We know you have posted your results elsewhere in the Forum. Now there is one place to look for oil analysis and related commentary. Encourage you repost results if you want, all new test results here please. Thanks.
i don't understand your report. Time on unit and time on oil is in hours. For most tests the number is the same for time on unit and time on oil. One test has a blank for time on oil but has a number for time on unit. Another has a blank for time on unit but a number for time on oil. I would expect the time on unit to be the sum of time on current and all previous oil tests. The numbers don't make sense as hours and seem high for miles. What are the units and what are the totals on the truck?
No that's not T6. It's looks very much like the Euro L..........Ca is high, Mg is low.So nearing 50k, I finally got around to have a OA done. All oil changes to date have been at the dealer. 1st (4) were from the dealer I bought the truck from, due to an unbeatable package. Last oil change I just did a few weeks ago at a closer dealer, who I asked to pull the sample which they did. So this OA is from 4th interval at original dealer who told me they had switched to the Rotella. Based on the report, it looks like that's not the case, specifically eyeballing the magnesium and calcium numbers - what say you?? Otherwise, pretty happy.
I don't understand the report at all. The comments by Blackstone refer to 8000 miles on the oil yet the results portion of the form says and your note says 4800 on the oil. Your note seems to indicate 6300 on the vehicle but the form says 5497 on the vehicle. The whole story doesn't hang together well. Results look OK to me for a new truck with very few miles on it and the oil. Why don't the various mileage numbers agree? When something this simple doesn't it does not build confidence in the more complex numbers that you cannot check.Just got my first oil analysis back. What do you guys think?
I changed the factory T6 fill for Amsoil DEO 5W40 with Archoil AR9100 at 1500 miles. This oil sample is of the Amsoil with 4800 miles on it. From this point on I will be changing oil once a year with the Amsoil/Archoil (should be about an 8-9,000 mile annual useage). I have little to no experience with these oil reports (this is the first one I've ever done). Any insight you can offer is appreciated.

I'm sorry, but a soot value of <0.1% is simply not believable in these engines. If the oil is opaque black, it has to be over 5%. Which begs the question; is this a GDE tuned engine? How did the oil visibly look when you drained it?Here is my last OA that the dealer did for free with the flash update. Doesn't look like T6. Makes me wonder what they used?
Third was 5W-40 Amsoil Premium Diesel Oil, Second was Shell T6, first was factory fill of 5W-30 I suspect.

I used 5W-40 Amsoil DEO again this time and will run it longer.
This was mostly in-town driving with my new food delivery job. After changing the oil, I immediately trailered a pair of WaveRunners to Miami and the truck sat for a week before trailering them back. I think I will try going the 12,000 as the truck is now at 83,000 miles and with my off-road tune I'm pretty sure any warranty would be toast anyway.Blackstone Laboratories said:BRYAN: Another 10,000 miles have come and gone, and this diesel looks healthy as ever. This report is practically the spitting image of our last look in January, and we're pleased with the consistency. Internal parts are holding up their end of the bargain with no signs of mechanical issues brewing under the hood. You stuck with Rotella T6 this time around, and it's treating your engine well. The viscosity is appropriate for the grade, with no signs of harmful contamination in the sample Try 12,000 miles on the next oil. Keep up the good work!
yes the fuel is high and I do not recall seeing that on any of the many previous samples in this thread. Ref your question it will definitely burn off and relatively quickly when your engine gets up to heat. THe 203 deg F + running temp of the oil vaporizes a lot of the diesel very quickly and with harder use and hotter oil temp it should virtually all disappear. In your normal winter usage that this sample was from what oil temps did you see?My first UOA (ever). Note that my fuel level in the oil is a little high. This round of oil was from this past winter, and I do some idling and short trips. I try to counter that with periodic highway time to get things fully warmed up, but its possibly not working. Once fuel gets in the oil, does it evaporate during a long drive, or does it always remain in the oil? Thanks for looking at my numbers!
