Can anyone tell me if this is the average fuel economy for the 5 liter? I have put in a K&N air filter in, a Bakflip F1 tonneau cover and nitrogen in the tires.
I am hope to still get better fuel economy out of the 5 liter.
I have a 2011, exact same specs, minus the K&N. 30000 km and my lifetime average sits right at 14L/100 km.
You will see some much better highway kms anywhere from 10.5-11-5 on some nice flat stretches (no wind of course!), but speeds above 115km/h and wind will kill it.
In town driving sucks it up big time in our trucks, plain and simple. You think you'll be doing real good after a few highway runs, then a few errand days around town, and you're left with the same old average.
There are enough threads and enough posts to confirm an AVERAGE of 13.5 - 14.5 (15-17 mpg) is pretty consistent with MOST everyone similarly spec'd.
Don't baby it looking for a miracle. Enjoy your truck.
