Recommended brake fluid for the Tesla Model 3 Performance with PUP

[RKDauto]

What brake fluid is recommended for the OEM brakes for both the street and track? For street driving, the brake fluid is adequate, but I heard the OEM brake fluid quickly becomes a liability at the track.

I had great experiences with ATE TYP DOT4 racing fluid in my ICE track cars. Will most likely go with ATE when the time comes to upgrade to SS brake line and BBK on my 3 since I have a stockpile of them. When I'm out of ATE, I plan to try Motul 600 or 660.

Good: Motul 600
Better: Motul 660
Best: Castrol SRF

Also works for that list. The Castrol cost me $60 for a 1L bottle. The Motul comes in 500ml bottles and 660 can be had for about $20 each, so only about $40 for the L you'll need for a full flush.

I did the Motul 600 because that's what the shop installing my brake lines had. May upgrade to SRF later if this isn't sufficient.

I've BOILED both Motul versions on track, but never SRF.

SRF is absolutely worth the extra $$, IMO.

SRF's big trick is that its wet boiling point, the boiling point after it's been contaminated by moisture (from the air), is nearly the same as its initial (dry) boiling point. Motul 660's dry boiling point is actually slightly higher than SRF's but the wet boiling point is about 65C (120F) lower.

I expect both of them dry are more than the Model 3's stock disks would survive (and I don't have $1K to drop on replacement front disks). However living in a high humidity area SRF seemed the way to go, for the longterm.

You are correct. Castrol SRF is expensive, but you don't have to bleed as often because of the high wet boiling point. I've personally used them on my previous F80 M3, 991.2 GT3, and GT4. Firm pedal feel and doesn't require light bleeding after each track day.

Love the Castrol SRF. However I typically bleed out and replace the brake fluid before each track event, which makes Motul far more economical. In such case, wet boiling point isn't a major factor.
