So let me share a tiny bit of info
Base oil
Pennzoil uses gas-to-liquid (GTL) base oil which is basically a superior Group III+ engine oil. It runs a little cleaner, has a lower volatility (less burn off) and better cold temp properties.
Additives - engine oils contain anywhere from 8-16% additive to make them function
a Pennzoil ultra, M1, Castrol EDGE type will use the larger additive package (look for them to meet other specs like ACEA, MB, VW, etc.) these larger packages have more dispersants for holding sludge and soot, they have more antioxidants to help the oil last longer (we've tested out to 15k easily in nyc taxis). You're basic synthetic takes the cheapest package which I used to make by putting in the bare minimum of additives needed to meet API and dexos. That means not a cent more of cost than whatever the min spec says. So these packages treat at 7.5, maybe 8.5% of the formula where the premium product packs are usually over 13%. You need to have min treat rates when a Costco or Walmart comes to you with a bid and you need to offer the lowest cost product to them or you don't get the business.
Then there is the Viscosity Modifier.
This makes the oil work as a XW-XX oil so you get a 0W-20 by adding a polymer to it. That polymer can be an expensive one such as a star polymer which doesn't shear down (drop in vis as it gets used) and more importantly as it degrades, it doesn't leave as much deposits in your engines (mainly piston deposits). The cheap additive packs are paired with OCP as it is well cheap, they work fine but they are "dirty" polymers and tend to shear down pretty quickly.
That was my quick motor oil 101 for ya =)
BTW dirty pistons skirts and sticky rings will cause more cylinder wear which means more blowby and loss of power, fuel economy. Not much, but a few percent and it does tend to get progessively worse as it builds. More details if you want to ask, but we tested in real engines (API engine tests) to prove their sludge, deposit, wear, properties.
M1 still uses PAO in their formulas, Kirkland is Group III
Additive packages is much better in a M1 (13-16% vs. maybe 8-9% in the kirkland)
VM used is a cleaner and more shear stable star polymer vs. a cheap and dirty OCP
What does all that mean to regular people... M1, Pennzoil, Castrol all run cleaner, lasts longer, and has more additives to reduce wear, sludge, deposits etc.
Those same brands sell a similar low end synthetic oil like Kirkland though it's call Mobil Full Synthetic, those have a cheap and cheerful formula that just barely meets min specs.
Yes I know project 1 cooked the oil in a teapot and froze it but I used to make these products and run them in actual engine tests (SWRI and Intertek) and saw the difference in deposits, sludge, wear on real engine tests like the IIIG, IVA, and VG
No, I don't think kirkland will hurt your car and should easily last 5k maybe even 10k but it will definitely leave more deposits on your piston skirts, more crud in your rings, and more wear on your camshafts than some higher tier engine oil like Pennzoil or Mobil 1.

Mobile 1 is generally compared to Castrol Edge and Pennzoil Platinum.
But again, to each their own. You choose what works best for your automobile and budget.
