It's all manufactured in the same factory by the same people under the same quality control standards. They have different engineers designing it, and they have different use cases.
As is the case for TGMO. It's produced by Mobil, in the Mobil facility, to Mobil's quality control standards, but formulated for Toyota, to Toyota's specifications, and sold through Toyota dealerships. It's the exact same situation as what we are discussing here. That doesn't make TGMO part of the Mobil product portfolio/product line.
This is the same for any OEM, because none of them blend their own oil, be it AC Delco, Motorcraft, Honda...etc.
You're looking for issues where there are none. It's HPL oil, different product families. Again, it's something to note and be aware of, anything beyond that is just drama for the sake of drama.
The fact that it's mentioned so often on this forum is not indicative that the product lines are confusing, it's more indicative of how obsessed some people on here are about minor differences and looking for issues where there are none.
You really struggle with being wrong eh? LOL
Let's say next year Dave decided he was just too busy to continue to blend the HPL red label product for HPL Advanced Lubricants (HPL/HPT) and they had to switch to another blender, what would happen? Well:
- The product wouldn't change. It would still be "HPL" from HPL Advanced Lubricants, blended using the same formula as specified by them.
- It would still be sold through the same distribution system, likely in the same bottles and boxes.
Do you see how this makes your claim that "it's HPL oil" problematic?
Circling back to TGMO once again, TGMO sold in Japan isn't blended by XOM, but both it and the XOM blended product are still TGMO. If Toyota moved production to Shell tomorrow, that doesn't make the product part of the Shell product portfolio, it remains TGMO.
Just like we don't consider the iPhone a Foxconn product, even though they manufacture it. Apple could change manufacture to LG or Samsung tomorrow, the product is still an iPhone.
