Here's a couple UOAs of RK dino oil at 10k miles. And it is contrasted to the other two UOAs of Peak full synthetic.
RK dino oil at $1.59/qrt is the unsung hero of the lube world. Does everything you could ever ask of it in a typical use scenario, and does it well, and does it for cheap. Pretty much no engine "needs" a syn costing $4, $6, $8? What the owner wants and what the engine needs are often to very different things.

In the UOAs, samples A and C are on a 2005 MGM now with over 240k miles on it. Samples B and D are on a 2007 MGM now with over 100k miles on it.
When I first posted the UOAs, I left out the descriptions (oil brand, base, grade, etc) so folks would focus on the results of wear and contamination, not some brand or grade or base stock. I have updated (edited) the post to include those now.
As you can see, RK dino oil is good stuff, and performs on par with a brand name syn (Peak). But that's pretty much true of most all lubes; any decent API licensed product used in the correct application will do the job well. Too many folks are hung up on brand/grade/base and frankly, it just doesn't matter. You're much better off being loyal to your wallet than some brand.
