Brand new Gas Mileage way lower than expected

There are so many factors to MPG especially for city driving so I really only look at MPG for highway trips. If its 85 degrees out and you keep it at 60-65 on the highway you should be able to meet the EPA highway figures. If its 30 degrees out and you are going 75+ mph then good luck getting anywhere close.

 

Put gas in it and the MPG calc will reset.

 

The EPA highway figures are calculated using an average highway speed of 50mph. Going faster will reduce your MPG.

Its also nearly impossible to reproduce the EPA ratings, everyone's driving habits are wildly different. They're meant to be averages, so for everyone thats getting 22MPG, there's someone else getting 15. Unfortunately there are to many variables in driving habits, road conditions, weather, etc to use EPA figures as gospel. I mostly ignore them when buying vehicles.

 

16.8 vs 14.1. I think a lot of people weren't expecting less than 3mpg difference. But here we are.

Exactly. I can get over 19 on the highway with my 5.7 if I stay around 65mph and don't use cruise control. That's with skids, a constant load of 300lb or so in the bed, and 34.8" tires.

 

I have 35in tires and 1.75in lift sitting around 14-15 city and 19-20 hwy. 2900 miles on it. I don’t baby it.

 

2023 Limited 4x4 Crewmax Hybrid. I'm one of those guys looking at the MPG very often; I still do with my 08 SR5. Just came back from 1200 miles round trip from FL-GA; with cruise set at 75mph and I got 20.1MPG. Worth to mention that beside me, there is an additional ~900lbs of passengers & cargo plus head winds. I usually don't use the cruise control when there are hills to climb; hated how the engine revved up. The had cruise control was on the whole time because the turbo kicked in smoothly and steadily when climbing the hills; many times, up to 10psi. With all that said, I think the advertised numbers are achievable.

 

My friend has the 2.7 EB and he can get 29 mpg under 60 mph. But when it goes over that up to highway speed it gets about 18 mpg or so. Same as the 5.0 V8 I had. They all seem to get same gas milage when they are at highway speeds.

It showed 17 mpg for 2022 Tundra. But that's correct about a 3mpg increase from the 2021 Tundra. It's also nature of the twin turbo as I detailed in the F150 lineup. I also had the 5.0 V8 and got 19-20 mph average for the driving I do. I will probably get over 20 mpg with the Tundra. But once it gets up to highway speed they are all the same. I haven't even driven the Tundra yet at all, but the 5.0 V8 was kind of sluggish compared to even the 2.7 EB as far as daily driving. I was just pointing out that all the data is on the Fuelly page. There is no other option for better MPG with full size trucks. There are some more significant situations where the twin turbo can improve MPG dramatically but 80 mph on the highway isn't one of them. It tows over 10k right off the lot. The tacoma and 4 Runner only get 1 mph better. The previous generations V8 Tundra are extremely reliable. I just met someone yesterday that has 500,000 miles on his. Gonna post a pic of it next time I see him. Although I think this Gen 3 is also going to be extremely reliable. And please feel free to post a link to any other full size pickup that's getting better MPG.

 

you do realize that the mpg test is across 5 tests and the avg speed across all those tests is like 48 mph.

 

Someone posted you can reset it to zero mid tank off the steering wheel but mine wont.

 

That's a lot better than I was doing at 400 miles. My average until about 1000 miles was under 13. I'm up to 15.5 now. 95% of my driving is short, in-city jaunts, a bit of idling, and sometimes very heavily loaded.

I predict the mileage will increase substantially when we get back to summer fuel and I'm able to stretch the Tundra's legs more.

 

This pic was taken just now. These will change in real time as more users upload their data. Less than 3mpg difference.

 

there's a heck of a lot more winter blend in there for the gen 3 as well since it launched in winter, only had 1 summer in smaller numbers and then back into winter again

 

dont forget you are missing out on the 2023 tundra's also.

 

Right. Fuelly data on the Tundra page currently stops at 2022. Are ‘23s supposed to get better fuel economy than ‘22s?

 

nope but since mine is 2023 it wont show up in the stats.

and its really funny how if you filter by 3.4L v6 gas it doesnt show any 2022+ tundra's.

only if you select v6 gas or gas/electric

just goes to show, how many people have no clue on the engine size or type it is to properly track a vehicle in fuelly.

 

Fuelly manually adds each engine option or allows users to add their own, so their organization of statistics is a bit of a mess. they don't even list the TRD Pro as a trim, I had to add mine manually

 

This morning it said 17.0 mpg and now showing 16.8 mpg. Not sure why.

I find its a useful tool to see real world mpg in all vehicles. Thats why I provided a link so everyone could access and see if its right for them or not.

I'd suggest doing some research on the vehicle or before making any modifications. As mentioned the 2022 data is available that would give more accurate what to expect. I'm not sure why some people are getting really low mpg while others aren't. Mine is usually above average. I also don't drive many miles a year so mpg isn't as important.

 

i just wish there was a way to filter by year instead of by engine or submodel, etc.

but ive been tracking my vehicles since my 2010 legacy, 2012 tacoma, 2014 4runner (currently mine), 2016 tacoma, 2018 tundra, 2023 tundra (currently wife)

but ive been using a-car app which makes it really easy to input/track.

 

I get it. The 3.5 turbo Ecoboost is the favorite engine for the F150 because of the power. The Tundra 3.5 has even more power. I live in a really flat area. I'm not sure what other people are doing. Maybe just be diffenrt terrain, driving habits, fuel. I was just saying its the nature of the turbos. Might have to dig little deeper to find out if the new Tundra or any 3.5 twin turbo will give you better or worse MPG. I'm fine if it's 19 or so, which I expect for my mixed driving. I also notice long lines of cars at fast food and Starbucks drive throughs where they sit in their cars or trucks with the idling. Increasing tire size, the tread, or lifting can have dramatic change in mpg.

 

and that is were the gas mpg saving should be at with start/stop. that idle time really kills peoples mpg per tank if you sit 10-15 mins idling in a drive thru every day or 3-4 times a week. if you are complaining about piss poor mpg and you are sitting in drive thru's for more than 5 mins, then you shouldnt be complaining about your mpg.

my city driving i could care less about the mpg per tank cause

1. remote starts kill this badly
2. sitting in drive thru's is almost or worse than remote starts


the only mpg i care about is highway trips 100 miles or more 1 way. and with the new tundra the trips the wife will do to go see the grandson about 270 miles 1 way.

 

Yeah, who knows. I might also be disappointed with mine when it gets delivered. It just seems like MPG are all over the place with individual drivers of the exact same engine, vehicle, no matter what kind of truck it is. Of course towing a trailer will get really low mpg. I'm thinking my driving will be close to the rated MPG, but may be wrong. If it gets below 18 mpg I'll be disappointed also. I didn't really like he auto start stop but once again I'm usually just trying to run my vehicle enough every day to keep it charged up.

 

yeah i was really happy we got 18.5 mpg on our trip to bismarck. typically we get 14-15 mpg on that same route and i always do 74 mph except the 2 x 55 zones and 1 x 50 zone and the really stupid 45 zone (that town cop has a hard on for busting speeders, me included)

i only use constant speed cruise control. on the 2018 tundra i had to pause the cruise control since it would kick down 2 gears and screw up the tank avg on trips due to the hills and head winds we always get in ND

 

18.5 is good. With hills and cross winds. That makes a difference. And 4x4. So 19.5 if it was 4x2. That's good.

I obsess about mpg more that I ought to. Just always reset the meter at every fill up. I'll hand calculate for a 1k miles or so to see how accurate the dash meter is.

Especially a truck that can tow over 10k. Compared to other trucks set up to tow that much that's as good as it gets. The GM has the 4 cylender turbo 2.7 that might get a little better mpg but for full size truck this is about as good as it gets. It will be intressing why some people are getting such low mpg and others are getting good mpg.

 

Dips in mileage is when I was pulling a loaded trailer.

I'm on the same page as you. 2500 miles now. Drove 60 miles all highway. 16.9 mpg at 65 MPH. Wondering if there is an adjustment at dealer.

 

The averages change in real time as Fuelly users upload their data.

Currently:
2023: 17.2 (people are probably being gentle with their brand new trucks)
2022: 16.4 settling in to long-term real world average
2021: 14.1 long term real world average for the 5.7

Notice that all 2.5 gen years (2014-2021) have a delta of 0.4 mpg (highest is 14.1; lowest is 13.7). This is the slight variation one would expect with just one engine option.

My guess is that ‘22 and ‘23 will average out the same way. Right now, the delta is 0.8mpg. Although, the turbo v6 trucks can vary more, in my opinion, as your fuel economy can be quite good if you are good at keeping it out of boost, or it can be just as bad as the 5.7 if you have a heavy foot and/or idle for significant periods of time.

The dealer adjustment is trading it in for something with better fuel economy, lol.

Idling kills mpg. Boost kills mpg. If you were driving into a headwind or heavy cross winds, that will kill mpg. Gear hunting to maintain cruise over grades/hills/mountains kills mpg. Check tire pressures, drive conservatively and don’t idle if you want the best mpg, and enjoy your truck.

 

Thanks for your input. I am usually as my wife says driving like and Old man lol. A lot of local drives at 35-45 mph. No rabbit starts or long idling. Don't use auto start. Average between 14.7 and 16.9 on highway doing 60-65. I was expecting much better based on sticker. My 2019 Eco boost Ford was getting 18 Average same driving. Love the truck overall. Really love 1794 Edition. Appreciate the help.

 

Why did you buy a truck if you are concerned about fuel mileage?

You should have bought a Corolla, it gets great gas mileage.

 

Ok, I’m no expert or engineer but I noticed this on my 2020 Tundra and now my 23 Tundra is the same- The accuracy of our dash read out mileage gets all jacked up when we sit at idle.
I can only assume the computer cannot automatically calibrate for idling when you stop.
When idling Fuel is being consumed (much less than at hi way speeds)but miles are not being factored in correctly. So the whole mpg is jacked up after that.

The 2 ways to really know your real mpg is 1) Fill up and get directly to the hi way without stopping. After you burn 1/2 tank or more you should get a fairly accurate reading on your dash. ( I’m getting 19-21 mpg)
2) The old fashioned way - Fill your tank completely, record the mileage . Fill again, record the mileage and gallons it takes to refill then do the math.
