and it comes with quick results and doesn't cost me $.
Tx for sharing that Zeng... since you've done this test, can you tell me the light source you're using?

It uses a special kind of chromatography paper, I think.
I got overwhelmed fast too upon doing an initial Google search (hence why I made this post looking for guidance). I was thinking of emailing the author of the article and asking him what he recommends.
Perhaps Zang can provide some insight on this.??? I'm really keen on trying this test out. I understand it's resolution won't be as good as some lab performed test but I'm ok with that. I'm looking for a relatively cheap, quick and dirty way to check certain oil parameters like soot, fuel and coolant (presence of).
