Interesting, thanks for doing this and posting it!
Nicely done. Controlled the variables as much as possible for a good comparison. As you likely know Kirkland=Super Tech Syn 10k = Amazon Basics. Good oil and your specific10k mi. oci explanation makes sense. Not for all, but works in your case.
Another comprehensive vid. Appreciate your honesty regarding why the long interval works fine in your particular situation and the breakdown of the Blackstone data. I think they should breakdown their data regarding what makes up the additive package etc. as you did for us 👍🏽
Good Job on testing at 5-10K intervals, I will still continue to change at 50-60% on oil Monitor between 4500-6000K miles with Kirkland oil with BG MOA Additive even though I could go longer, this oil is economical and 2 times a year is good enough for me on 4 vehicles
Have you the seen the video from Automotive Press on "How often should you change your engine oil" with the chief Nissan GTR engineer? Or "Engine Oil Frequency: Engineer explains how often to change your oil and filter"?
In your unique highway driving situation, it can work for you to do longer OCIs.
Perhaps Blackstone might want to expand and further clarify (or tighten the criteria) in the "Insolubles" section in their data charts. Because, although the oil can still work and function decently, the Nissan Engineer notices other anamolies after taking apart hundreds of engines at very specific mileage intervals. Blackstone is just another business. Not the Delphi Oracle. 😉
Maintenance is key. 🔑 Clean oil is the best oil.
Great videos.👍 Keep up the good work! 😊
Missing the TAN crucial for these results total acid number, they state the oxidation but not input on the sheet.?
Interesting on those numbers being higher for the additives & an odd email response for 10k, I'd find them unreliable; might just be a simple scam to extract money🤔
Does changing the oil at 5 or 10k miles cause more carbon buildup in the engine?
odd results decreasing additives then increasing. I wonder how accurate the test is … ie … what if you sent in 3 samples of the same oil at 5000k? Theoretically they should all be almost identical, but what if they are not?? Maybe the sample from the bottom of the oil pan (as soon as you crack the drain plug) is different than the oil from the top, and totally different if you took a sample after stirring all the drained oil?
He does say he adds a little bit more oil each time he takes some out
