What Oil Viscosity for Southern California Car?

The truth is that all oil brands are good when used as intended. You literally can't go wrong with the oil sale of the month at Walmart. If we could put 200k miles on engines in the 60's with crap oil, just imagine how much better off those engines would have been with today's oil. We didn't have synthetic back then.
 
See how much garbage is in my garbage engine, lol.


Send it out for a SOAP (Spectral Oil Analysis Program).


This one is one that I found that's pretty near you.

While I mostly agree with the first two sentences. I do take issue with the 200k in the 60's, I lived and worked around my family's gas station and the body shop, drove tow trucks so I was there, a truck with 130k was a rolling smoke show and most cars were 'out to pasture' at that mileage too.
This included 'fleet' vehicles.
Now a diesel OTR truck will get 200 even 300k on them before rebuild.
My experience, others may differ but not by much.

While I agree that it's not always the case, it did happen.
I remember 3 vehicles in particular. One was a Ford Galaxie with a 352 V8.
The other 2 were Mopars. We had a Dodge truck with a Poly 318 that hit 200k miles before rusting out. The other was a '69 Polara with a 318. It had just over 200k before being totalled.

In '71 we bought a new Dodge Power Wagon 4x4 for the farm. It had a 360 that served us well into the mid 80's. Our neighbor gave us crap about owning that Dodge as he was a Chevy man. My father told him when that truck hit 200,k, he would drive circles around the neighbor's house. Well guess what? Old Earl had a circle track in his grass from that truck. Lol. When the bed rotted out, we parked that truck. We used Wolfs Head oil out of a 55 gallon drum for the tractors and vehicles. They all used straight 30 if I remember correctly.

Maintenance goes a long way.

I agree and I've always, until recently, used Wolfs Head, I liked the green color, it's Amoli or Amsoil owned now, kinda like Wix filters, industrial grade stuff.
the old crude oil you're great great granddad used had a lot of paraffin (wax) as an ingredient and was used in cheap oils up into the 2000s maybe even still today.
Examples Brand X 8200 miles (53 chevy 3100 6cyl) will use any basic 30w cheap crap mostly because it has no oil filter, yeah that's right it was an option in 53! So it gets changed often, I also installed a PCV system so no draft tube, google the engine draft tube, real caveman stuff compared to today.
The Dump Truck, 97 SD Power Stroke, 600k+ miles, no engine work EVER! Wolf's Head synthetic blend truck oil, not even a valve cover removed.
Oil is important more so today because of technology, hell I bet I could run vegetable oil in Brand X
 
I'm very familiar with road draft tubes. Remember toilet paper oil filters?
