    Ok so I just made the trip from south Texas to southern California in our 2011 access cab 5 lug. I averaged around 21.5 mpgs on flats and 18-19 on the hilly areas. I am running 235/75r15s, a fat bobs lift and around 500lbs total weight including passengers. Does this seem about right? Is there anything else I could do to increase my mpgs for the trip back? I was averaging around 70-75 mph. Also how's everybody else's tacomas done on long trips?

    Keep it at 70 maybe drop to 65 depending on the speed limit. Not too much you can do especially since you have a lift and tires.

    I don't know what else you could do but I was reading some stuff on the Lexus forums and some of the folks there talk about weapon-x (?) CAI and a Sun hyper voltage add on. One guy claimed it did a world of difference on his RX 330...anybody here got any experience with these products?

    The stock intake is cold air. Since you are a first gen search for the deckplate mod. Also grounding kits don't do anything unless you have a bad ground somewhere.

    I average 19.7 combined hwy. I stay at 70mph. No matter what I do with speed I get 19.7.
    Running 31x10.50-15 tires aired to 28psi. Could probably get better MPG if I aired up but I want even wear on the tires.

    Yep tires and lift are killing you, higher rolling resistance and wind resistance.

    My stock I4 stick will get 27+ at 75 and 30+ at 65.

    Are you factoring that the bigger tires have thrown off your odometer by about 7-8% so your 21.5 is really 23 mpg?

    Try jacking the tires up to 44 psi. I've run max pressure for 15+ year with excellent life and without the uneven wear that others warn about.

    Ya tires and lift kill MPG. My 19.7 is with the 11% difference the bigger tires have in revs per mile over stock. Also have done secondary filter mod.

    21 to 24 is the range I usually get on the highway if I set the cruise at 74 on the speedo (70 according to the gps). I have found wind plays a huge role. I ran the same 300 mile round trip 10 times this spring, same driving habits but varying results.

    Thanks for all th input. So I made the trip back to Texas last week. I actually went back loaded down to th max with furniture from the in laws an probably had a total weight including me and my wife of around 750lbs. I'm not sure if it's because the engine is breaking in more or the fact that I maintained between 65-70mph but this time back I averaged 24.7. I'm pretty happy wih that considering the load on the truck and I had a little bit of a lead foot on the hills.
