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).

Go with the 4-cylinder recommended oil.
I used the Liqui Moly Volvo-spec VCC RBS0-2AE approved oil in my XC90 T8:

Thanks a lot!
Found this thread (after posting, although I wanted to check if Polestar was any different, so probably would have posted anyway):

Also this thread:

That being said, I should have probably mentioned in my original post (thought came to mind now) that I am referring to topping off the engine oil (if / when needed) between dealer oil changes.
Given that and not knowing which oil the dealer(s) use(s), I wonder if I might be better off using 5W-30 Castrol Edge Professional to top off the oil, assuming the dealer likely uses 5W-30 (and not 0W-20)???
That way I am less likely to be mixing oil types when I top if off (if that matters?).
The photo below is from under the hood.

So I got the answer for my email from Volvo

Hello Joseph,

Thank you for contacting Volvo Cars USA. I hope your day is going well. 5W-30 is recommended in the United States over 0W-20 due to the fact that 5W-30 is easier to locate in the United States than 0W-20. Hope this helped, thank you.

Med vänliga hälsningar!

Yours Sincerely,

Todd
Volvo Car USA

That's correct and Volvo on it's US version of it's User-Manual do recommend the 5 and 6Cyl S60 to use 0W30 for Extreme driving conditions (Artic temps, Towing, Racing, ...).
But for the global market again it only recommends the 0W20 RBS0-2AE oil even for the Polestar!

All that made me come to conclusion that the RBS0-2AE certifications might means Volvo Engineers played with the oil charachertistics and specs to have the protection of 5W-30 and operating Tempratures of 0W40, same case with some Audi and BMW OEM certified oils they were talking about the same on bobistheoilguy.com forums.(Oil talks forums)
Also they were talking about the RBS0-2AE oil specs (Vis.Index,Oil Flash Point,...long spreadsheet with many numbers) and how that oil is in a hybrid category between 5W-30 and 0W30.

I switched to the LiquiMoly at 2000 miles on my XC90 and have exclusively been using it. The 0W-20 is readily available in the US and I see no reason to use another oil for the 4-cylinder engines.

You shouldn’t need more than 1 quart in between oil changes for topping it off, so you use whichever of the two you are more comfortable with.

Yes the 0W-20 Volvo RBS0-2AE is the official oil for the S60s it's custom-designed for Drive-E engines

But it's not available in the US "Due to regulations requirements" and they made the US user manual based on that.

All world Volvo Markets user manuals lists 0W20 RBS0-2AE as the only oil for the Drive-E engines except the US it lists the 5w30. (You can check the other countries manuals yourself online).

When reached to Volvo US customer service they confirmed that and they said since that type of oil is not available in the US market they use 5W30 as an alternative in their car service.
I personally purchased (Liqui Moly 20200) 0w20 RBS0-2AE online.

did not know about this specificity due to US restrictions
@volvjoe: where do you purchase your oil (website)?

Location(website) of purchase varies actually depends on the price and offers that I find, Last time I purchased it from Autoplicity.com they had a discount and I got the 2 of 5L for $28.99 each but I just checked and the deal is no longer there.
Just google Liqui Moly 20200 and go with the cheapest offer, it comes in a sealed container so just go with the lower price offer.

A quick search on Google gave me those results, some search results give a generic oil container photo which is fine as long as the brand name\model is correct:
