I recently gone through a manual of Honda city where they also recommended 5W30 viscosity with older grade oils and it was not less than a surprise for me.
Anyway, Honda's own engine oils are being blended by Total.
And presently best fuel saving oil is Quartz 9000. Its 5W30 and SN grade. Its expensive, but change over time is long also upto 7K. But you must buy it from Quality shop.
As you own an expensive ride, so if you want to go for longer intervals, then ZIC XQ 5w40. Its SM grade but I will say its perhaps the top best quality engine oil available in Pak.
