Is a pour point of -54C a fingerprint for high PAO content? Please post links or reprints of MSD-sheets from the past if anyone has access to them. I want to see how many older/ current synthetics had -54C as a pour point. Then I'd just like to have a civilized discussion about it. That's all. I know GC is still at -54C and everyone claims it is a high PAO based oil. I believe a lot of the older Mobil 1 oils were also -54C but I can't find any MSDS from the past. Let me clarify: - I mean exactly -54C. Not -53, -65, -48 etc. - "lower" being a larger negative number so that -75C is lower than -54C. Higher obviously the opposite. - Not interested at all in how pour point depressants can lower pour points beyond -54C. That is another conversation.
