Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

As mentioned, the wet steam in these pretty much "lubricates" internal areas on its own, so all i use is a few drops of Wilesco oil before startup.
(On toy engines that is, other models get 320/460 steam oil.)
I find it much more important to keep bearings and connections oiled, with a good automotive lubricant like synthetic Mobil1, as it is in those parts i´ve found the biggest wear during the years.

I appreciate this post, I watch a lot of YouTube videos of people running "toy" steam engines and many/most hit the steam chest first with oil....then I see them move on with the SAME oil dispenser to the oil cups and Rod bearings and other moving parts....from what I understand, Steam oil has tackifyers and other additives to keep it from washing away in the wet and heat....makes sense those ingredients may not flow the Best thru tiny oil cups or wick into nice tight fit rod bearings at room temperature...
   So what I am picking up on is Wilesco steam oil may be the thinnest steam oil yet well suited to wet running "toy" size engines...than as the size of the engine gets larger...or if the steam is dry or super heated we may want to keep moving up to thicker grades for better protection....?
