SYNSKEPTIC wrote OK. How can this lubricant handle engine contamination by-products over such a long period of time? Every mile driven is going to contribute some contamination products, mainly unburned fuel and moisture. If the lubricant is inert it will not combine with these contaminates, but they will remain and accumulate in the crankcase.
SynLube's ability to last for so long is based on it's superior ability to seal at the rings much better than conventional lubricants. This is because the solid lubricants are embossed into the walls of the cylinder so the seal is almost perfect. Unburned fuel is not a problem in any engine that is in repair. What unburned fuel is left after combustion is exhausted rather than being allowed to seep past the rings. Remember that even in the most mundane engine, the air-fuel mixture is traveling at hundreds of miles per hour. In a high-revving engine, the air- fuel mixture reaches close to supersonic speed. Unless the rings are broken, almost nothing gets past them. Also, keep in mind that gasoline evaporates and is eliminated from the system by the crankcase ventilation system even if the engine isn't running.
SynLube's ability to handle moisture is unsurpassed because it doesn't respond to it. Besides, a single drive of 10-15 miles will purge any water from the crankcase system. As with gasoline, water trapped in the crankcase will also evaporate through the crankcase vent system.
It is beyond the scope of this forum to go into a full discussion of the merits of this lubricant. I suggest going to the website and reading the information. If you do, leave behind all the indoctrination conventional lubricant companies have spent millions training you to believe. SynLube lubricants are a different ballgame.
I have been using their products for close to four years now and they work day in and day out.
