And?

So a 16-grade or a 20-grade won’t violate the warranty but a 30-grade (or above) will? I was just going off the word “safe”.

Since you seemed pretty interested in ESP in your other posts about oil selection, why not use that? Go by the approvals the oil holds, not by marketing blurbs. EP isn't "special" except that it is for long drain intervals. Is that what you plan?

Depending on the starting temperature you can safely use anything from a 0W-8 to a 20W-50 or 10W-60.

Which for approvals and licenses at least, are parameters based on actual quality tests rather than focusing on one isolated property or reading the tea leaves of a PDS or SDS.

Really only if you’re attempting to fine tune it to some mythical sweet spot. Pick something with more than adequate HT/HS and keep an eye on fuel dilution.

This is so crucial.

I don't know exactly, but here is one answer from someone who knows more than I do: https://bobistheoilguy.com/forums/threads/flash-point-and-noack.284395/#post-4676373

Does it mean that? And in regards to pour point, that doesn’t always accurately represent the pumpability of the oil at low temperatures. We’ve seen several examples of oils on here which have low published pour points that don’t result in a superior winter rating.

Sure why not. A good price too.

Why is this not in Humor? You’re acknowledging what everyone else already knows.

But flashpoint testing IRT fuel dilution is supposed to be strictly a screening test not a baseline determination. My biggest beef with those labs that use it as reportable values on a UOA.

Yeah I used to perform flash point tests, with automated equipment it is more repeatable but the repeatability and reproducabilty is still not good for the test. No standardized test uses it for some general quality parameter. If someone wants to gauge the quality of a Group III base, that...

Cope how? With igniting? What are you attempting to achieve? Use flash point as a proxy for oil quality? IMO it is one of the least important properties listed on an SDS, and is there for fire fighters and first responders. It's also one of the least precise tests.
