I found this article, on adding lucas to oils, and the results are interesting.

I read the link and it was interesting but I'm not sure it's accurate/truthful, there are lots of folks that swear by Lucas additives. Interesting link though, gives folks something to think about.

I was told by a reputable Raptor engine builder that the ONLY stock rod he's seen that didn't look like it was used came from a nitrous quad running Yamalube and Lucas additive. He said it looked brand new, no wear or heat marks at all. We know the Raptor it came from, it was run hard with lots of nitrous.
