Before I change the clutch fluid - is this the right stuff?
Went to the local auto parts store...they didnt have the same stuff as in the video - so is this the same stuff? DOT4

Should work, but don't you have a Walmart closer then an auto parts store. I purchase my Prestone DOT 4 brake fluid there at less then $3 a bottle, and I'm in a Walmart more often then I'm in an auto parts store.

Take a look at this StopTech White Paper on brake fluids - you'll learn everything you ever wanted to know about them!!
Click for StopTech White Paper: Brake Fluid 1A
In there you can read:
So virtually all DOT 4 fluids are going to be very similar - except, as they mention, Castrol SRF is in a whole different league all by itself.
I use Motul RBF 600 in the brake system, but just run Prestone DOT 4 in the clutch and have had no problems during hard running on the track.
Here's a link to the list of other White Papers that have info on EVERYTHING about brakes (calipers, pads, how to bed pads, etc., etc., etc:

In there you can read:
.....the US Government’s Specification for brake fluids – will tell us all we need to know…
.....However, the brake fluid industry has by consensus decreed that glycol ether fluids are the most economical way to meet the requirements, so there you are.

"Besides boiling points, what else does FMVSS116 specify?
While the performance enthusiast is most concerned about boiling points, the government holds no less than fourteen properties of brake fluid in the highest regard. Fail just one of the tests, and the product cannot be legally offered for sale in the US. In order of listing, the properties under the spotlight include:
1. Dry boiling point
2. Wet boiling point
3. Kinematic viscosity (how thick the fluid is, with lower generally considered better for flow)
4. pH value (measure of acidity, with higher generally considered better for corrosion resistance)
5. Chemical stability
6. Corrosion
7. Fluidity and appearance at low temperature
8. Evaporation
9. Water tolerance
10. Compatibility
11. Resistance to oxidation
12. Effects on rubber
13. Stroking properties (lubrication capability)
14. Fluid color"

Point made!!
DOT 3 is DOT 3, DOT 4 is DOT 4, etc.
If the manufacturer puts it on the container, the stuff must meet the spec!

There are a few good DOT-4 Brake fluids to choose from. I have been using Motul RBF 600 Racing Brake Fluid.
http://www.amazon.com/Motul-RBF-Raci.../dp/B000AURZ08
Description from the manufacturer:
Motul® RBF 600 has a very high dry boiling point of 593°F (311°C) and a wet boiling point of 420°F (215°C).
100% synthetic fluid for hydraulic-actuated brake and clutch systems. Specifically designed to resist the high temperatures of actuated (steel or carbon) racing brakes and clutch systems.

Here's a picture of a can of the GM stuff:
You can see that it says that it's for both the brake and the clutch systems. The same type of hydraulic fluid is used in both systems.
Most "brake" fluid containers aren't going to also say "clutch" on them, because they don't need to - if you have a hydraulic clutch, it's just an established fact that "brake" fluid is the stuff you use in it.
So.....a hydraulic clutch uses "brake" fluid!!
And.....I certainly wouldn't get hung-up on thinking that because it says "GM" on the container that it's any better than any other stuff - we don't know who has the current contract to bottle their stuff up for GM.

I said in the above post:
However....I came across this post in an old thread (there have been about a gazillion on this subject) and clutch fluid guru and my fellow Ranger says it all in this post:
http://forums.corvetteforum.com/1571614234-post18.html
You can see he seems to have found out who bottles up the GM stuff:
Like Ranger says, the Prestone DOT 4 has essentially the same specs as required by a DOT 5.1 fluid (which is what Super DOT 4, or DOT 4 Plus, is).
