More specifically, which readily available, off the shelf oils that you would buy at Walmart or the auto parts stores are actually Group IV PAO Full Synthetics?

I found some older threads that sort of contradict each other, and I've noticed lots of oils have changed packaging, names, and possibly formulations pretty recently.

Regardless, I will likely continue using Pennzoil Platinum or Ultra in my Focus, as they meed the SN, GF-5, Ford, and Honda/Acura Turbo ratings and I can find it easily and inexpensively local to me.

I'm mainly just curious which oils actually are true Group IV currently, with the current names/bottles/formulas as of Spring 2018.

You will not find one oil on the market that is 100% group IV simply because some group II+, III or group V oil is needed for additive solubility. Closest you will find to that magic all group IV you seek will be something like Amsoil Signature Series or one of the European/German-manufactured oils that say Vollsyntetisch, and not Technosythese. For cost savings without much performance hit, most majors are using group III majority base oils with whatever additives are needed make the required spec. You would probably find some syn oils sold in Canada with higher percentages of group IV/PAO due to the need for best in class cold cranking ability. I'm guessing, but probably the oils labeled for longer oil change intervals such as M1 EP and M1 1year/20k mile oil probably have higher amounts of PAO than their less expensive blends such as regular M1.

The only one I knew of was the Royal Purple Synerlec oil,which they themselves told me was a pao base with a dash of grp II as a carrier. I liked the fact they didn't give me that "It's proprietary" b.s.,they actually gave me a straight answer. I wonder if the HPS and XPR oils are carrying that same formula?

Any over the counter oil is at least 10% Pao because it has to last at least 5k ocis.

You failed to mention synthetic. So you're saying conventional has 10% PAO?

When was this? Recently? I had inquired about the composition of their base oils for the HPS and XPR line about 2 years ago and was told it was proprietary information.

Gosh it was probably 10 years ago,long before the Calumet buy out.

None are.

BMW tech guy nailed it.

The Mobil 1 15K and "annual protection" probably have the highest % of anything you see at walmart.

Amsoil sig series probably a bit more.

Ya, sadly they will not tell you that information anymore. I suspect it has to do with the fact they have started using Group III for their base oils. I still love their oils though!

I'm not sure where you are getting that "fact" ? TGMO is entirely group III based for example, no PAO. I think you'll find quite a few oils; like the majority, have zero PAO in them.
