What is the best synthetic oil?

WarmAndSCSI

It's only junk because it's overpriced and even a lesser oil than several cheaper off-the-shelf oils.

Any oil marketed to increase horsepower output is falls under the category of snake oil BS. I have nothing more to say on that

Royal Purple is junk, not because the oil sucks, but because the marketing and pricing does. Kind of like AMSOIL...

It's not worth my time to post up evidence of bearing wear over a few years of tearing down and building engines. Too much to present, and I doubt anybody except one who possesses actual tuning and engine-building skills would be able to reasonably interpret such evidence.

Here is a one-line summary of what I found: all oils marketed as synthetic protect equally well, essentially. However, I have found some oils such as Mobil 1 0W-40 and Red Line 10W-40 to provide enough protection to actually prevent and mitigate engine failures.

Anecdotal engine building wear analysis means everything to people who actually build engines. Probably doesn't mean much to somebody who pays a shop to install bolt-ons

Talk is cheap so lets see this so called data. Doubt you got it and doubt you have a mech. engineering & physics degree to really understand what you would be looking at.

OK chump. Let's recap how you started this argument:

Doesn't seem like something who has a would even utter. Seems like something a fanboy would rattle off. Why don't you present some hard evidence showing Royal Purple is better than everything else? As an engineer (whooptefucking do), you should know that the burden of proof lies on your end if you're claiming a single product is better than all else.

My only statement was that RP is overpriced, mis-marketed garbage. And it is. The oil is good, but definitely no better than any other Group IV or V-based synthetic.

I'll let my actual tuning, mechanical, and engine-building experience speak for itself. Seems a lot more relevant than having a piece of paper that supposedly states you have a conceptual understanding of such things. Experience > Degree.
