any DOT 4 fluid will do, but given that you have a nice BBK, I would at least use Penrite Racing RBF600 or Motul RBF600 fluid and change it every 6 months.

oops, sorry I mistakenly read ongti's signature as richmurphy's... any dot 4 is fine, penrite super dot 4 is prob better.

Got some ATE SL.6 from HSY today. Quite a bargain i thought at $12.50 for 1l. Thanks all for your assistance.

So I've just ordered ATE SL.6 from HSY today for my Passat B7 V6 4Motion Highline as VW also specifies the need for VW Standard 501.14 brake fluid in my car. Ordering from HSY was very easy and they were very helpful. So thanks to HSY.
And thanks for the info

HSY will sell you ATE

Initially, it was somewhat of a challenge finding a suitable non OEM fluid. And at the end of the day I'm not sure it's actually going to make much of a difference. The boiling points of the VW OEM fluid are dry 265°C / wet 170°C. The ATE SL.6 is dry 265°C / wet 175°C.

In my search for information though I found these threads that others might also find interesting:
- Car and image Forum
- Jaguar Forums

It seems the primary difference with the VW standard is the need for a low kinematic viscosity at -40°C of <750 or <700 cST. This seems to be the ISO 4925 Class 6 standard. Many DOT 4 fluids only meet the ISO4295 standard or other classes. Although I haven't been able to find a reference to the standard to find out the specifics.

I'm not sure how much of a difference this will make in Australia. Perhaps if you live in the cooler regions where we get sub 0°C temps it might benefit your ABS system over a higher viscosity fluid. Considering we're talking about a system that can be responsible for saving our life though, I'm not sure I want to risk the use of a product that doesn't meet this spec.

So it seems some other brake fluids that meet this VW spec are (links to manufacturer info where possible):

• VW OEM brake fluid (from dealer, VW/Audi/Sloda Part#:B000750M3)
• Land Rover RRS D3 (from dealer?)
• ATE SL.6 (from HSY)
• Pentosin DOT 4 LV (from Liquid Intelligence or Phoenix Lubricants)
• Textar DOT 4 PRO (from Imparts)
• Ford Dot 4 LV High Performance WSS M6C65 (from dealer)
• Shell ESL Super Dot 4 (not available in Aus, can order from OS)
• Castrol React Dot4 Low Temp (not available in Aus, can order from OS)
• Comma Oil DOT 4 ESP (not available in Aus, can order from OS)
• Eurol DOT 4 LV (not available in Aus, can order from OS)
• Liqui Moly SL6 DOT 4 (not available in Aus, can order from OS)
• TRW DOT 4 ESP (not available in Aus, can order from OS)
• TRW 5.1 ESP (not available in Aus, can order from OS)
