Review: The Best Since Slice Bread 🍞 - Being the owner of 2013 F150 3.5L Ecoboost with a 2 inch suspension lift upgrade with IVD Struts, 35x12.50r18 inch tires, Rear Nitro Shock Absorbers, and etcetera. You will need the best of the best DOT 4 Brake Fluid for vehicles in the weight range of 7200 pounds. The braking power of this Motul 660 is unparalleled to the standard stock DOT 4 brake fluid from your local auto parts store, heck any standard regular brake fluid pales in comparison to Motul 660. It's not overkill by any stretch of the imagination. Pay the extra dollars for high performance brake fluid and know you're in good hands. It shines even better in the winter snow storm with icy roads. I've recently used Motul 660 in my parent's 2018 Toyota Highlander 3.5L XLE and the braking experience was night and day plus the factory stock brake fluid was at 80,500 miles of usage so believe me when I say "it was darker than night". So yeah. Enjoy 😉 Cheers 🍻 Review: Great upgrade for brake fluid - Great quality product. I drained out and replaced the brake fluid on my 2017 R6 with the Motul RBF660 fluid. Made sure to flush front and rear lines and fill them completely with the Motul brake fluid. Temp range on the fluid is great and it gives me confidence I can brake hard and not have to worry about my fluid failing. ## Features - For hydraulic actuated brake and clutch systems - Non silicone synthetic fluid - Extreme thermal resistance and stability - Very high boiling point (325 degree centigrade / 617 degree Fahrenheit) - Better aerodynamic performance - Fit type: Universal Fit ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005UGKKW2 | | Best Sellers Rank | #76,851 in Automotive ( See Top 100 in Automotive ) #44 in Hydraulic Oils #46 in Brake Fluids | | Brand | Motul | | Brand Name | Motul | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 583 Reviews | | Flash Point | 325 °C | | Global Trade Identification Number | 00182682992405, 03374650020501 | | Included Components | Motul 101667 RBF 660 Dot-4 Racing Brake Fluid 500 mL | | Item Form | Liquid | | Item Type Name | Motul 101667 RBF 660 Dot-4 Racing Brake Fluid 500 mL | | Item Weight | 16 ounces | | Liquid Volume | 500 ml | | Manufacturer | Motul | | Material | Silicone | | Model Number | 101667 | | Number of Items | 1 | | Number of Packs | 1 | | Package Information | Bottle | | Part Number | FBA_847205 | | Recommended Uses For Product | Brake oil | | Specific Uses For Product | Racing | | UPC | 182682992405 | | Unit Count | 16.9 Fluid Ounces | | Upper Temperature Rating | 328 °C | | Warranty Description | Motul 101667 RBF 660 Dot-4 Racing Brake Fluid 500 mL | ## Product Details - **Brand:** Motul - **Item Weight:** 16 ounces - **Liquid Volume:** 500 ml - **Material:** Silicone - **Package Information:** Bottle ## Images ![RBF 660 Factory Line Dot-4 100 Percent Synthetic Racing Brake Fluid 500ml (101667) - Image 1](https://m.media-amazon.com/images/I/71gfePutajL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What is the difference in performance between motul rbf 600 vs. rbf 660?** A: The boiling temp is higher on the 660 **Q: is this a low viscosity type brake fluid, for example type can be used in 2015 mini cooper S ?** A: This brake fluid is intended for use where vehicles will be used in more extreme conditions like road racing or high performance driver education. It isn't really practical for street use because of its high cost. I use it in my Porsche Boxster and used it in my Pontiac GTO. If you are planning to track your car (use your car on a road course) this fluid will help prevent brake overheating and fade. **Q: Is this 12x 500mL bottles?** A: NO. It is one bottle. The Amazon title is wrong. **Q: Is motul still using euro date on the bottles, i just received my order and the date is 20/12/17, which i think is past the expiration?** A: Brake fluid doesn't "expire". It will absorb moisture. But as long as your bottle was sealed, you will be fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Best Since Slice Bread 🍞 *by M***L on May 14, 2024* Being the owner of 2013 F150 3.5L Ecoboost with a 2 inch suspension lift upgrade with IVD Struts, 35x12.50r18 inch tires, Rear Nitro Shock Absorbers, and etcetera.

I drained out and replaced the brake fluid on my 2017 R6 with the Motul RBF660 fluid. Made sure to flush front and rear lines and fill them completely with the Motul brake fluid. Temp range on the fluid is great and it gives me confidence I can brake hard and not have to worry about my fluid failing. ### ⭐⭐⭐⭐⭐ Been using Motul brake fluid in all my cars *by M***O on January 3, 2025* Motul makes higher boiling point brake fluids (racing) and any hard driving scenarios possibly like mountain driving that can tax the rotors and calipers with excessive heat. When i replace my fluid with these, it might be in my mind but the pedal feels a little better so i do replace every time i do my brake pads. Great stuff. ## Frequently Bought Together - Motul RBF 660 Factory Line Dot-4 100 Percent Synthetic Racing Brake Fluid 500ml (101667) - K&N Motorcycle Oil Filter: High Performance, Premium, Designed to be used with Synthetic or Conventional Oils: Fits Select Honda, Kawasaki, Polaris, Yamaha Vehicles, KN-303 - Motul 104121 300V Factory Line 4T 10W-40 100% Synthetic Engine Oil 4 Liters Ester Core Technology Racing Motorcycle Motor Lubricant --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/17354955-rbf-660-factory-line-dot-4-100-percent-synthetic-racing](https://www.desertcart.jp/products/17354955-rbf-660-factory-line-dot-4-100-percent-synthetic-racing) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-26*
