Once it gets in the bottle it is the same as far as API is concerned.

I agree with you that oil is a commodity which people obsess about.
Mostly because advertisers want to give people something to obsess about.

Every brand is different but those differences won't matter much to us.

What matters mostly is how often we change it (IMHO).
Which itself matters mostly based on our weather & driving patterns
(IMHO).

And even that is subject to a lot of personal opinion (IMHO).
Everyone makes their own assessment of what to use & when to change
(IMHO).

(My personal opinion is twice a year for dino & once a year for synth).
(My personal opinion is a filter change roughly about once a year.)

I'm curious. If you're going to go to the trouble of changing the oil
twice
a year, why not change the filter twice a year, as in, doing both at the
same time? It seems like only a small increment of extra work and expense.

When my old Chevelle was blowing a quart of oil every 1000 miles or
so, the filter was all I changed.

My VW Golf/Rabbit didn't use that much and it wasn't
blowing it and I didn't even bother to change the filter
because the oil didn't get all that dirty before it got used.
