DOT 5
If the synthetic fluid is silicone based, yes. If it is a dot 3or 4 type, no.
Some alternatives to mineral oil brake fluid that can be used in vehicles include silicone-based brake fluid, glycol-based brake fluid, and synthetic brake fluid.

yes,,,, all brake fluid is synthetic. EXCEPT Dot 5 which you CANNOT mix only because it is silicone based.
Dot 5
BRAKE FLUID DOT 3 IS WHAT IT CALLS FOR You can use dot 4 also but never dot 5, it is silicone based and will not mix, it is for racing only.
I would say any fluid could act as a coolant. Brake fluid DOT 3, 4 and 5.1 is a polyethylene glycol based fluid. DOT 5 is a silicone based fluid. DOT 3, 4 and 5.1 will absorb water, reduce its boiling point and degrade its performance.
Some alternative options to brake fluid that can be used in a vehicle's braking system include silicone-based brake fluid and mineral oil. These alternatives may have different properties and compatibility with certain brake systems, so it is important to consult with a professional before making a switch.
For a 2012 Harley-Davidson without ABS, you should use DOT 5 brake fluid. This type of fluid is silicone-based and does not absorb moisture, making it suitable for the motorcycle's braking system. Always check the owner's manual for specific recommendations and ensure the brake fluid is clean and properly maintained.
DOT 3, DOT 4 or DOT 5.1 (but NOT DOT 5, which is silicone brake fluid) can be used in your car.
If you accidentally mix silicone brake fluid (such as DOT 5) with regular brake fluid (like DOT 3, 4, or 5.1), the best course of action is to completely flush the brake system. This ensures the incompatible fluids do not compromise braking performance. You should replace all brake fluid with the appropriate type for your vehicle and check for any potential damage to rubber components, as the mixture can cause corrosion or degradation. It's advisable to consult a professional mechanic for proper servicing.
Because oils damage rubber seals and hoses in the braking system, brake fluids are not petroleum-based. Most brake fluids used today are glycol-ether based, but mineral oil (Citroën liquide hydraulique minéral (LHM) and silicone (DOT 5) based fluids are also available.
