The GM clutch fluid used to have some additional friction modifiers that were not in regular brake fluid, so I have always just used the GM fluid. I just buy Prestone brake fluid for the brake reservoir.
The clutch reservoir only takes about 2 ounces, so you can get multiple changes from the GM bottle.. I usually just draw the fluid out of the reservoir, and put in new fluid every few months, and drive it... I have never had to go through pumping and multiple changes and the fluid has always stayed clean..

When I had a clutch issue in my C5 and did the ranger method, was admonished by a trusted member of the dealers service department for using non-gm fluid. (Emphasis on trusted, not dealer.)
Apparently, GM fluid has, amongst other additives, graphite, which will darken the fluid over time. Using non-gm fluid or fluid w/o graphite may make the clutch worse, not better.

So are you telling me I should not trust my own parent?
Who has worked in the service department of the same Chevy dealership for almost 40 years, and has more SAE certifications than all the mechanics there combined, including multiple certs on ‘vettes?
I use Motul DOT 5.1 (not DOT 5) for my brake and clutch systems. Works great, and has a high enough boiling point for me. Its glycol based and is fully compatible with all DOT3 and DOT4 fluids also.

Why why would clutch fluid have a friction modifier? This isn't a wet clutch like that on motorcycles. The fluid never even comes into contact with the disc/PP. It's only job is to act via a clutch master cylinder to apply pressure to PP and disengaged the disc.
