Hi everyone, I’ve got a 2025 GX 550 and usually fill it up when there’s about 20 miles of range left. I’ve filled up gas in the car five or six times now and I’m consistently only able to load 16 to 16 1/2 gallons.

I’m curious what experience others have with the car. I understand the tank is supposed to take 21 gallons but I’m getting nowhere near that.

Thanks

 

We haven’t received ours yet (February) but there was some recent discussion about fuel quantity here;

thanks for pointing me to this thread. I think it sort of gets me validation that the tank seems to only take 16 gallons when it has about 20 miles left

 

OP you do have a 21 gallon tank. The “ 20 miles left” is leaving a huge 3+ gallon safety margin. GXs have always done this at least since the 2nd gen.
