It's vestigial from the 1950s when oil and labor were cheap and filters

changed to oil with new filter every 3K miles in the 1970s.

I already explained in great detail that it's not at all about money.
It's about design and function.

Most people want a simple answer to everything which money is to them.
But not everything is a simple dollars to dollars decision like you
claimed.

If all you care about is money then knowing that both the oil filter and
the
oil are cheap you're welcome to throw away both at the same interval which
is why I said it's up to you.

But stop saying it's about money when that's only how YOU think.
The manufacturers think differently than you think.

For them it's about engineering.

Many manufacturers recommend oil filter intervals different than oil.

If you disagree with the manufacturer then you should answer this
question:
Does the oil filter always fail at the exact same rate as does the oil?

Its not fail, its about how they age.

They fail with age, auto-contradicting senile asshole!
