I'd say it's about right. I got 1-2 more than you and mine was brand new and no ext cab. The automatic does take away a lot. I also think they have 3.72 or 4.11 axle ratios. The manual in the Nissan really adds. I'd say the Nissan would lose 3 mpg with an automatic. see my prev post.

I have an 02 GMC Sonoma crew cab 4X4 and I only get 16.8 to 17.2 in the city and about 22 highway with the V6. I donít like to go on the express way, when I get to 60mph I get the 0300 random miss fire. No one has been able to tell me why. The truck runs great but I have to keep resetting the error code. Any suggestions on the random misfire would be great. I have replaced plugs, wire, rotor, cap, distributor, fuel filter, (pump is good), pvc had it tested at two shops and still have the problem.

I have a 2000 S10 with the 2.2, automatic (62K miles), and a truck cap. Around town I get 20mpg and on the highway 24-25 mpg. Very slow vehicle but, I'm not in a hurry anyway. I had a 2000 extended cab with over 90K miles a few years ago (automatic and truck cap). I would get 22-24 mpg on the highway and approx. 17 mpg around town. Traded it in for a 2006 Dodge Caravan.

I have an S10 and the mileage has been getting pretty poor. I did find when I replaced rear brakes, the caliper guide pins were rusted TIGHT. Once I got them freed up and the pads changed my mileage went up a couple mpg. I do want to note a caution, I had to heat with a torch to get them loose and the pin is in a blind hole and shortly after heating, when I started to turn with a wrench, BANG, the pin flew out and shot me in the chest and took my breath away. The lube inside must have expanded a bunch. In looking how these are rear guide pins are designed, I can see many vehicles out there, particularly in midwest, where these pins are stuck and causing brake drag. They have rubber boots on them also be sure they are good when you put back together. Overall GREAT TRUCK though, but I need to disarm it.

Rick, I just got a 98 Sonoma with 183,000 miles, vortec 2.2, auto trans, ext cab. I traded a 2003 Nissan Frontier Ext Cab, 2.4, auto trans and like you I got better gas mileage with the Nissan at 237,000 than I do with the GMC. I have new plugs, K&N air filter, injectors cleaned, the works, so what gives out there!!! any ideas

I have not found anything to help the gas mileage with this thing, new tires, brakes, plugs and wires, filters, synthetic oil, nothing helps and now that we have 10% ethanol in our gas the mileage is even worse, I think the engine is just underpowered in this truck and that causes you to have to rev the engine higher to move the truck.
I've given up and have just accepted that this thing is just a gas hog.
Wish I could give you more help
