PUP did "better" according to those parameters.
What parameters exactly? Did he clearly define those parameters, or did he have his "instrumentation" professionally calibrated? Did he perform any ASTM tests?
I don't see any favoritism.
Project Farm is an influencer. Now, the FTC offers clear guidelines about the disclosures influencers must make about their connection to whatever brand they are advertising. You can read what those guidelines are here:
https://www.ftc.gov/business-guidance/advertising-marketing/endorsements-influencers-reviews
There are simple ways around those disclosures, like using a third party. No one would ever care enough to look into Project Farm's videos more than we did here. That doesn't mean that, at the very least, we shouldn't point out the facts.
The fact is, every oil that PF tested is API certified and would do just fine in cars they are spec'd for.
Yes, all motor oils were API licensed in the video discussed in this thread. However, the video intends to steer his audience to purchase the Pennzoil Ultra Platinum product. That is because it's the poorest selling oil in their lineup, and they don't exactly want to give it away.
Pennzoil Platinum is the same product as Shell Helix Ultra SP. This product is blended the same way everywhere in the world, meaning it's a mix of Group III and GTL base oils and an Infineum Dexos 1 G3 API SP additive package. Therefore, it receives the most amount of testing and attention from Shell. Pennzoil Ultra Platinum is blended using only GTL base oils, and it's mainly an outlet to sell GTL overproduction. It uses the same Dexos 1 G3 additive package, which his basic oil analysis did not reflect. The Pennzoil Ultra Platinum in his video uses the old Dexos 1 G2 API SN Plus additive package (high Boron ppm count). I don't even know where he found this oil in stock. And right there, another flaw in his test: he should have sampled multiple batches from each product line.
Oh, his video's Pennzoil Platinum additive package was skinny, almost diluted. I'd love to know how he accomplished that.
@RDY4WAR's excellent steak comparison notwithstanding,
@OVERKILL made once an excellent observation about Project Farm's motor oil videos:
I'm paraphrasing here: "Project Farm's motor oil comparison videos are about as effective in determining which one is the best as is using riffles as hammers to determine their accuracy."
