    Forever sideways and smiling :D
    Been averaging low 15mpg's since I bought my truck in December. It's been between mid 40s-low 60s this week in Omaha and my Ultraguage is pegging 19.3mpg (which is +/- .5mpg for me) 100mi into this tank so far...booya!

    Can get 20 mpg during warmer temps, mixed driving, driving an economical way. No way to get near that value during winter.

    Yep, I also lost almost 5 MPG to the winter weather/gas! I was getting 21.9 in the summer, but it went down to 17.1 with the cold and snow.

    I've been tracking my mileage since November with Gas Cubby , I'm averaging 18.5 MPG , DCLB 4x4 , rural driving , no highway and some 4x4 in snow during that time .

    I am also on 265/70/17 Hankook MT's .

    All in all , I'm OK with my fuel economy .

    I am hoping for the same thing! Better gas mileage with warmer weather so I can laugh and point to the guys with the full size Dodge Hemi's while they are at the gas pump paying $60 to $80 for a fill up and me and my Tacoma paying $30 to $40 to fill up!
    Honest!
    I will stand there and point and laugh at them ! ha ha ha ha !

    Its true! Nice Guys Finish Last! (stop being a nice guy and watch how people will want to please you and respect you)

    Why the heck do you get better fuel economy in warmer temperatures? I don't get it.... That's good news to me and my 15mpg, though....

    #1 The engine comes to normal operation temperature more quickly (cold engine uses more gas)
    #2 You don't have the heater running, heat from the heater core takes away engine heat
    #3 Winter mix of gasoline, more oxy, chemicals that keep fuel from freezing up and chemicals so fuel doen't spoil, go bad, varnish.
    #4 Motor oil, trans, pwr steer, axle fluids are thinner, better flow with warmer weather, so these systems, gears don't have to work as hard
    #5 Better tire traction, the tires don't have to fight finding traction thru snow (the rubber is softer on the tires, compare it to riding on solid hard tires in the winter to soft tires that give , move and flex in warmer temps, tires are engineered and designed for warm weather)

    All sound like valid points. Thanks. I guess I've never really given it much thought... This makes me more excited for summer..

    ^^ Plus, if you have the A/C linked defroster, that is sucking more gas. And of course, 4x4 in the snow really takes a toll on MPG's.

    yea mines been kicking ass on winter gas here in ca but always notice an increase in summer ... cause currently i get 22-23 unloaded .... so if that goes up my big ass t100 will offically get better mileage than my 99 mazda xcab 4cyl that preceded it.
