Its a 3.3L

And it does about 80km to $20 (fuel is 1.29/L here) so thats not good.

What sensors need to be done? O2 is new...

Is there a sensor in the airbox thats maf-like which can increase economy??

 

If a tuneup doesn't fix this then it is your driving style. You have to really pamper these vans toget good mileage. I average somewhere around 11.5L/100KM but I have to actively pay very close attention to my driving at all times. Even slightly aggressive driving and driving over 120KMPH will make the mileage fall off FAST.

 

I was really hoping you would say its a sensor like a coolant temp sensor for the ecu like on my bmw...

I really dislike these vans, its like driving a rolls royce, without the power, or luxury or prestige... but with the same consumption!

 

I own 2007 GC (still same as 2002) for 4 months now and I can confirm fuel consumption in city is terrible.

I have driven around 8k on it and total average is 13.75L/100km or 17.11mpg with somewhere evenly split 50:50 city and highway driving.

City is depending on driving style between 14 to 16 L/100km and Highway depending if you drive 85-100 or 120 is around 9.5 to 11.5 L/100km

Bottom line - this van is nowhere near good fuel economy...

 

No it doesn't, its quite horrible. My summer car is a bmw 318is. I did the spark plugs, cleaned the pcv valve, icv valve, checked and replaced all vacuum hoses, intake hoses, coolant temp sensor for the ecu, maf sensor and O2. Its now down to 5L-6,7L .....

I was hoping that the same math would have some effect on this car, since I don't believe it can be that bad, i just don't buy it...

 

I could cut up a BMW 318is and carry it inside my caravan and still get 18mpg. I average 11.5L/100KM in my van in the city, not sure what you're doing wrong. I get closer to 8l/100km on the highway with the cruise set to 120KMPH. I can't believe your comparing a little 4cyl commuter car to a large van for fuel mileage.

Besides that, show me another vehicle that can carry 8 people AND their luggage. You have unrealistic expectations from a large vehicle. If you require the ultimate MPG then you need a small 4cyl car. These are vans and as such are meant to be useful beyond basic transportation.

 

If i got your level of economy I wouldn't be complaining. Considering its only 3.3L and puts out a measly 160hp, you would expect it do do way better on gas. I had a 3.8L town and country and it was not where near as bad as this thing....

 

Have a shop check the fuel trims. The problem should jump at you then be it the van or your foot. If you want to throw parts at it the upstream O2 sensor would be #1 on my list.

uh... a Minivan is a Soccer Mom's family hauler. Your BMW is a Driver's car. The engineering's are completely different. You are comparing apples to orange.

sit 5 ppl on ur BMW, and haul a small trailer, see how it fair on it's fuel economy.

And you shouldn't use your BMW's driving style when you drive a minivan.
