Ford recommends using DOT 4 Low Viscosity (LV) High Performance Brake Fluid or an equivalent fluid that meets the WSS-M6C65-A2 specification. It is important to use the recommended brake fluid to ensure optimal brake performance and meet Ford’s performance standards. Using any other fluid may cause degraded brake performance.

What happens if you mix DOT 3 and DOT 4 brake fluid?
Are DOT 3 and DOT 4 Brake Fluid Compatible? Yes. DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point.
What brake fluid do most manufacturers recommend?
By far, DOT 3 is the most popular. It’s been in use for a very long time. Fresh DOT 3 has a boiling point of 401 degrees Fahrenheit; fully degraded, it drops to 284 degrees Fahrenheit.
Does Ford recommend changing brake fluid?
Throughout the life of your Ford F-150 your brake fluid will need to be replaced at every 3-year interval. Brake fluid is used to protect the metals that make up your brake components. It also helps stop corrosion caused by moisture in the system.
What happens if I mix DOT 3 and DOT 4 brake fluid?
DOT 3 and DOT 4 are both glycol ether based, and will mix just fine. DOT 4 has a higher boiling point, so depending on the application, it may be necessary to use that instead of DOT 3. Do not mix DOT 5 with either of them, as it is silicone based.
Can you mix DOT 3 and DOT 4?
And Dot 4 are glycol ether-based fluids and the main difference lies in their boiling points DOT. 4 has a higher boiling point meaning it can handle higher temperatures without causing brake failure.
Does it matter what brand of brake fluid I get?
Although DOT 3 and DOT 4 fluids are all glycol-based, the chemical composition of each type of fluid is different, so it will have a different effect on the system. To make sure the system works as it should, the best thing to do is to keep using the brake fluid recommended by the manufacturer.
Does Ford use DOT 3 brake fluid?
DOT4 brake fluid is not “better” than DOT3, in the same way that diesel is not better than gasoline or jet fuel. They’re different – they have different applications. All these trucks are designed to use DOT3 – that’s what will give the best performance.
Can I use DOT 4 instead of DOT 3 brake fluid?
1 Answer. You can absolutely use DOT4 in place of DOT3 brake fluid. The only thing you’ll need to do is completely purge the system of the old DOT3 fluid to take advantage of the DOT4 features (higher boiling point both dry/wet). The only real difference between the two is how hot they can get before they boil.
Should I use DOT 3 or 4 brake fluid?
The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you’ll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.
Is it OK to mix different brands of DOT 3 brake fluid?
2 Answers. tl dr – Mixing Brand X fluid with Brand Y fluid is of no consequence, as long as you are mixing the same grade of fluid (DOT3, 4, 5, or 5.1). In order to be rated at a given grade, it must meet the prerequisites of the grade. This has to do with wet/dry boiling points, not who makes it.
