Only getting 17mpg

Towed a full 5x8 U-Haul trailer from AL to NC. Averaged over 19mpg at 70mph in tow/haul mode. I was pleased.

Granted, it wasn’t an overly heavy load (maybe 2000lbs) and there was no significant elevation change, but the LC pulled it effortlessly and I probably could have operated in normal or eco modes in order to drop the revs a bit.
 
I’m 17-18 fair amount city drive , stock 20 inch and 100 degree plus outside of Sacramento CA, I don’t think the AC has been off since I got the car , now at 1000 miles .
I’m Sac area. We’ve had ours since mid September and I’ve yet to see a single LC. I just did a search on the forum just to see if Sac gets any mentions. I think you and one other person.

Hopefully your mpg is ticking up by now.
 
I had the dealer put on BFG KO2's before I picked up my Land Cruiser FE. They are the same size as the stock (265 70 R18) but I am only getting 17mpg. I have around 2500 miles now and it has not changed. Any one else having the same issue?
Same tires, same mpg for me. 20 only on highway at 60.

I now have 7840 kms on my stock 1958 - my gas consumption steadily improved until about 4000kms & I now manage in eco mode with 91 octane & a mix of city / country/ highway to get an average 9.2L / 100km (25.57 miles per US gallon) Just did a trip today of 340km each way on rural highway trying to hold an average speed of 94km or 58.04 MPH (speed limit 80). on the way there I got 9.2L / 100km amd on the return 8.0L/100km (29.4 miles per gallon). The difference for the return trip was I filled with a different brand of gas than I normally use & the air temperature was slightly cooler @ 17C on the return vs 19C on the way there - speed was about the same

Note to self. No KO2’s for Miss Daisy.. currently getting 24+ mpg, mixed city and two lane highway driving, eco mode. (ethanol free 93 octane) with stock Michelins (33 psi) still on her. That will drop ~2-2.5 mpg when I start using E10 fuel, once I am totally moved out of Florida and up in NC, where I belong.
 
Just double checked my trip computer reported mileage on my last 31 mile trip with my BFG KO3s (265/70R18 124S) and averaged exactly 20mpg. The route was a combination of city streets (35mph), state highways (55mph & 65mph), county roads (45mph), and rural paved roads (25mph). My highway and county road speeds probably averaged 5mph higher than the posted limits. The roads/terrain on this trip were very curvy and undulating. I was in NORMAL driving mode for the entire trip.

Well I'm only getting 14.3 at 88 mph.
The whole problem seems to be an improperly installed flux capacitor.
I was promised 200 mph per gallon with the flux capacitor.
I paid 80 K for. The rest of the vehicle was on the house.

FYI. Top end speed is 108, so I heard. 👀

FE. 4,000 miles. Still in the 15-18 range no matter what ive tried.
Im taking it to dealer soon to see if they can run a diagnostic.
If not fixed im dumping this car.
I could get a defender, GX, Cayenne with v6 and have this gas mileage.

Yes I get around 19 mi to the gallon with the stock wheels on the 1958. So about 2 mile per gallon Less with ko2 tires seems about right.
 
This topic has been posted about a lot on here. Including by myself. I’ve had mine for 4 weeks and first thing I noticed how bad mileage was. I’ve driven 3k+ miles including highway to FL from TX and can’t get above 16.8. Have done everything I can think of 🤷
It's amazing Toyota can get away with those false claims about fuel efficiency when very few people ever get that actual mileage.
 
Based on the comments in this forum, this seems to be the math...
FE Style roof rack = -4 MPG
BFG All Terrain Tires = -2 MPG

Based on that math, if you can get 21 MPG on a LC LC, you add the FE roof rack that drops to 17 MPG. Add BFG KO2 AT Tires and it drops again to 15 MPG.

Anybody with a FE getting more than 17 MPG?

Yes.... 18 - 20 depending on the terrain (dirt vs Hiway)

A couple of trips in the last few days, while driving Miss Daisy (FE with roof rack), stock Michelin’s at 33 psi, 93 octane Ethanol free, two lane country highways, mostly on cruise control, unless in the twisties. So far, I am very happy with this truck. When I switch to E10 fuel, the mpg’s will drop about 2 to 2.5 mpg.

Got it. Commute around 23 miles a day in Eco mode mostly flat here in AZ. Because it is 100 and HOT out, yes I do run the a/c to keep it manageable. As far as accessories, just the stock roof rack that comes on the FE. Thanks for the break down!
I live in Coachella Valley in California. More hills but same heat. I am getting 17 mpg as well with stock tires. About 900 miles on the odometer. Will reset after break in oil change next week. Cheers

You make a solid point about ethanol in the fuel. Most northern states add 10%.

Using that information, here's the revised formula...
Advertised MPG = 23 MPG Combined
10% Ethanol fuel = -2 MPG = 21 MPG Combined
FE Style roof rack = -4 MPG = 17 MPG Combined
BFG All Terrain Tires = -2 MPG = 15 MPG Combined

Go with pure gasoline (If your state sells it) and you'll be closer to the advertised fuel economy.

@EOD Guy Does your state sell Ethanol free gasoline? That could account for you averaging 18-20 MPG.

They do but you have to hunt for it, I don't. I also run 87 on a reg basis, I fill up with 91 with traveling in the mountains of TN, KY just for the extra power.
