I did read the title of the thread, and then I read the opening post, which ascribed a massive improvement in fuel economy primarily to the lubricant. That's what most people are taking issue with. I have no idea what you are trying to say with the last part there

There are just as many, if not more, recommendations for Pennzoil. All the majors are pretty broadly represented in recommendations IMHO. You may state with confidence that this oil would be the best, but you cannot actually prove it, it's simply your recommendation, as you lack any sort of formal testing proving that assertion.

Nobody is cherry picking from what I can see, and certainly nobody needs to actually use the product in question to doubt the validity of claims that are outside the realm of what's possible. That doesn't mean that it isn't a good product, it simply means that one needs to be cognizant of what constitutes a reasonable expectation from something as basic as lubricant selection.

There are myriad externalities that can have an effect on observed fuel economy, which is what people are saying here, and the ability for an oil to impact fuel economy by the amount claimed simply isn't possible. I'd say the same for additives too, as realistically, if economy could be so dramatically affected, OEM's would be all over it to improve their CAFE numbers, which impact their bottom line.
The use of higher octane fuel, which may lead to more ignition advance and thus an increase in economy is yet another factor. Engines with higher compression ratios but rated for 87 octane to garner more sales may experience an improvement by running a more knock-resistant fuel that allows for a better timing map.
