[QUOTE="UnleashedBeast, post: 13297378, member: 112023"] Here is more evidence that Royal Purple is now using hydrocracked petroleum in their formulation. The 1 year report is back from the test car, 2004 Lincoln Town Car. Sample #1 - Amsoil Signature Series 10W-30 Sample #2 - Royal Purple non-HPS 5W-30 [IMG]https://sphotos-a.xx.fbcdn.net/hphotos-ash4/375617_579468042100040_68758726_n.jpg[/IMG] Let me get to the point. Notice in red, Oxidation. Any PAO based synthetic (lower blend of Ester) will read in the ~52-58 range. Cheaper base oils (not true synthetics) will read in the 20's. I've seen synblends register in the high teens. The performance in both lubricants tested in this 97K mile engine are close. There is nothing to bark about in wear metals, but it's easy to see that Amsoil Signature Series has a far superior additive package. Moly, Boron, Calcium, Zinc, and Phosphorous are all at higher concentrated levels. When you consider that you pay $9.xx per quart for Royal Purple off the shelf, it doesn't look as appealing when compared to Amsoil SS. Especially when preferred customers can buy it at $7.85 per quart. I'm also not fond of RP's choice of high Sodium PPM. This can be easily confused as a coolant leak. All the recent RP UOA's are showing this. [/QUOTE]
