Folks, I am planning to do an Oil change (DIY). I am not new to this. I used to have Lexus, MB E320, Hondas, and I did all maintenance myself. So question as time has changed if I do service myself will it avoid the warranty. It has original and took an extended warranty. When I talk about maintenance I mean basic oil change, ATF, air filter, etc. I will keep the receipts of the filter and oil which I will get from the MB dealer. Please suggest

Thank you
