Well Clevy, it's not us at
Auto Parts Canada Online that make the claim about zddplus, it's zddplus that are claiming that.
This is what part of the article says.."It has been proven that the addition of ZDDP helps to protect the engine by developing a film on cams and flat contact points to shield from extreme pressure and heat at the contact point. This film protects the base metal of the cam and lifter from wear. During normal service, ZDDP becomes phosphorus and zinc compounds, thus the ZDDP depletes. Studies have shown that a certain level of ZDDP is required or else depending on the extent of use of the engine, at around 3000 miles of operation, give or take 1000; ZDDP levels can drop below adequate levels and cease to provide protection like it should. “According to the SAE Tech Bulletin # 770087 [1] , operation of a flat tappet engine without adequate EP additives such as ZDDP quickly leads to lifter foot scuffing and cam lobe wear. Camshafts are typically only surface hardened leaving the core ductile for strength”. The experts say that once the cam lobe wear is up to 0.0002, the degradation that follows is fast and usually disastrous."

All I am saying is that as a Classic car owner I use it in both my cars and have done for years, as an owner of a car parts store I recommend it, based on my own personal experience....I really hope I do not need to "Get your flame suit on cause the fires are lightin".
I do believe that Zddplus has some more facts on there site. But of course I can not say exactly where they get them from.
I very much appreciate your point of view, and thank you.
