I actually think it can cause chunks of sludge fall off. Last year a friend of mine changed the oil in a 9n with detergent oil. That had never been used before. All the tractor was used for was to rake hay. It developed a bad knock after a couple days. He changed the oil again and he showed me all the crap that came out with it. The way I see it. Why chance it. If you have a old motor that has allways used non detergent. Keep using it. Something must be working.
