I have found some of the answer, but I think I also found a mistype.

Here is a quote taken from a thread on BITOG about low NOACK for Pennzoil Ultra 5W-20 SN

Quote:
This was their reply to my email asking about the noack and test.

Dear Colin,

Based on the data, yes, they are correct. As for the Noack test, it
is done at ASTD D5800 at 250C.

Regards,
Technical Service, sn
250*C is 482*F, beyond the flash and fire point of the lubricant. It would burn, no way they are testing NOACK at that temperature. Most likely, they are testing at 250*F. In that case, Amsoil tests at 302*C (150*C).

More tests comparing apples to oranges.

In the past six months, I have been told by those at Amsoil corporate that a new GTL (Gas To Liquid) process was about to be the new best base stock for a formulation. Let's wait and see who else jumps on the bandwagon with their best formulations.
