19.5 on 275/65/18 Ridge Grapplers XL load. Drops to around 18 during the winter.

reset my MPG today before I did my almost entirely highway morning commute. stock 2019 TRD OR, 450 miles on the odo, varying speed highway commute (about half slow moving bumper to bumper, about half around 60 or so), 30 min commute, 20.8 mpg. Leaving the MPG tally running for a week of mixed city and highway driving, getting 16.5 max.

1400 miles on my 2019 SR5. Totally stock, drive like a grandma too. Hand calculated at 18.3 in town kid shuttling and grocery getting.

Yep. Colder air is more dense, which is great for power, but bad for gas mileage.

Also, a lot of areas in the US switch to an oxygenated "winter" blend of gasoline.

Texas generally sells conventional and Minnesota sells oxygenated.

Summer Versus Winter Gasoline Explained | News | Car and Driver

Despite those higher prices, summer gasoline contains about 1.7 percent more energy than winter gasoline. Warmup times aside, that’s why you could measure reduced fuel economy outside the summer months. Winter gasoline varies widely in volatility throughout the season. Refiners constantly adjust their RVP to as high as 15 psi—higher than sea-level atmospheric pressure, which is 14.7 psi—to help the gasoline ignite more easily in colder temperatures. The vapor pressure varies by month, region, and octane. In frigid temperatures, higher-volatility fuel is essential and does not cause the smog effect it would in the summer. Using low-RVP fuel is a nonstarter in freezing weather; the engine won’t turn over or might misfire.

Hey all, new member here with 2019 SR5 Premium. I read through this thread before making my purchase fully expecting less then average MPG's. But I was pleasantly surprised that after my first full tank ~400 miles on 18.3 gallons, I averaged 21.7 mpg's hand calculated.

That's commuting about 65 miles a day 75% highway. On my second week based on the gas gauge and current miles, i'm averaging the same. I do drive sort of like a grandpa though.

17 average in the winter, a bit less in the summer. Super consistent and always 87.

I'm trending for a record tank. Computer is showing 23.4 MPG with about 100 mile range left according to the computer. My average over 37,330 miles is 20.7 MPG. I track it all on Fuelly.com 2015 4x4 Limited.

About 17.5-18mpg which aint bad considering I only have 1k miles on my 2020 and live in cold ass MN. Hoping to be closer to 19-20mpg come spring/summer. 2yrs ago I was driving a 2017 Accord hybrid that got consistent 50mpg so a slight drop from what i'm used to

Man, I don't know what I'm doing wrong, I don't drive aggressively, but on my stock 2020 TRDP I'm only getting 15-16 mpg with mix of about 80% highway driving, 950 miles so far.

stock tires, gobi rack, sliders, I am heavy footed and do 80-85mph on the highway I get 16-17 which sucks bc i'm about to put ko2's on

Hand calculated or on your dash computer? Also, my ‘19 TRDP only got 17.0 in the summer. Last 2 fill ups have been 16.2 with the Midwest winter mix gas. I am a very casual driver and try to keep the “eco” light on.

Both actually. Using the Fuelly app to keep track of it outside the dash computer. Over last 2 fill ups according to Fuelly I got 15.3 mpg.

2012 Limited, 1500-2000 miles so far. Truck says 18.9, I have figured it at up to 22. Love this truck.

Through 8600 miles my overall average is 19.6 mpg and trending upward. Last fill-up was my best tank at 20.94 mpg calculated on fuelly.com.

I drive 5 mph over the posted limit, about a 50/50 mix of city and highway driving, with a fair amount of short trips.

2012 SR5 131k miles.

I get 17.5 figured on the dash computer with 75% suburban and city driving. The wife is pretty heavy on the pedal.
