Ok..just so I'm clear, since there were no engine changes, how do you explain early 2018 Atlas with the VR6 (502.00) having one required grade and certification change to late 2019s which required now 504.00W 0w-30? if the argument was due to fuel economy, that can't be right as the EPA rating hasn't changed since launch. And the low-sulfur gasoline was available at launch as well. Oh, and 504.00 has been available for years?

Take into consideration that VW considers VW504.00 backward compatible. However, you really do not need in that engine anything but oil that meets VW502.00 that also has MB229.5 approval. Castrol 0W40, Mobil1 0W40 FS are both readily available, excellent oils. There are a lot of misinformation here. That engine never had any meaningful change except that for Atlas compression ratio was lowered and some other stuff not related to oil in order to be able to run regular gas. It is same engine as the one that was introduced to the US market in first generation Audi Q7 in 2007. Only difference is updated timing chain tensioner as of mid 2008.

I am just gathering information and enjoying learning about a topic that I did not know much about, while trying to find what the best oil is to put in my vehicle. Tough crowd.

Now, in your case it says in emergency VW504.00/507.00 because at that time when VW was printing manuals, the US had high sulfur gas, and that specification is not very good in direct injection engines and fuel with high sulfur (numerous threads around that, I will not repeat it). Now, the US has ULSG, but still VW 502.00 is OK as that engine was developed around that specification. Also, stop blindly believing dealerships. Hyundai literally recommends specifications that do not exists for their engines. Go to local Wal Mart, get Castrol 0W40, call it a day, enjoy the ride.
Mine is a 2019 and in the book and under the hood it says 502.00. My book says that in an emergency you can use 504.00. The parts guy at the dealership said specifically Castrol Edge 0W-30 502.00 and I gave him my VIN #. I don't know why I would trust the Mobil 1 oil selector over the dealership because yes the Mobil 1 site says to use there 0W-30 that is 504.00 approved. I never imagined this post would blow up like this. Who knew it would be this much ambiguity with oil! LOL The dealership did confirm what was mentioned earlier in this post that VW was dropping Castrol and moving to Mobil so mabye Mobil doesn't have a 0W-30 that is 502 approved and thats why they push people to the other?
