In a past life I oversaw Fleet Management for a police department. We maintained 100-120 vehicles. Oil was always low bid and bulk. Most vehicles saw 5k intervals. Many of the vehicles ran 24/7 with little down time and thousands of hours of idle time. Vehicles operated in city stop and go driving. Now this is strictly an observation on my behalf and not based on science. We never had any of the used oil analyzed.

We would replace 2-3 engines a year. No engine was replaced due to oil failure. If my memory serves me right, the Ford 4.6 lt engines replaced were because of hydro lock. (Operator Error) Ford Explorer 3.7 engines replaced were due to faulty internal water pumps that contaminated the oil and thus had major failure.(engineering Issues) The Chevy Caprice 6.0 were just pure junk and had engines replaced under warranty. Chevy admitted there were cam shaft issues. (Manufacturing/engineering issues) A Chevy Tahoe 5.3 overheated and had to be replaced.

We used bulk Gulf, Wolf's Head, Shell, Oilzum and Pennwood Oils. Mileage varied from 10k-65k a year per vehicle. I have seen many of these engines with valve covers removed or in various stages of repair. I never saw engine sludge. I only saw clean internal parts with minimum discoloration and varnish.

Based on my experience, I believe any oil API certified would be sufficient for the average passenger vehicle under all conditions. I think a lot of the acrimonious banter on these forums, well is wasted time, although it is entertaining and some of the forums quite informative. As for me, I use quality filters and brand name lubricants that are on sale. I've been maintaining my own vehicles for 40 years and have never had an oil issue. Save your money!

Cheers!

The Caprices were junked as soon and the 100k warrant expired. Many of the Crown Vics/ Explorers are shipped off to auction in the 175k-200k range

The only conclusion I've been able to draw from my time on BITOG is as long as the OCI isn't excessive any synthetic oil within a required spec will do and as you hinted I don't even know if the spec really matters. This makes 98% of what is discussed on BITOG purely mental masturbation with no real world importance other than feeding the OCD needs of the group to obsess over things that do not matter.

thats pretty low miles - I am sure that with extending oil change intervals and fuel economy benefits of using premium synthetic oils....the economics would have sided with premium oils, whether the vehicles lasted longer with them or not. Less downtime too...

All those years on the job and you didn’t save one lousy filter that we could cut open?

The truth is those vehicle are beat like a red-headed step child. Although the engines might still run ok, the body is junk. Many of the cars are stripped of any usable parts and the rest is sent to auction. I've been in Crown Vic taxis with 500k on them.

Mostly regurgitating marketing claims.

Mileage a lot of times isn’t an accurate measure since like he said police cruisers spend much of their time idling. Unless they equip them with an hour meter, of course.
