Engine Oil

My car is due in for a service, and I plan to bring my own oil. I rang the dealer and told them I'll be bringing some 5W40 oil with me for the service, but the service manager told me the car needs 5W50 not 5W40 grade oil :huh:

I checked with the manual, and it clearly states that 5W40 grade oil should be used, what should I do? :shrug:

Clearly I'm going to use 5W40, just curious why the dealer would insist on using 5W50 :shrug:

Could it be because of the local weather here? Hong Kong is pretty hot and humid...
