I have a 04 E320 and the oil filter cap will not budge.
First tries i did by hand. Do I need to use something more?
It being plastic I did not want to force it.
I will be changing my own oil in the next month and wanted to get a head's up

Also, I noticed Peach parts has 5W40 synthetic oil and not the Euro blend this car calls for.
Is that a dealer only oil???
