use a full synthetic oil or not ???

[Shifu]

I understood the word synthetic, in this context, meant man made.. ie made up of oils other than Dino oil...(and filtered through micromesh made from unobtanium).

You are right Steve. In English the word "synthetic" means also artificial or "man made" as oppose to sometihing made by mother nature. We were discussing the word "synthesis" however, which means "to combine". Most of the man made materials are made by combining atoms or molecules into new compounds hence the result of this process is a synthetic material which means a result of "synthesis" or combining different things.
Andto refine them they use hardtogetium as it is a cheaper alternative
