2.7l @ 18.8 mpg

18.8 average mpg I am getting city/highway commute to work mostly with a/c on .
anything I can do to improve this ? normal ?

ran a couple of tanks with Seafoam to help clean things up. no improvement.
not a leadfoot or a grannie driver . 65mph on highway

1999 ext cab 2.7l , 4x4 manual hubs , auto, 106k miles, 245/75 r16 ( bone stock except for wheels ) no idea about rear gear ratio (how to read off sticker?)

 

Drive a Corolla.

Seriously.

Trucks are not made for MPG, they are made to work.

I think you are getting fine MPG for your described conditions.

And you are even exceeding the EPA estimates, a somewhat rare event.

Its an automatic, therefore that mileage is normal. If it were a manual, you could see 21 mpg. @BartMaster1234 has the same issue I believe.

 

That's about what I get on winter gas w/ 33's and 4.56 manual. 18-20 is pretty standard.

 

Yeah, that seems pretty reasonable.

The best thing you can do for your truck's mpgs is get a daily driver and park you truck. This works best for a truck that's used for offroading or camping or anything on the weekend. It sounds like your truck is your daily so probably not the best idea.

 

thanks for the replies .

my "15 4Runner got 18 , was heavier and 100 more hp albeit newer technology, . that was where my question was founded . I was just curious . not worried about the fuel cost so much

 

I have pretty much the same truck but manual, and I average around 19.5-20

 

another option? Turn off the A/C and get some fresh air. for some reason Toyota messed up the 2.7/3.4 with having the A/C on, sucks the life out of the truck.

I only use it when it's over 85° or really humid.

You could also keep the RPMs under 2k on acceleration, I gained 2-3 mpg this way when I was trying to get lower insurance

 

Mine is getting great fuel mileage. Had it almost two months and haven't put any fuel in it. Of course, it's spent most of that chopped in half in the garage.

But seriously, I DD an old Outback (84 miles a day) and leave my trucks (yes, multiple) set. A F150 is the tow pig and the Tacoma will be the general run around and hunting truck...replacing a 2wd 1990 Ranger.

 

On my 2.7 manual (manual locking hubs) I was getting 21-22mpg in my California commute driving mostly country roads 50-55mph. After swapping Michelin M/S tires (235/75R15) for KO2 (30/9.5R15) the mpg dropped to 19-20mpg. I know the KO2 tire is a bit taller (about 3% speedo change), but it is much softer and increases rolling resistance. Now doing mostly city short trips (shopping) I'm getting 15-16mpg. There might be also a difference in gas chemistry (I use European BP 95oct) that can affect mpg but it is what it is. No comparison to my wife's Nissan Versa Note (CVT) that runs 36mpg on average. Nissan is cute, but I can't load 10ft long lumber in it.

By the way on my 2012 4Runner I'm getting 20mpg city and 23mpg on country roads (still no go for 10ft lumber)

 

Honestly, if you're getting 18 in a 4x4 Tacoma, I'd be happy with that. I'm lucky to get 16mpg out of my 3.4L doublecab 4x4, but my foot is rather heavy and it's an auto.

18 is about the EPA rating anyway (under "ideal" conditions, which no one realistically drives in).

Unless you're a hypermileing grandpa, I wouldn't generally expect much more than that.

I could squeeze 21+ out of my '17 4Runner, but I prefer not to get passed by school buses and bicycles. I typically get 19-20 on the highway, 16 in the city/traffic. 12 if I'm towing my travel trailer.

 

I have the same 99 2.7 and a auto. I got 19 on the highway and that was it. With the auto trans, they paired it with 4.56 gears for a little power. The manuals have various ratios. The code on the door will tell you.
B04A 4.56 bottom right corner.

 

Yes. That’s normal. I get about 15-16 MPG.

 

18-19mpg for mixed driving is actually quite good for the 2.7 auto as in its right where it should be, and not worse.

My 2.4 auto taco gets around 17-18 city, and 21-22 highway. The 3.4 auto 4runners get 15 city and 18-19 highway.

Whether you drive auto vs manual for mpg makes a very significant effect on 2.4, a lesser effect on 2.7, and a not to big a difference on the 3.4. Of course that's generalizing as there are outliers - and I wish I had their vehicle's mechanical makeup.

 

With a 2.7 four cylinder, 5 speed manual, 4WD and 265/70R-16 tires (roughly 29" - 30" tall) I average 21 MPG. I check it every time I fill the tank and sometimes I can get that to 22 MPG. Mixture of city/highway driving and A/C on.

HOWEVER, there's a caveat to that fuel mileage.

That's running non ethanol fuel (100% gasoline)

With the standard 10% ethanol / 90% gasoline blend - the mileage averages 18-19 MPG. From a money viewpoint, I break even. The ethanol blend costs less per gallon. The non-ethanol cost more per gallon and the difference in price and fuel mileage negate the savings. It's a dead draw in terms of price.

Ethanol produces fewer BTU's per gallon than gasoline. When you blend ethanol with gasoline you reduce the total amount of BTU's produced by that gallon of blended fuel compared to a gallon of pure gasoline. Therefore you must burn more of that blended fuel to produce the same amount of power.
In terms of money it doesn't save a penny.

 

What tire pressure are you running? Higher pressure will yield better MPG.

 

My 1999 2.7 gets 16-17 mpg. I’d kill for 19

 

I get right around 19 mpg with my 2004 RC 4X4 2.7. The best mileage I've gotten was on a long trip (1500 miles round trip) with about 750 lbs in the bed running at 80-85 mph. I get 25 doing that and that is at high elevation up and down 7% grades throughout WY, UT and NV. I was using 91 octane back then. I use 87 ethanol free these days and I get the same around town. 19 mpg. Unfortunately, on a long trip finding non-ethanol isn't easy. Ethanol should be banned. It does nothing but decrease mileage, absorb water from the atmosphere and cost us more money. Not to mention everything else that is negative about it.

 

That’s about the same as I got with my previous truck. 2001 4x4 with 2.7 and 5 speed. 265-70-16 tires. Basically a stock rig.

Try driving only downhill with a tail wind. j/k

 

My 2.7 Dog 4 door slow wih gimpomatic gets 18.7-19 mpg all the time

If I do mostly highway I can get 20 mpg

Doing 85mph and the mountains doesn’t help
