All Castrol SRF the same?
I was shopping for SRF and I have seen some good deals for the stuff that comes in the metal cans. Like this:
This may sound like a dumb question but is there any difference between that and this: I wanna get the right stuff. Thanks!

Motul 600 is a pretty good option. The only bad part is once it boil it you have to bleed it. SRF will come back and last a lot longer. Other than that, I've never noticed a difference.
From a cost standpoint, I'd go with Motul 600 if you do your own bleeding and SRF if you pay someone. I wanna say that I get twice the life out of SRF...so you come out even on the cost of the fluid but you save on paying someone to bleed your brakes. Yes, keep it away from your oil...don't wanna make a mistake.

I want something that I can run a little longer (less hygroscopic than other racing fluids) and that will come back from a boil. From what I have read, SRF is the way to go.

I'm not sure if its less hygroscopic but will come back. I think SRF is the way to go for you.

I read in another thread that it was less hygroscopic than other racing fluids (but still more so than the OEM stuff). I don't know if there is any truth to that though...

I am running Project Mu G-four brake fluid. Works good. Higher dry and wet boiling points than SRF and less moisture absorption for street driven cars.
Motul 600 is good for the budget but less heat tolerance than the Project Mu or SRF and it needs more frequent flushing. |

This thread sums it up nicely. http://forums.bimmerforums.com/forum...&highlight=srf Basically, you don't need to change the fluid out nearly as much as Motul. It doesn't absorb as much moisture as other fluids so it's boiling point stays high. And you can mix it with regular brake fluids. .

Castrol SRF dry is 310 and wet is 270. http://www.castrol.com/liveassets/bp...s/SRF_B768.pdf It's the wet boiling point that really matters since that's what will affect your pedal feel. Mu is a little cheaper. It's too bad LeMans_Blue isn't here anymore. He'd give a NICE summary about brake fluid. .

Not sure...I remember reading that its just as hygroscopic but the wet boiling point is better. Who cares...it just works!

Why? Never heard that. I know DOT5 is incompatible. But you can mix DOT 3 and 4. I believe Castrol is DOT4. So how does it work when you initially bleed the SRF into the brake system that has non-SRF fluid? Some of the old fluid will mix.

You can top off with any Dot 3 or 4. Just reduces the benefit of using SRF. True, I top off with SRF unless it forces me to open a $75 bottle just to use a wee little bit. That's when I just use some Motul600 or regular ATE.

AP was on here a long time ago saying their fluid recovers better than SRF once boiled.
Sounds like Berk was cooking the brakes each time out. I would think most weekend track event drivers won't be cooking the fluid each session, or any session for that matter. I just like the flush it once and forget about it for a year concept.
