Its working as it should. I never get more than that amount of time before more smoke fluid needs to be added. That goes for my lionchief plus trains and MTH. As far as what you can do different I cannot help with. Maybe one of the more seasoned folks here can chime in and give you some ideas on mods you can do that will supply less power to the smoke unit so the fluid will last longer. Of course that will result in less smoke output.
