I tell him it says 10W-30 in the manual. He says " I know but they are telling us to use 10W-40 now." I question him a bit further. He is adamant. I buy the 10W-40. Driving home I'm thinking "who should I be listening to, the engineers in Japan who designed this bike and fully understand the difference between 10W-30 and 10W-40, or some kid in the parts department?" Either the engineers were wrong or oil has somehow changed or...
Does anyone have any insight or opinion on this? I'm thinking it is not a big deal and don't feel like driving back to exchange the oil so I'm going ahead with the oil change, but thought I'd check in with you all anyway.
Thanks!

Hsving no insight on which oil will work best in the CB1100 engine,.my 2013 Honda runs well since the 1.000km inspection with 10W40 half synthetic oil. The Honda dealer used it and I stick to it ever since over 45.000km. Of course I led the same debate with him asking for reasons why he is doing so and the manual is telling something different. He explained, if a Fireblade is running with 10W40, why can't a CB? That comparison was not so fitting, 'cause on the one you have a watercooled high reving sport engine on the other an aircooled motorbike with a somehow modest layout.
Nevertheless I keep to this specification and til yet it did the Honda no harm, not even showing signs of any oil consumption between oil change intervalls. I don't rev the Honda 'hard' and let the engine warm properly up on each ride, but do the change thing only every 12.000km instead of Honda's recommendation of 6.000km.
