I don't touch it. Never had a problem with any C5 or C6 clutch until the engine blew in my C6Z. While the engine was out I had them install a remote bleeder. Everything was fine for 18 months after the engine was replaced and then I decided to flush the brake fluid. After that the clutch would drop to the floor after a couple of laps around the track and I would have pull it up with my foot to get it to work for the rest of the day. 15 years without changing or flushing the fluid with no issue at all and then 3 years of fighting with the clutch pedal each track day.

My current car was built in June 15 and was delivered to me on 11/30/15 and has 4500 miles on it as of today. Haven't touched the fluid and the clutch is behaving nicely. Yes, the fluid is black. However, black doesn't necessarily mean it is bad.

Black is good!

 

I just found Super DOT 4 on Amazon.

 

Thanks for the correction.

I have a couple of them and should have taken the time to have looked at one before posting, instead of relying on my memory for the exact product name.

 

I am sure glad for this thread. I had never bothered to look at my clutch fluid since taking possession of it on June 13. There are no leaks on my garage floor and I figured everything must be hunky-dory.

Because of this thread I thought it would be interesting to see how dirty the fluid was. Last night I moseyed over to the shed where I park the Vette and opened up the clutch reservoir. Not only is the fluid pitch black and ugly but it's also below the Min level. In fact it's as low as it could get and still have any fluid at all in the reservoir. So low that I'm not going to drive it until I get some fluid. Presumably the mechanic who did the pre-delivery inspection didn't bother to check it either.

I ordered a couple of .25 liter bottles of Pentosin Super Dot 4 brake fluid:

and a Hopkins MixMizer syringe:

Walmart is cheaper for the syringe but I didn't have to go there.
The brake fluid is cheaper by the liter, but I figure the liter bottle is more likely to make a mess from pouring.

Thanks to everybody who provided the good info here:
08G8V8 for the info on the fluid and the .25l bottle.
JoesC5 for the info on the syringe and
kaplana08 for starting the thread


And the moral of the story is that if you haven't checked your clutch fluid, lately or ever, trot out to the Vette and do it.

I guess it's time to check the lube level in the diff now too.
