Question this is part synthetic oil ( Casrtol GTX10W-40W) is it OK to use in a Z1B or will it cause clutch slip. Anyone used this.

Have used part synthetic or semi synthetic before and it's worked ok, even the car stuff. It's gotta be good coz the oil in the seventies (mineral 10/40) cant be as good as newer semi syntetic 10/40. Dont use the car full synthetic as it will make your clutch slip. Only the bike full synthetic is ok

Thanks for that will stock up on a few gallons Ha Ha
