I only get 3.5 damn gallons on a fill, when down to 1 bar, before the nozzle shuts off. (Once I had 2 bars/1/4 tank left and the gas shut off at TWO GALLONS.) I have twice accidentally overfilled the tank (and both times, at less than 6.5 gallons out of the pump), not because I'm trying to squeeze 12 gallons into my 8.7 gallon tank, but rather because I'd like to drive for more than 2 hours at a time without running out of gas.Overfilling your tank is not due to a defect. The fuel nozzle will shut off multiple times before that occurs, and only somebody who insists on being stubborn and taking risks will continually fight through each fuel nozzle shutoff above and beyond the 8.7 gallon tank size that has been repeated over and over in this thread, in the owner's manual, on smart usa's website, etc,.
If by some chance this has ruined my car, I fully expect Smart to cover it, since it is only because of their defective tank that I had to slow-fill my car to get even close to the stated gas tank limits.
