Exactly. It's all in context. What if it turns out that an oil company is paying that guy? "Oil is cheap, engines aren't". Ok then, change your oil early. How about every 500 miles? What? Is that TOO early? But everyone said changing earlier will extend the life! Why is 1K ok but 500 is not? That's just the engineer in me, if you want to vary from the specs, sure, but back it up with data. That video of a backyard mechanic on Youtube did nothing to prove it helps. It's no different than asking a forum "What's the best p/u ever made?". Impossible to "prove" any answer to that question.
What I find interesting is that no oil company, no automotive engineer, or even professional engine builders ever recommend doing it earlier than what a manufacturer says. I've heard fleet managers use the lab results to set OCI to minimize maint and it's often higher mileage than recommended. And after driving 6 different vehicles in my life well over 150K, a couple over 250K, I agree. I change it when it needs changed. But again, that's just an opinion.
That's your story. That's the beauty of all of this, we all have our own story that shapes and tweaks our experiences and outlook on things. Out of the many trucks I've owned I've had what I would call two failures. Both Dodge RAMs. One needed a transmission at 60ishk and one needed a transfer case before 100k, then developed a similar transmission issue. Maintenance was perfect on both of them. This has obviously shaped my outlook on RAM trucks.
Nobody, besides the engineers at GM, knows exactly why GM had lifter issues. Lots of guesses and assumptions but nobody has the answer. If someone thinks that an early oil change helps, great, have it it. Because of this engineering fail several "fixes have been theorized" Early and often oil changes, keep it completely topped off at all time, disable the DFM, and on and on and on.
The same goes for Toyota, Ford ... you name it. Very rarely do we as consumers actually get to know exactly why.
So, you can engineer the shit out of some things but in the end the human experience is different for everyone. The unexpected happens.
One last example. Tim did a video of a guy modding the rear diff breather tube and it was labeled a fail or whatver he called it. Here's the problem, Toyota had the exact same "problem" on their 2nd gen Tacoma. So, a common mod was the moving the rear diff breather tube higher up. Toyota engineers said the exact same thing, it's not needed. Our filter doesn't pass bulk water, only vapor. The problem is there are literally dozens of videos of 2nd gen Tacomas changing the fluid out after a day of off-roading and fording some water where water had very clearly flooded the rear diff. Chocolate milk. They changed the fluid before they went out. Something unintended and untested was happening and putting the diff breather tube higher ont he truck solved the problem.
My grandfather worked on vehicles as a certified mechanic in the military and for over 35 years after. He told me to change the engine oil early so I do. He also regularly told us to use the brakes to slow yourself down, not the drivetrain or transmission, why? Brakes are cheaper than transmissions.
In the end, nobody really knows, so do what you will.
