I was looking around the Castrol Site and found something new (to me) in the MDS. Castrol Edge PIck-Up 5W-30 SP / GF6A 100C - 10.0 cSt HTHS - 3.04 NOACK - 10.1 Flash Point - 231C Interesting it's got essentially the same NOACK (10.1 vs 10.0) despite being thinner at 100C. Also the same HTHS as Edge. Flashpoint is higher compared to traditional Edge or Edge EP. Looks kind of interesting despite my usual aversion to "truck oil marketing".
