Prior to Arma 3 v1.94 If the vehicle is not alive, it always returns Nothing, which you should check for using isNil.
If the vehicle is unable to carry that type of cargo, it returns -1.#IND, which you should check for using finite or < 0.

Since Arma 3 v1.96 the return value for vehicles that are not configured to have ability to refuel other vehicles is -1. (Prior to that the value was negative infinity)

If you have ACE mod installed, note that it removes fuel cargo from vehicles so it could appear that the command always returns 0
