Since we are on the topic of oil changes...I notice some of you mentioned using 5w-20 or even switching to 5w-30. The new "06 HCH recommends 0w-20 but says you can substitute 5w-20. Anyone have any luck locating a store that sells 0w-20 motor oil? I have been looking around and have had no such luck. Have been told by some stores(Autozone) that it is not a quick selling item so it costs the store money to stock their shelf with it rather than another product that will sell. Also, are there any differences between Honda's oil filters and any other brand(eg. Fram). My salesman started to metiuon something about a crush washer rather than a gasket, however we got off the topic before he could fully explain it to me.
