Sea Foam - Snake oil or not?

[Ducklakeview]

Ok, before you all start!

Normally I am the pessimist when it comes to stuff like this. I don't for instance believe that Slick 50, Molyslip and even Redex are worth paying for..

Probably the ONLY "additive/cleaner" I have ever been imprssed with, is Liqui-Moly's "Diesel Purge" which you actually run the engine on by disconnecting the diesel supply and inserting the pump flow and return into the 1L can and running it until it's gone - Brilliant results.. Anyway, I digress..

My van, a 2010 Scudo has done a few miles now, 215,000 to be exact. Noticed it a little bit "rattlier" than usual, so was looking at this stuff; https://seafoamsales.com/sea-foam-motor-treatment/

Now, try as I might, I just cannot seem to find a bad review on it, so was wondering if anyone had used it?

Thoughts?

I'm fairly sure we discussed sea foam a while back after a few of us had our cars carbon cleaned at a show. Don't recall anyone actually trying it though, but we did find carbon cleaning to be a little short lived in it's effects.

all a bit snakeoil in my mind

There are a few videos in youtube where a guy looks with a scope before and after. There were 'some results' but you have to wonder why someone would do it with minimal impact as an end result.

Here's the video that @Cooper is referring to (I think)

In the past, cars had to be "decoked" as part of the service regime. Upper cylinder lubricant (shots) was available on petrol station forecourts, one squirt to each (leaded) gallon was recommended as I recall. Lead was of course added to protect the valve seats and "stuck" to the head and of course piston tops etc. With modern unleaded petrol (and hardened valve seats), decoke shouldn't be required.
