The low-fuel warning appears while usable reserve remains, and fuel can remain in the tank, lines and module. Temperature, pump shutoff behavior and vehicle angle also change the amount accepted. Do not continue forcing fuel in after the nozzle repeatedly clicks off; use the gauge and range estimate as aids rather than attempting to prove nominal capacity at the pump.

2025 Chevy Suburban Fuel Tank Capacity: 28 Gallons FAQs
How big is the 2025 Chevy Suburban fuel tank?+
Approximately 28 US gal (106 L), in both 2WD and 4WD form.
Why does my Suburban never take 28 gallons at the pump?+
28 gal is a nominal tank volume, not an expected refill amount. The low-fuel warning appears while usable reserve remains, and fuel stays in the tank, lines and module. Temperature, pump shutoff behavior and how the vehicle is parked all change how much it accepts.
Does the Tahoe use the same tank?+
No. The shorter Tahoe is listed at 24 US gal. Do not substitute its figure, and do not carry the 28-gal number back to an older Suburban 1500 or 2500.
Should I keep adding fuel after the nozzle clicks off?+
No. Repeated clicking means the tank is full at that filling angle and temperature. Use the gauge and range estimate as aids rather than trying to prove nominal capacity at the pump.
