Denny, due to the length of my post and trying to remember all the points to make (you can identify, can't you? ) I had intended to add a disclaimer to the Gibbs reference but "forgot". Now that you've reminded me here it is; As with most links I put up my intent is usually not to endorse exclusive use of that product/system/whatever, but to use it as a learning tool to be applied however the reader sees fit. There are certainly other products that will work as effectively, but you may not be able to identify them without some knowledge to aid your choosing.

If I remember correctly Gibbs has a sponsorship tie in with Shell. Very likely they are making the oil for him to re-market. As for the additives package in the base oil, there are only a small handful of companies around the world who produce oil additives so the technology employed at Gibbs is not proprietary to him. If you think about that statement, it would also be enlightening about the "snake oil" segment of the market.
