Fuel mileage

15.5mpg city.. dont drive hwy much so not really sure

 

2020 TRD OR 4x4 with 46,000 miles and averaging 21 mpg (per the truck) I do about 50/50 freeway and city in San Diego. No complaints

 

The only legit numbers in this thread is from airforceb2cc early on in this post at 12.7 daily driving.
I pull in around 13.5 at best!
I live in SoCal and if i am not coming home from Vegas or LA (down hill, cruse control, non stop for 100 miles) i can't get anywhere near 20 MPG...
Thanks for the entertainment - "averaging 21 mpg" ...LMAO

 

sorry I guess, for answering his question? Again, “per the truck” is it legit, don’t know.

 

Maybe when I first got it, stock. Now I get 14 mpg on a good day! Haha.

 

I average 17.5-18.5 mpg. I’ve hit 20.5 mpg on highway only. All those numbers suck to me, but oh well.

 

In warmer temps on long highway drives I'll get typically around 23mpg. I have seen as high as 29mpg on flat trips. Around town in stop and go traffic it's significantly less. Winter temps make my mileage marginally worse due to gas blend, 4wd, etc.

 

36mph at 1k rpm, so 5th or 6th gear going down a mountain pass (clearly not engine braking) with a tail wind I presume? That's a sneaky anecdotal piece of data right there haha!

 

29? Downhill with a tailwind in neutral. Maybe.

 

Lucky... I only get 28...

 

Has anybody here done a before and after fuel economy test with and without a tonneau cover and/or a cab over the bed?

 

Mythbusters did that to death... here is part 2 where they tried it again. Apparently a cargo net is the best fuel option so in my opinion just do you what you like it's a truck =)

I never trust a vehicles built in fuel mileage calculation, since it has no way to accurately know how much fuel has actually been used over a certain distance. I have always manually calculated, though for the last 7 or 8 years, I have used a smartphone app to do it for me. See my .sig for Fuelly data.

Of the 76K+ miles on my Tacoma, I would estimate 35 - 40% is highway driving. What I can tell you, is that when I am just driving around my home/local town, I average 16 - 16.5 MPG per tank of fuel, per Fuelly. When my wife are taking long road trips, where I am highway driving (70+ MPH constantly for the entire tank of fuel), Fuelly tells me I get up to 19.2 MPG.

My truck is 100% stock, no wheel/gearing/suspension/other mods done, other than going up from the OEM 31" tires to 32" tires about 30K miles ago when the OEM Goodyears wore out.

 

30.9 - I'm jealous

 

My normal daily drive, 50/50 city/highway

 

My 2019 is averaging high 18's lately after I added a bottle of Royal Purple cleaner a few fill-ups ago.
40% @ about 45mpg, 40% at 70mph, the rest in low speeds.

i just need it to be close or better to 18.9 so my wife stop complaining about mpg compared to her RAV4.

 

@BigFatDynamo, save your money, fuel system cleaner won't do diddly-squat for fuel economy or your fuel system.

 

I got 11 yesterday

 

Are you saying that a clean fuel system doesn't affect gas mileage or that fuel system cleaner doesn't actually clean the fuel system?

 

Both. Modern fuels have more than enough cleaning agents to keep all fuel systems in tip top shape; you cannot clean something cleaner than spotless.
