I have been doing manual fuel consumption calculations just for fun. I have found the calculation by the ECU is fairly close but a few times it was way off. Two tanks, LC was at slightly over 20 but calculated was nearly 22.5. and on the low end the LC calculated was 18.5 and I was at 15.3. I have never calculated an MPG that high since going to 285-70-17 KO3s on my method wheels. The lower end was a number of miles off road and center locked as well a 4 wheel low. My calculations still pretty much have me in the 19 MPG range. Still absolutely no complaints, my Tundra did 11 to 11.5 every where. Still thinking we are getting Prius like MPG in the Land Cruiser in comparison to the Tundra….LOL!!
How to get better MPG
- Thread starter overtrail887
- Start date
Nearing 2k miles and been at 16.3 for a good while. We had a rav4 hybrid years ago that got an astounding 35+ something mpg. For us, we’ve accepted the fact that A: we won’t come close to what we got when we had the rav4, B: shelling out the bucks for premium fuel, C- more frequent fill ups (our range has been about 260 miles)
Where we’re at is about 2400 feet. Most of our driving is highway and some county roads which ranges in speed from 50-70 mph.
It’s cool seeing the different methods and wide diversity of MPGs based on various factors. The gas credit card we use on fill ups adds points to our cruise
account so that helps limit the sting a little haha.

Hang in there. It was about 3500 miles & after a few road trips that our ‘26 LC mpg started to improve. Wife now gets 18-21 w/ 50/50 stop-n-go & highway speeds each day.Nearing 2k miles and been at 16.3 for a good while. We had a rav4 hybrid years ago that got an astounding 35+ something mpg.

I'm interested in how everyone handles manual fuel calculations. What I'm guessing is that fuel is introduced at some rate determined by how the pump handle is structured (i.e.- first lock notch or 2nd lock notch) until the pump kicks off. This level becomes "full". Then, vehicle reported miles are divided by the volume of gasoline? I really hope somebody has a different take...
Btw- I strongly suspect that the tank level where the pump shuts off is significantly impacted by the specific pump being used to fill the tank

When the pump shuts off, the first time, STOP fueling the tank… per the owners manual, and TCCN. Otherwise you risk damaging the charcoal cannister, which is a PITA (and expensive) to replace.
You have 18 or 20” wheels?Nearing 2k miles and been at 16.3 for a good while. We had a rav4 hybrid years ago that got an astounding 35+ something mpg.

What tires?
Roof rack?
Normal or eco mode?
Gotta pay attention to the turbo and battery gauges
But yes with time these #s will improve
Here are my numbers from last weekend. Can’t complain, I was jamming back home on highway 101 north from Pismo to Bay Area. Average speed was 80-85mph with hills and passing. On the way there I averaged 21mpg @ 70-75 mph
5 adults (brother in-law 220-240lbs)
An electric wheelchair
3 suitcases
2 Shihtzu
1.75”/1.1” lift
18” Bradley V @ 28lbs each
Michelin XTL (oem tires)
91 octane (of course)
Normal mode

Dealer installed wheel package ?
KMC are usually on the heavy side
Correct.

I get the gallons filled and record miles between fill ups not super scientific and it’s just for my own interests. The fueling method is I manually operate the pump at a slower/low fill speed than the latch settings to allow the pump to shut off and disengage the pump. Once it clicks to shut off the pump I am done. Others can claim and they could be correct that it might not be the most accurate for filling on a consistent basis but this is the way I do it.
The reason for this method is my 2008 Tundra had a charcoal canister replacement done and was lucky to have it completely covered under warranty or it would have been expensive, at the time it was just under $2000 to pay out of pocket. The dealer asked how I filled the tank and asked if I used the same station/brand and fuel when in town (most fill ups). I told them that I did and that it was on the highest setting for lever engagement to auto fill and pump shut off and would then do one click after that. I was informed that they will cover the cost and that using the one click method after pump shut off could be an issue, depending on the pump sensitivity and speed. They also appreciated my honesty in how I filled the tank. I was given instruction to use the lever manually and go slower with my fill ups and not click any extra times as there can be pump variations and you want to be sure to not have fuel contamination in the charcoal canister. Points well taken, grateful I did not have to pay out of pocket and I have filled this way for many years now…..just became a habit. Honestly felt a little stupid at the dealer being a car guy for many years and honestly it never entered my mind that the evap system was sensitive to over filling. Old dogs being taught new tricks.
Just FYI - this should be happening even with the latch engaged. If you encounter a pump that doesn’t still automatically shutoff with the latch engaged you should notify the attendant because that’s a serious safety concern and indicate the pump is malfunctioning.
I just completed an 1800 mile trip from CO to IA and back. I didn't calculate anything, just went off the mpg reader. Started at 19.5, alomst strictly in town, and it slowly ticked down to 19.2 when I returned. Nothing scientific, but kind of disappointed I do better in town than highway.
That's the hybrid part disappointing you haha. When we had our Rav4 hybrid, we wanted to get better MPG but with where we live, we don't really have stop and go traffic and do mostly highway/interstate driving.
Hybrids thrive in lower speed / city type situations. Not so much so with the LC since the Hybrid element is more of a torque and power booster. I've been spending a lot of time behind the pump in the last month or so
I think the operative part of any fill technique is consistency, thus the same station/pump/time of day guidance. I use the first locking position (meaning lesser flow) and wait for it to shut down. Should go without saying but nozzle fully inserted.
I just gathered fuel consumption data over an eighteen hundred mile trip running on 265/60-R20s, complete with parallel GPS measurements (limited use, I think the dithering in my GPS might overstate distances? 100% of the time GPS distances were long, seemingly by about 1.5%) using the above filling approach . I will be taking another set of measurements next month over approximately 2.5x the distance on larger 295/70-R18s. I can share the data from either/both trips if any are interested.
Seems like data needs an external measurement system to check accuracy that I had assumed the GPS was providing....
actually, maybe the GPS is correct and the LC underreports? Like on speed? It certainly follows ...
something like G-Maps or the like to validate one (please!) of the systems being used to create data for the table below
| Where | Time | What | Odometer | Elapsed | Price | Octane | Gallons | Cost | MPG |
Always drive downhill.

New personal best coming home from Big Bear, 35.3 MPG over 68 miles.
Averaging about 72 on the hwy.

Sorry you had to be towed home, what happened?
Big Bear CA is high in the mountains. It would be markedly downhill to any destination.

If you think this is good. Let’s see how many miles I can average starting at vail pass Colorado
