I am in the Northeast USA (NJ) and have a 2018 S60 Polestar (4 cylinder engine, not 6 cyl.).
I was thinking of using SAE 0W30 engine oil based on attached engine oil recommendation from the S60 manual (under 'Extreme Engine Operation'), which I assumed is for 4 cylinder models (since every S60 model that this manual is for is 4 cylinders anyway), till I read the extra box also labeled ' Extreme Engine Operation' mentioning '4 cyl models only: Volvo Oil VCC RBS0-2AE/SAE OW20.
So, unless I am not interpreting it correctly, there seem to be 2 DIFFERENT 'extreme engine operation' recommendations for the same (4 cylinder) car, how do I know which one applies...?
Thanks in advance for any oil viscosity recommendations!
Hopefully someone can explain the TWO 'extreme engine operation' recommendations...
Side note - I am not planning to drive in ultra cold, so I know 5W30 is also listed (albeit not under 'extreme engine operation', whatever that means).
