"there were no other technologies" Not true. As I posted early on that board, here is a patent from Exxon: " Long life lubricating oil composition with very low phosphorus content". <A HREF="http://www.freepatentsonline.com/20050026792.html" target="_blank">http://www.freepatentsonline.com/20050026792.html</A> Here is one more from NewMarket Corp. (NEU): " Low sulfur, low ash, and low phosphorus lubricant additive package ..." <A HREF="http://www.freepatentsonline.com/20050026791.html" target="_blank">http://www.freepatentsonline.com/20050026791.html</A> I am repeating my question: who do you think will win if there is a "war", XOM or PLRO??
