I’ll agree with everyone here, the truck isn’t a fuel miser by any means. I have a 94 4×4 4-door Jimmy, 4.3L automatic and a 3.42 rear axle.

Bob, It depends on how you are coming up with this number. I have a 1999 Jimmy with the 4.3L engine. I also have a trip computer aboard. My average highway/city driving is about 18.5mpg (60% of my commute to work is highway). If I set the reset trip computer before I leave for vacation, I get a number of about 21mpg/highway (This would be at a maximum of 65-70 mph.). I notice, that when I exceed 70 miles per hour, the fuel economy drops drastically. I have also performed a city driving test. In that test, I found that fuel consumption was about, 16.5 miles to the gallon. In short, never trust a salesperson. They will say what you want to hear. You could also increase your highway mileage by using the cruise-control, if your truck has it. Most drivers can’t maintain an even speed, on a long trip. I include myself in that statement. It’s because driver’s tend to pass vehicles to make time. Do this for one week: 1.) Fuel your truck to the full mark. (record the odometer) 2.) Wake-up early, so you have no rush to get to work. 3.) When you drive the truck to work, use moderate acceleration from a stop, and don’t exceed the speed limit. (Meaning, ..don’t try to pass anyone). With any luck, you will have time to pick-up breakfast or a coffee, by the time you get to work. 4.) At the end of the week, fuel-up the truck, and record the miles/Km. 5.) You might find that this truck can come close to the E.P.A. posted consumption rates. My Jimmy is a 4 door 4wd, and I can get close to the posted MPG, when I’m easy on the accelerator. In the summer, with the a/c on, I get about 17 mpg total. The a/c will take away mpg, Big-time. GMdude

The EPA rating is 23 mpg on the highway for 2WD automatic, or 19 mpg for 4WD automatic. Your consumption works out to about 12.8 mpg (US). First off, how did you measure the consumption? Best way is to fill tank until the pump shuts off, reset trip odometer, drive, and then refill tank and calculate from the mileage and the fuel added. Cold temperatures will certainly reduce the gas mileage, and some engines tend to have worse fuel economy at low mileage. Your mileage still seems a bit low, but maybe not unreasonable.. — Robert Hancock Saskatoon, SK, Canada Home Page: http://www.roberthancock.com/

My boys ‘99 Jimmy with the 4.3 gets AVG 16-18 MPG according to the onboard computer, on long (500 miles)trips he gets 23-25 MPG. They never have been a great gas mileage engine. – Hide quoted text — Show quoted text – > 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?

15 sounds right, I know I can kill a tank a week with my Sonoma with the 4.3. Whenever somebody comments, I just say, "It’s a good sized engine with the aerodynamics of a 4000 pound flying bathtub". — Is sex dirty?
