Some people used 3in1 type lubricating oil!
Also not a good idea...
In 1964, the Seuthe type smoke units used in Tri-ang Railways locomotives from 1961 were mainly replaced by the introducton of Synchrosmoke units.
These were also known earlier on as Synkro-smoke, and other variations in spelling, etc.
The exceptions were the locomotives where the Synchrosmoke units could not be fitted, such as the S.R. L1 4-4-0, and the G.W.R. Lord of The Isles 4-2-2.
The Synchrosmoke units use a cast metal box, with a piston in a cylinder to push air into the box driven by a gear wheel, which is driven by the motor worm.
The box contains a wadding material, and on top of this is a heating element, that looks a little like a fuse, with a metal conducting cap on each end.
The element is wired in parallel to the loco motor, so the amount of voltage, and therefore heat was governed by the speed control setting.The air forced into the box by the piston expels the smoke in "puffs" that are synchronised to the driving wheel speed by the gear drive.Complicated to describe, but it works!
Some Examples of Synchrosmoke fitted locomotives.

Battle of Britain Class 4-6-2 Tender Locos (1969-1972)etc. It is important to only use proper model railway "Smoke Oil" in the smoke units, to avoid problems, including possible element damage.The smoke oil marketed by Tri-ang and Hornby has come in a variety of plastic tubes and sachets over the years. The last Hornby issue I have seen was a small plastic "pot" with a screw lid (R.8111).
Until the Hornby "Pot", the various containers of Smoke Oil had the part number R.521, including the sachets sold by Hornby to go with the later Smoke fitted locos that use a plastic smoke unit, including the 4-4-0s (SR Schools, Midland Compound, GWR County, and LNER Shire, and the GWR 2800 and LMS 8f 2-8-0 locos.
