About 2.5 US gallons. I carried a gallon of gas and drove mine empty once, just to see.


edit: In detail, I filled, drove until light on, refilled and noted quantity, drove empty, added one gallon and took it into account when I filled again.

without exact-er numbers, when the light came on i have once due to necessity, gone about 60 miles without the ac draining power, going about 60 mph drafting big rigs on interstate. i now estimate 50 miles and often stop sooner when light comes on.

I have an old Galaxy Note that I use as an engine monitor running Torque. I have it set up to run a fuel gauge that reads out what the car's computer thinks is left in the tank, displayed in gallons.

The light consistently comes on when the car thinks it has 2.4 gallons of usable fuel left. There is literally zero variation in that number from what I have observed. It's always 2.4 gallons. I'm not sure if that's what's actually in the tank, but that's what the car thinks is there.

Whoever said three gallons isn't wrong either, though. 2.4 usable gallons is about three gallons of actual fuel in the tank, since there's roughly a half gallon of fuel at the bottom of the tank below the pickup that the car can't use. Tcoat can confirm that the unusable fuel at the bottom is to give water and debris a place to collect without being sucked up into the pickup.
