    I pulled an oil sample when I changed my engine and filter at 500. I finally got around to sending it out.

    It's the very first sample the lab has performed on the Hellcat 6.2L so they have no unit averages for this motor.

    Iron and copper were high... The iron is break in wear (cylinders and any steel on steel wear), the copper is bearings, bushings and copper is often used in the coolers so it could be coming from the oil cooler. I was expecting more silicon from gasket material but maybe they aren't using much RTV in this motor for sealing.

    There was a trace amount of fuel which doesn't surprise me. This motor seems to run on the rich side and there were some cold starts without a lot of run time (I got the car in February and really didn't drive it until the end of March but there were several cold starts without a lot of run time).

    Viscosity was just slightly out of range on the low side. I"m assuming that the factory fill was Pennzoil 0W40 but really no way for me to know for sure. The trace fuel could also lower the viscosity a bit.

    Nothing here that concerns me for a brand new motor but it will be interesting to see how my motor trends and also interesting to see the averages as they sample other Hellcat motors.

    Glad I changed it at 500 miles.

    What did the analysis cost?

    It's $25 for the report I posted. Another $10 to run the TBN. Unless you are doing extended oil changes no need to do the TBN. If you are running 5 or 6K oil changes I would do the TBN a couple of times just to make sure the oil you are using is up to the task.

    I am going to change mine next week end. I guess I'll get analysis done. I'll be putting Amsoil 0w-40 in her and a magnetic drain plug. Is this the filter being used MO-041? Any info...Thanks

    I used the 041 filter on my car.

    Fuel dilution will contribute to viscosity reduction but I've seen this oil read there fresh.

    Your potassium levels are a smidge up watch that it can be a sign of coolant entering the combustion chamber.

    Sodium is also up slightly which could be related to the air filters performance.

    I run tbn and tan together they will tell you when to change the oil, n/a with 500 miles you have tons of additives left (as expexted) that combat acidity from blow by by products.

    Having said all that with no history agree all looks ok, especially with so little run time.

    It would be nice to see others getting analysis with Blackstone. We can watch the averages grow and see trends both on our person vehicles and as a group.

    Site says $25 per for the basic that I had but they actually charged me $22.50. I'm not sure why the difference but no big deal either way. Looks like $22.50 and $32.50 with TBN

    For reference here is a VOA (Virgin Oil Analysis -- unused sample) of Pennzoil Platinum Ultra 0W40. Figured it would be handy in this thread. Grabbed it from another post on this site.

    What I want to see is data from a car driven hard displaying soot out of exhaust with 1k+ miles on the oil. Not because of car concerns I want to see how the handles blow by (acidity, oxidation and viscosity impacts) then same with Amsoil, then other brands.

    Trucker Bob I'd love to see an analysis of the Amsoi 0W40 when it's time to change that out. I bet it is a great oil with a solid additive package.

    I
    I will post. I think I might save the money on the first change....Any thought?? I also wonder how the magnetic drain plug will affect the second oil change?? I plan doing the second before road trip to DuQuoin at the end of June.

    Entirely a person decision. I was more interested in catching any big problems early. Things like leaky head gaskets or crazy wear indicating a bigger problem. For me the analysis gives me peace of mind that my motor is running well.

    Is this necessary... Of course not.

    From what I've seen with other vehicles and the analysis, AMSOIL is fantastic...holds up extremely well. Depending how large this thread gets I will predict that PUP and AMSOIL will dominate in regards to the best results/performance of a motor oil.

    Great resource thread. I love these types of threads. Thanks for sharing this info!

    I would expect the same results. I will post the second change
