Marx Smoke Fluid

I recently bought a Marx train set from the sixties. It has a diecast metal 2-4-2 steam engine # 666, a tender, a boxcar, a gondola, an autorack car and a caboose. All the cars have what I call “scissor hands” couplers.The engine has smoke. The box says it is liquid smoke. There are no instructions with the set still. Can anyone tell me if lionel smoke fluid will work with this engine? Thanks

Yes it will work.

Anyone’s smoke fluid will work. I prefer J-T’s Mega-Steam Coffee “flavor” myself.

Some folks report that the Lionel smoke fluid gums up in the Marx smoke unit. I use Mega-Steam with good results.

I use Marx scented Mega-Steam.

been using Lionel,MTH,Mega Steam in my 333 & 666, both smoke great.

Thanks to all for the replies. I really like this set. It is in very good shape and runs well too.
