I'm quite disappointed with the service. I have 2011 Honda Accord and the only thing I did in the service was the oil change. And the oil was always overfilled. Honda manual says clearly that oil level should be between two dots on the dip stick. Every single time I check the level (I did it early in the morning on the cold engine) the oil level was above the upper curve on the dip stick, i.e. almost one inch above the upper dot.
Yesterday, on Feb, 6th, I visited the service and showed them this problem on my Honda. Service managers were very polite and gave me excuses saying that they would fix it. Managers returned me the car and told me that they double checked that everything was done right. I checked the oil again today in the morning and it is filled right up to the upper curve on the dip stick, about a half of inch above the upper dot.
So, I assume that Honda owner's manual is not something I should trust in this case. Probably service guys know better how much oil should be in the Honda engine.
