There seems to be alot of debate regarding what grade of oil we should use in the S2000.

The dealers seem to put in 10w/40 however other forum members seem to use different grades.

I have some 5w/30 to put in mine however i am thinking about sticking with 10w/40 which i believe Honda is reccomending.

There is no need for debate.
The owners manual gives a guide.
You use what fits your climate.
Simple as that really

Whatever the Honda muppets put in it at the service.

Castrol Edge 5W-40 for me and HWMBO

0-30, 5-30, 10-40 and 5-40 will all suffice. There are a few others that have been used with good results.

I use Comma SYNER-G 5W-40 FS.

I bought the car new from Fish Bros in Swindon, who advised, "after it is run in, use nothing but 5W-40 fully synthetic".

As I live in Welwyn Garden City I have used Brayley Honda for all services since the first (free) one, and when I asked them what they use they said, "5W-40 fully synthetic".
