Im lucky to pull 320km per tank, do you think something mechaincal is wrong? I admit i have a slightly heavy foot and do around 130km/hr hwy. Even with the heavy foot and speeding i should still higher than 320km/tank right?
No. I'll explain.
I have a '12 DCLB V6 4x4 TRD with almost everything.
When my truck was stock, it averaged around 600km on 60 liters of gas.
[ it turned out to be around 28.5 mpg hwy ]. It stopped being stock after
3000km, and I never looked back, even though I'm a daily driver.
After I leveled it, added around 700 lbs armour, 250 lbs of canopy,
100 lbs of heavier suspension, and 50 lbs of tools I now get around 430 kms combined ( 15 mpg).
If you level your truck, you loose mpg. If you raise your truck, the loss
becomes worse. With aftermarket wheels and large tires, the loss is compounded even more.
Maybe try a few things;
If you have load range "E" on your tires, try and take your tire air pressure
to around 55% of that load rating. People will think I'm nuts, but
it has helped me a lot with my fuel economy. Just make sure the tire
pressure is the same on all wheels.
Are you driving H4? You should be driving consistantly at H2, unless
your off road.
Do you have an manual, or automatic? Your rpms should not go above 2000. Try shifting when you hit the 1400-1800 range for now,
because after 2000 rpms, your truck burning fuel at a rapid rate at 2000
You state your tires are 32.5 inches, so doing a little math I think that's think 285/75/R16, right?
What are your rim/Wheel and tire sizes, if I could ask?
Oh, I forgot, I'm Canadian.
