11 city

15 - 16 highway

 

'04 Supercab 4x2, 5.4 3V, 3.55 limited slip rear, stock as a rock save for 1.5" lowering shackles, averaging 18.-something city and highway.

18 highway (unless I go 65+ then it drops to 15)

1999 4.6 V-8, 3.55 gears, 4x2, K&N, Flowmaster Dual exhaust, 265/75/16 Bridgestone Revos. Best mileage was 17 on the highway doing 70, windows down. Average summertime is about 15, my last tank was 14, which included towing my boat for about 100 - 150 miles. Wintertime is total crap, I probably averaged 13 -14 mpg the whole winter... I'm not sure how my Superchips 1715 has affected the mileage.

 

'99 4.6L pretty much stock minus the flowmasters with the duals. Factory size tires (255/70r/16). I average about 14-15 in the city, keep in mind I kind of have a heavy foot. Never actually calculated my highway mileage but I normally set my cruise control at around 80-85 but even at that speed it does great. I don't normally run the a/c because Louisiana has perfect "windows down" weather.

 

02 Screw 4x4 5.4L, stock except drop in filter & catback. Average is 15 mpg. 50% city/50% hwy.

 

4.6 2001 4x4 SC auto with 146000 miles averages about 15 or 17 combined. I drive like an old timer though :santa:

 

Overall average from my 03 4.6 4x4 auto 3.55 265/75r16 stock, except for replacement K&N is 15.4. Truck has 83K on the clock. Best was a tank at 18 worst of 9 (temps well below zero a couple winters ago)

Around town and commuting 16.5 to 17.5. Brand of gas does make a difference. I do not baby it, like to get up and go.

Highway 19.1 at 75 to 80 mph.

 

I don't know and I don't care!

My truck is purely for fun and it's no fun unless you're getting on it a little bit!

If I figured out how bad the gas mileage was I figure I wouldn't have as much fun!

 

You don't drive it enough to do a calculation! Heck, you lose more to evaporation than you burn!
