Hypothetical: Supertech Syn vs Top conventional?

Since Subaru recommends synthetic for my FXT, I'd take the Supertech right now as I'm under warranty.
Probably Supertech no matter what, although I'd probably add some MoS2 to it (PYB has gobs o moly, ST very little if the PQIA results still apply).

The difference between Syn and Conventional is becoming razor thin as well as the difference between (some) store-brand and major brands. I have no-issue going with NAPA or Supertech. The only thing that the major brands have an edge on is the extended-interval oils. It is frog-hairs after that. The brands have better add-packs in some cases, but for most 5,000-10,000 OCI users, the engine will never know the difference (save for the higher-strung performance engines).
Heck, I have been using recycled "prison-oil" for years in my fleet. No oil-related engine failures there.

I'd run Castrol Magnatec at the same price as ST. I use the 5w20 grade.
If not that- the sub $14 Pennzoil conventional.

I would use Magnatec as well but again, this oil is either syn or blend, depending on viscosity. I would use ST over Pennzoil conventional.
I ran Super Tech syn last winter. Abysmal.
Magnetec in the summer and Edge gold bottle.
If I had to pick a conventional for the winter it would be Quaker State Conventional. Best conventional IMHO.

Where is "abysmal" on the above Warren oil chart?

Is Warren the only supplier? No..........
Charts are charts. User experience trumps that.

I wasn't aware that Supertech Syn was supplied by other blenders. It was only Warren Dist. Still, if it was Dexos, not worried about it.
How was it "abysmal"? Bad UOA? What?

You have to understand that the person who posted that has ruined, or nearly ruined every vehicle he's ever discussed on this board. Constant posts about engine damage and truly stupendous problems that no one else ever reports. Also numerous wacky comments about various certified oils resulting in engine damage apparently confined to his vehicles only.
Consider the source.

Abysmal = Extremely noisy operation and poor fuel mileage.
Valvoline "syn" was also poor. Magnetec SS 5w30 in the spring was a godsend of beauty.
Yes, I tell my truth. I don't withhold information to boost my ego.
If I make a poor choice I admit it. If I feel poor performance I report it.
I am not a fan boy.
Fan boys here hate me if I'm not on "their" team.
Discount the above as the typical, juvenile, ad hominem attack.

No attack meant, just an observation. No one else on here claims the huge number of varied disasters and near-disasters like you do.
Not even close.

Well it's a bit more complicated because Super Tech Syn is a USA synthetic and that means what ... It means a bunch of Grp II and whatever ...
But a modern "conventional" means what ... It means Grp II and, guess what, and unknown percentage of Grp III.
So. How do we square the fact that some ppl say Supertech Syn and Conventional are both Grp II with the fact of Supertech Syn's lower Noack/Dexos1 approval?

Because less than a handful of people who post here really have any clue about motor oil. But, at least there is no shortage of guesses offered as fact.

Unless posters supply a link that supports their claim, it's all opinion (some good/bad). The good thing is that we do have many knowledgeable contributors on bitog that do present links to research and articles. In this case, stick with what's listed on the bottles, Dexos is good spec.
