I would never add STP or other "treatment" to my oil,in any engine. It can messwith the additives already present in the oil. Read this from the latest Blackstone newsletter, which is a reprint of a Road Rider magazine article from 1992: http://www.blackstone-labs.com/newsletter.html

No offense, but this from a guy with three gassers? Have you actually used Lucas in a diesel? Not trying to pick a fight, just wondering if you really are speaking from experience.
Lucas is good to add in a diesel.

Fair enough. Their in-store demonstration displays make it look like it turns the oil into some form of jellied adhesive-like substance. I don't know, it just looks like the viscosity is increased to the point of becoming... well, not good.
Admittedly, I myself am not speaking from any experience with it. I've tried an array of fuel additives, but never anything in the oil.

Not sure why, but I have had a VW Bug my whole life (the same one, long story) and every mechanic that has worked on it has told me not to use that stuff in the Type 1 motors. I know people with high-mileage waterboxers though that swear by it.
