Using ATE super blue in your PSD? Yes? No? Use something else?
Hello,
1990 s4 auto
I'm going to change out the PSD fluid, and I've got some ATE Super Blue here. Is this good to use in the PSD, or should I use something else? Thank you.

I use it. I think ATE is quite hygroscopic so don't let it go too long before flushing out. On the other hand, there isn't a need for the high temp characteristics of ATE Super Blue/gold in the PSD so some type that won't suck up water as easily may be better. I think Castrol makes something called LM or similar. LM for low moisture.

Thanks guys - I learnt something new.
Next time I flush the PSD I will change the oil type.
I assume it then can be left longer between flushes - how long?

When Porsche started to use ATE blue it increased the brake fluid change intervall from 2 to 3 years.
Both ATE blue or gold are very good brake fluids. I used both in Germany and I drove my cars pretty hard on the Autobahn.
I'm changing my brake fluid every 3 years no matter what. I'm switching between Gold and Blue every time I flush the system. This allows me to see when the new fluid reached the brake caliper pistons, that's it.

Dennis,
I can't see where there will be much heat added by the PSD pump. The reduction of water in the system is to prevent all those expensive parts from rusting.

Problem with flushing PSD with ATE racing brake fluid (DOT 4) is they only sell it in 1 liter bottles.
Flushing the complete braking system takes almost 1 liter, while the PSD can be flushed with less than one quarter liter. So if you flush them both you'll end up with alot of waste fluid. Once you open a container, the shelf storage life is greatly reduced, and certainly not good to use 3 years later.
I just recently flushed my braking system and PSD after only 3 years. I use the clear/amber ATE type 200. The car is always garaged and even here in Southern California coastal area, flushing the brakes shows a noticable color shift to darker fluid. The darker fluids (with water absorbed) migrate to the calipers, so viewing the the reservoir color is not a good judge.
So, even thought I'm flushing with the same color fluid, it's easy to see when the new fluid starts coming out the bleeder screw.
The only difference between gycol based DOT 3 and DOT 4 is a chemical additive which increases the boiling point temperature. So, nothing wrong with flushing the PSD with DOT 3 fluid.
