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.


It's vestigial from the 1950s when oil and labor were cheap
and filters were expensive. No good reason now, certainly
not any technical reason. I changed to oil with new filter
every 3K miles in the 1970s.
