0w or 5w-30 with HTHS of 3.5 HTHS or higher

Sorry, just to clarify, which has better base oils? What are the bases for SS and Euro?
SS more expensive because more but lighter ester, which is more expensive than PAO.
It's (I would say required) for passenger cars (SUV, pickup trucks) with turbo gasoline and diesel engines.
What's the base oil composition for XL and HM?
Group 3 with small amounts of 4 and 5
And just a different add pack between XL and HM?
Slight difference in base oil too.
FTR I don't know formulations. No one posts exact formulations here as you know.

There's almost no reason to run a 5w-30 or 0w-30 on viscometrics alone with the Euro 0w-40s have nearly identical hot viscometrics while allowing better additives for essentially the same cost.
The 0w-40 Euros will come in HTHS of 3.7-3.8 BARELY higher than the 30 grade. KV100 they are also barely higher. Cold flow will be nearly identical too.
The advantage of the 40 grades is that it's much easier to find a stouter full-saps additive package. The majority of 30 grade euro oils now are mid-SAPS at best, with some pushing to low.
True that - it's the difference b/w A3/B4 and C2/C3. However, you can still find 5W30 A3/B4, for example Castrol.
A guy just found it in Walmart for his generator, in the Lawn Equipment forum.

Can 0W-40 be used in a direct injection, turbo motor? 5W-30 has the Dexos1, gen 3 spec but I don't see it on any 0W-40 bottles around here.
I have used it in mine, it works just as well as a 30-grade.
Curious, why do you think it couldn’t be used?
Yes some Walmarts near me still have it.
Can you describe the utility of assessing SAPS level and its relation to additive package? I know that lower SAPS oils are important for DPFs and other emissions concerns for European vehicles. But if you just have a standard cat found in North America, how do lets SAPs impact your oil choice?
Another question, with regards to 0W-40 oils, how does the Quaker State Euro 5W-40 compare to those?
Is the HM "new" or get a formulation change recently? I just saw it described as "new high mileage" Amsoil.
They describe far fewer deposits but with a different test (not sequence IIIH): https://www.amsoil.com/p/amsoil-5w-30-100-synthetic-high-mileage-motor-oil-hm530/
It's a relative new oil from Amsoil. For years and years Amsoil said they would not make a HM oil. Wish I had a grubby engine to test it in.
I've got just the candidate. 21 year old truck run on dino. I'll be the guinea pig. Hit me up.
Split the cost of a case at my wholesale price, drop shipped to you "out west"?
I'm down. I'll go in on a UOA together too and post results if you're keen. I've got a filter cutter too, and I'm happy to post filter pics.
It is definitely not a "need", it's more like a want.
