Piston deposits

[Caseymax]

Valvoline has a product that claims to remove piston deposits. The test they have passed is called adapted sequence lllH. It shows reduced deposits after 4 oil changes. All good so far.
The test engine parameter requires moderately high rpm, over 3500 for an extended period. Is this an accurate representation of how todays engines are used? My Ram at 73 mph is turning 1750.
Maybe y’all have caught this already but what do you think.

You are referring to the "Restore and Protect" product, I assume?
Been discussed ad nauseum in many threads.
Search and read; plenty to consume.
Rather than having yet another thread, we'll lock this one and if you find another that actually has merit to add to, by all means, jump on the bandwagon ...
