First time I changed the oil on my new 2014 ford fusion, I put it up on the ramps , slid under, and said "what the he**, I can't see the engine." Then realized there is a cover that has to come off, that covers the whole underside of the engine and is held on by I think 12 small screws. My question is, do I really need this cover, or the next time (probably spring) I change oil , can I just leave it off?? Is it there for wind noise abatement, gas mileage increase, or is it suppose to protect something? Although it is just a heavy fiberboard. I have been crawling around under car for 50+ years, and Never saw this before, of course my last new car was in 2005. It seems like an extra pain to me to have to r+r this cover all the time, even though I only do it 2 times a year.
