How often do you top off the clutch fluid reservoir if at all. I have a 07 Zo6 and noticed it is a tad below the min. mark.
Thanks.

Don't just "top it off", do a complete fluid swap using my fellow Ranger Ranger's procedure:

In that video at the top of the post, after some great info about the clutch and the reasons for clutch fluid getting dirty, at 3:20 into the video he starts the fluid swap procedure.

It only takes a few minutes, and it's very cheap if you use Prestone DOT 4 (I do, and it works great for hard track use in my car - about $3 for a 12oz bottle at Walmart).

I swap fluid about every 3 or 4 months for street driving, and before every track event. I just did it yesterday when putting in new brake pads and bleeding the brakes when prepping the car for a track event Thurs/Fri, and the clutch fluid swap was the quickest and easiest part of prepping the car.

I have never topped mine off. It stays between the min and max mark. I do the ranger method a few times each summer. In fact I just did it yesterday. Doesn't take long at all. Getting the supplies together takes longer than swapping the fluid.

Ranger it when it starts to get dark

I don't top it off. I change the fluid every two years.

My 06 Z51 calls for Super DOT 4 brake fluid for the clutch. The first time I swapped the fluid, I tried to buy the fluid from a Chevy dealer. The local dealer did not carry it. The service department informed me that they use DOT 3. I also tried a local Cadillac dealer because the CTSV at the time required the same clutch fluid. Same responses. Now I use BG Super DOT 4 for the clutch fluid. I will use this product for the brake fluid once the extended warranty expires.

When I called my local dealer about doing a fluid change I was told the same thing. I told the guy the brakes and clutch use two different fluids. He had a "tech" near and asked him. The "tech" said they use the same reservoirs and fluid. I did the ranger method myself and will find a different dealership to do a full drain.

It makes sense to use the same fluid for both brakes and clutch but the one that makes sense is the DOT4 not the DOT3...dumb dealer.

Amazing. GM still does not realize that the conduct of its dealers reflects on the brand. GM's management still sits in the top floors of the tower, clueless to what transpires in the real world.

Caveat emptor.

Dumb and inconsiderate

Wrong resevoir !!

Larry/car

Went to a Chevrolet Dealer near where I work. They didn't know off hand what fluid the clutch took. They did the research and ordered the fluid, I picked it up the next day. The dealer where I purchased the car not only knew, even had it in stock. This will be my second fluid change (2006 with 11,000 miles).

Thanks for the help guys

There's very little difference between DOT 3 and DOT 4 brake fluids. They are also compatible, so you can mix them together. DOT 4 normally has higher boiling points.

So, for a normally street driven car, you're find with DOT 3 in the brakes and clutch. If you do any track or very spirited driving, you have to go to a DOT 4 or even go by boiling points. I use Motul 600 (or something like that) in the brakes, but regurlar DOT4 in the clutch because it's cheaper when you do the Ranger method.

Honestly, being picky over DOT 3/4 if all you do is street driving, you're just splitting hairs.

After reading numerous threads on clutch fluid this seems like the best maintenance method to use. Just change out the fluid in the reservoir every few months and that should prevent problems.
