Is it normal for a 2003 Jimmy with 5000 miles on it to burn 22 liters of gas to go 120 kms on the highway? I believe this works out to about 15 miles per Us gallon.
I questioned GM Canada and was told that I had to wait until there was 5000 kms (3000 miles) before the dealer could do a fuel consumption test. I have had the vehicle back to the dealer twice and all I am told is that there are no stored computer codes, it passes diagnostics and the are no available software updates.
The sticker in the window when I bought the truck stated "25 miles per gallon highway" (in Canada I think the English gallon is used on the sticker, which is about 1.1/4 US gallons). The salesperson said that because I wasn't getting the 3.72 rear end and a two door was lighter than a four door I should expect better than this.
I got a different story a week after I bought the truck and questioned him on the gas mileage. I was then told not to expect more than 20 miles per gallon for our climate.
I was wondering if in fact this truck does have the 3.72 rear end. Is there anyway I can tell this , be it from the VIN or a sticker somewhere inside ?
Any help would be greatly appreciated.
