3rz gas mileage

Hey yall hope your having a good day! and just wanted to get a opinion on some people here on the 2.7l 4cyl 3rz.

Currently im getting around 14-15 mpg while on 285/75/16 on stock gearing which is 4:10s for my taco. i have the A30f 4 speed auto trans with manual locking hubs. I always hear that most people on their 4 cyls hittings 20's mpg but i cant tell if a lot of them are being dramatic and lying their ass off. Of course im 4x4 so it would be lower than a 2 wheel drive. I plan on adding armor, and already run sliders as is. Doesnt throw any codes besides a p0441.

 

20 is achievable with a 3rz for sure.

But those 285s are murdering your milage; the AT doesn't help either. You might get some back by regearing.

 

see tho before my 285s i had 31s and was still getting 16mpg??? i have never seen 18-20 in my life in this truck even my dad who passed it down to me said hes never seen that. on average i get 215 to a tank?

 

Might be the AT then, i dunno. Before I fixed the burnt valve I was averaging 15.45 towing, 20.06 mixed and 21ish on the hwy. Its been a garage queen since then because reasons, so i don't have new numbers. Mine is MT tho, but still 4wd.

 

personally the motor does idle slightly rough? idles between 640-650 recently seeing it get to 615 in drive. finally going to take of the throttle body and clean the bitch out. i also do burn oil which idk if that causes mpg loss

 

Bump

 

That sounds about right for the 2.7 with AT and 33" tires. My 2013 has 305/65/17 tires with the A4 and 4.10 gears and I get around 16-18 mpg in the summer and 14-15 in the winter (cooler weather and winter gas mix). The extra weight of the armor will knock down your mpg even more though. Here's a list of my last 2 years of gas fillups and the mpg. I don't do a lot of driving and most of it is around town. This year I did a lot less because of covid and barely did 1 fillup a month. I did add a cold air intake in Apr and it increased my mpg by .5 mpg compared to last year so far. I do tow a boat in the summer months so that probably knocks my numbers down a little bit as well.

I get 20mpg highway going 70mph with 32" C rated k02's. Around 16.5-17 around town.

 

recent trip yesterday from va to ny on a mission staright up I-95 NJ turnpike
round trip 725 + miles only 2 gas stops

legal speeds Empty1st leg nonstop................criuse set in 5th gear
1st fuel stop 19 gallons 480 miles 25.26 MPG !!

return not calculated yet
home after pullin trailer back at high speeds..............run lots harder than 1st leg
gauge needle does look bad tho..............some 6th gear running NOT legal

really no need for 6th unless running 80 mph or more
no confession here yet 6th gear was used quite a bit

home 1 day still havent fill up yet

 

+1

With my 5 speed manual 3rz and 265/70-16 P series tires I'd easily get over 20 if I kept it at 70-75 mph.

 

My 5-speed gets 20-24 on 30s. 20 is usually when I feel like messing around and shifting 5k and 24 happens with just normal right lane daily driving

 

Sig truck with 265/70/16 AT tires. 17-19, all city. Winter warm-ups on cold AF days push me down to 17. High altitude doesn't help, and also 90% of my body weight is in my right foot.

 

I just did a ~200 mile round trip and somehow averaged 26.05. Definitely wasn't being easy on it, 70-75 almost the whole way. I'm a little baffled how it's higher than advertised even. I watched my ultraguage creep up from my normal 20-22 the whole trip

On 3rd gen Tacoma sport 17" wheels currently 265/70/17 (30.6 or w/e)

Regular cab with nothing but me and some tools behind the seat. 75 degrees or so.
