I believe that what your saying is true if all you did was replace the fluid however the pumping of the clutch 30 times and then changing the fluid again and again...until clear is essentially clearing out all the fluid especially if done on a regular basis....


-1
Change the fluid in the clutch master cylinder reservoir.
(a) Draw out the discolored fluid with a syringe, keeping the corrosive fluid off your paint.
(b) Wipe down the reservoir and the diaphragm on the cap, using a clean, lint-free towel.
(c) Locate the fill-line in or on the reservoir.
(d) Refill the reservoir to just below the fill-line with fresh fluid specified in your owner’s manual. Do not over-fill. If the reservoir has both minimum and maximum marks, suggest filling to the midpoint.
(e) Clean the diaphragm if dirty and properly seat it on the reservoir cap.
(f) Replace the reservoir cap snugly.

-2
With the engine off, pump the clutch pedal full-top to full-bottom to full-top 30 times. This action causes fluid in the clutch hydraulics to circulate, blending the new and old fluid, and revealing the color of the blend. It also helps scour residue from the actuator (slave) and displace upward into the reservoir any air trapped in the hydraulics.

-3
Then, re-inspect the blended fluid in the reservoir. If it is totally clear and shows zero murkiness, you are finished. If it's not, restart at (2). Continue to change the fluid as many times as needed, with the full, slow top-to-bottom-to-top pedal pumps between changes, until it remains absolutely clear and clean. Getting the fluid clean the first time is the hard part.

-4
Next come the easy part, keeping it clean. Re-inspect the clutch fluid each time you add gasoline or prepare for spirited driving, including the track. If it is not still clear and clean, restart at Step-2. Usually will take only two or three swaps to get the fluid pristine again.
