Mobil 1 Advanced Full Synthetic High Mileage 5W30 vs Mobil 1 Extended Performance Full Synthetic 5W30 - new oil analysis

[DIY4quality]

Attached are new oil analysis for these two Mobil 1 oils. I also included docs from the Mobil 1 website showing specs for each respective oil.

As of the date of this posting, Walmart is selling a 5qt jug of the Adv for $22.37, and a jug of the Mobil 1 Extended Performance for only two dollars more at $24.37.

Thanks for posting. To my untrained eye the AFS looks to be the better product with higher key add packs? Am I mistaken?

Which flavor of the oils will provide my engine with the least amount of wear per mile ?

EP might need less additives because the base oil is better.

Thanks for sending in and posting. I'd agree there is likely and edge in the base stocks to accommodate longer runs for EP.

The VOA results are so close to be almost the same when you consider sample variance.

The specs on the website show a significant difference in the viscosity where Adv (11.9) is higher than EP (10.6). However, the VOA results contradict this where Adv (11.2) is slightly lower than EP (11.4). Again, almost the same.

The price difference of $2 for 5qt is very small and does not reflect any substantial difference that you would expect if the base stock were really different. I don't know what additive costs a couple bucks to double the OCI from 10K to 20K miles.

I'm hinting at a conclusion that I'm not openly stating.

Is this the HM variant of EP? The UOA hints that it is but the topic title does not.

Yes, both of these VOA's are for the HM variants.
