I've never used the 909, but obviously there is some difference:

As far as the other smoke fluids I've already mentioned, I've had no damage to the smoke unit. The real difference is the output of smoke. The regular Lionel fluid that comes with the train sets produces the least amount of smoke, and that's probably intentional. Most kids getting a starter set are going to have it set up around the Christmas tree in the living room with Mom nearby. Mom doesn't want a ton of smoke smelling up the living room.
Again, I've used many other fluids and the Lionel Premium puts out the most visible amount of smoke in my 4-4-2 starter type steam locos with the old style puffer smoke units.
Unlike the videos linked above, you DO NOT want to put that many drops of fluid into a puffer type smoke unit... that'll make it not work.
