Hey guys,
Just bought a nice 05 Tacoma(last Toyota pick up I owned was an early 70s Hi-Lux at 18-19 yrs old.Ran the dog poop out of it!)
My '05 Taco has the 2.7 I4 engine.I have to tell ya,I am disappointed in the fuel mileage I am getting. And it's definately not gonna win any drag races either. I see that this truck is "rated" at something like 24/27 mpg? I don't know who's 90 yr old grandpa is driving, but I'm getting an honest 20.5-21.5 out of mine!This is pathetic.That truck oughta get an honest 24-25 mpg anyway.(I don't run mine hard-ie taching 4-5000 rpm between shifts.In fact I've been pretty easy on this truck thus far)
Question!...I have searched this forum. And have seen LC Engineering mentioned quite often,so I checked there site out.
I was thinking maybe a hi-flow cat and muffler combo(Pro-Flow or Flowmaster...FYI,I'm 49 yrs old, I don't need the drone of a loud exhaust ,nor do I care for it at this stage of my life)-AND was going to get a K&N air filter initally,but, now I'm thinking maybe I ought to go for the entire cold air filt/intake assy. Suggestions? REMEMBER...I'm after mileage FIRST and then performance.
Hell, I could've bought a Silverado or a Tundra and got 18 mpg!
Help!
thanks,
RS

They made the Tacoma a little bigger and used the same 2.7 4 banger which worked well in the earlier Tacomas. My belief is that the added weight has hurt the performance/MPG's of the little 4 popper. But if you can throw a few bucks at it. I think you'll at least be satisfied with it.
1.hedder kit
2.high flow cat
3.performance muffler
4.after the warranty is up there are a couple more thing you can do. But if you aren't concerned about the warranty then you can replace the clutch driven fan with a electric one.

yeah you should be getting better, but if it has below 10000 miles or so it needs to break in a little. The 2.7 in the 05 and up tacomas is different from the previous gen 2.7 though. It has slightly more power and additional electronics that are "supposed to increase mpg" My brothers 04 with 5 speed and 4WD gets 24mpg on a consistent basis. Mostly rural country roads. It is completely stock.

I just bought this truck (used obviously)about 3 wks ago.It's got about 24K mi on it. It's in mint shape,I like the truck,but I just thought it oughtta do a little better than what I'm seeing. I DON"T run this truck hard. It's bone stock-as far as I can tell. Although a guy at LC Engr was surprised to hear about the presumably stock exh man on it.This thing has a bent tubular exh manifold/header that collects to the round flange fwd of 1st cat-with a 2nd cat aft and the BIG ole muffler.All run pretty straight back on 2.5 in piping(either 2.25 or 2.5). I just thought with a 21/27 rating I'd surely get a avg 24 or so. Thanks for any input or suggestions guys  , R |

Clean throttle body, make sure air filter is clean, Tire pressure is correct and if any of those need attention correct those litlle tid bits and recheck your mpg over a tank of gas. with that few niles I bet its simple as a low tire or maybe crappy gas....Most the new toys like the higher ocatne, my moms camry will vary 2-3 mpg if she runs the cheap-o-depo gas, and pcs it up if she runs the 92....try some lucas injector clean also, and maybe look at getting the injectors power flushed(Bg pr some other flush) nearly 4 yrs old with that few miles carbon could be an issue...its a simple fix..
take care
Bill

I'd check to make sure your exhaust pipe is no larger than 2.25 especially on the 2.7 engine. 2.5 is too large and the engine is loosing the required backpressure needed. And missippimud has some good pointers as well that are worth checking into. |

Guys,I'm an aircraft maint tech. And I "tried" my hand at automotive mechs at a MB,Porsche,Infiniti dealer while out of comm'l aviation(hated working on cars!). I've tried all the nml ,obvious things that one cks for with this issue-with no help.
This truck,again,is an '05 with 24k miles.This thing should not require any inj cleaning, I run my tires at 35 psi,a/filters clean.
And according to LC Eng,2.5 in exh is std.
I am convinced it's all stock.The prv owner was a female.This truck is STOCK. And gets sub-par mileage!
I guess it's the way it's gonna be. Like I said,had I known...

Are the tires oem size?height?I replaced the oem tires on my truck w/ same numerical size MTR's. New rubber was taller.Seemed like mpg's dropped.Gauges don't show the change in# of turns tires make.Truck seemed slower, less powerful.Speedo reads slower than actual speed.265/75/16 in one company isn't the same as 265/75/16 in another company.I've read the speedos on tacos are not famous for being spot-on.
BTW, I was unhappy w/ mpg's in my used 03 taco.Bolt-on intake/exhaust helped (+3-4 mpg).Follow Hoodlum's advice on recomended upgrades.They work.

I am convinced it's all stock.The prv owner was a female.This truck is STOCK. And gets sub-par mileage! I guess it's the way it's gonna be. Like I said,had I known... I work for TOYOTA and the stock exhaust is 1.75"2wd 2"4wd" The v-6 is 2.25 And ever hear of crappy gas(someone already mentioned this) I had a clogged fuel filter and injector at 28k(bad gas) the throttle body was cleaned at around 34k along with the MAF(mass air flow meter) Not being a smartass but some of us have already been through this and these are known problem areas and when taken care of these areas the results were positive. |

Hood/tacobel...I am positive it's got the stock tires installed. But will double check.
I am also positive it is a stock exhaust system,but will also look in to this. I'm also pretty sure it's NOT 1.75 dia tubing.Big difference between 1.75 and 2-2.25.Generally can't get it wrong measuring it. But will look again.
I don't generally buy my fuel at the "Shells",Exxons,Cheverons"...but I do purchase it from QuikTrip(a large,quality,first class convenience store chain in the midwest area-(ie OK,MS area), and generally run 87 octane reg unleaded.I've had great results with QT fuel.NO problems at all. I tried 91(can't find 93 around here),no change in mileage. I'll try a bottle of that Lucas fuel cleaner,throw a K&N stk a/f on(ain't ready for the c/air intk yet$), and get back with you guys after I dbl check my info provided.
BTW,this thing comes stk with that tubular header-as opposed to a cast iron unit? If not, well,
I suppose this thing has been fooled with.
Thanks for the ideas/info.

Mud tires will get less MPG's than a street tire even if they are the same size tire. The bad gas that I got came from a Exxon station and you most likely have no idea about where the previous owner bought gas. The factory exhausts are actually off-sizes probably metric it's U.S. aftermarket replacements that use these sizes. I used 2.25" on my set-up. Was going 2" but I could almost sleave the 2 pipes together without welding them(not litterally) and I wanted a larger pipe so I used 2.25". Your exhaust manifold does resemble a shorty header but it's cast.

MTR's get less mpg's. I went to 265/75/16's-at least 1 inch taller.After reading Hoodlum's info I'm going to change fuel filter, clean out MAF & T'-body & change plugs & remove-clean-check-reinstall injectors (I would't do it without the OEM Service Manuals). At 75K mi's, taco must be due for this. Cool thing about Toyota Corp.: After I bought set of 3 books from Toyota dealer,they put me in a database.Toyota has sent me every Service Bulletin and Sevice Manual update-FREE! D-C never did that! On wife's '00 Cherokee, never got updates or bullet's even though I bought manuals from dealer.  |

I would def put off doing the injectors. It's an agravating job. I would do everything else on your list first. And if the results aren't positive enough then look into doing the injectors. Here's a company that my friend Gadget(Steve) works for. He's impecable with Tacomas and has been a long time customer of mine.He may have more input on this subject for you. He can also be found on the Customtacos forum. www.urdusa.com/ |

I'll put injectors on 'B' list, thanks. Got done with oil/fluid/filter changes and front brake pads (first time I had to do pads on my yota- I see why yotas are known for good brakes). I found spray-in MAF cleaner. Is this the stuff? Is a Fram fuel filter as good as factory filter or should I go to local yota dealer and get OEM unit? Is there K&N upgrade that improves flow? I checked out Customtacos.com, it's a good site, more slammed trucks. The name says it all. Gadget is a moderator. The tech stuff they had was pretty good. It still amazes me how much info I can get online. Thnks for the tips.

I've talked to the few guys here at work that have the newer tacomas with 2.7's and none of them are getting better than 24 MPG The average seems to be about 22 to 23.
No the Fram filter is not as good as a factory one but it will do the job,for how long I don't know.

;D I cannot believe this!  You get 21+ out of a 4wd. truck & want more?  I don't get it. My wifes '06 Odessey was rated @ 18/22. I have yet to see over 17. Enjoy the truck & have fun. Later... |

I get 22mpg ot of my '06 reg cab 2.7 4x4 with 11k on the odo. .....and that's driving mostly highway at 60-65mph and babying off starts. Don't feel bad, atleast we won't brake anything!

If I couldn't do any better than 17 out of an '06 Odessey, I think I'd have to punt that thing! Shoot, a late model Suburban will do that! And you get all the room/power you can use. I finally cracked 23 mpg on my Taco. 23.4 to be exact. And I didn't really do anything different. :-XI did put a bottle of that Lucas fuel treatment in.Hard to beleive that did it. Ah well, from what I'm reading here, I guess that's as good as it's gonna get.Fuels hit 3.29 for reg unleaded here in Tulsa. It's got me looking at motorcycles!! |

I'm not complaining that I get 19.5mpg in stop&go w/ the A/C blasting. I can get 22-23 on highway and I think it's great for a 4x4 truck. Preventive maint. keeps'em running. Hoodlum pointed out some things I'd overlooked (like cleaning MAF sens.). It still hurts to pay 3.20/gal.! But the $$ we don't spend on repairs (since yota engines seldom break) offsets this. Cost per mile per years of use=yotas still the cheapest vehicles to run (not counting the $$ we spend modifying them).LOL.

im running a 99 taco and am getting horrible mileage,im also running kumho mt's 31's.ive done the fuel filter and full tune-up.ive been told toyota recomends replacing the o2 sensors every100,000 miles...even if check engine light is not on,carbon fowled o2 sensors can contribute to poor mileage by not reading 100% accurate,ill keep you posted as im going to replace mine,but im scared of the price of 2 new 02's from toyota
