 Subject: Gas Mileage - II
IP: Logged
Message:
I just bought a used 00 Dakota Quad Cab w/ the 4.7
auto w/ 29K miles on it. I have only run a couple
of tanks of gas through it, but so far getting
around 15MPG. Another thread was on this subject
but hadn't been posted to in a while so I thought
I would start a new one. Someone said there was a
TSB for a computer upgrade. Does anyone know what
TSB # or the computer s/w or h/w release # is?
And how do I find out which version of the
computer s/w or h/w I have?
TIA,
Jeff

Look on the computer inside the engine bay on the passenger side. There will be a barcoded sticker that says something about an approved software update if you have the new code. 15MPG was the average I was getting with my 2wd QC with the same engine.

Got the same engine/tranny combo and getting 16.5 in mixed, mostly country road driving.
TSB 975 was done for the 4x4 tranny and I gained about .5 miles/gallon over the next 2 tankfuls. Truck currently has about 4200 miles on her.

I own a 2000 QC 4x4 with the 5.9 l and you probably won't believe this but I get 18.5 to 19.0 mpg averaging 70 on the hwy. What may have helped is the flowmaster, an Airaid cold air intake and a throttle body spacer, I also put a tonneau cover over the bed for less wind resistance. Anyway it all seemed to work I average 16.5 around town.

4.7 auto, getting 16-19, probably 17 average. Around 11,000 miles. Computer reads high consistently by 3 mpg, but the 17 average is actual.

Sprocket,
I would love to know how you get an average of 16.5 mpg with your 5.9. What gear ratio do you have? I have a 2000 QC 4x4, w/ 5.9L and 3.92 gears. I get 11-12 around town, and never any better than 16.5 on the highway. I have air intake, 180 stat, headers, larger y-pipe, cat-back, cap, rotor, wires, indexed plugs, and use synthetic oil. Is your truck loaded? I was wondering if the weight difference was that big of a mpg difference. Mine has every 2000 options: items like hitch, power windows, locks, mirrors, seat, big battery, alternator, larger radiator, etc.

I have the 5.9L with the 3.92 gears on a CC and I have been getting 13-15 MPG. A full tank on the highway I can get over 20. Mine has all the options with a K&N Air Filter and Flowmaster cat-back. Maybe your 4x4 option is what is killing your gas mileage.

Troy,
The only power my truck has is under the hood no power windows or anything except A/C. I'm starting to think it's a freak because of the mileage I'm getting. I have no idea what it weighs
or what the gear ratio is. I'm just lucky I guess. Maybe it's in the tonneau cover ???

i ve got a 2000 4x4 with the V6, the only thing i did to it was add a fiberglass cover on the bed, and it got me 5 MPG,
Im from baltimore ,and i drove to texas and was living there for about 5 months, while i was there i got the cover put on , on the drive down the bed was empty with nothing in it but a duffle bag ,on the way back it was loaded with about 700lbs of stuff and i drove on average 10mph faster also, and i still averaged 5mpg more on the way back.
if you are looking for gas mileage that is going to be your number one upgrade on the highway

17 MPG highway 13 town

I own a 02 CC Dak 4x4 4.7 5-speed it since the day I bought it new, I got 18 mpg Highway and as high as 21 city. Honest to god, but thats when i drove it through town like a grandmother. In the first 3 weeks that I've owned it I had 3,000 miles on it. Took a trip to South Carolina week after I bought it. I love this truck (room inside cab, power, and the size of ballz it has under the hood!) Rides 10 times nicer than a GMC Jimmy, I hate that thing!
I wasn't speeding officer I was Qualifiying!

I own a 01 Dakota Sport C/C 4X2 with a 3.9lt engine & auto overdrive and I only get 18 mpg. on the highway. I also own a 1981 GMC 1/2 ton with a 350 4bbl carb that gets over 21 mpg. Can anyone tell me why a new truck does worse then a 23 year old truck does? Is their anything I can do to increase my mileage?

Finally. Somebody else that can't believe the MPG these things get. I get 17 MAX. That's cruise control all the way to work and back. I put a tonneau cover on this week so I hope I get an improvement. Next will be a K&N air filter.
How about this for contrast. I have a 77 Corvette since it was new. Put over $3000 in parts to the engine. I made a "Breather" out of it. Lots of HP and get the same mileage as the DAK. Here's what I can't figure. At 70 MPH the Vette is running about 3500 RPM. The DAK is 2200 RPM. Bigger engine, more RPM And huge carburetor vs Fuel injection

I would like to know why my '98 Dak Ext Cab is getting 13.6 MPG. Its a v6 and i checked the plugs, the fuel filter, new performance air filter, i never run the ac/ or the heat. So am i stupid, what am i missing here. Cause i'd like to know how to get it back to where it was over 2 years ago. When it was doing an average of 18-20.

That's not good mileage for a V6. If you are near 60k replace the O2 sensors, next check plenum and cat for restrictions. I get about 16 back & forth to work and 22 on the highway. And I don't baby it. Did you drop the fuel tank to check the fuel filter?
