What type of oil do you run in your ztr? Synthetic, Dino and what weight? My dealer is telling me to run an oil with a high level zinc. I know a lot of today's oils do not have zinc cuz are automobiles have gone to roller cams and they do not require the zinc that our old engines required . However our v twins are hydraulic and solid lifter engines and IMO would require a zinc type oil. Just curious what you guys run.
