How do you replace the oil yourself?
Typically I'll let the dealer do the first 3 or 4 oil changes, If there is something that is going to cause a warranty problem with Honda it will be some rare thing that happens with in the first 15000 miles, if there are no problems then it's going to be along time after the warranty goes out before something major goes wrong.
After the 3rd or 4th oil change I do it my self because it is quicker for me to change the oil, rotate the tires and look it over than it is to drive to the dealer and wait. I do take pictures of the odometer and the old oil filter for records just in case.
Sorry I have to rant here,if your like me and don't like to here people complaining stop reading, I know I did, but my fingers are still typing.

I have never trusted dealers anyway, I have had one striped drain plug on a 90 Honda civic, The dealer tried to claim that It must of happened at a quick lube place, I told them to check there records, they did the last one. I had to wait while they replaced the oil pan. I wouldn't of minded there error if they had of just emitted it and not tried to shift the blame.
On my Subaru Baja the dealer over filled the oil by more than a quart and a half to the point it was foaming. The N/A Baja holds 4.5 quarts with filter I took in my own 5 quarts of Mobile 1, where did the other Quart come from:-?
Called the dealer and they said it will be OK, I said the oil was foaming, they said not to worry. Then I discovered a light scratch on the hood that must of happened with there free had car wash with oil change, dirty sponge or a piece of jewelry must of cause it .
There is a lot more but I'll stop.
Complaint over sorry:-|
