Hey I am not a train collector or anything (although I do love trains). I bought a Christmas tarin last year that blows smoke ( or is supposed to). Well, it won't blow smoke and the directions say to add household oil (what the heck is that? Crisco?) to a little hole in the smokestack. Today I went to a hobby store and the man gave me some "smoke fluid" which he said would work. It doesn't! Can anyone help me??? This is not an expensive train (about $75) but it's very cool! help!!! Thanks Janell
