Did oil analysis on my pickup with this oil and was told to change it at 2500 miles or upgrade to truck and suv version. Viscosity breakdown

Quote from Arcticat

I was using the best Castrol 505 & 507 oils in my Audis, even the new bottles had a dark slime at the bottom. I shake the bottle to mix it, not so hard that I aerate the oil and then used it. Never had a problem. I get that they might not be as good as new but they are not going in the garbage or the recycler. I'm not talking about oils that look as dark, or smell like the ones in the video. It's good to know some of the info like the foam disappearing, maybe just use them in a 50/50 ration with new oil, or use an aftermarket product to restore the additive package. The older Mag1 oil bottles (that I still have and look the same as when they were new), were clear and they had a dark slime at the bottom even when brand new, I would suspect that if all the bottles were clear you would see some kind of sediment there. Some of the oils being sold, especially online could be 5 years old or older already. So if I bought oil in 2020, especially if it was in stock or on the shelf for a while, I should just get rid of it? Not happening for me...

We both have some of the hardest oil specs to find on the shelves in stores. I have a 15 Audi Q7 TDI with 107k now that calls for the VW 504/507.
The last oil change in January @8,000 miles on M1 ESP Euro 5w30; I decided to send in a sample to SPEEDiagnostix [speediagnostix.com] for analysis. It was so surprising bad that Lake Speed Jr himself called me directly to discuss the report and derive a plan going forward.

The quote from the report states: "Viscosity and Oxidation are both elevated, which indicates the additive package has been depleted " And that was from a fresh 5qt bottle (purchased at WM) with no noticeable residue at the bottom when emptied (meaning no additive separation from sitting too long on the shelf or dropping below freezing while in storage).

We decided to continue with the M1 ESP one more time as a control study but, this time try retesting @4,000 to see how it is doing. To take the study a step further I took it upon myself to send in another sample on the fresh oil change, with only 100 miles of driving to let it mix with the residual in the crankcase, to get a baseline to compare to for next 4k.
Regardless of the results, I will never be going over a 5k oil change interval again. [That factory VW/AUDI 10,000 OCI is BUNK!!!] And I am probable going to give Valvoline's Euro FS 5w30 XL-III [valvolineglobal.com] a try next.

Hey everyone, just want to say I appreciate the conversations! Applause

My goal here is to make this thread more educational than usual and not just about saving $'s on the oil you buy but, maybe bigger $$$'s in savings over time. I want to encourage you to go back through it and see some of the other links and info shared. nod

I have been following Lake Speed Jr (The Motor Oil Geek [youtube.com]) for some real scientific data to reference. His information is coming as a Lubrication Specialist (Tribologist). worship

His channel is far more valuable and understandable than other motor oil sites and forums that are just mostly full of confusing subjective opinion more than science. Confused
