View Full Version : Real world 100 series MPG?

Just curious what folks are getting for real world mpg in their 100 series rig, both stock and modified, city and highway?

I've been borrowing the in-laws 2004 4Runner with the 2UZ and I am loving the engine and fuel mileage compared to the LX :) - I know the 4Runner is probably lighter than a Cruiser so the same engine in a 100 series will be working harder and fuel economy and seat-of-the pants power feel will suffer. But dang if it isn't nice to get 18-20 mpg on the highway, with power to go up the hills :hill:

Not a 100, but the 4.7L in my Tundra gets around 15-16. Best is just over 17.

Solid 16 - 17 driving reasonable. 12 if I drive it hard. Got 18 going down to Salida a couple of weeks ago an even better 20 from Salida back to town - wind must have been at my back the whole way.

A little surprised you're getting ~20 with a V8 4Runner. Our 1GR-FE 4Runner averaged about 20MPG in mixed driving. It was a harder working V6 but more importantly had a 2WD mode that made a noticeable difference in power and mileage over A4WD. The 2UZ 4Runner does not have 2WD.

I can't comment on the 100 series much. But my experience with the 4th Gen 4runners, if you believe the MPG dash display, was low 20's with the V8 and mid 20's with the V6. All 4x4. I drove many of them while at the dealer.

Truck computer said 20 mpg...When I calculated out it was closer to 19 but still. One tank of gas from Moab home, with plenty to spare was :cool:

I was trying to get the best mpg I could to see what it could do but I wasn't grandma driving it either.

Overall I would say a solid 18mpg on the highway would be the expectation. Once the :Princess: started driving it around town though, the mpg dropped like a rock...Lead footed she must be :hill:

It would appear that tossing a brick on the chassis though definitely affects the gas mileage :( - maybe the answer still is to supercharge the 80 and get the extra power and just accept the crappy mpg

That's my plan. Its really hard to trade to a new vehicle to save money regardless of MPG. The cheapest vehicle to own is typically the one already in your driveway. If you love the 80 then keep it. If the 4Runner puts a bigger smile on your face go that way. You'll get better MPG but not enough to offset the purchase.

I had a 03 4runner V8 and averaged 18-20 with a 2.5 lift and 32" MT's. I opened up the exhaust a little too. My '99 100 hits about 15-17 with 18" rims/tires from a '07 Tundra. Planning on an exhaust and K&N soon. Open "in" open "out" seems to help the most.

11mpg. With lots of armor pulling the pop up trailer at 75mph
16mpg. With lots of armor driving 70mph

Truck is re-geared to 4.88 33's 2.5" lift, usually hauling a bunch of tools.

Not going the 4Runner route...It is ok and makes a great long distance commuter it would appear, but overall it is a little small for my liking and needs for a family 4-wheeler...

But I really like the 2UZ in what I've been driving and figured I might like it just as much in a 100 series :) - just too bad the extra heft of the 100 series over a 4Runner results in a pretty significant penalty...I figured as much but I was hopeful.

It is interesting how varied folks' reported mpg figures are though...With the 80 they seem to pretty much be 10-12 loaded up, 12-14 stock.

I won't say I love my 80...It is getting older and despite being near bullet proof, sometimes I think having a more posh ride would be nice :hill: - Unfortunately for me I'm seeing less and less off road time and more and more long drives to soccer tournaments and 10-12 mpg is painful

I don't know if the later years of the 80 do better on fuel or I just got the right touch on the gas pedal. But I still get 12 in town and 14 on the HWY built. Stock I'd get up to 18 on the HWY. Towing the camper home this past weekend I got almost 11.

One of the big variables people never mention is what speed they drive. I stay at 75 on the interstate. Pushing it 80 will drop my MPG a mile or two. Living where I do my truck does not see much more than 70 that often.

My 17 mpg was driving Hwy 285 at 55 out to Buena Vista and back.

Interesting...Both my LX and the 80 are 1997 years.

In town, with a light foot, I "might" eek out 12mpg in the LX. On the highway, I might eek out 14 on a good day that doesn't involve a lot of hills.

I don't drive the 80 much but in town it might eek out 14mpg...Highway I think the best I saw was a drive to Steamboat and back where I got maybe 16mpg, coming back where it was mostly downhill :hill:. I imagine if we lived in the flatlands we could get better.

MPH wise, I typically drive within +5 of the speed limit. I know at 65mph gas mileage will be better than at 75mph...But drive that slow in places and people will try to run you over.

I think you should keep your 80 for a long time because that engine seems to running very efficient :thumb:

I must have less air resistance with all my high altitude driving :lmao:

I've also found that occasionally the mpg will be oddly high or low. (I got 18 once in my built up 60 driving from Bryce To Zion. It never happened again.) I write it off to either a headwind or tailwind. For that reason I put little value in any reported achievement based on a single trip.

10-12 All day, every day. Slee'd, Geared, 285s Drawers, Fridge, usually 4 peeps, fully loaded at ~7200lbs. Last long road trip I was on I averaged 16 doing ~80 most of the way to Vegas.

I agree there. I will say my 18 in stock form was not an isolated event. Nor is my 14 now built. During our trip to Myrtle beach last summer I watched it real close. 13.5 rough overall average from memory. I calculated it each tank but never did the math for the overall. Best was 14.2 lowest just over 13. over a 4400 mile trip at interstate speeds.

17 MPG tops.

It's an old thread, but I'll throw in my numbers. This is for a '99 on OME 866s and 285/75/16 tires using 6% as compensation for the tires. The roof rack was three yakima bars, two bike trays, ski holders (rotated horizontally) and a fairing.

12 mpg - with roof rack and towing 5k pounds (uhaul auto hauler with car on it)
13 mpg - mixed driving with the roof rack
14 mpg - highway with roof rack
14-15 mpg - mixed without roof rack
17 mpg - max I've seen, all highway without the roof rack

I changed the o2 sensors and cleaned the MAF. The following numbers are corrected for my 34" Toyo's

Built vehicle with front/rear bumpers, winch, sliders, dual batts, Slee skid plate system, ARB Drawers and about 300 lbs of gear in the ARB Drawers. The 34" Toyo tires are about 11lbs a piece heavier than say a BFG AT KO

Without the roof rack, found out the full sized one form my RTT and Gas cans subtracts about 1.5MPG. I decided to put it on only when I need it

Also, Mid grade fuel

in city 12.6 to 13.2

Highway flat (between denver and springs) and between 55-70 MPH - 16-17MPH

Highway flat (between denver and springs) and between 70-90 MPH - 14-16 MPG
