In 2015/2016 when some of the newest Quaker State Ultimate Durability was tested, it came out with as much moly, boron as the Pennzoils. Interesting that Quaker State Ultimate Durability 5w-20 and 5w30 tested out near the very top of all oils in 540Rat's methodology. While that doesn't mean a ton, it put the Quaker State Ultimate Durability above the Pennzoil Platinum and on par with Mobil 1.
