Why is 0w20 Pennzoil Platinum's Flash Point Relatively Low?

Personally I prefer to compare Flashoint after a run of 7.5 k miles then you can make your oun assesment .There is a differance between D92 -D93 .

I believe that the flashpoint of PP went South when PZ reformulated to meet Dexos1 Gen2. PP D1G2 5W30 flashpoint is 207C while PUP (non-D1G2) 5W30 is 224C, both using ASTM D93 test procedures.

Flash point is almost entirely to do with transport and shipping regulations and little to do with performance or quality. I have never seen flash point used as a performance indicator.
