Maintenence of the HO Slope Tender with smoke Pennsylvania

[tctrains23]

Does the locomotive have to have the "smoke oil" at all times when running?  I've been told that it does.  My previous locomotive stopped smoking and eventually stopped working.  Any thoughts?  I want to make sure I'm operating it right.  There were no instructions with the locomotive I just bought.  Thanks!

It does not need to have the smoke fluid in it at all times just don't run it for a really long time or there is a chance of melting/deformation.
