That pickup gets about 18 mpg if I'm nice to it, if I'm really nice I can squeeze 20-21 out of it.
The beauty of that truck is it's simplicity-I can work on it without the need of a library full of manuals, a PC interface, diagnostic software. And the parts...well, it's a Chevy small-block. They're a dime a dozen.
+1, Chevy as well as Ford trucks are really nice, especially the new ones we're having here as midsize diesel utes....
If i'm quite nice with my ute, this is my fuel-mileage along our freeways here
Average 21.5 km per litre = 50.57 miles per US gallon
That was taken when it was still in stock-trim. My fuel mileage now is even higher due to the 1st-stage diesel EFi tuning kit (RaceChip Pro from Germany)
i installed at the commonrail. It also bumped my hp by plus 22% more and my torque by 21% more at my current power settings, which are not maxed out.
In stock-trim, here's the power and torque characteristic of my midsize diesel ute. Mine is utilising the 2006 engine model, which is just a 2nd-generation diesel in 4-straight cylinder configuration. But there is now a new 2012 model engine, and this one is a 3rd-generation diesel commonrail.
Although the net peak power is just plus 120 kW (163 hp)
, the net peak flat pulling-force is 360 Nm (265.83 lb force-ft)
starting from low revs of 1800 rpm to 2800 rpm.
A typical plus 4.0 litre gasoline V6 pickup may produce between 320 Nm to 380 Nm of peak torque depending on the model, but this will be at a high 4000 rpm and usually it doesn't behave as flat as that of a diesel engine. A comparative V6-configured diesel engine, however, even when it's only 3.0-litre, will produce even higher pulling-force of 550 Nm from low 1500 rpm all the way to plus 3000 rpm, which is more than what a bigger gasoline engine can do....
And this is where the fuel mileage plays into role ---- the lower in the revs where the peak torque is located, the better, as one doesn't need to go to high-revs to pull something....
Incidentally, the peak torque is also the region where the engine is working at most efficient, and the diesel engine can provide this even if you ease the pedal from say 2800 rpm down to 1800 rpm, the peak torque is always there....
