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%
