I boil it over too much at the track in the 996 (PF01 pads with RSR front scoops and GT2 rear scoops) with 600, so I run Motul 660 or Castrol SRF all the time.

I run RBF600 in all my cars, track & daily driver.

Yes, because it's a race fluid and it isn't designed to be used for 2 year intervals like a regular brake fluid.

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.

Gonna do a brake fluid flush using the Motive Black Label power bleeder I just got. Don't know if my car has ever been flushed. Yikes!
Motul 600 seems to get good reviews on the threads I looked up, and Castrol SRF is just too expensive for me. I plan on tracking the car only occasionally, but this is primarily my daily driver.
Any downsides to running Motul RBF 600 on a DD? I also see RBF 660 and Dot 5.1. What do you recommend?
TIA.
The Motul is just a wee bit better than ATE. I had a table around here somewhere showing price per oz and wet boiling point.
The funny thing is, unless you're a track fanatic flushing fluid more than once a year, SRF is actually a good deal given it's insane wet b.p. Pay once, never change it.
just in case you needed one more person to tell you this...Yes you'll be fine with Motul 600 on the street. May not see the benefits of it as much but if you intend on doing a track day here or there it's nice insurance to have in the car for the little extra up front.

Cool, thanks for the input guys.
Someone said I need to change it every year. Is there something unique about the Motul that mandates this? Won't a 2yr flush cycle (unless I track it) be sufficient?
Yes, because it's a race fluid and it isn't designed to be used for 2 year intervals like a regular brake fluid.
If you want to do Motul, use Motul 5.1. I have had very good luck with ATE Typ 200.
I wouldn't use RBF600 in a street car.

Motul 600/660 is fine for street/track use. On the street, it is more expensive than OEM or ATE, or other generic DOT 5.1 that will work just fine. But, depending on your track, tires, pads, and style, the cheap stuff might work. But if you are running R-comps with PFC pads, you should be using Motul or SRF.
And for serious track use, SRF can definitely be more cost effective. Just bleed the calipers before every event and you're golden. With Motul, you should probably flush every 6 months due to moisture getting into the system. Also, be sure to top off your opened cans of brake fluid with nitrogen or other HTA gas to eliminate condensation in the bottle.

Interesting. Thanks 'himself'.
If that's the case, I might get the half-the-cost Motul 5.1. When I track the car, I'll either leave it in and see how it does or flush to Motul 600.
Does Motul 5.1 have the same "super hydroscopic" properties that the Motul 600 apparently has? Will I have to flush every year with the 5.1 like I would have to with the 600?
I used Motul 5.1 in my R32 and it was quite good. Slightly higher wet boiling point than a regular DOT 4 fluid.
You can use the 5.1 for two years and then flush it.
Motul 600 is completely fine for daily use. I run Motul 600 in 2 of my cars. I boil it over too much at the track in the 996 (PF01 pads with RSR front scoops and GT2 rear scoops) with 600, so I run Motul 660 or Castrol SRF all the time. SRF and 660 have the same dry boiling point. SRF has a much higher wet boiling point. 660 is about $10 more a bottle than 600. Remember than a bottle of SRF is twice the size of a bottle of Motul, so when you compare the cost of a bottle of SRF to 2 bottles of 660 it is not much more.
And, as I have respectfully said in the past, if you are boiling Motul 600 regularly at TWS, MSR, etc. in your 996 Carrera, you are braking wrong. Get some instruction on proper braking on track, and you should never boil 600, ever.
Hell, I used to run Super Blue with PFC01's all the way around, and never once boiled it, even in 100 degree weather. Now I use 600 with PFC06's, and it is wonderful.
And I drive a LOT faster than you.
