I can confirm GPR6 2.5 works perfectly. I've been having issues with the rear M7120 on my Rail. Swapped out to this last week, ran it for several rides in 0-6 degree C temperatures and the pumping up has vanished. It's rock solid. So good I've bled the front with it as well.
The GPR is extremely thin at all temperatures, close to redline likewater. As a quick and dirty test I placed both Putoline and Shimano fluid in the freezer over night, then filled the same 20ml syringe with each fluid. Shimano took 52 seconds to drain and the GPR6 took 17 seconds. Pretty much speaks for itself.
Yes its a fully synthetic, no it won't destroy the shimano seals. Rear shocks and forks are full of them....
