Am I missing something, or are there no Product Data Sheets for Driven Oil, at all? I can narly name of another blender who thinks so little of their customers, or has so much to hide, as to decline to publish such an standard industry document. If true, can we even find a second company who does this??? Even Lucas or Royal Purple publish a PDS.
All I can say is wow, it's great they use "Pennsylvania Grade base oil" (in their 20w-50) from the 19th Century. God forbid someone puts this in their modern Porsche, based on a half-baked recommendation. See my link of Choice-Supportive bias. The 20w-50 page also mentions it's high HT/HS, but then fails to publish the actual numbers. It sure takes faith in the product to ignore these kinds of overlooked data. This product is truly marketed to the unwashed. It makes products like Liqui Moly seem like a technical marvel.
If I'm spending money, I'll at least grab some Ravenol.
Sorry to interrupt the exchange of ideas with another OUA, but this is Liquimoly, HT 5W-40 with Ceratec at about my usual 5k interval. This is the 3rd oil change with this combo. Silicon down to 1. Can't complain with what's working. This combo is about $40 cheaper than DI40 assuming 8 quarts, so I will stick with it.

That one looks good. The Ceratec definitely helps keep the iron down if using LM oil.
Thanks for bringing us back on topic. Wear looks good but I am a little surprised the viscosity is so low; the 11.0 cSt is the viscosity of a SAE 30 grade. What does it mean that they "unmarked" the viscosity of the 12/6/21 sample?
Here is the response from Blackstone: "When we originally sent the report for your 12/6 sample, we had marked the viscosity in bold, since it was below the "normal" range we had established at the time. Since then we've had a chance to analyze more samples from Leichtlauf HT 5W/40, and ended up widening the acceptable range slightly. Since the viscosity in the 12/6 sample fell within the updated range, we removed the bold mark for consistency in your trends. Anytime we change anything in a report we will document it in this way."
Ah, makes sense. Thanks so much for the clarification and for posting your UOA data point. Sounds like the LM HT 5W/40 does run a bit thin in general based on their comment..... your wear still looked good though.
Thought I’d post a response I got from Motul on my questions of why they don’t seem to put any Moly in their A40 approved 8100 Xcess Gen2 5W-40, and if it is advisable to add MoS2 to it separately. It took a while for them to reply, but below is their response. Short answer is that they cannot add anymore Moly because they have to follow the OEM requirements to meet spec, and to not worry about it, as the oil still performs well, and to not add any additives to it. Guess there are other friction modifiers in there that make up for it. What’s interesting to me is that they say there should be about 80ppm of Moly in it where several VOAs on it show none.
“We would like to thank you for your interest in MOTUL and our products. Please, accept our apologies for the late reply.In response to your inquiry, Molybdenum-based friction modifiers are a part of several MOTUL formulations. Because of different raw-material availability issues we are forced to develop and approve with the OEMs different formulations. That is the case with the 8100 X-cess Gen2 5W-40 you are mentioning. This in no way changes the oil performance nor its approval status with the OEM, so you should not worry about it. Chances are you will do another Used Oil Analysis soon on 8100 X-cess Gen2 5W-40 and you will find around 80 ppm of Mo inside.
With regards to mixing the fluid with aftermarket additives, this is a practice we do not recommend, in order to avoid unbalancing the additives of the virgin oil.
We hope the information above was useful to you. If you have any more questions, do not hesitate to write again or give us a call!”

I find this response funny. Don't worry about it not having Moly, but we've added some in the new formulation. Don't add things to the oil, but we make 2 Moly product that are designed to be used exactly that way.

Motul doesn’t make Ceratec and MoS2 (LiquiMoly does). Maybe they use other friction modifiers to replace Moly. I kinda like their oil. It seems to burn significantly less than the M1 5W-50 I was using before and engine feels peppier.

Oh crap, you're right - too early. I actually had good results with Motul 8100 xcess before switching to DT40 which is a little better and for people looking for an A50 approved oil that's the one I recommend to them.

This is a point worth repeating and applies to all oils. The ideal approach is to use an oil that is formulated and ready to go out of the bottle without needing to try to play chemist. Often there are specific techniques required to achieve optimization and are therefore best controlled at the production facility rather than in a garage (for example blending additives at high temperature while mixing to homogenize it).
I see people in the Audi community running the cheapest oil you can buy on sale at Walmart, buying 2 or 3 different oils and mixing them all thinking it's somehow better, etc. Then they wonder why at 100K miles their rings are beat........ clogged with carbon (DFI soot) so badly they don't move any longer and the ring seal is crap; at which time their oil consumption starts to increase exponentially and the motor will eat itself alive
