Land Cruiser Fuel Tank Capacity

[Marinna]

What do yall do that you need more than 300 mile range? Isn’t 300 miles all we ever got with regular 4/6/8 cylinder toyotas? Homies in 80 series on 37” tires probably getting 200 mile range and doing ok… there is gas stations every 60 miles in usa where most people live.

I find it funny that you can fish out a lot of haters if you dare to use this as an argument for EV, even if the sole purpose of the car is to drive in the city and highway.

Back to the subject, 300 miles do give me a bit of anxiety. The cruising range of my daily drive has 600 miles as a comparison. I can almost drive from NorCal to Vegas without refueling. My plan for the LC is to cruise long distances instead of commuting within the boundary of civilization, which is probably where you came from. I did one trip earlier to drive from Northern California to Jasper Alberta and come back. I’ll have to say that for some part of that route you do have to mind your remaining mileage and better never to drive with gas lower than 1/4. That means just for safe I have to refuel every 200+ miles or so.

I currently only mount one 3 gallon rotopax on the roof. For the future I am considering to carry two NATO jerry cans instead for trips like Baja or Alaska so I have another 200 miles cruising range. That would mean either RTT is out of question, or I will need to modify my rear bumper to carry these additional weights.

Ok, let's quit messing around with Jerry cans or auxiliary gas tanks. What we really need is the extra 107 gallons of the Gas Dingo ️

What speed are all of the 19.1 or less driving at? 80-90mph? I average 25. mpg, have hit 27 mpg. I also don't drive faster than 75, most times 70 mph. I can afford to get where I am going 10 to 15 minutes later. This is all highway interstate driving throughout Arkansas on I-40 and I-30, neither of which are really very flat. 2 lane highway for example Hwy 7 all up and down hills, I can get around 23 mpg. I am constantly attempting to get my rpms below 2K. The 4-runner trail I drove for 15 or so years, never got over 22 and to get that I had to baby it.

I have noticed that the 2025 LC I have also behaves the same way with cruise control that my 4-runner did, in that the truck will upshift very quickly, thus increasing the rpms when there is a slight uphill. If driving without cruise I can easily take the same grade in the gear I am in.

I am running stock tires, 20" Dunlops, but will switch next year to something from Toyo most likely the R/t, but will stay with 20" rims.

For me the mileage is excellent and better than I had hoped.

I agree that the testing from EPA is supposedly done at 55 mph, which in the U.S. is way to dangerous to drive on the interstate as some idiot going 85 will hit you as they are texting and not paying attention.

Keeping the rpms under 2K is where I am always attempting to me on the highway, over 2K and things fall off very fast.

I don't think I have ever owned a vehicle that got the quoted EPA mpg lol, I don't even pay attention to it. I think the best I have gotten in my LC is 21mpg (on the screen, not using a calculator.) I do get better mpg around town than my F150, so it has that going for it. The LC also drives like a go-cart compared to my F150, so there is some me involved, the little 4cyl turbo hybrid is a fun little engine.

As far as the range/tank capacity (I think I have posted this before), it bothers me because I live in a hurricane prone area and there have been fuel interruptions on occasions for other reasons, I have a habit of filling up at half a tank, many times even at 3/4. That is often in the LC. It doesn't bother me, but I wish it was otherwise.

My F150 has a 36gal tank and gets 21-22mpg (EPA says 24) on the interstate. I have actually driven to S.FL (640mi) w/o stopping for fuel. That is nice. lol.

People complaining about their MPG is senseless and there are too many variables; location, weather, weight, driving style, etc. I got 9mpg the other day

Are you running the A/C, it’s killing my mpg

 

[Markarian421]

I just drove from CA to CO and back, two mountain ranges, most of that (other than the twisty mountain bits) was around 80 mph. Duratrac RT SL offroad tires, cruise control, normal mode, AC & cold box running the whole time. I mostly got around 21 mpg. I'm starting to wonder what I would have to do to get much lower than that in normal driving, for any longer trip I always end up in the 21-23 mpg range.

 

[NoMe cruiser]

ECO mode, 87 octane exclusively, mostly 50-60 mph on hilly rural roads.
I know it’s easy for people to cheat the mpg that’s why my pic shows range. Honestly, I haven’t been in the woods since May, and when hunting season starts my mpg will go down to 18 and my range to ~300.

This is how I looked into these numbers.

Cruising range decides the distance between gas station stops, and gas mileage decides how much fuel I need to carry once I need to drive longer than my cruising range.

In normal conditions, I carry 3 gallons for “mental peace” that I know I could have an additional 60 miles runway. So in between big gap I can keep pushing to the next without early stop. In this case gas mileage is not as important to me as my tank size. I found this apply wells when I have to drive through a big mountain range when the first half is a steep up climb and second half is mostly just coasting.

In overlanding conditions, it did take additional planning. If I want to drive through 300 miles unknown terrain safely, I’d add 50% range in my fuel requirement, so I assume I need to have sufficient gas to run 450 miles. In that case the additional 150 miles I will need to prepare more than one NATO Jerry can to cover it. Now the gas mileage becomes just equally important to me as tank size. Because I do not like to carry all these big Jerry cans and Prada doesn’t offer me too much mounting opportunities for these big and ugly guys.

I've never come close to 300 miles with a full tank. Not even remotely close. This is not a result of aggressive driving either, I am quite gentle, I coast a lot, & can maintain EV power only for a while before it bumps the ICE on.

I live in SLC so we do have decent elevation changes depending on where you go. However, I can keep it on relatively flat paved surfaces & still never break 280 total mi.

Wow! 13.4mpg? That’s about what I get when I wheel off road through a foot of snow. Did you do any modifications to your vehicle? City miles?

The display only counts something like total-2 gallons. Mine tends to display around 315-330 when I fill it up recently. And when I drive it to 0 mile range and fill it, it's less than 16 gallons.

 

[ct1958]

I just wrapped a trip to Montreal Canada from Connecticut. It’s about 5.5 hours each way. Bone stock 1958, I averaged 24.6 on the way there and 23.7 on the way home. Brutal storms and wind on the way home. I drove 70 to 75 on the there and about 40 – 65 on the way home as visibility was about three car lengths at times.

I just refueled so it had limited MPG data from the trip, my total average is around 17mpg, still incredibly low.

The only mods I have are a set of LT275/70R18 A/Ts & a smowl 2" lift, but nothing that would drop the average that low. I know people say lifts negatively impact mpg, but if they do its incredibly marginal. Same with these tires, I am only looking at maybe a 1 mpg lose on pavers, max.

Okay thanks for the clarification on the MPG. Keep in mind these are 4 cylinders. With the lift and tires you’re probably losing 5-6 mpg whereas a 6 cylinder with those mods might lose 2-3 mpg.

Are CAFE standards nullified?

Interesting nuance many missed regarding the big beautiful bill that recently passed in the US. Apparently, it zeroed out all penalties for missing the CAFE requirements. Some industry analysts are now predicting some relief on the pressure to downsize engines.

An interesting question, what would SUV manufacturers build if not constrained by fuel and emission requirements?

One of the most important provisions in the One Big Beautiful Bill has gone completely unnoticed.

Do you have BFG KO2s or KO3s or Falken Wildpeak AT4s by chance? There are some tires that are the dimension you listed that weigh as much or more than tires even 285 width or larger than 34”. If your unsprung weight at each corner went up by 25 lbs+ and you have a 2” lift, the combo would def shave off more than 1 MPG.

 

[doubleD]

Does anyone know if there is room for a larger (GX 550) or aux tank system?

Biggest issue so far with new LC is range anxiety which is disappointing for a non-EV.

If MPG was 21+, I would be less concerned.

[See Updates at end of this post, last edit 11/29] All, this is bound to be fairly long. I'll try to keep it as tight as possible. First, a lot of haters promised me this tank wasn't going to fit because china. Well, I have a 500-mile range LC250, and they don't. 😂 I initially posted some...

[Shorty]

We can’t compare as we have the 2.8 diesel tractor (reliable engine) but converting back I’m getting approx 26 miles per gallon. I get about 680 miles to the tank (29 gallons) hope my math is good converting everything.
