Default 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

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

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 started driving it around town though, the mpg dropped like a rock...Lead footed she must be

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.
