Always best to include manufacturer model, year and specific engine, to better serve your questions.0w30 always seems to have better specs on paper but is 5w30 a better oil to run cause of less viscosity additives?
Oil will be ran in direct injection turbo engine and both 0w and 5w are approved. Vehicle is driven all year in Michigan

0w or 5w30What oil grade(s) does your owners manual recommend?
0 or 5w30. I’ve read on here though that others have even bumped up to 0or5w40.What oil grade(s) does your owners manual recommend?
IMO that's too broad of a brush. There's a small difference in the amount of VII between the 30 grades unlike the 0w/5w in 40 grade. In addition the consumer is unlikely to know the type of VII used anyways which is just as important.0w30 always seems to have better specs on paper but is 5w30 a better oil to run cause of less viscosity additives?

@OVERKILL one time posted a blending table and I think the difference in VII between a 0w30 and 5w30 was around 2%.
On an aside a 0w-30 will pump no faster than a 5w-30 once the oil has been ingested by the oil pump. The winter rating is an indicator of effort to turn the crank and gravitational flow into the pickup tube.
You running that turbo, I'd opt for the 0w30. I use 0w and I haven't any turbo.
Does the Owners Manual's oil page / chart specify ILSAC / GF6A..... anything like that?
I ran short oci for first couple changes with valvoline EP and then Quaker state ultimate both because of the higher moly that I thought would help with breakin. Now at about 9500 miles thinkin of goin with Mobil 1 esp and staying with that since it’s easy to find and rated api sp
A few years back it hit -18F in central Indiana a couple nights in a row. But that doesn't make it "normal".It can absolutely hit -22F anywhere in Michigan, FWIW.
I don’t disagree, I just know it’s possible to encounter those repeating and consistent low temps anywhere in Michigan, depending on the severity of the winter.A few years back it hit -18F in central Indiana a couple nights in a row. But that doesn't make it "normal".
My point is valid; there's a big difference between the southern part of MI and the UP. No one "needs" a 0w unless the temps would reasonably reflect a repeating and consistent low temp (-25F ish).
That 2% figure is in terms of the percentage of VII content in the entire formulated oil. A 0W-30 may have around 50% more VII than a 5W-30 (~4% vs 6% VII content).IMO that's too broad of a brush.

The puming viscosity will be lower as well. The thinner oil will have a higher flow rate to the engine when the oil pump is bypassing, and the oil pump on any engine will be bypassing on any cold start in winter conditions.On an aside a 0w-30 will pump no faster than a 5w-30 once the oil has been ingested by the oil pump.

Oh yeah? That's seems pretty much a blanket statement as far as I know.the oil pump on any engine will be bypassing on any cold start in winter conditions.
Remember, Gokhan's estimates were just that, estimates, and there were many oils that clearly didn't function with the estimation function, yielding wildly off-side results.That 2% figure is in terms of the percentage of VII content in the entire formulated oil. A 0W-30 may have around 50% more VII than a 5W-30 (~4% vs 6% VII content).
BITOG member Ghokan published a good spreadsheet that shows VII content and full shear viscosity (HTFS) estimates of various oils. Taking an example, Mobil 1 5W-30 has 4.4% VII and an HTFS of 2.32 cP, while Mobil 1 0W-30 has around 6.9% VII and an HTFS of 2.02 cP. In full shear conditions, the 0W-30 has a viscosity somewhere in between that of a typical 0W-20 and a 5W-20, so it's about a full grade thinner in high shear conditions.
