Not sure if you guys have heard about zinc and phosporous in oils yet. I’m not going to recommend any brand, but Zn and P levels are important to mechanical wear. There is a GM engine guy that made studying this his life’s work. He has spreadsheets and tables and does standard wear tests on about every motor oil made. Read up. It’s a lot of reading.

Why did Zn and P get lessened or removed from modern oils? Cost and emissions. This was done to the detriment of engine wear especially for slider camshafts. Our engines have slider cams. If you have a hydraulic roller lash adjuster not as much of an issue. They are common in domestic OHV V8s. They are heavy too which is bad for high rpm (everything is a trade off).

If you want oil with enough Zn and P to protect your engine well a certain recommended oil is the easy button. Notice I didn’t say cheap button.

And if you want to dig deeper search lawsuits regarding the label “synthetic” as it pertains to oil. A lawsuit was won that makes it easy to slap
that label on poor quality oil. When synthetic oils first became prominent there wasn’t a standard but quality was high. Since the lawsuit quality dropped. It’s a classic case of if you can’t beat them, join them. So since company Y can call their swill synthetic legally, we will sell swill too because good synthetic oil is now unprofitable. Unprofitable.... so you’re buying synthetic garbage if you are shopping by price.

And again, I’m just some dude from TX, you can do whatever you like. Your money, your car, your engine, you may be Einstein’s daddy, and my advice might be rubbish. Have fun.
