I checked my dip stick and was halfway. Til I saw oil spot in the driveway front driver side. Wiped up excess oil underbody and looked for heavy saturated areas found a electrical plug heavy coated Don't know if that's the sending unit where leak is coming from to the left of the oil filter. It's dark now can take a picture in the morning.

A picture will help. However, this could be the oil pressure sender.

I am attaching info on this below to see if this is where you are seeing this oil coming from.

However, what we need to do is clean everything off and then add an oil dye to the oil and that will help us find where this is coming from.

It is not required to change the oil, but it is a good idea and then add the dye.

Then you just run the engine until you see the first sign of oil on the engine and then shut it off. You don't want to wait too long because if there is oil all over then it will have dye all over and that is not going to help pinpoint where it is coming from.

Please see the info attached of the sender and let us know if you can get that picture and we can go from there.

Thanks
