I asked Mobil for their latest M1 SS NOAK %'s for 0w-30 and 10w-30. cSt is one way to help consumption but NOAK is related to this as well although in a new engine, anything below 10% is very good IMO. In an engine that is older like mine a 10w-30 is a better choice. * To those that rip M1, look what they are giving you for $-4.50qt. A fully PAO/ester oil with a TBN of 12 and very good low volatility. I'm NOT saying its the best oil but you have to admit that ExxonMobil makes and delivers a great product at an affordable price. 0w-30 is 9.9% 10w-30 is 8.8% These are actually excellent numbers, but Amsoil's are incredible. S2k is 8.8% ATM is 5.2% [ November 03, 2003, 02:27 PM: Message edited by: buster ]
And Havoline 10W30 is <5%. What does that mean? Well the high M-1 evaporative number explains the tri-sin theory. Sin #1 Use a very light PAO base oil. Sin #2 bring the viscosity up with a small amount of a very heavy PAO or super syn. Syn #3 Add an ester additive carrier.

Unfortunately no, and since getting technical info from Castrol is like pulling teeth, I doubt we'll ever know this info.
