Has anyone with one of these engines tried running 4 quarts to see if it's ok? If I had one of those engines I'd try to squeeze every last possible ounce of oil into it, as that specified capacity just seems so tiny!! I can't imagine those engines could handle long drain intervals with such a small amount of oil, it would degrade so much faster.
