[Gold Digger]

I am real familiar with steam cylinder oil from owning and operating steam tractors and engines over the years. Regular 90 or 140 wt oil will not lubricate steam engines as steam will wash it away. I'm not very technical on oils but I know that a steam cleaner won't start to clean 600w off of a steam engine. The only way I have had success cleaning it off is to wash with kerosene and scrub real hard then use a steam cleaner. That's how hard it is to brake down. Worm gears also call for 600w lube.
