2008 WK fuel tank size and light

Can can anyone tell me the size of the fuel tank on a WK? 5.7L/Auto if there are different ones. Also, at what point is the low fuel light triggered?

Re: 2008 WK fuel tank size and light

All the same fuel tank.

I believe 21.1 gallons is the listed capacity. No hard and fast rule as to when the light comes on (from what I have seen). I think it is related to the distance to empty calculated, and not the total fuel in the tank. Most people say between 2 and 4 gallons remaining.

Not positive about any of the above, as I value my fuel pump and never let the tank get below 1/4 (and usually keep it above 1/2).

As far as the light it will depend. My light comes on when I still have 5 gallons of fuel left but that is due to the size of my tires being larger than stock. On average though it should be about a gallon or 2 left when it comes on. Enough to get to a gas station and fill back up.

Yeah sometimes mine has come on as early as 35 miles left, and as low as 15 miles left on distance calculations.
