Oil Change day. Started great. The drain plug was not seized to the pan and the filter was not too tight to remove. But once I got the drain plug out, everything got ugly in a hurry.
Instead of a stream of funky old oil oozing out of the drain, there was a gusher of gas smelling, almost water thin black liquid. And a lot of it.
The oil pan should hold 4 quarts and the filter should hold another. When I drained this crud out of the pan, I got 7 liters out. I know it is 7, because I had to put it into three, 3 liter Dr Pepper bottles, since it was overflowing my oil drain pan. Filled two bottles and 1/3 of the next. 3+3+1=7, see.
I don't know what caused this, could it just be really old oil? Could it be bad engine parts? Other ideas?
