Flash Point HIGHER than Fire Point?

Just wondering if this is something explainable, maybe I have missed something during my time on BITOG. If the oil catches on fire before it evaporates is that a good thing? Is it possible? A typo? If it was a typo it seems that it would have been corrected. If you notice some of the other Mag 1 lubes follow this pattern. http://www.wd-wpp.com/specsheet/motoroil.pdf PS: Sorry for Posting and deleting as I was confused.

Either mixed up numbers or inherent variation in test results. The numbers are very close so it wouldn't take much variation to reverse the usual trend.

Lack of great repeatability plagues those two tests. Tom NJ has said what it can be. IIRC, 5 or 10 degrees F are not significant differences.

What issues? As far as I can see in that document, all other grades have fire point which is higher than the flash point, and that's OK, IMO. Only the 5w-30 grade is out of whack.
