Yes.
I will eventually use it in place of the 80W gear oil I have in the air chamber in my fork too. But that's still only just about 6ml.

I watched the sr Suntour TriAir oil change video that you posted. Is that service in the video what you want to perform on your shock? My reason for asking, is I see in oil used in the video is 5WT. Where is there 80wt oil being used?

No, not the entire oil change. Just lubing the seals in the air chamber.
80W is what I have in the Epicon fork. Different story.

Then if all you are using Fox Fluid for lubing seals, then that 8 ounce container should last you a long time. Even if you choose to replace your 80 wt fork oil (6 ml), it should last a while. That bottle will last me about 5 or 6 years, maybe a little more.

Float Fluid is not "Flammable". If you look at the flashpoint in the SDS you will see it is 170c (338f) degrees, this makes it a combustible...like most other oils. You would have to heat the oil to 338º before an ignitions source (spark, match, whatever) could ignite it.

Flammable and combustible are the same thing.

To sum my eperience up, this stuff is mostly not suitable for shocks. It's too runny.
I mean it worked and lasted some 300km+ or something and the inside of the shock was not dry, but I didn't like it, and ended up buying the greenish goo from Rockshox, Dynamic Seal Grease or something.

The biggest PITA with FLOAT fluid and the amounts suggested is where it goes.
If your shock is mounted with the air-valve up then it all ends up down in your negative chamber. Making it perform worse.
If your shock is mounted with the air-valve down then it all ends up in your shock pump next time you connect it. Eating the pump hose from the inside out.

I only use grease. Slickoleum does great providing the lubrication film required and it stays where it's needed.

How much do you use? Do you just coat the entire inside of the air can or air chambers with it?

Now that I completely moved from Suntour to Rockshox, AND the fact that the Maxima Plush Dynamic Heavy oil is still not available in any eshop in the EU, I wonder if the viscosity is comparable to the Float Fluid so that I can use it in the air chamber of the fork while I wait for the RS stuff to show up somewhere.
Of course the other alternative is to just slap a bit of SRAM butter in there and call it a day, but I like to do things properly.

Putting oil in the air chamber on a fork is horrible. It turns the grease into sludge, and most of it migrates down into the negative chamber. In my case I had sludge even inside the air shaft, it found its way inside there even through those tiny transfer ports.
You don't need anything else other than SRAM butter.

I guess you know better than the manufacturer, eh?...

Nope, just sharing my personal experience. Others on this forum will tell you the same. (BTW just because a manufacturer does something a certain way or says how to do something, that doesn't mean it's correct. Especially true with RS...)
Personally I've seen zero upsides to putting oil in the air chamber. The fork didn't feel any smoother. It simply created a huge, unnecessary mess. You're free to do as you please of course. Good luck! 👍

I used to use 80W and the Float Fluid in the chamber of two Suntour forks and never noticed anything seeping below the piston even after several months, so while I am not saying it couldn't have happened to others, maybe it's fairly uncommon?
I just believe the manufacturer should know what are they saying, considering significant amount of time was most likely spent on testing a fork before it goes to production.

Just look at what RS does with their air springs and dampers. They're changing and fixing stuff constantly. Some years bladders are superior to IFPs, some years IFPs are superior to bladders. Charger 2 comes out, then shortly after that Charger 2.1 comes out. They release an air spring where the seal had leaks air into the lowers, then they come out with a redesigned seal head, then they come out with another seal head that's completely different again, then they copy Vorsprung with their new air spring. Why should I trust that they know what they're saying?

RS only started suggesting adding oil to the air chamber recently. I highly doubt that the sludge leaking down is uncommon. Just think about it, you have a transfer port between the positive and negative.
But again, feel free to try adding oil, and make sure to report back after your next air spring service. 🙃
