Joel,

Here's something I found from "JackD"....


----------------------------------
Do not use oil containing MOS2. (Molybdenum Sulfide)
Although molybdenum sulfide is a very good lubricant, it is a solid (powder) and never dilutes in a liquid (oil). Some of the small oil passages in your engine can get clogged with the stuff.
Having worked in the oil business for a major oil company for all of my adult life, testing, comparing, blending and developing lubricants for major engine manufacturer, I can tell you that a good brand of mineral oil is all an engine requires. There is nothing wrong with high-end (price) synthetic but for most normal application, you are wasting your hard-earned money. I must say the oil comanies have done an extremely good job at marketing their high prices synthetic oil on with they make a very high profit margin.
I sometime compare using synthetic oil in a engine to washing your car with chirurgical certified grade distilled water. It does the job, but at what price?
