Amen to that; +1 ! You've got to have your head examined if you deliberately deviate from what is specified !What evidence do you have that the Honda engineers made a mistake on the engine oil for the engine they designed??
0W-20. The 15/16 FK2 has the same motor as the upcoming CTR.will be interesting to see the oil spec for the R.
WRX and STI call for 5w30 and will generally break down to 5w20 after a few thousand miles. If the upcoming CTR calls for 0w20, will it break down to 0w10? Are Euro oils more robust?Use the proper weighted oil - especially in cars with variable valve timing. The FK2 CTR's 2.0T requires 0W-20. If there were any concerns about viscosity or thermal breakdown, it would have been addressed there.
0W-20 has better cold start protection and is backed by over a decade of UOI's. Stick with that oil unless aftermarket mods call for something thicker.
Just curious, why is this an upgrade? Wouldn't 0-20 give you better fuel economy and less drag? I truly would like to hear you opinion. Sounds like a downgrade to me.Dumped the factory fill @ 3,677mi. and refilled with regular Mobil1 5/30, no more cold start rattle and truth be told much better protection from wear and especially heat. Can clearly hear the difference, very cool. I will be running a UOA on this but being fresh it may take til January for the MM..will keep everyone posted.

PS You're deluding yourself if you think you "Can clearly hear the difference," Use oatmeal and you'll really be able to hear the difference.Page 492 Owners Manual :
"You may also use synthetic oil if it is labeled with the API Certification Seal and is the specified viscosity grade"
What part of "0W-20" don't you understand ?!
Please translate; just curious : what's the 0/20 CAFE sheeple spec that you don't honor ? and what do you mean oil the top tier fuel for what good reason ?My toys are oiled to the max, no 0/20 CAFE sheeple spec honored..even oil the top tier fuel for very good reason.
Yes, Euro oils are held to a higher standard. But I'm willing to bet the CTR's 2.0T runs tighter ring clearance than its competitors. Less fuel/contaminants slipping past the rings equates to longer oil life.WRX and STI call for 5w30 and will generally break down to 5w20 after a few thousand miles. If the upcoming CTR calls for 0w20, will it break down to 0w10? Are Euro oils more robust?
Just find it pretty odd that a high HP small displacement motor would call for 0w20. The RS requires 5w50.
