You can find that oil everywhere where there are boats (outboards)! Also on Amazon.
This is the one I've bought from Amazon : https://mannol.de/en/?action=accessory_ ... d%20Marine
Simply type TCW3 or TC-W3 in the search box.
This is the one I've bought:

There are some additives that do have positive results Yves has done some impressive research on a two Cycle Oil additive that is interesting. It's worth a try. I am impressed that yves came up with similar properties on the Lucas Additive that achieved positive results in the two vehicles I tried it in. I will stay withe Lucas additive and run my Jeeps and CCKW exclusively on Non Ethanol Fueu which should keep the fuel systems healthy in my MB, M-38A1, and CCKW.

Hey guys, thus really piqued my interest. Tell me more about your findings and the benefits of this practice with 2 cycle oil in the fuel. I have had 2 cycle dirt bikes and a couple of street bikes that had 2 cycle engines, but pre-mix was mandatory in them. Where my old trucks are concerned, I have always used Marvel Mystery Oil in my fuel.

I guess it's normal.
If you look at the Lucas Upper Cylinder additive safety data sheet, you will see that the main component is CAS 64742-54-7 € @ 60-100 %
CAS 64742-54-7 is an Hydro treated Heavy Paraffinic Distillate.
They even don't mention any other ingredient!!
If you make a search on that CAS 64742-54-7, you will find that it is also the main "ingredient" of a ... two stroke oil made in Texas by ICP INTERNATIONAL, LLC :D .
So the Lucas additive could be pure 2 stroke oil :)! The loop has looped.

The LUCAS Upper Cylinder additive and Marvel Mystery Oil have not very good results in the above HFRR test because they were added to diesel fuel which has better initial lubrication properties than gasoline.
To be correct, the same test should be done with pure gasoline and ethanol gasoline.
However Lucas claims that their additive is for gas and diesel which looks not totally true in terms of effectiveness.

PS
Paraffinic distillate:
Paraffinic oils are prepared by solvent separation techniques from parafinic crude oil, which give good yield of high viscosity index stocks containing a lot of wax.
Paraffinics have good thermal and oxidative stability and good high-temperature viscosity characteristics.
Low temperature dewaxing of paraffinic base oils is also required to achieve the low temperature flow requirements of ATF.
