Don't know my dealer well yet, but they suggested that despite what the owner's manual says, that I change my oil every 3k to start. They're going to watch my driving habits and may change that to time vs. miles......I'll go with it, BUT....I really don't believe it's necessary given that it's synth oil. Last summer I bought a restored Triumph TR6 that had 10k on a rebuilt engine using Amsoil....that 10k synth oil was as clear and clean as if it had just come out of the bottle....
