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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ How about: "Reliable Racing Brake Fluid for Consistent Performance on My ZX-6R *by K***S on 8 May 2026* Absolutely!
