This looked quite interesting:

I then read a couple independent reviews of it on eBay and Amazon... majority of the reviews seemed quite good (of course, except the 1 and 2 star reviews, which seemed quite bad/scary ..perhaps anti-marketing from competing companies though?). I also quickly Googled it and incidentally read one poster/thread (a Honda B-series swapped Civic guy) that said he spun a rod after it.

Has anyone used it? Did you notice any improvement?

I'm scared to try it (but I'm also interested to try it), because we all know our F-series engines are sensitive to sudden oil-brand/type changes, and it's better to stick with the same oil-brand/type you've already been using for a while. I don't want this to cause any new leaks, mess with the seals, spin rod bearings, etc.

Gonna stay away from the merits of oil additives but did quick look at the Amazon reviews and used "Fakespot" which is a chrome plugin analyzes reviews for signs of fakes, etc.. and the rating for reviews of this stuff is a "C":

Anyway, caveat emptor

Our engines don't need any of this stuff.

Put in literally *any* synthetic with the proper weight, change religiously at 5-7.5k miles, use a new PCX filter each time, and that's it! Move on with your life and worry about things that actually matter!

Manual says that you can change the filter every other oil change under normal driving. The construction of the pcx filter is even better than those extended service filters from Mobil 1 which last 15,000 miles. So swapping s2k oil filters every 10k miles (5k mi oci) shouldn't be an issue.

Naturally if you're tracking it's severe service so you'd change filter and oil each event.

We have people on this forum with more than 200,000-300,000 miles on the car. Take care of it in a straight forward fashion and it will take care of you. Forget the snake oil and Nigerian Prince get rich scams.

To be fair not many of us are willing to install a pre oiling system so the car always starts with oil pressure. However these engines are pretty bulletproof as long as you maintain them. When I hit 220k with mine I'll do a refresh(timing chain, rings, some head work), or just swap in something I've been working on.

remember the slick 50 commercials where they dumped water and dirt into an exposed valvetrain and an engine with no oil in the sump ?, it looked impressive but you can make anything look good if needed.

My experience is that if you do ordinary oil and filter changes (in fact even if you are sloppy about that) its not the engine that ends the life of a car or truck. Its all the other stuff.

Often in our quest to preserve something, we end up hastening its demise.

In this case, trying to solve a problem that doesn't exist, you can easily do more harm than good.

As far as I'm aware most snake oils will only make your wallet lighter. If there's an issue with this engine none of them will help you. Considering the specs allow .009" of play on the exhaust guides (this is loose as hell), if there is an issue it's well past the point snake oil would do any good.

Same goes for high mileage oils. Often times those seal conditioners end up making leaks worse. Best practice is simply to stick to a brand of oil, and do the changes on time. If seals start leaking replace them, save for the rear main seal, they're all pretty easy to replace.
