I have beenn underneath theChrysler 300C w/ my boyfriend and we cannot find the place to change the oil. It's not like we haven't done it before on other cars so where is it. Can someone tell me how or send me a diagram of the undercarraige?!?! Please help.

 

Remove the 4 screws that hold the plastic shield on. Its right on the bottom side of the engine. You can't miss it. If you or your BF do,then I suggest you get a new BF.
