Question: The exhaust pipe has black oil in it and it smokes

I think I saw a few drops of water dripping from the exhaust too. I am planning on putting Amsoil in it. I am hoping this will greatly help.

The water is normal unless you have lots of white smoke. If the exhaust is black from soot on the inside, that is pretty normal too.

If you have blue smoke with the smell of oil burning, then you need to have the engine checked. You may have an oil consumption issue. Using Amsoil will probably not do much for this issue.
