Fuel Tank Capacity and Gauge not in sync

[SKLC]

I would NOT do that. You will damage the fuel evap system, which can be costly repair bill. The Car Care Nut mentioned this in one of his videos.

Thanks, good insights…was not aware of that.

I agree with you Sluebeck - joined this forum for the sole purpose of researching this. I think this is an Achilles heal, the range is not what i had hoped it would be. Am going to figure out the jerry can mounts now (and would anyway, but this just exacerbates the range issue).

The problem I have know, is that when I put in 14 gallons it only has 224 miles of travel. Any ideas?

My theory is that the 224 miles is a projected estimate based on the mpg you have previously had. I started off with 300+ miles left on a full tank. December and January I spent a lot of time in the woods in somewhat deep snow. Locking differentials occasionally, using mts and crawl. I was getting terrible mileage, like 10-11 mpg in the woods. I started getting 230 miles left on a full tank. Since February the snow is just too deep to get out and most of my travel is to and from work. I’m now getting 280 miles left on a full tank. Averaging 18.4 mpg. I imagine someone who lives in the city and has their big toe in the turbo will struggle to get 250 miles to a full tank. This is also the reason I believe people think they only have a couple gallons left when they actually have 5 or so. Again just my theory.

You are probably correct. Fishing season has started and pulling my boat about 150 miles round trip. Averaging 12 miles to a gallon. I suspected that was the issue. Thank you

I have a 2025 Landcruiser. Got it in late November, just under 2,000 miles. I've looked through the forum and haven't seen this exact issue discussed.

According to the owners manual and specs online, the Landcruiser has a 17.9 gallon fuel tank. However, when I run my car down to essentially empty and refuel it only take 15 gallons, which tells me there is still over 2 gallons of gas left in the vehicle or the fuel capacity of the tank isn't really 17.9 gallons. Are any of you noticing this, is this normal?

I asked a technician. There is a 2 gallon reserve that isn’t taken into consideration when the range is calculated. I’ve paid attention the last two times I’ve filled up and based on my calculations it’s correct. I always add 30 miles to what the range gauge says. It’s designed that way so that you won’t drive the vehicle to 100% empty. It’s more for keeping the fuel pump cool versus anything else.

No theory behind it, that is exactly how it works.

My F150 (36gal tank, something I miss in my LC).... Drive around town for 2wks and the range will be roughly 550mi at fill up. Drive the Interstate all day, stop to fill up, will read close to or over 700mi. I get better mpg on the Interstate in my F150 fwiw.
