I have a 4X4 2000 Frontier with a 3.3L engine, and I am getting only about 17 mpg. Does anybody have any suggestions on how to get better gas milage out of these trucks?
Well, I tried that, and seems to me like its easier to just walk without having to push it. But, 25 miles back and forth to work could take more than just a few mins.Remove the engine and transmission. Push it uphill and coast downhill.
There is no magic. You have a heavy vehicle with lots of drag. Other than good maintenance (e.g. tire pressures, proper oil, good state of tune) and driving habits (e.g. reduce speed) there is not a lot you can do.

I'd expect the opposite (worse gas mileage) from a cold air intake. Cold air intakes make more power because you can provide a denser fuel air mixture to the cylinders. For a given air/fuel mixture that says you are delivering more fuel to the cylinders. Hotter engine operation generally gives higher efficiency.Ive measured up to 25 mpg on the highway, but I maintain my vehicle well. I thinking about getting a cold air intake put in because thats supposed to give you even better milage
Anyone else put on of these in, do they work
I tested my '05 extended cab after it was broken in (1500 miles) and was shocked to find it doing 17 on the highway.
First thing I did was chenge to full synthetic engine oil. After allowing it to run in I changed it again and went to Atlanta. Round trip mileage went to 19 and change. Maybe I'm on to something. So, synthetic rear end oil, B&M Trick Shift in the auto trans, a set of plugs recommended by the Nissan dealer and fat spark plug wires. I also inflated the tires to the maximum pressure cast into the side of the tires. Finally a four wheel alignment and another trip to Atlanta. Round trip mileage was 22.4. So, after all that work it seems like that's the best she'll do. Sure rides nice though.
