I have about 34K miles on my 12. We get into these discussions about oil changes, do you follow the MM or not blah blah blah.
A "friend of a friend" of mine has an independent shop where a 2009 came in with cam issues, probably due to lack of oiling. From what I hear, the vcm shuts off 3 cylinders on one bank, and if you drive with it on for an extended period of time, the idled bank starves for oil. This is probably why Honda switched of 0w-20 in 2011 or 2012 from the 5w-20. Now, you have a school of thought on here that says run it until the MM is at 20%, no less than 15%. At 30K, I made the decision that I will change my oil at every 5k, regardless what the MM says.
In my opinion, keeping fresher, cleaner oil could help from whatever is causing these oiling issues(sludging?), and while I won't do the VC muzzler, I drive it in such a fashion so as not to go into VC mode for extended periods of time(i.e., I drive between 70&75 MPH) on the highway. So between oil changes at 5k, HondaCare 8/120, and NOT letting the old lady drive it much(reducing the possibility of going into VC mode), and every once in a while, really kicking it in the ass, I think I'll be ok.
