What Kirkland/Amazon/Walmart do is buy a "market general" product from Warren that is made using a very basic additive pack (API SP/dexos1), a standard group III base oil and a cheap OCP VM. These products are what we formulated as bare bones, vanilla products which means you put in only enough additive to meet the absolute minimum spec requirements. Additive treat rates 8-9%
A Mobil 1, Pennzoil Ultra, Castrol EDGE are all proprietary products that these companies spend millions to develop. They use almost 2x the amount of additives, (around 13-16%) Plus Mobil still uses some PAO which is group IV. They also use a cleaner star polymer which lasts longer and burns cleaner.
We test these products in actual fired engine tests for piston deposits, sludge, wear, among others. These are the tests GM approves for dexos for example and in the "market general" product the piston deposits are pretty visible but passing (low dispersant content, dirty OCP viscosity modifier) and in the "premium" products they are almost new looking thanks to much higher dispersant loads, more antioxidants, and of course the star polymer VM which burns cleaner.
Now to a regular person sure they all seem similar as you don't tear your engines apart, and if you trade your car in every 3-5 years, it will not matter to you, but for people with turbos, or keep their cars longer, these "premium" engine oils will make your engines and turbos last longer and maintain their fuel economy and power longer.
I used to make these products before I retired so feel free to ask questions if you're curious.
Pennzoil Ultra Platinum should still have around 1000ppm calcium most engine oils meeting GF-6 LSPI have around a 60/40 split of calcium/magnesium detergents to prevent Low speed preignition or engine knock. Only the older API SN and older were mainly all calcium formulas with maybe 1500ppm calcium and no magnesium. (Mobil 1 and Castrol EDGE always had magnesium even in the old formulas). That said it should easily meet GM dexos1 but just so you know GM charges a royalty fee so for every product with dexos on the label you pay a % royalty on sales... we used to hate that as it was a cash grab from GM on a spec that was only slightly higher than API. That said almost anything meeting API SP would likely meet GM dexos1.
I don't really want to weigh on on Pennzoil vs Mobil 1, I'll just say both are what I call premium engine oils meaning they use high levels of additives (more than spec min) and clean VM. Pennzoil uses a GTL Group III+ base oil which I know tends to run a little cleaner than regular Group III+ base oil. Mobil 1 however still uses what looks like 20-30% PAO which is very cool in my book as PAO is still my favorite. Personally I'd be fine using either.
For those niche oils like Liqui Moly those meet euro spec it is a very good product and meets all of the top OEM specs like VW, Porsche, BMW, MB etc. so top of the line additive pack and it seems like it could contain 10-30% PAO so definitely a great oil. my old coworker swears by it (has a VW).
Amsoil... I'm not so sure, they're a little like the wild west to me as they do what they want which means crazy additive packs, race oriented products which are vastly different than mass market car engine oil. I'd say good but take it with a grain of salt as if you use a high zddp oil in your new car you might kill the catalytic converter early (ask me how I know lol, rookie mistake).
Hope that helps, FYI that's just my opinion.
oh one last note, if you see a product meets ACEA, MB 229.xx, VW 50x/50x etc. you''ll know it's a top tier engine oil with a very strong additive package and probably uses the expensive, cleaner VM.

Does Pennzoil Ultra Platinum have calcium in it? It is not have Dexos approved, and I was wondering if that was the reason why. In your opinion what do you think is better, Pennzoil Platinum or Mobil 1? What do you think about Amsoil and Liquud Moly?

Ignore the oil snobs. It's all the same with minor changes due to different manufacturer additives that make little to no difference. What actually matters is oil change interval. Change your oil every 5,000 miles. Ignore the fools who say you can go 10-20k between changes. I had a brother in law argue with me about this to no end. Last year he destroyed an engine with less than 100k miles. Guess who changes his oil every 5,000 miles now?

I have a 2000 f150 with a turbo. Truck is babied and I change full synthetic oils every 3k miles. Sometimes I use mobil 1 or Kirkland, depending on where I can get the best deals. How much of a difference does Kirkland vs mobil 1 make in my case where the oil is changed at such low miles? Thnx in advance

Castrol EDGE vs Mobil 1?
Does Castrol EDGE contain equivalent amount of PAO vs Mobil 1? EDGE (5w-40) still has the BMW LL-01 rating whereas it was dropped from Mobil 1 products. I have noticed the engine runs quieter/smoother on EDGE; louder ticking from valve lifters on Mobil 1
I don't think the variants matter. It's just marketing for tiny differences in the additives. It's more important to get quality oil (like this) and use the right weight.
Looks like expensive is better:
Advanced is more damaging to engine's catalytic convertor than its competitor.
Extended is the best contender for reducing sludge and cleaning purposes.
At high-temperature conditions, Advanced would burn off more quickly than its rival and Extended would be the best option in high-temperature conditions.
Extended has remarkable wear protection ability.
The better option in cold weather conditions would be Extended since it has high value of pour point than its competitor.
Oil change frequency of Extended is higher than its rival.

Thanks for the explanation. Honestly, my dad and I have used Castrol's Magnatec initially for years (also a lower end product) and then switched to Kirkland for the last decade or so in our Accords respectively with no problems. His car is over 200k and I'm at 155k. Both engines run perfect on "lower end" oils. As long as you're buying from a major brand, my philosophy is that you will be fine as long as you change your oil on time... (every 5k or once a year is what we've been doing)

I don't believe so, but it is a good product (euro formula) and Castrol used to have a neat way of formulating with a higher base oil viscosity (BOV) so their engine oils were a little thicker even before the additives got in. Maybe that's what you're hearing? I know some of the Castrol euro stuff was full PAO but I can't recall which grade (came from Germany) but the 5W-40 doesn't seem to be that one. BMW guys used to go nuts looking for the German stuff.

I didn't know the 2000 had a turbo engine? Like aftermarket? For most turbo engines I'd probably stick with the cleaner star polymer products (M1, Pennzoil, EDGE) as they just don't leave as much in deposits in that turbo bearing. You can leave those oils in there easily for 5k or more though if that helps your budget. Turbos are just really hard on oil and that cheap OCP VM just tends to leave residue as it degrades regardless of age of oil. That said, your 3k oil changes I'm sure are helping to keep it clean so either or but if it were me, I'd used premium stuff on a turbo. Plus if you're talking an ecoboost 2011+ 3.5 and 2.7 we did see some issues on those turbos with coking in the bearings.

Haha cool glad to hear. Yeah Magnatec was a cool product had this neat waxy additive that would coat your engine when the oil cooled, reduced wear to almost nothing on the Sequence IVA wear test. You're right on just keeping up with the oil changes hope you get many more miles out of them! Although you have a ringer (as do I Toyota) so we can run these things on vegetable oil and they'd go on forever.

We test these products in actual fired engine tests for piston deposits, sludge, wear, among others. These are the tests GM approves for dexos for example and in the "market general" product the piston deposits are pretty visible but passing (low dispersant content, dirty OCP viscosity modifier) and in the "premium" products they are almost new looking thanks to much higher dispersant loads, more antioxidants, and of course the star polymer VM which burns cleaner.
Now to a regular person sure they all seem similar as you don't tear your engines apart, and if you trade your car in every 3-5 years, it will not matter to you, but for people with turbos, or keep their cars longer, these "premium" engine oils will make your engines and turbos last longer and maintain their fuel economy and power longer.
I used to make these products before I retired so feel free to ask questions if you're curious.
