If you're boiling the clutch fluid, you're obviously driving it hard enough that you should be taking into account certain OEM components that may not hold up under the aggressive conditions. So you should be considering higher temp fluid BEFORE any of the clutch hydraulics start failing. Brake fluid is another example - Car & Driver gave the Z terrible ratings because they took a stock Z and drove it hard on the track with stock fluids and the brake fluid boiled and they crashed ... idiots.

The TSB is bull$hit; fluid is not causing CMC or CSC issues. If fluid were the cause, all failures would be under hard driving or at least hot temp driving. But a CSC on a Z with less than 1000 miles failing in the dealer parking lot is due to shitty parts, not the fluid.
