Hey Guys,

I am new here and looking for some information. I have a 2005 4 Door Tundra XSP. The reason I am here is that since I have gotten this truck the gas milage has absolutely sucked.
13 mpg no matter what I do or type of driving. I have searched the forums and found lots of posts on what others were getting but nothing about whether there may be an issue with the vehicle causing the low mpg.
Some other people that I have talked to with 2006 4 door XSP's are getting around 16-18mpg. Is there an issue with the '05s that causes the fuel economy to suck?
I really do not drive with my foot in the floor and I keep up all of the maintenance on my truck but is there anything I can do to bump up my mpg a little bit?

Thanks for the help,
Len

Welcome to the forum. If you do a search here you will find many threads about Tundra fuel mileage. There is quite a range of mileage figures reported. My 05 Tundra AC 4x4 is not great on gas either. Some people claim better mileage that the actual EPA rating but I personaly find this hard to believe because my 05 has NEVER matched it's EPA rating no matter how easy I drive it.. My 05 does no better than about 11 MPG city and 15 or 16 highway, less in winter. About all you can do is just check for the obvious things like sticking brakes and possibly take the truck in to get checked over in case there is a possible problem. Other than that just keeping the tires aired up properly and air filter changed often and using synthetic oil there is not much else you can do. It seems that some trucks of identical year and model will just get better or worse mileage for whatever reason. Yeah I know it sucks, I love my Tundra but am not thrilled with the mileage either.

I get about the same results as Diego, 11-12mpg in the city and 16-17mpg on the highway. I use the scanguage to help determine mileage. I have to say I am pretty heavy with the foot. I could probably do better if I changed my driving habits. But then who wants to drive like my grandparents.:devil:
I am happy with the mpg of my tundra. Oh ya, mine is a 05 DC 4x4 limited.

Thats what I say,but mine is 2wd and gets about 14 in town pretty constant ton the interstate I usually get around 18-19 have broken 21 mpg a couple times about 65 but I usually due about 80 mph.How many miles due You have because what you are getting is about what I was getting until I hit about 15k or so.Like someone else stated not much you can do besides driving like your grampa or buying something else I really think that the intake and exhaust helped me a bit also.And I due run synthectic.

does your XSP have 20s. if so that may be your culprit. lmk if they are the enkie deep sixers, i may be interested in buying them if you want to sell or trade for my oem 17" anthrecite alloys. :tu:

Hey guys thanks for the feedback. I currently have about 25K on the truck and yes it has the 20's. I figured that this might be part of the problem. I was thinking about trying the K&N intake system on the truck. My cousin had a F-150 and when he put the intake system on he saw a couple of MPG gains. With gas over $2.50 a gallon even a 2mpg gain can pay for itself over a few tanks of gas.

...With gas over $2.50 a gallon even a 2mpg gain can pay for itself over a few tanks of gas.

$3.19 a gallon last night here in San Diego at Costco. I get 15 most of the time on my OEM AC - IIRC your DC is quite a bit heavier than the AC (meaning it can haul and tow less too - which probably means nothing as few of us haul or tow close to capacity anyway).
