I see too often that employees at Autozone, PB, O Reilly's, etc recommend oil grades ( 5W30, 10W30, 10W40, etc) depending on mileage. They think the older the vehicle the thicker the oil the vehicle needs. I saw someone recommend a 20W50 for a vehicle calling 5W20 one time. Has anyone else came across this?

Another I hear is, "I change my oil all the time." in response to a high mileage oil or synthetic. What does that have to do with it?

The last mechanic who changed my oil told me that Pennzoil Ultra was no good. I tld him it was one of the best and he looked at me like I had flaming bananas protruding from my ears. I told him about the Ferrari connection and he honestly thought I was [censored]'ing him. After he was done I showed him the site on my smartphone and he was dumbfounded/embarassed.
This is what they typically say
0 miles to 75k miles = 5w30
75k to 150k miles = 10W30
150k miles to 200 k miels = 10W40
200k miles + =20W50
0 miles to 75k miles = 5w30
75k to 150k miles = 10W30
150k miles to 200 k miels = 10W40
200k miles + =20W50

Not all "Parts Jockeys" are bad or ignorant. There are professional Parts Specialist that take pride in their jobs and are highly qualified, we are just hard to find.

Some engines that are a little sloppy do very well on 20W-50. I used to have a 7.0L in a Cadillac and it ran the smoothest and quietest with Exxon 20W-50. It would burn rubber for 30ft. before it finally hooked up to the asphalt. That's with tall 2:73 highway gears too. It didn't like to pass smog though ... the state finally made me get rid of it. I miss that car dearly.
Only in California
I wish our emissions test weren't so strict...
It was a 1978 Sedan DeVille. If you were to put the car up on a lift and take a look up underneath it, you'd swear
you were looking at a full size pickup truck. It even takes the exact same size tires as a 1997 Chevy Tahoe.

Agreed. We need to clone the good ones then! I have not found goods around me.

+1 some well versed guys would be great! Or even better, well versed cute ladies!! Now that would boost sales AND get you good advice!
Seriously, I had 3 in an AA look at me like I was asking for a specialty part when I sought a tube of friction modifyer. They said they didnt carry it. A few munites later, by the differential fluid shelf, what do ya think they had??????? Yup! Friction modifyer.

Frankly I'm unaware of any Cadillac from the 70's requiring anything other than a 15" wheel & tire...
Probably an L78-15 bias ply or 235/75-R15?
Maybe on a Limo, but I doubt it.
Cheers!
p.s. This was also a common size on an F150SC: 235/75-R15XL
I thought GM had gone to 16" on just about everything by mid-90's...

The main problem , is training. There is a serious lack of training in the industry , I hate to say it but maybe 1 out of 10 "parts specialist" should be behind the counter. Try to find a Counterman with ASE certification , hard to find but we exist.

Next door neighbors at the time had a '97 Tahoe with stock wheels and yes,
the tires were 235/75R-15. They might've even bolted right on the Cadillac.

To the typical non-BITOG or otherwise non-car person, those numbers at least sound plausible. I could see how someone could be convinced to put 20w50 in their 200k Honda by a counter person. In reality, they're just shooting from the hip.
