I suppose you could get a K+N, clean it good and then see if maybe they sell some different color oils? Maybe? As far as I know it only comes in the purpleish/reddish color.

Joelster, and everyone else, thank you very much for the serious replies, I appreciate it a lot.

I just wish everyone could let UBRF stay where it is.
