Oil is not draining
Oil is not draining Last time I changed my oil, it seemed like not very much drained out but I thought it was just in my head.
I only added 5 quarts, then I was going to wait a day and add more oil in until it was at the full mark. When I checked it, it was way over the full mark even though I only added 5 quarts.
I'm changing it again now, and it seemed like it didn't drain much again. So this time I checked the dipstick before adding any oil, and it says that it is over the full mark even though the filter is still off and I haven't added any oil yet.

You have something blocking the hole inside the oil pan. This may get a bit messy, but pull the drain plug and then stick a screwdriver up in the hole and wiggle it around to see if it drains. Either way, you'll need to plan on pulling the pan to see what's in there. I've seen pieces of broken off piston skirt cause this.

If there is a Blockage, use a screw driver and insert, if there is anything that needs to be dislodged, oil should flow freely. I certainly at this point would have the motor up to temp not only in coolant, but in oil. So to eliminate any cold oil issues.
Also some people have the car jacked on one side and the oil drain plug pointed downward.

My arm got blasted with oil, but it happens. There was some sludge, but I did not find any metal.
Do you still think I should pull the pan?

I think I probably would...a new pan gasket is lots cheaper than a new engine. If you don't find anything but gunk, wipe it out and then flush the engine accompanied with a couple more oil changes. Get the GM engine flush and follow the directions on the can.

Absolutely right. Additives do nothing but dilute your oil, none of them add anything useful, and none of them do what they advertise. The only additives you need are already built into the oil.
The only exception to this is when the manufacturer tells you to add a friction modifier to fresh gear oil in your rear end.
