What kinda gas mileage are you getting?

21.47 on my last tank of fuel.

 

Like greengs said a few posts back, when I commute to work (35 miles on LA freeways) I’ve been seeing 25+ Mpg often. Otherwise it’s 17-21ish.

2018 TRD Sport 4x2.

 

2 tanks now driving around Portland OR

 

Exactly. Everyone keeps telling me to get a Prius.

 

Haha jk. City 19-21, highway 24-28

 

17.5MPG at the best.
14.8MPG at the worst.

 

So bad

 

I average 18-19 going 70-75. Mainly highway commutes to and from work. Dbl can long bed off road with 265/70r17 a/t

 

Just filled up. 294.7 miles on 11.071 gal. For 26.6mpg. Broke the 25 mpg barrier on 3 of last 4 fill ups. Was always 23 or 24 mpg till I switched to Pennzoil Platinum 10w30.
Have used 0w20 EP, PP 0w20, TGMO 0w20, and something from the dealer that resembled 15w40 when I drained it.
2016 4cyl. 4wd 5 speed.
LCE header.
Amsoil 75w90 in front diff and transfer case.
Redline MT90 transmission.
Super Tech 80w90 in rear diff.
245/75R16 Michelin LTX Defenders at 35 psi.
By the way, I tried PP 5w30 and mileage was worse by about 1.5 mpg so I drained it after 2000 miles.
Unless my mileage tanks this winter, PP10w30 will be my year round oil. Nice and quiet. 4.7% NOACK. It’s weird that 10w30 gives the best mpg.

 

Great report!! I’m guessing the main factor is 4cyl?

 

I have had mine a week and it is around 17 in the city/some highway.

My 2017 ZL1 gets 25 mpg on the highway and I had to pay a gas guzzler tax.

Go figure.

 

I have a completely stock DCLB OR and pretty much only cruise 55-60 on backroads and get 21.5 on average. I’ve never seen 23 or 24 mpg, or more, as some report.

 

Trd sport 2wd. Usually get between 14.5-16.5 mpg. Running two roof racks and a rear camper. Also on 285/70/17 with wider/heavier rims. I do a mix of city and highway driving. I know I sometimes have a heavy foot especially with the new transmission update and accellerating but it sure is fun to do.

 

I get 12-15 and it's just my roof rack. I'm going to try a different fairing to see if I can make it better.

 

2018 4X4 Off Road about 6500 miles on the truck. The Averageis 19.6 MPG since new.

 

So did I! It's such BS.

 

You can see my mileage history in my .sig below.

2017 Off Road, 6 speed manual trans, stock suspension/tires/wheels/everything. Daily work commute is ~30 miles, elevation change about 1,000 ft difference between work and home, I usually drive about 70 - 73 MPH. Bought truck new in April 2017, as of today I am just about to hit 23,000 miles. Have never towed or hauled much weight.

 

From top of Trail Ridge Road to the Beaver Meadows entrance gate at Rocky Mountain National Park. In S3 or S2 the whole way down. Had to pull over twice temporarily. Probably could have broke 80 if I was really trying.

In more normal circumstances, I generally get 15 to 22 for each trip in town depending on number of stops, and length of trip. If traffic is really bad, or trip is less than a mile, trip mileage can be as low as 9 mpg.

For interstate driving (70-80 mph), average of 18-19 mpg is normal for rolling hills, light wind and AC turned on. Turning off AC results in an approx. 3 mpg gain (AC must effect how often the engine goes into Atkinson mode), which gets me close to the rated highway mileage. A 15 mph headwind verus tailwind results in an approx. 5 mpg difference in mileage.

As others mentioned, driving around 55 mph on flat ground will result in usually beating the rated mileage but nobody drives 55 if they can help it, and flat ground rarely exists in my parts.

I do think the recent ECU update has resulted in about a 1 mpg increase on the interstate. The transmission holds gears longer going uphill now, resulting in less downshifting on gradual inclines.

 

13.5
