I didn't want to break the flow for the other recent thread, since they all looked like 3.4L trucks. But I would like to hear how other 2.7L trucks are doing.

Lately, I've been getting about 330 miles for 15 gallons fills (~22 mpg), for mixed city/hwy driving. This hasnt changed much from stock days (I have headers, intake elbow mod, electric fan, camper shell and roof racks, all synthetic fluids and well serviced).

I can usually get 400 plus miles to the tank on road trips if I go light on the pedals (up to 24-26 mpg) - I'm the ˟˟˟˟ up d!ckhead that sets cruise control one mph less than the next slowest guy around, so that I dont even have to thing about passing.

How are you guys (all three of you 2.7 owners) doing?

My 2.7, 01, Tacoma extended cab, auto fluctuates depending on how I drive in these WV mountains. 18-20 in these hills and off road combined and on the highway(freeway) 21-23 depending on mountains or flats. Speed limit here is 70 and most other states are 65. I just set the cruise at the speed limit.

For comparison, I have a 1999 4Runner 4WD with the 2.7L 4cyl and a 5spd manual trans. To date, I have yet to hit 260 miles before my low fuel warning light comes on. The few times I calculated my actual gas mileage, it was a depressing 17 mpg or slightly above. I keep getting CEL for the TPS, and then just having AutoZone reset it - because I don't want to disassemble the TB to be able to access the sensor and possibly clean or replace it. Unless there is compelling evidence that this is contributing to my poor mpg...

I am averaging around 16-18 MPG average and thats about 70% highway driving. However, I have about 500#'s of extra weight with bumpers, skids, tires, winch, etc.
And I recently replaced my hi-flow cat with a stocker and my Dynomax muffler with a Walker Quiet Flow.
The mileage isn't bad, in fact I think its pretty darn good considering all the things I've added to slow it down.

It's good to see someone explain that they are hauling extra weight , or bigger tires or lifts or whatever may change the mileage. It seems to me that your gas mileage is great for the extra wight you have on board.You don't state what size tires your running but all of this can and does make a big difference.
I'm hauling around #500 extra too in tools and off road rescue items for when I get stuck 25 miles from anywhere,Lol.
One thing I don't do is fast take offs or stop and starts, Just not my thing, Mike

I get 18-20 with my 98 4runner. My only mods are K&N FIPK, Line-xed bumpers, BFG All-Terrains, and a newly installed Magnaflow muffler. I usually get 240-260 miles to a tank of gas.

I have a 96 4Runner with Auto Trans, 4WD (ok, it's underpowered)
and 255/70/16's. I almost never drive on a freeway or interstate.
I'm on suburban/rural roads almost exclusively. I've never broken 22 mpg.
Usually 21.x mpg when not doing any 4WD. I've had the truck for
only 6K miles, but have computed the mpg for every tank of gas.

Only mods, kind of, are K&N FIPK and a hi-flow cat.

I tracked my mileage over about a 6 month period. Here are the results, not too impressive. The only thing that I will say is that I have all of a 3 mile commute to work that does not involve any freeways. My truck is barely warm when I get to work! I would have to say that for any given tank I drive about 75% city and 25% highway, so that would make a difference.

What do you all think?

In my 4r i usually get around 19. 17 is the worst I've seen, and 23+ is the best. My runner is pretty trim, no roof rack.. I do have taller tires, 235/85/16's which are a little wider than the stock 225/75/15 that i'm geared for, but my mpg nubers are adjusted for that.

Yeah ugh. My commute is 13 miles one way on a 2 lane highway where the speed limit is 70. So usual round trip is around 25 miles everyday. The best I have ever gotten was 22, where as the norm is around 18-19. I drive pretty conservatively too. However here in North Dakota where there is nothing to break the wind Im constantly fighting head on winds and cross winds every stinking day 15-30 mph variable winds almost every day, clear or stormy. Im sure some of you guys know the 4runner with the 2.7 and an auto...not the best combo. There are some days when the wind blows straight up the highway right at me, I have to keep the 4runner locked out of overdrive to maintain 70...that sucks the gas big time.

I have both 265's and 235's for my winter tires. Stock gears are 4.10. I dont notice much difference between the two, its either underpowered or underpowered. I just think the 4runner is alot of weight for the 2.7 and the auto makes it even worse. 235's are one step up from stock, 28" for crying out loud, and one person driving completely unladen and it still cant maintain 70 on a windy day on flat ground! 265's..forget about it. So yeah I've learned not to expect too much for the gas mileage, but then again for the weight the motor is pulling I think it does alright.
