The detailed results of my last oil sample sent to Blackstone Labs:
'03 Nissan Sentra Spec-V QR25DE 2.5L 4-cyl
Schaeffer 5W-30 synthetic blend
Hastings LF240 filter
5,009 mile interval (April to August)
Current mileage on vehicle: 22,612
No make up oil used.
Notes from Blackstone: ". TBN = 2.3, vs. 2.5 last sample. Client's (Terry's) comments being e-mailed direct to you. Note barium (additive) in this oil."
The following are my parts-per-million readings.
Schaeffer / Red Line / Universal Averages:
Aluminum 3 / 8 / 3
Chromium 1 / 2 / 1
Iron 14 / 23 / 10
Copper 8 / 7 / 5
Lead 4 / 12 / 3
Tin 0 / 0 / 0
Molybdenum 139 / 278 / 72
Potassium 0 / 0 / 6
Boron 1 / 15 / 47
Silicon 12 / 15 / 12
Sodium 4 / 17 / 7
Calcium 1857 / 2348 / 2128
Magnesium 4 / 7 / 230 (Blackstone error?)
Phosphorous 781 / 1077 / 821
Zinc 943 / 1122 / 994
Barium 57 / 14 / 2
Flash Point: 385F (should be above 355F)
Fuel: less than 0.5% (should be less than 1.0%)
Sustained viscosity @ 210 60.6 (should be between 53 and 62)
Antifreeze: 0%
Water: 0.0% (should be less than 0.05%)
Insolubles: 0.4% (should be less than 0.6%)
All other values (for rare metals) not listed above are zero (0)
I'll have some comments / interpretation of the above in a bit ...
