Oh no, not another oil thread, please no. That is where I used to spend my life when I rode Harleys. Conventional v. synthetic blends, full synthetic, Red Line, Amsoil... I don't want to get into that. On my Harleys I would switch to full synthetic on the very service (those big air cooled V-Twins run so hot) as suggested by the Harley dealer every time. However, on my CB, I'm gonna stick with Honda's 10W30. CIP57 suggested I put in Honda' synthetic 10W30, but my Honda dealer says to wait until 8K. So the real question is more like synthetic now at 700 miles or later at 8k or even 4k for that matter?
