Ya for adjustable. A bit less for non adjustable. I will pay an experienced guy who can get it about perfect on the first try. I have no desire to learn shock tuning.
Has anyone taken a Rancho RS9000 shock apart?

We used to tune shocks at the shop I work at and it’s never a one time thing. As you know it’s a seat of the pants thing. It’s all about tuning your ass really lol.
The valve tuning is poor I agree! A thinner oil should pass faster through the orifice on the adjuster and the shock. If 5 wt is the oil used a 2.5 wt oil and the same nitro pressure should make some difference. It’s all theory tho.
@jjvw’s idea to warm them up to see if your idea is even plausible is a good one. Get them up around 150, 175 degrees and so for a quick spin. You should be able to tell right away if the lower viscosity will make a difference
You also might pull the adjuster apart and look into modding that. A bigger orafice for the needle will flow more oil. Basic carb tubing theory.
You make have to machine a new needle and seat though…not sure if you have that capability.

The two very best shock tuners I have ever met in my life don't ride in the car to tell you exactly what you need. And I have never seen them make any adjustment with oil.
This experiment seems like extreme turd polishing with no true measured result.
The only thing you are going to change is where/when the shock is bad.
There is a lot of Nay Sayers out there. But if we always listened to them, we would never have any fun. Hopefully you follow through with this, post something, like a video and so we all can learn a little.
Lol thanks if I listened to everyone that says it not possible on this forum. Than I never would have done a lot of things on my jeep. Pre this forum and internet was a lot more wild from what I remember! There is no downside for me. I’m gonna learn something either way.
I’m pretty sure they were frozen when it was -16 a few weeks ago. They felt an exactly the same by the way.
That might tell you what you need to know about this endeavor and why we don't seem to see shock tuners tune shocks with oil viscosity.
Like it or not, you are attempting to change the behavior of the shock. This means you are tuning the shock. And it is entertaining how resistant you are to calling it what it is, as though that somehow changes what it is you are doing.
I am resistant because I respect the people that actually tune shocks as a job professionally. By no means what I am doing is what they do. I am just experimenting. Worst case I learn something from a shock that I’m not gonna use anyway.
That's all fine. But you are tuning.
Well changing engine oil is tuning I guess? Again I have not tried this or even seen what will happen. It’s an experiment. Who knows? It may fail?

According to your definition, changing engine oil from 10w30 to 5w30 is modding the engine.
If you live in a colder climate a lot of vehicles recommend different oil for the engine depending on temps.
