Getting the same
Hi
I have suffered from this since 2001 when I bought my car new in California.I now live in Sweden and it still drinks like crazy. So far NOBODY will attempt to fix it or acnowledge it as a problem. Tire pressure, air filters, you name it nothing helps.
Occasionally it will suddenly behave for a while (like when I needed to change a lambda sensor) then suddenly go back to drinking excessively. My highway miles can get as low as 12l/100km but around town it is 18-20l/100km. I have pretty much given up on this basket case. Chrysler does not seem to care and the standard answer is "no error codes, no problemo". Big help.

Hi, I have a 98 grand voyager and according to the trip computer its doing 18 mpg. I have seen folk on the web say they are getting around 25 or more mpg with the same car. I don't know how they are doing it as I have not been hammering the car. I love the car and really want to keep it I have wanted one for years but I have only used it this week for the commute to work and have already fed it £60 worth of fuel. looking into an lpg conversion to try and save money but I would be greatful if there are any answers or ideas other than those already mentioned. I was also looking into fitting an EGR valve and what was involved in that, to see if that would save cash on fuel. where I live I pay around about £1.02 per litre (not gallon, litre!)of fuel. Fuel in the uk is extortionate.

Hi,
I have a 1999 Grand Voyager that runs on LPG or Petrol. Petrol here (Reading, UK) is £1.06 per litre and Gas is 52.9p, so there is a good saving there. The car shows 13.2mpg (which by all accounts seems bad), which that translates to about 25mpg (in town) financially, which I didn't think was too bad for a 3.3l 7 seater.

I have a 2003 town and country with 3.8. I average 25mpg. but we use US gallons and not liters or Imperial Gallons. I don't go by the approximation gage that tells me how many MPG I get. I go buy the actual miles traveled divided by the actual gallons used. I find there's quite a variance between the gage and reality.
but if you are indeed getting poor gas mileage. go to www.fueleconomy.gov. they have a huge list of things to check besides spark plugs, alignment, oxygen sensors and tire pressure

Thanks for that website its great. I am not convinced yet by converting to gas. I am doing about 10,000 miles a year all extra urban miles so I suppose as I am not doing long runs on the motorway I should expect poor MPG. I have also noticed that the trip computer is a bit hit or miss, so I will monitor my usage and fuel over the coming weeks to work out what I am getting. I live on a hill and getting a proper reading is a nightmare. I went from a distance to empty of 72 miles on the level to zero when parked on the hill at home. Great car though. Love driving it.
