  1. Anyone using a higher viscosity oil like 20w50?

    ZR-7 Maintenance
    Curious if anyone here is using a higher viscosity oil. I have been using 10w40 fine, but being that these are air cooled engines that run at such high RPM's (and some higher miles these days) I wonder if anyone has bumped it up? I presume no issues?
