I didn’t think it was possible... 23 mpg!

[cyranodabum]

I generally get about 16 mpg because my commute is the worst kind for gas mileage, but this weekend, I managed a surprising 23 mpg! We were on a scout camping trip to Anza-Borrego State Park.

The biggest factor was following our Boy Scout trailer at a slowish 55-60 mph. Coincidentally, I also had set my tire pressures last week at 35 psi, which is higher than I usually have them. During the drives, they were around 39-40 when the tires were heated up. I did have the A/C running (stinky scouts in the truck). I run 285/70 17s.

Fuelly confirmed this morning that this was my best ever (and unlikely to ever be repeated, I think).

Now to figure out how to get a trailer to escort me to and from work everyday.

It's very possible. Now imagine an SR5 with the 245/70/17s also going 65mph... I was getting 25-27MPG consistently and everyone said it was bullshit

Even with the 265/70/17s I can get 25 ez

I got 26 mpg across my state on those stock SR5 tires when I drove home from the dealership @ 65mph!

I hit 20,000 miles and best gas mileage on my trip from western Kentucky to Chicago this past weekend.
24 mpg - Some ECO some Normal - Stock tires 265/65 R18 - Mostly 62 mph.
On the way back home could only get 21 mpg.

Anything is possible if you go slow enough!

I got 23 mpg from Tallahassee to Denver. On the way back I had a trailer and got 19. I bought new tires and now get 18.

What a wasted opportunity! If you would have stayed one foot off the back of the trailer, you could have easily got in the upper 30'S!

Yeah that's the part that's normally impossible for me

23.0 mpg on 2hr straight run down I5 to the BLM Tumey Hills on Monday, 70-74 mpg, ~200# in bed, mostly cc, no traffic, no wind. ~12k on ‘25 TRD OR.

I can consistently get 24+ in warm weather. The biggest killer is when the turbo spools up, if you keep your speed under where it wants to use the turbo you get great MPG.
Winter has been rough though, I'm losing 10-15% efficiency in the cold. Which is normal but watching the average trend down has been the worst. I never cared about efficiency in my old vehicle because it didn't have an mpg display, now I treat it like a score I'm trying to beat

One of the advantages of the hybrid. Coasting in electric mode while the engine is not under moderate engine load. I've gotten good at triggering EV mode quite often. Boosts my mpgs everywhere.

 

[NoSlushbox4Me]

When I do the math after fill ups, it's always lower than what the truck told me it got.

It's very possible, mine goes 23.5 mpg, tire size matters aswell.

I've gotten 24mpg a few times. All depends on conditions, and speed. At 75mph, even on flat ground you're not gonna get there. I achieve it with mostly highway driving on flat ground not interstate as I live out of town.

The reason it seems like manufacturers are inflating their numbers is actually the fault of the EPA. EPA testing is extremely dated and assumes a speed below 60mph for highway driving. It's also on a dyno simulation without any actual real world driving and testing involved. Vehicles are tested under the same conditions though, so mpg estimations are better suited for comparison against other vehicles rather than an expectation.
