In the Q&A section, they flat out say the TSUV oils have more AO's. I've said before that this could be why Shell/Pennzoil don't market PP/PUP for longer drain intervals. This is what separates the Mobil 1 AP/EP from the rest of the crowd and why you're paying a premium for an oil designed for longer OCI's. With that said however, I'd have no issues at all running any Shell product as I know they are very good quality.
I am of the opinion that oil is oil and labels like "extended performance" are just marketing gimmicks just like the "gas truck" label is. I think Shell is most interested in producing a simple line of products that has the widest appeal per individual product so to minimize overproduction. I mentioned in another thread that Mobil produces six different 0w-20 oils and I just don't believe there is much difference between any of them, I think RGT 0W-20 is marketed to match up with most if not all six of those products.
I think most consumers that will buy Shell or Mobil products are going to follow OEM recommendations for an OCI because many will want to maintain a warranty of just don't want to get into the guesswork of doing an extended OCI. No need to produce a half dozen different variations of the same product when one will meet the majority of customers' needs.
They're not marketing gimmicks. I've seen oxidation tests of oils like Mobil 1 AP/EP vs the competition. With you, you're generally getting what you pay for. You're right about oils such as TSUV etc., although they do contain added AO's.
Perhaps a better way for me to put it lies in how much incremental difference there is between all 6 Mobil 1 0w-20 oils versus how many of those bases Rotella Gas Truck would cover with one single 0w-20 oil. Also from the research I have done as well as the fact that I have used multiple variations of Mobil 1 0w-20, primarily AFE & EP, I don't see much difference.
RGT is a direct competitor to Mobil 1 AFE, TSUV, amd HM. M1 EP & AP are products that tout longer usage intervals amd I would agree that their oil content is likely of a higher quality and performance yet is it enough to compel a customer to pay $35 fot a jug of AP vs. $22 for a jug of RGT?
I am a big fan of M1 EP 0w-20, if we take rebates and other promotional incentives out of the equation that is one oil I might pay a few bucks extra for over RGT.
