So, why isn't the s2000's superior oil filter used by the rest of the Hondacura fleet? cost? Why didn't Honda's long engineering test find those power steering and transmission issues?
As long as you use a full synthetic, there really is no thick/thin argument here. So, use a full synthetic 5w20 or 5w30 and follow the oil life monitor for changes.
But, since you said you wanted to keep the vehicle a long time, make sure you change it at least once a year or every 10k miles since I still don't have full faith in OLM or any OE engineering.
And, don't forget to maintain the transmission too. Pick an interval more aggressive then what the owners manual states and stick with it.
