They called back but I missed it so I'm gonna have to try again.

Meanwhile I spent about an hour on the line with Mobil.

The guy who answered wasn't good enough so he patched me thru
to the second level technical support after he pointed me to the datasheets.
http://exxonmobil.com/pds
https://www.exxonmobil.com/en/pds#f:Location=[United%20States]

But the guy didn't know how to answer my questions about motor oil selection
so he transferred me to a second level who transferred me to a supervisor
after a while (which was nice of them as each knew more than the prior).

What I did while I was waiting was pullup a random Costco Mobil 1
https://www.costco.com/mobil-super-s...100594938.html

And pulled up the datasheet
https://www.mobil.com/en/lubricants/...thetic-10w-30/

The 2nd level just gave me more lookup engines for personal vehicles

For example you can put in your year make and model to find their oil
https://www.mobil.com/en/lubricants/...ght-motor-oil/

But it pretty much suggests all their oils (not surprisingly)

If it says Super it's a blend, if it says Mobil 1 it's full.
(Except the exception of Mobil Super Synthetic 10W-30).

If it says "Extended Performance" it's high mileage (20K / 1 year).
If it says "Advanced Fuel Economy" it's not for high mileage.

Basically they only gave me mostly the marketing that was on the outside.
High Mileage & super blends don't meet the dexos spec.
He basically said the full synthetic is better than the blends.
But he said there are no rules anywhere for what constitutes what.

As an aside, he said synthetic oil finds leaks not causes them.
He defended oil detergents as exposing leaks (by cleaning out gunk).

When I asked about filters he said they don't make filters.
He said all Mobile oil filters are rated at 1 year 20k miles.
Mobil contracts out to Mann-Hummel who also makes Wix & Purolator filters.

Mann-Hummel didn't know the answers to the questions so they said they'd
have a support person write to me over email (so I'm waiting for that).

BTW, he said Penzoil starts with natural gas for their synthetics.
