Performed an early UOA on my PSD to rule out any fuel dilution preventing my ICP from going as high as it should. The UOA was done at a Speedco truck lube place on a Truck Check Analysis machine. I took the sample myself via the oil sample valve on my Oilguard bypass filter.
2001 Ford F250 with 7.3 Powerstroke Diesel.
100,563 miles on engine
approximately 1650 miles on oil.
OIL: Schaeffer's 9000 Supreme Synthetic 5w-40
Full Flow filter: Fleetguard LF3974 Stratapore
Bypass Filter: Oilguard 20 series.
Air filter: AFE stage-II with PG7 filter
Additives used: 8oz. LC; 4oz 132; 4oz ARX
Many Mods done, "should" be close to 350rwhp and 750 ftlb TQ.
Driven hard many times with equivalency of 15-20 1/8th mile passes done on this oil during a live tuning session.
Aluminum.......... Chromium.......... Copper............ 4 ppm
Iron.............. 7 ppm
Lead.............. 10 ppm
Tin............... Silicon........... 2 ppm
Potassium......... 3 ppm
Sodium............ Moly.............. 119 ppm
Water............. < .1%
oxidation......... 2 absorbance units
Viscosity@100c.... 14.8 cSt
Glycol............ None Detected
Fuel.............. < 2%
TBN............... 9.5
Nitration......... 2.0
Soot.............. 1.6 absorbance units
So there you go. The only thing that i wonder about is the LOW silicon. I know, I should be happy because it means good Air Filtration. The thing is, I have seen a Virging sample done by another person on Schaeffer's 9000 and the VOA had about 14 ppm of Silicon and there was a disclaimer that it was due to Schaeffer's having an extra amount of Anti-foaming additive. This UOA does not reflect that. Makes me wonder if I should get some of IH's Defoaming additive and add it to the oil to see if it eliminates the low ICP code I used to never recieve.
