Bottom line: Do NOT change your oil before the first 5K miles of your new HCH (it even states this in the manual). After that, change your oil every 4-6K miles. Personally, I would just ignore that "Oil %" gauge...those things are made for grandmas that can't remember if they took their 6 pills for the day.

The only real question when it comes to changing your oil in your HCH is whether is it better to put Mobile1 Synthetic 5W-20 or just regular Honda 0W-20 in it. They used to make Mobile1 Synthetic 0W-20 (I used it in my 04 HCH), but they discontinued it about a year ago. Anyone know the answer to that question?
