Has anyone experienced carbon buildup in their RX8? I had warranty work to clean it recently performed on my '04 and was wondering how I can keep the carbon from building up again. They said I need to keep it revved up at 6000 rpms, which is easy enough to do when shifting, but I drive in mostly highway traffic.
