms you may be wondering what mpg you are getting. liters to imperial gallons, divide liters by 4.546 = imperial gallons. Kms to miles...kms times .621= miles. Then divide gallons into miles and you have MPG. Also under what driving conditions is the vehicle operated under. There are so many things that effect fuel consumption, without all the info it is imossible to advise as to good or bad. Hope this is helpfull to you

I'm not too sure what your mileage was when new, but unless my math is wrong you're still getting about 20mpg which is pretty good.
If you want to increase your mileage, give the vehicle a tune-up (replace plugs, wires, distributor/rotor if the vehicle has one, fuel/oil filters, fluids, check belts for wear, etc.) and check out the tire air level. If it's too low you'll be giving up mileage.

Is your check engine light on ??? Maybe an oxygen sensor is bad ? That would cause your mini van's computer to increase fuel mixture, thereby increasing fuel consumption ! Are your tires properly inflated ?? That too would cause a noticeable increase in fuel consumption ! Make sure your Montana is properly tuned, tires properly inflated and properly balanced and aligned and you should be getting at least the optimum mileage !

I take it since everything is in metric that you're from the Great White North, the land of Wayne Gretzky, Red Green and Geddy Lee. With that said, about 475km divided by 1.60934 equals out to about three hundred miles to a tank of gas. With a 25 gallon fuel tank, you're getting about 11 miles to a gallon, or five kilometers to the liter.
My mom and dad had a Chevy Venture for a period of time, and I'll admit that it sucked gas in town, but did well on the road. Your mileage will always vary depending on your driving habits, but my truck gets better mileage than that and its geared down for plowing snow. My biggest hunch would be to check your oxygen sensors in the exhaust system. The oxygen sensors sense the density of oxygen in the burned fuel, and modifies the fuel mix ratio to optimum settings to ensure efficiency. One of these sensors must be out of whack, and is sending a message to your engine stating that your mix is too lean, meaning it has an abundance of oxygen in the emissions, which then makes it mix the fuel-air mix richer to compensate for that. The result is that you wind up with a lot of your fuel going out your tailpipe. Oxygen sensors aren't cheap, but you will notice that after they are replaced, that you will notice your engine getting better mileage.

If you live in a cold climate is very common the fuel consumption to drop very dramatically when the temperature drops like it is happening right now in many places in the country.

It depends on the weight.Are you hauling around alot of junk?Put some new spark plugs/wires and air filter in there and keep the cargo to a minimum and see what happens.

get a new fuel injector or air filter, or change oil(penzoil platinum) or haul less weight
