Fuel average?

[swim.bike.run]

Ok ladies and gents here goes.

Typically I average 18.6-18.9 on the highway. Ethanol free 89, icon lift, Prinsu rack with a few accessories, consistent tire pressure inflation . Temp this morning on 95 south was 75. Then only difference is I removed my TRD skid plate over the weekend and haven’t reinstalled it yet. Average this morning was 16.6.

Thoughts? Does anyone thing the aerodynamic affects of the skid plate would constitute a 2 mph difference?

I really doubt the skid plate has anything to do with it. Mine gets crappy mileage every winter, I just mark it off to “winter blend “ gas.

check your tire pressure

two things do effect the MPG speed and the air temps ...

winter temps below 40F ave 15 MPG. now in SWFL I have been getting 20MPH sometimes it did show 22 MPH but that was @35-40 MPH.no stop go.

these are like a brick on aerodynamics . go 75MPH plus MPG drops rapidly .

those plates are heavy I do drop them all on my oil changes to inspect for any defect/leaks etc .. looks like they also provide better air flow .

Average winter temp 20-30 degrees and my average miles per gallon is 5.5 to 6.6 how's that for bad gas mileage.

New 2018 TRD off road premium. Stock. Talking strictly highway mileage...if I stay at 60mph On relatively flat highway, I’ll get around 22mpg. I figure that’s pretty good for such a heavy brick with an old school engine and transmission. Once I hit the hills and start driving 70-75mph, it obviously drops, but I’ll still get around 19mpg.

Take it out of 4lo.

Two weeks ago I did a 3,500 mile trip from Chicago area to West Yellowstone, MT. I had the 4runner in and out of 4wd, depending on road conditions, and drove at speeds anywhere from 45 mph to 80 mph, depending on road conditions. Temps were anywhere from -18 F in West Yellowstone to around 40 F in the plains on the way back. I averaged anywhere from around the high 18 mpgs to the low 23 mpgs. The lowest mileage was when driving 75 mph or greater and the best was the run from Jackson Hole to West Yellowstone and then to Bozeman.

My rock sliders were filled with snow/ice for a lot of the trip, as it was cold enough that the snow would not melt and dislodge.

On the way back, I monitored my speed better and was getting better mileage when the speed was kept under 70 mph. However, that is not always feasible on the highway.

I have to say that I was generally pleased with the mileage. I noted little or no difference in mileage between 87 and 91 Octane

3" lift with 295/70/16 ridge grapplers, 50/50 local highway driving, 14.5 mpg avg for me in the winter running regular 87 which is what our trucks are designed to run. We'll see what summer gas brings. Is what it is though, doesn't bother me at all. I didn't buy it and lift it expecting to get good gas mileage.

Wish it was just being in 4WD lo

There's something legitimately wrong if you're not breaking 7 MPG.

I don't know you so I can't account for or question your driving style, but the worst mileage I've ever gotten on a highway was during a trip in 2015. I was driving into a quartering 25 mph headwind with gusts to 40. It was so bad I couldn't even engage the cruise control to hold 60. It would immediately downshift to hold speed. I had to fill up again after only 130 miles or so because I was worried about the wide open spaces I was driving through, and even then it said I was still getting 12.5. Even with all the crap and weight I have hanging off mine it still gets 14+ at 75 mph. Either you drive with a very heavy foot or there is something wrong with your 4R. Cold and winter gas will affect it but not that much.
