Getting ready for the first oil change on a new 300C and have done all of my own routine maintenance on my vehicles since 1961. When I crawled beneath the car I noticed that there is some sort of plastic "splash shield" that covers the entire undersurface of the engine and that the oil filter must be somewhere above that splash shield. Is it possible to remove the back two retaining screws and allow the splash shield to drop down enough to get access to the oil filter (while laying on my back beneath the car) without placing the car on a service station lift? [Never thought there was a need to crawl beneath the car before it was purchased] MikeSp
