What does this mean in practical terms?.... not much. But then we're an oil web site; such esoterica are discussed.

Exactly (they're going to "cya").. and lol at the last part. There's the law of unintended consequences...a chance mixing formulas could throw off the balance of additives. From a practical standpoint, how much of a concern this should be is beyond my pay grade.

real blenders will tell you that when you blend 5W30 and 0W30, you get 2.5W30
Everyone happy now?

my point is there has been many threads recommending against mixing ... regarding the performance specifically the cold (very cold) temperature performance and the issues that it may cause.
I think the conclusion was that if you have to mix once in a while to get rid of leftover oil, it's ok but don't make a habit of it.

basically, I wouldn't do it in winter if I lived in Alaska or N. Canada. Not worth taking the risk.

No kidding. If you read the Q&A on the listing, somebody complained about the 'before discount' price being $10/quart. Based on the response, I'm guessing that they've since updated it to remove a hypothetical shipping charge and they're posting the lower price. Either way, they're putting the buyer over the barrel, so to speak.

I would assume it would be 10w30.

It's wasteful to use Schaeffer's if you're going to just dilute out that antimony additive!!

I mix m1 0w16 with pz 20w50 in a 50 50 ratio. Smooth like butter. No harmful effects. This is my summer brew. Cheers.

There won't be any "harmful effects" if they are API licensed oils, that should not be the focus of the discussion. Successfully passing ASTM D6922 demonstrates there will not be harmful effects.

But the mixture you made may not necessarily meet any specification, license or approval including SN (and likely does not).
