That post was made by a PR rep. No one with a technical background talks like that.
75,000 miles is such an arbitrary and made up age. If my engine doesn't leak new and it doesn't leak at 75k miles and it doesn't leak at 150k miles, what's the difference?
Yet they recommend using HM oils at 75k miles.
It was quite arbitrary, This was the early to mid 1990's and some in Valvoline thought that 50K was higher mileage whereas others noted that cars were now routinely reaching 100,000 miles on conventional oils when well maintained. The middle ground was 75K...
That's what we were told as they rolled it out in drums at my VIOC...
