Doron, You obviously know your stuff when it comes to lubricants. Thank you for the information, some of which I once knew but had forgotten. Your last remark is the focus of my question: Do you mean to say that there is some fundamental difference in the way Royal Purple (RP) motor oils are formulated as compared to Redline motor oils which would account for the reported observation that RP 5W30 sounded better than Redline 20W, other than viscosity? My point was that the difference in sonics observed the the OP might have been due entirely to the difference in viscosity between the two oils. Do you think yes, or no? It was after that when I made my ignorant remark about slow motor speed.
You must realize that if you say RP oils are superior to Redline for use in a typical TT, then at least several of us are going to run out and buy RP motor oil. I've got the Redline 20W in my Kenwood L07D. By the way, I'm not interested that much in "stop times". I don't know what it means for a tt platter. A very low viscosity lubricant (I can imagine) might allow for long stop times (at first) while also doing damage to the bearing in the process.
