Mobil 1 ESP/ X3 vs FS 0w-40

Did you look at the SDS? No on here (and really no one else) will be able to or will provide that to you. ExxonMobil does not outwardly disclose the base stock composition of their products. They are, however, one of the most transparent about which approvals a product has or does not have.
The oil carries the approvals, licenses and ACEA sequences that are listed on the container. A fully-formulated motor oil isn’t defined by one attribute. As much as you seem to wish to do so there’s no real indication that this oil is any better, or worse than the Ravenol product.
it's not the SDS that provdes that kind of info but the PDS, and it just reports a generic "advanced synthetic technology", no mention about eventual group beloging...
 
Another reason why manufacturers don’t disclose the makeup of their base oils is because they are often changing them from one batch to another. So even if you did find out what a particular oil was made up of today, doesn’t mean that it will be the same way the next time you buy it. You just need to trust that if an oil has a good amount of manufacturers approvals on it that they know what they’re doing and you will continue to get a quality product.
understand, but nevertheless, several oil manufactures provide this info...
thanks to all anyway

Synthese-Technologie means it does not contain mostly Group 4 with regards to labeling laws in Germany. I pulled that from the german website for M1.
 
checked it, but did not find any relevant info
Do you know what it means? The CAS numbers and the descriptions list what the constituents are. It isn’t going to say the API Group designations.

SDS aren’t written for Group obsessed enthusiasts. I used to write them for a living, they exist for a completely different objective. Not that you can’t divine other information, but you have to know how.

I was interested in knowing which group this ESP X3 belong to, and you told me to look for this info in the SDS, now you are telling me that the SDS is isn’t going to specify this... not very useful...
