Rounding error?
Well it would be reproducibility, not rounding error. I can't find a "free" copy of ASTM 4741 to find out the value, but for similar ASTM methods it is somewhere around 3-4%. It may be different for ASTM 4741 since this is the new and improved method of determining HTHS.
Don't worry yourself with that, he was just looking at the wrong P66 product, the 5w-30 is rebottled Shield Valor not Shield Armor.
I wasn't looking at the "wrong" P66 product, I was looking at a "different" P66 product.
At the time of my post, you hadn't referenced P66 Shield Valor (or the previous BITIG thread).
At any rate, it does appear that some Redline products are repackaged P66 products. Disappointing.
No hostilities from my keyboard,

I had linked to the previous thread in a prior post that you must have overlooked. And yes, you were looking at the wrong product in the sense that it wasn't the one that was the match for the product in question, that's all. No hostilities here either, I had delved into this quite a bit back when the thread i referenced was current, which is why I had made the statements I did.
