Blackstone Labs:
This samples shows 2ppm of iron, whoch could possibly be from corrosion in a storage or transfer tank or other handling equipment. This is a common find in virgin oil and not a problem. The TBN was strong at 10.2. TBN readings usually start out arounf 10 to 12 and decline as the oil is used, showing that the additives are being depleted. If the oil is run for a long extended use, the TBN can get down to 1.0 or lower, which is considered a low reading. Molybdenum is an anti-wear additive, same for zine and phosphorus. Calcium is a detergent/dispersant additive.
Iron: 2
Molybdenum: 192
Calcium 2797
Boron: 5
Silicon: 5
Sodium: 1
Magnesium: 7
Phosphorus: 634
Zinc: 753
SUS Viscosity @ 210F: 64.6 [High end of 10w30]
Flashpoint: 430F
Fuel/Antifreeze/water/insolubles: 0 (as expected)
Well, the Valvoline Synthetic Maxlife is very similar to my UOA of Castrol GTX Highmilage 5w30.
Going solely by flashpoint, I'd have to say that this oil appears to actually be a synthetic base (POA or Ester), or have some REALLY good additives to prevent burning.
Thoughts?
