That sounds a bit heavy to me Simon, I run 20W/50 in mine and if I were ever to change I'd be looking at thinner oils not thicker. I've only ever used engine oil (either 20W/50 or straight 30) in the gearbox and have no plans to change.
In Australia the original engine oil recommendations were SAE 30 winter SAE 40 summer .
As far as i know the Penrite designation 20w/60 officially doesn't exist- I would think they should really call it 20w/50.
They say it replaces their original SAE 30 oil - not sure of the additive package but I think they are suggesting it performs like an SAE 20 when cold and an SAE 60 when hot.
