What brake fluid does a 2014 Mustang V6 use?

The 2014 Ford Mustang V6 uses DOT 4 brake fluid that meets SAE J1703/J1704 standards. It is a glycol-based fluid with a higher boiling point than DOT 3, and Ford typically warns against using silicone-based DOT 5 in this braking system.


Brake fluid specifications for the 2014 Mustang V6


Brake fluid is a critical part of the hydraulic braking system. For the 2014 Mustang V6, the recommended fluid is DOT 4, chosen for its higher boiling point and reliability under typical and performance driving conditions. DOT 4 fluids are glycol-based, hygroscopic (they absorb moisture over time), and need periodic replacement to maintain braking performance. Silicone-based DOT 5 fluids are not compatible with standard ABS braking systems used on this model, and should be avoided.


To verify the exact requirement for your car, check the reservoir cap for the fluid spec label or consult the owner's manual. If you are replacing fluid after a service interval or a brake system issue, using DOT 4 that meets SAE J1703/J1704 is the standard and widely recommended practice for most 2010s Mustangs.


To help you confirm you’re buying the right fluid, note these compatibility guidelines:



  • Use DOT 4 brake fluid that meets SAE J1703/J1704 for the 2014 Mustang V6.

  • DOT 4 is glycol-based and provides a higher boiling point than DOT 3, improving resistance to brake fade.

  • Avoid silicone-based DOT 5 fluids in this vehicle, as they are not compatible with the standard ABS/brake system used on this model.

  • Choose a brand with a respectable dry boiling point (typically 230°C or higher) to ensure optimal performance, especially in hot or spirited driving.


Concluding: Paying attention to these guidelines helps maintain braking performance and ABS reliability. When in doubt, refer to the owner's manual or ask a Ford service professional to confirm the exact spec for your vehicle.


Where to verify the specification


The simplest way to confirm the exact brake fluid requirement is to look at the brake fluid reservoir cap or the maintenance section of the owner's manual. Ford typically indicates the required fluid type on the cap itself or in the quick-start/mayhem sections of the manual for the 2014 Mustang V6. If you cannot locate the information, contact a Ford dealer or certified mechanic for confirmation.


Maintenance and replacement guidance


Brake fluid should be replaced on a schedule that reflects driving conditions and climate, typically every 2 years or as specified in the owner's manual. When replacing, perform a proper bleed to remove air from the lines, starting with the farthest brake Caliper from the master cylinder and following the vehicle’s recommended bleeding sequence. If you’re not comfortable performing the service yourself, a professional brake bleed is recommended to ensure system integrity.


Summary


For a 2014 Mustang V6, use DOT 4 brake fluid meeting SAE J1703/J1704, a glycol-based fluid with a higher boiling point than DOT 3. Avoid silicone-based DOT 5. Check the reservoir cap or owner's manual to confirm the exact spec, replace fluid per the maintenance schedule, and have a professional perform a bleed if you’re unsure about the procedure.

Is it okay to mix DOT 3 and dot 4 brake fluid?


Yes, you can mix DOT 3 and DOT 4 brake fluid, as they are chemically compatible, but you should never mix them with DOT 5. Mixing DOT 3 and DOT 4 is acceptable because both are glycol-based. Adding DOT 4 to DOT 3 will lower its boiling point, while adding DOT 3 to DOT 4 will lower its boiling point.

Compatibility and mixing

  • DOT 3 and DOT 4: These are compatible and can be mixed without causing harm to the braking system. 
  • DOT 3, 4, and 5.1: These are all compatible with each other and can be mixed. 
  • DOT 5: This is silicone-based and is not compatible with DOT 3, DOT 4, or DOT 5.1. Mixing them will cause the system to fail. 

What to consider when mixing
  • Boiling point: DOT 4 has a higher boiling point than DOT 3. Mixing them will lower the overall boiling point of the fluid in your system. 
  • Performance: If your car requires DOT 4 and you mix it with DOT 3, you will reduce the braking system's performance. 
  • Best practice: It is best to check your vehicle's manual and use the specific DOT fluid recommended for your car. If you need to upgrade to DOT 4, it is best to completely flush the old DOT 3 fluid out first to get the full benefits of the DOT 4 fluid.

Do I want DOT 3 or dot 4 brake fluid?


You should use DOT 3 or DOT 4 brake fluid based on your vehicle's manufacturer specifications, which can be found in your owner's manual. If your car requires DOT 3, you can upgrade to DOT 4 for its higher boiling point, which is beneficial for high-temperature braking or frequent use, but do not use DOT 3 if your car calls for DOT 4. 
When to use DOT 3

  • Daily driving: Most standard cars and trucks use DOT 3 for moderate braking conditions. 
  • If specified: Always use DOT 3 if it is the fluid specified by your vehicle's manufacturer. 

When to use DOT 4
  • For higher performance: DOT 4 has higher boiling points, making it better for high-performance vehicles or situations where brakes are used frequently, like in hilly terrain or towing. 
  • If specified: Some modern vehicles, especially those with ABS systems, may specifically require DOT 4. 
  • Upgrading from DOT 3: If your car currently uses DOT 3, you can upgrade to DOT 4 for improved performance and a higher safety margin. The two are compatible and can be mixed, though it's generally recommended to use the higher-spec fluid if you have the option. 

Key differences
  • Boiling points: DOT 4 has higher dry and wet boiling points than DOT 3, meaning it can withstand higher temperatures before it begins to boil and lose effectiveness. 
  • Moisture absorption: Both fluids are hygroscopic, meaning they absorb moisture over time, which lowers their boiling point. Because DOT 4 has a higher starting boiling point, it has more of a buffer before becoming a safety risk. 

Important considerations
  • Check your manual: Always refer to your car's owner's manual for the correct brake fluid specification to ensure compatibility and prevent system damage. 
  • Do not use lower-spec fluid: Never use a lower-spec fluid (like DOT 3) in a vehicle that requires a higher-spec fluid (like DOT 4). 
  • Do not mix DOT 3 and DOT 5: While DOT 3 and DOT 4 are compatible, DOT 5 is silicone-based and should not be mixed with either glycol-based DOT 3 or DOT 4 fluids.
