For those who are picky about their fluids, what fluid do you recommend?
I plan to perform this DIY with my Motive 'Black' European bleeder.

While i obviously do not race my CTT, i still want a high performance fluid.
Only other prerequisite is to have something highly compatible with winter temps down to -30 degrees.
Yes, i live in Minnesota....the new antarctica.

The fluids that have caught my eye:

1) Endless RF 650
2) Castrol SRF
3) Motul (not sure which version)
4) ATE Gold Type 200

The best performer, good down to -40 is Endless RF 650.
However, its also the most expensive.
Best price i've found is $45 shipped for .5 liters.
The procedure takes a full 1 liters from what i've read.

Appreciate any advice. Thanks!

Well I use endless in my rs. Good stuff. Totally not needed for a cayenne. Motul 600 or ate 200 will be fine and a lot cheaper.

Unless you are racing, the ATE Gold is more than good enough.

ATE 200 is great, especially for a street car.

Sure appreciate the help guys! Thanks.

what they ^^^ said. TIme is a consideration also. In general I do it every 2yrs.

BlazinPond

Got it. Thanks kosmo.
I'm right at 2 years and 30k miles since the last flush, so i am due now!

Any Minnesota/Canada Cayenne owners with cold weather input?
Last call...

I use ATE, it works just fine in Northern Vermont where it often gets to -15F during the winter.

hows the humidity up there? Water is your enemy

I could be wrong on this, but my understand is that racing fluids (like Motul RBF660 for example) actually need to be flushed MORE frequently as they are more hygroscopic than a standard brake fluid.

I use a racing fluid in my Cayman, which sees a fair amount of track use, but I do a full flush every 6 months (and bleed occasionally on top of that). Two years on that type of fluid would be far too long. The advantage of racing fluid is much higher boiling point, but is that really necessary for street use on an SUV? I wouldn't think you'd ever get the brakes anywhere near that range of temps. It's the repeated threshold braking lap after lap that gets them up there.

My bias would be to use the Porsche recommended stuff for the Cayenne. It may boil at a lower temp (which isn't a factor in street use), but will last longer. The higher price for performance fluid provides advantage for something you don't need (boiling point) but disadvantage for something you do need (long lasting).

Found a good article to your point...
They indicated that Motul will require more frequent changes as opposed to a higher grade fluid such as Endless which requires less frequent changes.

"We have also found for the average track customer, the higher the grade of brake fluid, the less frequently they have to do brake bleeds (take Motul 600 vs Endless….Motul you will do more frequent brake bleeds and flushes, with Endless, less). Those who use Endless can do more track days between flushes."

I have ordered ATE brake fluid.
What is the downside to going ATE Super Blue?
Yes, it is hard to get and cost a bit more. Other than that, the specs are identical to the gold version.
I like the idea of alternating the color.

Since the ATE Blue is for 'off-road only' is there any consequence in purchasing?
I suppose the brake police will be after me

I think blue is the same as gold, except a different colour to help you see when all the old fluid is flushed when you are doing a change.

BlazinPond

Exactly the same specs, minus the color. That's why i ordered it.

The Blue is labeled 'for off road use only' and costs more.
But evidently, its still legal to sell as long as the label says the above.

So strange...
Govt. regulation at its finest.

I never liked the blue since it stained anything that was clear plastic. Always thought it was easy enough to flush with just the clear ATE fluid.
