Highway Fuel Mileage

We'd gotten over 20 MPG on straight highway according to the onboard trip computer.
Since swapping to all terrain tires and doing mixed city driving it's dropped down to 18.5, but fwiw I'd say we're getting pretty decent mileage.

 

I'm getting 16 on the freeway at 80 mph. That's with 285's and a Magnuson. Only about 2,200 on the odometer so far but still pleased. Scaling back the speed to 70-75 markedly improves the mileage.

 

16 on 285s and a blower. That sounds like a huge win tbh.

Out of curiosity what do you get doing 70-75? I'd love to do a magnuson later down the road

 

2020 ORP here. Running stock sized Geolanders, at about 38psi. 0-40 Mobil 1 oil. I get about 19+/- mix open road and town. I can get 22 open road at 55ish, and around 20 at freeway 70ish speeds.

 

Where do you live that you're getting these kinds of mileage lol.
I'm also on stock sized geolandars

 

My last trip was all highway (240 miles), 70-75 MPH and averaged just over 20 MPG

 

I don't think the blower is impacting the mileage at all on the hwy. The hit I'm taking is due to the aftermarket wheels and 285 tires. If I kept it to 70 I'd get about 17.5.

 

With the stock bridgestones, I could get 23 on state highways going 60mph. Now I got 275/70 load range c falkens and get 19 at best. With my mixed mileage, it is about a 3mpg hit. Interstate I get like 15-16 going 77mph

 

Did a longer trip, mainly hwy 115 kph and country roads at 90 kph, got 12.9L/100kms (18mpg). This is the best in months.

I have ‘22 TRD Off Road (9,300 kms Odometer), 285/70 Toyo AT3s C load, Sherpa roof rack, 2.5”/1” lift, RCI skid plates. I usually only do short trips for day to day life, and get 16.5L/100kms (14.2 mpg). I drive granny style as I worry about braking distance due to added weight.

 

I'd like to get something aftermarket when we're ready for new tires, hopefully something lighter than the TRD Pros. I plan on sticking with factory size or go up a size to 275/70. I feel like we get decent mileage for these trucks than people give it credit for, but I just don't want to pay for the premium fuel after adding a blower on a daily lol

 

If I put on a lot of miles I may feel the same. I usually put on less that 10k a year. I pay maybe 600 a year more to run premium.

 

18ish avg on HWY 285/70/R17 KO2's.... 65-80MPH
