Can a fuel additive clean piston rings?

Question: Will a fuel system cleaner, with PEA, have a meaningful impact on reducing the clogging up and sticking of oil control piston rings?
I have a 2011 GM 2.4 Ecotec with 142k miles in an Equinox that is known to be prone to excessive blow by, none yet, due to sticking rings. I want to be proactive to prevent mine from doing this but I've been thinking in terms of oil brand, oil additives, engine flushes etc. not a fuel treatment.

I have used Gumout All in One and a product from Redline with PEA occasionally, maybe once a year, but for the injector cleaning properties.
I've never exceeded the oil life monitor for changes, I think it's set to 5-7k miles but IDK and used mostly full synthetic oil, except when the dealer changed it. There's dozens of YT videos of this engine developing blow-by due to stuck rings and plugged PCV system. I've decided to ignore the OLM from now on and go with a 3,000 mile change but I'm thinking I should maybe start using something like Rislone oil treatment to help keep things clean. Maybe a fuel system treatment regularly if that would help. I try to use top-tier gasoline most of the time.

I bought one of those bore scopes so I can take a look inside the engine but haven't had the chance to use it yet. I also changed to a vented oil fill cap with a check valve and added an oil catch can. I don't think the catch can is serving any purpose yet because so far my PCV system is working properly.

I really can't afford to replace this car or pay for a major repair if I can avoid it.

Thoughts?

It's highly unlikely that any cleaning around the rings will occur from fuel additives.

For the rings, you'll want an oil supplement like High Performance Lubricants SAE 30 Engine Cleaner.

The only one I know of and I know others will chime in with other products is Auto Rx Plus. I run it in my Volvo every 60K miles to clean up the interior of the motor and de-carbon the piston rings. Some have opinions on Auto-Rx here on this board but when something works and does as it says I'll keep using it. It is an oil additive that you use when you change the oil. Add to the new oil and drive for around 4,000 miles and change the oil and run another 4,000 miles as a rinse phase.

I would recommend changing oil at respectable intervals using top tier fuel and running a bottle of Chevron with techron or stp each oil change.

I have had luck doing a “Kreen piston-soak”. The stuff is like impossible to get nowadays unless you go through a distributor.
GM makes a top engine cleaner that I hear is very good.

I received 2 quarts of it the other day. I think I'll use it in my next two oil changes and see how it does.

Most can't handle popping their hood or using a tire PSI gauge... and some want them to handle DMSO, or follow a flush procedure, or piston soak procedure...... many won't even follow simple advice of exercising the dipstick more often or adapting their OCI, grade or type, to the automakers horrible R&D.

We knew long ago. Purposely don't care for the masses to use or even know about DMSO. They are better off with 5-minute solvent flushes and shorter oil change intervals.
