75,000 is not really an arbitrary number.
They chose the midpoint of the design life.
Design life of an automobile is 150,000 mi.
It's been the industry standard for years. They design for 150,000 mi service life. I think that's the B10 Life (90% without major repair). Obviously sometimes they fail. Like Honda with the 98-2002 B7XA Automatics. Cars with them definitely exceeded a 10% failure rate. Given the complexity of the job parts have to be overengineered to avoid all the compounding of the odds catching up with you early. Some cars get lucky and survive ridiculous mileage and some don't. This explains though why lubed for lifetime sealed trans and non-serviceable drivelines (integrated ujoints) have become a thing.Which manufacturer publishes those numbers ?

I'm sure glad no one told me or any of my cars that.It's been the industry standard for years. They design for 150,000 mi service life.
Yes we routinely have cars last beyond their designed lifespan. I'm just saying they didn't pick 75,000 out of the ether. It's half the B10 (90% of vehicles without a major repair). Now the new 150,000 HM we can argue about whether they simply doubled the regular HM or based it on being on "borrowed time".I'm sure glad no one told me or any of my cars that.
That guy purchased High Mileage oil because his new car got over 40 MPG.
What's the baggage of GF6?5w30 high mileage oils are going to come with the baggage of gf6.
in your case it will be an obvious step down
No they didn't. Valvoline invented "high mileage" motor oil and they had an internal marketing debate on whether they should label "high mileage" on the bottle as 50,000 miles, or 100,000 miles. They compromised in the middle at 75,000. That mileage figure is 100% arbitrary marketing jargon.75,000 is not really an arbitrary number.

Pennzoil doesn't think you should. This guy's podcast series is on Pennzoil.com so it would seem to be corporate policy.
