I have been using 5w30 Amsoil XL (7,500 mile oil) since the first oil change (3,500 miles). I could tell a slight increase in valvetrain clicking at first, but two oil changes later the noise is subdued. I have been impressed w/ the oil. Low consumption (1/2 quart added over 7,000 miles) and the oil always looked clean (golden brown). Oil temps range from 207 to 220 in 95+ heat (spurts of hard acceleration-220). I would not worry about the valvetrain. This is a very good oil.
