Well if you have seen my videos on smoke fluid, then you would realize that 15-20 drops in a dry smoke unit, is not going to achieve max smoke results. If your smoke unit is FULL of fluid, you will notice a difference in smoke output. Even Lionel Premium puts out more smoke than JT's, but it smells so fowl.
Sure you'll get some smoke from any of the different brands of fluid, but with only 15-20 drops in an engine that has been sitting for any length of time, you'll get some burnt batting more than anything.
Once you burn the batting, your smoke unit performance is greatly affected. Not enough fluid is the biggest cause of burnt batting. Many people run there engines around not even realizing their smoke unit is on, and dry.
