Jim,
Please read through my post #5.
Your current 'peace and quiet' may only be temporary.
You can go into the [link=http://www.morganfuel.com/omega_main.htm]Morgan's Omega page[/link].
The CP you are using will keep you model cleaner, but will not be advantageous for the wellbeing of your engine, which is its main purpose, I believe.
If you insist on all-synthetic lube, you better get some fuel from Europe, with Motul Micro, or with Sachs Aerosynth II/III/Aurosave, or go to Brian at [link=http://www.cooperfuels.com/]Cooper Fuels[/link] and get the wear protection Ester based oil will provide.
