The requirements of the rotary engine are the same for all models.
The oil type for the primary chaincase is also the same. Originally Norton specified 10W40 but I prefer to use thinner ATF or even hydraulic (fork) oil
Gearbox oil is the same for all models apart from the F1 which uses 20W50. Originally Norton specified 85/140 gear oil. I tend to go for a medium competition gear oil.
The table below is from my own notes and shows the quantities required on all models.
