My GV holds 9.54 quarts (9.0L) I filled with two bars on the gauge. It took 6 quarts (5.68L) to fill. With two bars I had 3.54 quarts (3.27L) left in the tank. The GV still uses a carburetor and mechanical fuel pump.
I try not to run to low because the electric fuel pump for FI engines use the gasoline for cooling of the pump. The 250 Xciting's are FI.
