The topic regarding which brake fluid to use (Motul, SRF, Torque, Endless, etc) has been beaten to death, but nowhere have I been able to find a discussion on Porsche Classic Brake Fluid.

Suggestion
In other words, if the car currently has gold brake fluid, I'll use the Ate Blue for the flush.

I'm taking a wild guess Porsche simply switched to using LV fluid with the 997.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

It worked great in the vintage cars with drum brakes and no brake cooling..

The "Classic" brake fluid is recommended for Porsches MY 2004 or older (996 and older). This is a different fluid than the
current
factory brake fluid (997 and newer).

Does anyone have an
y good info about this "Classic" and why I would want to use this for my 04 996 C4S vs the current factory fluid or one of the high performance brands mentioned above?
I was told the ATE Typ 200 is the same as the "Classic" Porsche fluid. I think I will start using it. From what I can see it is a quality product with good technical specs and not overpriced like the popular favorites.
Appreciate the feedback on ATE fluids, but the underlying question is regarding why Porsche recommends a different (i.e. "Classic") brake fluid vs the factory version for 997 and newer vehicles. What's the difference?

whats the big deal. If you are flushing every 2 years, a few drops of old ate gold won't cause any issues, so the advantage of the blue is pretty much pointless
I agree that there's nothing magical about the blue fluid. I alternate between gold and blue on brake flushes because it makes it easier to see when the new fluid has reached the farthest caliper. In other words, if the car currently has gold brake fluid, I'll use the Ate Blue for the flush. When you're bleeding you can see the fluid turning from gold to blue.
If its still available,, the heavy truck division of ford used to sell a product for their large juice
brake trucks that came in a Ford Blue can and was suspiciously the same color as the ATE
only it was cheap at the time,, like 25 a gallon,, IIRC it only came in 1 and 5 gallon cans. ..
It worked great in the vintage cars with drum brakes and no brake cooling..
So the new Porsche brake fluid is dot4 LV. LV viscosity is better for ABS and traction control stuff. At least that's what the internet says. The older is not LV.
Thank you for trying to answer the question. This thread somehow got hijacked into the blue stuff.
I question that theory though because the 996 C4S has PSM and ABS.
Someone at another forum mentioned different seal material.
Nothing to do with seals. I don't know when Porsche made the switch to LV and why they back dated it only until 2004. But 3-4 years ago Porsche did not use LV fluid. My BMW did, and when I did brake flushes before for the Porsche's I needed different fluid. I just noticed recently the Porsche bottle of fluid said LV
Any dot 4 will work but the LV works better at low temps.
944 & 928 had ABS in the 80's, this isn't exactly new technology.
Looking at a couple of sites, the newest models listed for the classic brake fluid are CGT and 996. I'm taking a wild guess Porsche simply switched to using LV fluid with the 997.
Other manufacturers (like Saab & BMW) switched around 2002, the cars did not change.
This is just Porsche offering what was factory filled when the car was made, good old DOT 4. Every publication I've seen says LV is backwards compatible in any car where DOT 4 is specified.
Porsche knows people will spend money on anything classic specific so why not brake fluid? If they thought they could get away with selling classic blinker fluid, they would sell that too.
It may just be, as you say, they are offering what was offered at the time. Although keep in mind the Classic fluid is actually cheaper than the current.
