How do these two premium oils stack up against each other?
Amsoil Signature Series 5W20 vs Pennzoil Platinum

Well, one has proof of performance by actually carrying certifications and approvals. As far as I can see the other one does not.
That's what's important to me, maybe it isn't to others. It looks like one is significantly less expensive than the other as well.

Amsoil SS can go 25000 miles (see link below). Pennzoil says 15000 max.
Amsoil SS costs ~$10/quart (when including their club fee). Pennzoil costs $5/quart.

Unless something has changed that I missed, Pennzoil only recommends that you run the oil as long as is suggested in your owners manual.

While I'm sure Amsoil's good stuff, I don't understand why people use it. The marketing and sales tactics are annoying scams, many (not all) of the dealers are pushy tools. And with the high standards engine oils are up against these days, all the over-the-counter options perform exceptionally well and even better than Amsoil is some instances, best part is these oils are available EVERYWHERE while Amsoil is only available through dealers or over online stores.
Many UOA's I've seen of the SS oil run all the way out to the 25k mark showed the oil's TBN had depleted to dangerous levels a few thousand miles before the 25k mark. Personally, I'd rather run my Pennzoil and change it more often than risk costly engine damage running Amsoil out to 25k like a lot of people do. It's your money, and you can't go wrong either way since both are good oils, but based on availability and ease to find, Pennzoil's where I'd spend my money!

Really depleted TBN and high ppm wear metals per 1000miles?
Odd I haven't seen any.

PP is a paraffin. Amsoil is the proven PAO and Ester blend. But I do Plan to try PP again this summer now the rogue is broken in. Wasn't plussed with it in the past but I wasn't accustomed to how cold blooded and rackety the Rogue is below 0C. All Aluminum thin castings and Simple DOHC with inverted mechanical bucket tappets makes for a racket. Also theres Injector racket would be at home on a diesel. Its embarrassingly loud.

Where do you see that in Amsoil literature? What I see is this:
Quote:
What kind of base stocks does AMSOIL use? Are AMSOIL synthetic lubricants PAO-based?
Answer: AMSOIL maintains formulation details as proprietary and does not divulge specifics regarding the type of synthetic base stocks used in its synthetic lubricants. AMSOIL developed the world’s first API-qualified synthetic motor oil in 1972 and has remained the leader in the synthetic lubricant industry by continually researching new technologies and demanding only the highest-quality raw materials. As the company moves forward with new technologies it is increasingly more important that this information remains proprietary. AMSOIL views synthetic base oils the same as it views additives, with each having its own set of unique properties. AMSOIL does not insist on a particular type of base stock, but insists on particular performance parameters. AMSOIL chooses whichever synthetic base stock or combination of base stocks delivers the desired result and tailors its lubricants to be application-specific (gasoline, diesel, racing, transmission, gear, extended drain, extreme temperatures, etc.). At the end of the day, the type of base stock used to formulate the oil is inconsequential; the product’s performance is what matters
That could be the exact same Group III stock as in the Pennzoil. Or maybe not even GTL Group III.
To me it's irrelevant and I couldn't agree more with their last sentence. I would not (and don't) buy oils based upon supposed base stocks. I buy an oil based on the certifications and approvals that it has demonstrated to carry. Anything else is rank speculation - as your supposition and the actual Amsoil claim demonstrate.

Here's several links. The TBN is above 3 in this one, so it survived the full interval:

Here the TBN is almost gone after just 10,000 miles:

The TBN is gone on this sample. Should have been changed at 15000, far short of the 25k amsoil promises:

Unless I'm mistaken, PP is not paraffin based. It's GTL.
The processing removes a good deal of the wax.

The intermediate product from the gas to liquid conversion process is called a paraffin. It is just a saturated hydrocarbon chain. Not all "paraffins" are a wax. What specific chain lengths and branching structures are desirable for motor oil I do not know, but Shell does.
A better term might be a synthesized paraffinic base oil.

COMPATIBILITY
AMSOIL Signature Series Synthetic Motor Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.
SERVICE LIFE
Normal Service – Up to 25,000 miles, 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under Severe Service.
Severe Service – Up to 15,000 miles, 700 hours of operation or one year, whichever comes first. WHY DOES EVERYONE LEAVE OUT THE UP TO ?

Since conventional oils apparently meet API specs, but aren't appropriate for long drains in most cars, meeting API isn't particularly important in my book; I like to pour in some oil and not worry for 9-14K miles (1+ year for me) Since I have been doing that with SS oils for a few years, I'm confident of their LL ability.

The last one is OE. This thread is not about OE oil is it? BUT I am glad you posted that. It is MUCH better to compare Amsoil OE series to PP.
Then you call a TBN of 3-4 "almost gone".
Please. Some of these have been in the crankcase a year. None of these are example of "shot" sig series.

Exactly. Thank you for slogging through that, I saw it too but didn't care enough to respond.
