Pentosin states that 202 is just fine to be mixed with 11S, but not the older CHF 7.1 for those that are curious. C6s should all have either 11S or 202 in them already depending on the year.

The method that I used, suck it out of the reservoir with a pastry baister, refill with clean fluid, run the engine for a few seconds while turning the steering wheel lock to lock. Keep doing this until the fluid is clean. I ran 3 Litres through it to flush it and get it really clear.

Or you can.
Empty the reservoir tank and remove the return pipe. fit a peice of pipe to the reservoir return connection and seal it off.connect a legth of pipe to the return pipe and feed it out through the wheel arch through a clear section of pipe and secure it in a large (4ltr) container. This now takes two people. One observes the reservoir with the lid off and one starts the engine then slops it when the observer calls low fluid in the reservoir.
Fill the reservoir to the top and restart the engine but rapidly go to full lock, stop when low. Refill start and go to the other lock, stop fill start and centralise the steering, refill and observe the colour of the fluid for clarity. You may have used a litre by now.
Run the engine again and stop when low. The fluid should be clean and you will have used about 1.25 litres.
Replace the pipe work secure the clip and fill the reservoir to the Minimum and run the engine for a couple of minutes. Top up to the correct level, test drive the car then check the level again. And of course use the correct fluid. Job Done.

The actual system is 0.85 liters.

First attempt was to do a DIY - use the mityvac to suck the fluid of the reservior; but there is the damn filter in the reservoir which prevents you from putting the tube down to suck it off. The return pipe wouldn't come off (I was afraid of fluid spilling everywhere, so I didn't apply to much force).

Took it to an indy and he did the first method mentioned by roy; fill the reservior while one person turning the steering side to side and the other pouring sucking the liquid out. He used about 1.6liters of the Pentosin 11S.
