Andy, these tractors were built when motor oil was well.......motor oil. Most of what was available was NON-DETERGENT and that is probably what your "C" was raised on. When you changed to a synthetic oil it probably has detergents in it. Look on the bottle and see. Let me try to explain what is happening to your engine. The new oil with the detergents is removing all the sludge and deposits left by years of the NON-DETERGENT oil. As you know these engines were built with fairly loose tolerences. When the deposits are removed the tolerences actually become greater with engine wear, and that is where you loose you oil pressure. But hold on it gets better. That same old oil sludge that has been in there for all these years has also been stopping internal and external leaks. Now your engine has lost pressure and is smoking and leaking all over the place. If you continue to use the new stuff it will get worse. The sludge that has been sealing off the valve seals and the piston wear is leaving and oil consumption will increase dramatically. A friend of mine did this same thing in a 52 cub and it got to the point it looked like a brush fire in the field. Shortly after that came an engine rebuild because it fouled plugs left end right. I am not saying this is the only reason for the engine demise of the cub but, I have seen this too many times to not let you know the potential consequences. My advice to you is to drain out the new high tech stuff and find you some NON-DETERGENT OIL at a tractor supply store. Your local auto parts store will probably look at you and say "did you look over by the bug shields with the rest of the oil?". Remember to replace your filter element when you do this. Good luck. Dan.
