Recall from HONDA

[Cormanus]

I think you’re reading that right A-man. I wonder if Honda’s now recommending using fully synthetic oil?

Be interesting to see the section of that manual for recommended oil

I'm on holiday, but I'll check when I'm back. Remind me if I don't.

From the top of my head, i think they recommend full sinthetic oil. 10w-40.

Jtopiso: Be interesting re synthetic, as the older manuals only indicate API SG or higher and no "energy conserving" or "resource conserving"...which would be a clutch slippage issue.

API SG or higher. SAE 10W‐30, JASO T 903 MA
Don't use "energy conserving" or "resource conserving" oils.

I think the "MA" spec is the important thing for the cluth slippage.
Synthetic 10w-30 is what the engine cares about.
