Does it have a turbo? If so, that would be the easiest thing to check. If not, or if it is not the culprit, you get problems like worn cylinders, holes in pistons, broke rings, and worn out valve guides. I have seen extremely dirty air filters cause oil consumption, but not to that magnitude. Is the engine running smooth or does it sound like it is missing?

Yanmar, hours unknown, no turbo Running, it sounds no different than when I bought it.
Make sure it is oil you are seeing. You could have some rain water in the muffler that will mix with soot and look like that. Also, it could be antifreeze. Does the engine put off a blue smoke or possibly a white smoke? Do you get any hint of a sweet smell when it runs?

He could be correct...

Oil but no smoke? Makes no sense. In addition to the earlier suggestion, I would look for an oil leak somewhere higher, perhaps around a valve cover gasket that's finding it's way down the outside of the engine, making it look like it's coming from the exhaust.
Oil from worn piston rings creates blue smoke while antifreeze from a leaking head gasket creates white smoke.

No smoke at all. I found a tiny hole at the bottom of the muffler where it's coming from. It does not feel oily. It is located down here in Oakwwod TX. The leak is not coming from anywhere else, that was the first thing I checked.

If the hole looks like it was caused by rust, it could be coming from years of carbon buildup in the muffler that's somehow catching moisture, perhaps when the engine is first started. I would lean this way if the buildup shown in your photo is something that has been growing slowly over some time.
I would think that if it is an oil leak, perhaps with one of the valve stems, you would see the oil level drop over time.

Looks like dried soot to me especially if it does not feel oily. Hey, good excuse to get a new tractor!!!

I remember someone once saying that if an old tractor doesn't have a leak somewhere, you're not using it.

Hetman, it is not going through any more oil than before. I am now thinking it is soot spitting out that pin hole mixed with moisture. It is not dry soot for sure but not a slick oily texture to it. I'm just not sure where the moisture is coming from. Coolant level is normal. A new muffler is $90, or I could just look the other way.

Vertical mufflers on equipment will have a hole in the bottom to let moisture out. Over time mufflers will become caked up with soot and some amount of oil. I would run it and not worry. Just check the oil and antifreeze before each use like usual, and I bet you will be home free.
I would replace the old muffler before it bursts into flames and take your tractor with it. You have a grease filled carbon embedded ticking incendiary time bomb on your tractor.
Gary, because we talked about our old tractors the other day, they have to do something to scare us a bit.
No kidding. I was pretty down about it at first debating what comes next. I have since realized it is almost guaranteed to be a decades old muffler with an enlarged hole spitting soot and condensation. About a year ago I ducked under a mostly downed tree, the exhaust pipe did not. I ignored it until this weekend when I gave it a tug in an attempt to semi straighten it. When I heard/felt it give at the bottom, I immediately stopped and continued to ignore. Hours later I saw the black crap and panicked. I doubt that ole girl will make it til I retire but she's still a good mule for now. I worked her for the first three hours of daylight today and nothing is abnormal. Good Grief it's hot and humid at sun up. Did the AC work good after your efforts on yours?

I can't remember all the times I've helped someone troubleshoot a problem to the point where I had just about given up trying to identify the source. Then the person says something like, "Oh, by the way."

Does it have a breather to vent crankcase pressure? If it is plugged up, that will cause oil to leak from filler tube or dip stick..
