Well this was my first analysis, and wow I must say I'm very impressed with the turnaround time with Blackstone!!
My truck is a higher milage truck with 376000 kms on it. This oil run lasted 2 months and was a little more unusual than most as 2000kms of this was put on driving from Vancouver to Calgary, Edmonton and then back home (all in 4 days!!! w00000t family marriages lol). So the first part of this interval was relatively easy. Knowing this, I decided to run 1000kms more than I usually do and then get it sampled. I would guess that my driving is typically 70% city and 30% highway. I maintain this truck very well with more than regular tune ups and fluid changes etc. This truck has been in the family since new and has always been maintained this way!
Okay, now that all that is out of the way, lets get onto what the analysis was!
Mileage on Engine: 376,250kms
Miles on Oil: 6,250kms
Sample Date: 05/21/10
Makeup Oil: 0
Aluminum: 2
Chromium : 0
Iron: 4
Copper: 2
Lead: 10 - this was in Bold, should I be worried?
Tin: 3
Moly: 58
Nickel: 0
Manganese: 1
Silver:
Titanium: 0
Potassium: 0
Boron: 41
Silicon: 15
Sodium: 30 - this was also bold, see comments below
Calcium: 3071 - why is this so high?? avgs are 2233
Magnesium: 12
Phosphorus: 696
Zinc: 880
Barium: 0
SUS Viscosity @ 210°F: 59.4
cSt Viscosity @ 100°C: 10.05
Flashpoint in F: 420
Coolant: ? - always worrisome when there is a known head gasket issues with these trucks/engines!!
Fuel: Water: 0
Insolubles: 0.3
TBN: 5.4
Their comments were:
For an engine with 376,250 miles on it wear certainly looks good. Lead was a little high but that's more likely due to a particle streak running through the bearings rather than from a developing problem, as all other wear read normally. We found a little sodium in the sample, which is likely from an
additive in an oil run in the past. With no potassium in the oil we doubt sodium is from antifreeze. Universal averages are based an oil run of 9,000 km. Try that next time. The TBN read 5.4 so you had more than enough active additive left. 1.0 is low.
Thankfully I'm not losing any Antifreeze, so I'm glad to hear of their doubts!!!
Anyway, if anyone can chime in here and comment, I'd love to hear from you!!
