My daughter came home from college for the weekend so I thought I would change the oi/filter. Opening the hood I saw oil sprayed on the passenger side of the engine compartment.
Looking with a light I could see the serpentine belt had oil on it too. Checking the oil dipstick I couldn't see any oil.
I didn't notice anything unusual looking underneath the car nor from the top of the engine compartment with a light.
I'm taking it in Monday to an indpt mechanic. Hopefully nothing serious.
I've had the car since new (Nov 2012) and with 120K miles its been trouble free so far.

Did anyone check the oil and not put the dipstick all the way back in?

Did someone add oil?

Did someone loosen the oil filter?

Is the drain plug secure?

Has there been any damage from road debris?

Those are the first things I'd be looking for.

I last changed the oil.
Dipstick was in.
No one added oil since I last did the oil change
The drain plug seemed secure (by hand)
Couldn't see any damage from road debris.

Mechanic said he didn't replace anything as he couldn't see any oil leaking after changing oil. Hes had my car three weeks test driving it to verify issues. He put red dye in oil before changing oil but couldn't see any signs of leaking.
I'm stumped as to why there was oil leaking in passenger side of engine and why I needed to put 2 qts of oil to get it to full.

Son of a gun! It happened again. My son was driving the car and the battery light came on. The serpentine belt slipped off because of the oil leak on the passenger side.

Send nudes pictures of the engine bay and where you think the oil is coming from. Not sure I personally will be able to help you out because but there are a few people on here that really know their stuff.

I read another post where someone replaced the crankshaft seal and that fixed the problem. The car is not in my possession

They sell ultraviolet dye detection kits for every fluid in a car. You will be able to detect even the smallest leaks with one. I've use one for A/C leaks and coolant leaks. Saw the dye in the oil in my old '03 3.1 that I put in the coolant to confirm a intake manifold leak which they were famous for.

Well supposedly the mechanic that I trust put the dye in the oil last time I brought it in and couldn't find the leak.

My son took the car into a mechanic this Monday. They couldn't replicate the leak and were going to put the belt back on and have my son pick up the car. I called the mechanic and said not to put everything back and to just replace the crankshaft seal and harmonic balancer.
The following video explains what most likely happen to my car (now my son's car). Same year and model as my car.

That guy did an awesome job. Real inventiveness when making that spring compressor!
