## Questions & Answers

**Q: Will it mix with the non synthetic fluid?**
A: According to the Motul documentation: "Avoid mixing with polyglycols based brake fluid with lower performances. Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM)."

**Q: Can you use this on 04 subaru wrx as the amazon fitment is saying no?**
A: All Brake Fluid, including Motul 660, is a universal fluid that can be used in any motor vehicle's hydraulic brake system, including a Subaru WRX. However, Motul 660 is a much more expensive high temperature brake fluid designed for racing car applications on the race track where the brakes can glow red hot and regular specification brake fluid would boil and the brakes would fade. Unless you are racing your car or using the brakes really hard in repeated applications, you will not need such a higher specification and cost brake fluid like Motul 660.

**Q: Is it normal that its a little darker (darker shade of yellow)? Just used it to flush and replace oil fluid**
A: It will be darker when you flush brake system as it is mixing with the old brake fluid during the system bleed process.

**Q: What is the date format printed on the bottle and is this a manufacturing date or expiration date?**
A: Hi Robby,
Usually for the oil there is no expiration unless it is having contact with the air. As the brake fluid is hydroscopic, if you keep the bottle in cool, dry well ventilated place it should be good for a few years. The date is manufacturing date printed. Motul can answer better about it.
Regards.

*by S***M on January 10, 2024*

I replaced the OE brake fluid in my Kia Stinger with the Motul RBF 660. It's probably mainly made for the track, but I'm using it on the street. The OE brake fluid quickly boiled, so I needed something with a higher boiling point.
