## Questions & Answers

**Q: £26 for one litre? That cant be right. Why is this oil so expensive?**
A: Think you can get it for £18 if you want to wait a week for delivery.   If your a prime member £26 you'd get it next day. 
Depends if you valve your time and a journey to your local motorbike shop I suppose.

**Q: It's ok for bmw 320d from2012?**
A: It’s suitable for any vehicle but you shouldn’t mix the fluids. If you’re using this you should ensure you’re flushing the system fully. 
Just so you know this is a higher spec fluid (higher boiling point) and it will be a waste of money unless you’re tracking the car.

**Q: What's the viscosity at -40°c°f? looking for 750 cst or 750 mm²/s to help brake esp system.**
A: Not this it’s racing fluid  high temp

**Q: Can you use this for Road bike use**
A: Hello,I confirm that you can use this oil to drive on the road.It is a high quality oil.Thank youSPO moto scooter

### ⭐⭐⭐⭐⭐ Best brake fluid on the market

This is the best brake fluid you can buy no more boiling the brake fluid can't recommend this enough!

### ⭐⭐⭐⭐⭐ Cheap performance upgrade you can really feel.
*by J***N on 3 May 2020*

Forget intakes and power etc, if your going to be tracking your car the best thing you can do is get a set of braided brake lines and this brake fluid. Im running a fiesta ST180 on OEM pads and discs and the difference the lines and fluid made were crazy. Full day at Caldwell park and I didn't have brake fade once. Confidence in the pedal let me push harder and harder.
