I doubt the lack of the oil change caused this problem unless the fuel issue you were having was a bad fuel pump and it was pumping gas into the crankcase and diluting the oil. Other than that old oil will generally not cause issues with relatively low mileage on it. I was thinking along the lines of an oil pump failure, I have seen that a few times in M-151's. Usually it is the relief valve spring breaking.
