Replying to: ruking1 (Jun 14, 2009 2:31 pm) As I understand it, Redline and Royal Purple are not PAO based oils, they are instead Ester based Group V oils. Do you know of some late breaking information that would contradict that? Best regards, Shipo |

Here is a excerpt from Royal Purples own web site: ..."So what makes Royal Purple’s synthetic lubricants so good? Royal Purple is ‘manufactured’ in chemical plants. Poly-Alpha-Olefin (PAO) bases are most commonly used in synthetic lubricants. PAOs are similar in chemical properties to extremely expensive pure parafinic mineral oil but contain no sulfur, no phosphorus, and no metals."... ..."Royal Purple’s performance advantages come from a blend of synthetic oils plus Royal Purple’s proprietary Synerlec technology."... link title Redline also does not leap out and say 100% NON PAO... or even 100% Polyol (Group V). So if you tell me Redline and Royal Purple are 100% Group V, Polyol , truthfully I have no reason to doubt your update. My take is it is probably a propriatary blend of group IV and V. So for example the Mobil One 5w40 I spoke of is ( 26 per 5 qt. vs $40 per gal Redline ) per qt 5.20 vs 10. aka 100% PAO IV base stock. Since I run 25,000 mile OCI's, would the 2 x expense of Redline allow: 1. either 50% less the wear 2. and/or 2x the OCI or 50,000 miles 3. or both?

Replying to: wtd44 (Jun 16, 2009 8:49 am) On first glance it would appear the current web site does a great job of product marketing. I noticed an almost systematic total lack of the normal "oil specifications." In line with the threads' current discussion, I was a bit amused, perplexed, etc. Years ago their web site said "words to the effect "that the Redline product's were indeed BETTER than the oil specifications in a specific product application. They were NOT technically certified to meet or exceed the oil specifications but their their R and D indicated they were far superior to almost any competing product (like Mobil One) They if I remember correctly, concluded they would rather invest their monies in R & D rather than for the right to wear (those stinking) badges....  ..."Red Line's motor oils and gear oils use superior ester base stocks that provide extreme stability at high temperatures and superior film strength at lower viscosities where more power can be produced."... So in some sense the current web site appears to be preaching to the choir so to speak. However when it comes to real world results there is a decided lack of VOA's and UOA's on the after market. So for example on a niche market specfication VW 504/507, I know of almost no one who uses it (Redline 5w40, 15w40 (diesel), for that application, let alone has a UOA. ..."Calculated by dividing total wear metals by miles in thousands. The national average is 6.538 ppm total wear metals, less Mn and Ni. This is based on 51 ppm total / 7800 miles by Blackstone. TDI Club Ave : 6.614 ppm. ~~~~~~ Club Ave. OCI : 9808 mi. 5/19/09"... link title So for example 50% better would be AVG: 3.307 ppm total wear metals... I have no doubt that because of limited production of PAO V's (aka Polyol Ester), the cost is probably factorially higher than PAO IV, and certainly (hydrocracked) group III the stuff Castrol calls "synthetic". |
