I also add a couple of ML of a product called extralube ZX1 in with the fuel it's a metel treatment not fuel treatment! Zenoah say to change the piston ring after 8 hours of racing and mine is on about 25 hours with no drop in performance! easy way of checking if your oil is doing the job/and your not running to lean, after a good thrashing pop your exhaust off and look inside the head and look if there is a coating of oil on ya piston.
