And Warren is actually generous with info about their oils, a link to a 5W30 synth PDS with Noack loss, CCS viscosity, and other juicy tidbits is included below.
I think there's a good chance this would reflect the results for ST 5W30 synth given that the oils have the same d1G2 license # (also shared with amazonbasics 5W30 synth), but I'm sure not offering a guarantee on that.

.... but no mention it reduces deposit formation. None of the Warren-label oils mention it.
Why?..... because it doesn't. Otherwise it would list it on the jug, as Valvoline, Castrol, Mobil-1 and Pennzoil do (5w30)
You get what you pay for and if you're driving TGDIs/GDIs, you may want to rethink your purchase of it.
I found this nice summary of what's "new" in d1G2, which all the oils discussed meet...
"GM has developed four new engine tests for this updated specification:
New General Motors Oxidation &
Deposit Test (GMOD) verifies the improved oxidation and
deposit control characteristics.
New Stochastic Pre-ignition Test verifies the added protection for turbocharged engines and pre-ignition concerns.
New
Turbocharger Deposit Test verifies the added protection for turbocharged engines and
minimizes deposit formation, which ensures optimal performance during engine life.
New Aeration Test (bubble control) ensures the air bubbles in the oil dissipate quickly to improve oil performance."
I'll take the spec over the advertising.
I should probably add here that I haven't purchased any ST oils because I can get "brand name" cheaper with rebates....
