Went back to my dealer today to get my free oil change on my 2007 Sonata I4. The invoice shows that they used 10W40 oil. The manual states 5W20 recommended with 5W30 and 10W30 being optional, nowhere does it say use
10W40. The invoice shows 4 qts and the manual says 4 1/2 so I checked it to make sure it wasn't low. It doesn't have a line crossways to indicate full but it does have a indentation (like a punch mark) with an "F" further out (higher). The oil is about an quarter inch higher than the "F" which looks to me to be over filled. About a hour after I got back home, my wife came in and told me that oil was leaking under the car. Oil was leaking from the back end of the plastic under cover plate where it must have got caught when they changed the filter. I put a newspaper and a brick under the car to catch the rest until I can get out tomorrow and clean it all up. I don't think I will be taking it back there for any more oil changes. 2 questions 1) Does anyone think I have too much oil? 2) Is the oil catching on the cover plate a common problem and how do you avoid it? thanks- posted
