Main issue is, that you can't drain much more than 90% of the oil from those engines. The sod in the old oils is so strong, that will stain new oil right after first start up. I do have older Perkins engine in my welder, that keeps the oil clear for hours after change, but no oil cooler and straight 3-cylinders.
