So what do you guys think is so special about your oils? I never know what to buy because everyone claims their's is best anyway. I've been using Pennzoil 10w30 or Castrol GTX 10w30. I used to run 15w40 Rotella. And I've used 10w40 Royal Purple, still have half a case in the shop. I can get Mobil 1 10w30 easy enough and thought I'd try that. Never had a problem with any of them.
Pennzoil 10w30 is in my car now though.
Don.
People prefer “special” oils because of what’s formulated into them.
Nothing wrong with Pennzoil 10w30, Castrol GTX 10w30 or Mobil 1 10w30, but they are API (SM) rated oils. SM rated oils are required to have lower zinc and phosphorus levels which is not a problem in newer cars.
If you’re running a older modified V8 with a high performance flat-tappet camshaft, you need motor oil with higher levels of zinc and phosphorus.
Do a search here of the board for zinc and phosphorus (ZDDP).

I've found that the filter is more important than the oil. The zinc thing is something to consider these days but head to head, oil is oil. I'm talking a given 10W-40 versus another 10W-40, etc. Not a syn oil against a dino, or any other combinations like that.
I want my fair share

You are right that motor oil filtration is an important factor.
The Society of Automotive Engineers (SAE) has known this for a while now.
See also: SAE Oil Filter Testing and Correlation Between Engine Wear.pdf - link
As for motor oil, if we are talking about comparing a non-race off-the-shelf name brand API rated petroleum 10W-40 to another 10W-40, probably not much difference there.
However, motor oil formulators have a vast menu of base oils and additives to consider when formulating a motor oil product. This goes for both conventional petroleum oils as well as synthetic oils. Based on a price to performance ratio, formulators can use inexpensive ingredients or high dollar ingredients to meet their objectives.
This is why some motor oils cost more than others; because motor oil is not created equal.
Retired VP of Marketing at the Hatco Corporation, Tom Schaefer, can explain this better than I can.
Excerpt from fom Schaefer’s article, What’s In Your Oil: Choosing the right components of the right chemistry in the right dosages is a real balancing act, as each of the components have their own pluses and minuses and can interact or compete with each other. Don’t try this at home - leave it to companies you trust who have the technology, R&D, and resources to achieve the necessary balance so critical to performance.

Look at the phosphorus and zinc content in the lab test I posted above and compare it to the other brands.
