Machinery needs maintenance. So, if the plans are to will the vehicle to great grandchildren, then some initial maintenance is smart.
And, as always, not everyone has the same commute, or vehicle reputation, or driving pattern, or weather conditions.
...
Its not paranoia to maintain machinery. Its foolish to think that what you do will work for everyone. And, if they don't do what you do, then they are antienvironment, wasteful, and paranoid.
...
If you keep a vehicle long enough, plan on maintaining it. If you lease, trade in too often, or destroy vehicles, is there a point to maintenance? Minimal is fine for a bubblegum ownership pattern.

If he said, "I changed the oil once at thee 2000 mile mark before the 5k oil change" that would be reasonable.
Three oil changes before the 5k interval is excessive anyway you look at it. 4 refreshed sumps in 5K miles is NEVER necessary
NO one is saying NOT to maintain you vehicle.
I retired last year and now I drive 6K a year vs. 15K,
I'm trying to figure out if I should do Spring and Fall seasonal oil changes or just Fall oil changes.
I'm thinking the Former - since I have a lot of short commutes and Idling where I had NONE of that before.
But I sure ain't changing every 1.5K miles - that is for sure.
