2006 Ford Fusion SE automatic front wheel drive.
Entire circumstances of problem. I Changed the oil in my 2006 3.0 FORD FUSION SE after Jail. It was definitely due for it. My sons mom drove it while I was gone and she drove it for a little over 10,000kms without doing service or work to it. Besides making sure it had fluids ex. power steering, brakes, transmission, engine oil, and gasoline. It definitely needed some love when I got back. Before I changed the oil I noticed that the bottom of the car was covered in some type of oily substance but yet it didn’t burn hardly any engine oil unless on a very long road trip then I’d have to add maybe 1/10th of a 1 litre on return from the trip. It still runs really good. I almost hardly have to add oil to it. After I changed the oil and the filter and the drain plug as well as the drain plug gasket. The car got this almost acidic burnt kind of smell and it’s now louder then ever. I’m also going to let you guys know I did get distracted by something else and I looked away and ended up spilling a generous amount of oil when I was refilling it and some went right into the alternator before I realized i was spilling any. I did my best to wipe it up with rags at home. I do live in the country and I don’t have a spot on my house to hook up a water hose so I figured I’d just drive it to the car wash when I got time too. Anyways I washed it at the car wash motor and underneath and it still didn’t get rid of that smell so Im thinking it’s the oil pan leaking onto the exhaust or the led headlights+anti flicker adapters I added after the oil change. But why would it smell so acidicly burnt and why would it start smelling that way after the oil change was done and not before? Help? Oh yeah I forgot to say I did the oil change twice to flush the motor after not doing it for so long. The first time I used the cheapest stock oil filter Canadian tire had for the 3.0 fusion (moto master) I think it was. I drove it for maybe 2-300 kms then did the change again using Canadian tires most expensive stock oil filter the extra guard one.
