zinc out and added lots of detergents. As you well know
zinc is what bonds the oil to the metal and the high ppm detergents wash the zinc away. This works great for late model stock engines with overhead cams and low spring pressure. Bottom line, make sure there is plenty zinc in the oil to save problems in the future.
