    So I took the truck for its first road trip and noticed the gas mileage was surprisingly low, but maybe I am just not used to it.

    Full tank of gas: 21 Gallons
    Total Miles driven on one tank: 320 (all highway, average 77 mph, 3 total people, no cargo)

    That averages out to be 15.2 MPG.

    This is a brand new truck and I figured to get at least 400 miles out of it. Does this seem low?

    Did you run the tank dry?

    To somewhat accurately figure out miles per gallon: fill the tank, drive until it needs to be filled again, record how many gallons you put in on the second fill-up, then divide the number of miles driven by the volume of fuel put in.

    When my fuel light goes on, I can only put ~17.5 gallons in my tank. The most I've ever put in is just under 17.9 gallons after driving 408 miles (22.8 mpg)

    Good luck going 400 miles between fillups. Mixed city and hwy is 18-19 in my neck of the woods with the 10% Ethanol BS additive. 100% gas and its 20-21mpg

    E10 is definately BS! But I'm still able to average just over 21 with 10% cornbooze.

    If I could run 100% gasoline, I would bet I'd be able to average 23 mpg, and do up to 24-25mpg on all highway road trips.

    I think that's impressive for a truck that will still tow my 6000 lb boat!

    The truck is completely on empty right now (Needle on E). You are saying I should go fill up and see how many actual gallons I drove (320 miles/next fill up to full)?

    Good idea. Still would like to squeeze 400 out of it. Maybe a tonneau cover and less road rage will help.

    Exactly.

    I'm sure your tank still has a good bit of fuel in it. Like I mentioned before, when my low fuel light goes on and the needle is on the E, it still has 3.5 gallons left in it.

    hey philly,

    I just want to add that you shouldnever run the tank lower than the fuel light. The fuel filter is cooled by sitting in the fuel left in the tank, and running it that low can lead topremature burn upof the filter.

    Wow i hope that made sense!

    Did not know that but I appreciate the advice. I do enjoy gambling at casino's but I am pretty sure I grew out of rolling the dice with empty light. I remember the days (high school and college) riding that light out as far as I could, periodically having to call a few buddies to nudge me the nearest station.

    But thats good info to know, thanks!

    I definately wouldn't recommend running the tank dry, but as long as fuel is flowing through the pump, it should be cooled. Is there something special about the tacoma fuel pump that's different than any other vehicle with an in-tank pump?

    I have stated all I know haha. Chris 4x4 would be much better at answering you question and anything more advanced?

    I know if you run the tank dry, you start picking up all the sediments that settle to the bottom of the tank.

    I have all way's contended the same thing. But there are many that would argue that the fuel surrounding the pump does the majority of cooling. I can't prove it either way, but would have to see conclusive testing to be convinced that fuel running through the pump is not capable of doing the job.

    hahaha, I understand. Chris4x4 is a great resource.

    I kind of disagree with you about sucking up sediment from the bottom of the tank if you run the fuel level too low. Think about it, the fuel pick-up always draws from the bottom of the tank, not just when the fuel level is low. If there's junk down there, the pump will suck it up regardless of the level in the tank.

    You have to fill it til the pump clicks. drive X amount of miles. then fill it back up til the pump clicks. now you can divide the miles driven by the gas put back in. For me I just filled up yesterday and was surprised I went 313 miles on 16.0 gallons of gas; 19.6MPG. That was driving it hard for a few days to, using 4wd on wed roads, driving back and forth to work, errands etc. All I have access to is 10% Corn Crap. That shit is a joke. Gas prices are high enough, and to water them down 10%. WTF.
