For their 5W-30 Advanced Full Synth HM engine oil, Mobil 1 publishes a flash point of 245C/473F on the product specs. This is significantly higher than other Group 3 oils, and even higher than some Group 4/5 oils.
What are they adding to achieve this impressive flash point? Could whatever they add sustain this high flash point over the life of the oil while in use, or is this high flash point just characteristic of brand new virgin oil?
