Run Like New is a marketing term. Truck & SUV is also just marketing terms unless it specifies DIESEL Truck/SUV.
Diesel oils have additives made for diesel engines (like zinc and sulfur) because they don't use the same catalytic exhaust system as a gasoline engine. Running diesel oil in a gasoline engine can ruin the catalytic converter.
It's rated for Dexos R now and upgraded to API SQ.
Hint: The A is for American oil standards. They just certify the Euro batch with slightly different additives to meet Euro brand specs.
Mobil 1 Euro / FS is actually one of only about eight approved oils for the Corvette, and L87 V8's that don't need to be replaced.
P.S. It's a great oil. My go-to now. Going in my roadster this month.

Not everyone has a beater car.
People do drive cars that Engines cost $20K,$30K,$40K, $50K or more to replace.
Kirkland like others, don't meet all specs for all engines.
Very, very few cars out there call for more other than that.

"General
We operate membership warehouses based on the concept that offering our members low prices on a limited selection of nationally branded and private-label products in a wide range of categories will produce high sales volumes and rapid inventory turnover. When combined with the operating efficiencies achieved by volume purchasing, efficient distribution and reduced handling of merchandise in no-frills, self-service warehouse facilities, these volumes and turnover enable us to operate profitably at significantly lower gross margins (net sales less merchandise costs) than most other retailers. We generally sell inventory before we are required to pay for it, even while taking advantage of early payment discounts."
This is more readable then the sec filling:

"Costco distinguishes itself by passing a significant portion of its economies of scale back to its members through consistently low product prices, maintaining a markup of no more than 14% (15% for Costco's private label Kirkland Signature), with a target of 11% on Costco's total cost of goods sold."
That massive moats site has no sources and looks AI written.

Unwise. Additives deplete and base oils breakdown and wear/sludge/etc can rise suddenly outside the interval for the product. Trace metal analysis isn't the whole story.
