Default Re: Red Line versus Valvoline versus Mobil One?

Thanks for the reply Al. I am so paranoid about motor oil; always thinking I am going to wipe out a camshaft. I had a long conversation with a tech at Conoco-Phillips and it was like pulling teeth trying to get zinc/phosphorus content information about their products from him. I never did get a straight answer. In your opinion, is the ZDDP oil additive a quality product? The reason I ask is if you buy a 10 pack, it is $7.99 a 4 oz. bottle.
