[QUOTE="UnleashedBeast, post: 11081915, member: 112023"] Since reading your post....I went into work mode. So here is what I have come up with. Is it odd that Royal Purple no longer provides detailed product specifications after their line up reformulation? :??: I wasn't able to find anything other than MSDS information. Mobil 1 doesn't formulate a 40 grade lubricant in their Extended Performance line, but that's OK. Their mainline 0W-40 is a true synthetic, so we can use that for reference. I even suggest it to the lubricant buyers who insist to buy off the shelf. I do have a VOA on Amsoil 10W-40, Red Line 0W-40, and Mobil 1 0W-40, but no VOA on Red Line 10W-40. I do have product specs from Red Line's website for their 10W-40. Amsoil 10W-40 VOA: No moly or boron, as it uses the tried and trued method of ZDDP, and lots of it. Nice TBN as well. This stuff will retain the viscosity throughout its usable change interval. My previous sample sheared less than 1% after 4,124 miles. [ATTACH=full]235987[/ATTACH] Red Line 0W-40: Heavy in moly and esters. Red Line has always been a great lubricant. Lower TBN, but higher ester content is said to make up for this. It may shear slightly, but not much. Esters are very shear resistant. This VOA shows the viscosity to be about .87 cSt higher than the spec sheets gives. [ATTACH=full]235988[/ATTACH] Mobil 1 0W-40: Low in ZDDP, but makes up for it in moly and boron. This is the direction Amsoil Signature Series lubricants are trending towards. I was expecting ZDDP levels of around 1,000-1,100. That's what Mobil 1 specs this lubricant at. This isn't the first time Blackstone measured ZDDP low, sometimes I have even seen TBN measured higher than other labs. Very nice TBN (detergent/anti-acidic additive content measurement).
