[QUOTE="UnleashedBeast, post: 11085969, member: 112023"] [b]Amsoil 10W-30 UOA results are in[/b] UOA chart updated yet again in post #1 I'm shocked at how fast the results are in. The sample was just sent off via UPS on Tuesday afternoon. WOW! Good job Polaris Labs. :thumbsup: [ATTACH=full]236512[/ATTACH] Lab technicians do not think sometimes, but I can't blame them....they don't know the vehicle as well as I do, and have to test so many samples, so I decided to clarify some things. Really? If you would look at the three previous samples taken from this engine, you would have seen that the silicon levels are declining after every oil change. This is due to the sealants used to assemble the engine, and not dust contamination from a faulty air filter. How can you make that assumption without a virgin sample from the same batch? This is the normal range for PAO synthetics. :dw: That's because you have the virgin specs for the old Amsoil 10W-30. The new signature series 10W-30 had a big change in the additive package. ZDDP was reduced, Moly and Boron were added to compensate. If they had the new specs...Moly, Boron, and Magnesium would not be flagged, as it's native to the virgin sample. Finally I have more solid proof that Moly and Boron is a great substitute for lower levels of ZDDP. Manganese is flagged for a good reason. This is what happens when you use Torco.

I'm very happy with these results, and so far are the best from any sample in the list, my previous samples included. Amsoil 10W-30 is dominating the performance in my engine, and the oil pressure in my car is slightly improved over 10W-40. I can only imagine the improvement over un-sheared 5W-50. :) Virgin Amsoil 10W-30 viscosity is 10.5 cSt...and it remained exactly that...10.5 (zero % shearing). TBN is still over 8, so that means this lubricant could be used for many more miles. Retesting when the car is slightly over 12,000 miles. [/QUOTE]
