One and ONLY gas mileage thread please

6.2L here, tire choice may help improve a little. w/ 35 mts 10-8 or less city if you dont drive around with one toe on the gas pedal, be happy to get 15 highway.. but lets be honest, when youre driving gen 1 6.2l who really cares about your mpg

13 Screw here on 37s.

since September when I went from 35s to 37s I've slowly seen the MPGs drop lol. hit 13.4 today wooo! i tell everyone the samething, the truck is rated in smiles per gallon not miles.

2013 6.2 I see 14gpm and 18 on long trips
Did not buy the best to compete with the Pris... I make new friends at the gas station each week.

Still getting 15 or less after 5 years of driving the beast. 110,000 on the odo and I still smile when I climb aboard.

So,just how do you get that smile off your face....got mine about 3 weeks now and my Jaw hurts from grinning so much....

FWIW
YMMV

Been getting around 13 around town this winter, easy driving. Short trips, warmup a couple minutes in the morning and a steep hill in my daily routine.
87 or 93 octane don't seem to deliver any significant change to mpg.
Took it for a freeway cruise to the beach at 75 with a tailwind (35 miles). Easy lope on the scenic route home. Nice twisty motorcycle roads.
Got 18.9 mpg indicated on a 100 mile trip.
Variables...I've got a few... ;-)
