Man I don't know about adding crap to the motor to improve the laws of nature, "friction". The manual says to not add any addatives and under warrenty, I would not mess with it. My Saab's been running smooth at 50,000 miles now and I've drivin it hard allot. Allways changed the oil with Mobil 1 full synthetic per the manual and at 3-5K intervals and as a daily driver, it never, ever, ever burns any oil. I guess we would have to see some solid tests or long-term issues with such stuff. Might be a waste of cash too??
