If you accidentally put Dot 3 in Dot 4, there is no need to worry. Both fluids are compatible with each other and will not cause any damage to your car. However, it is important to note that Dot 4 brake fluid has a higher boiling point than Dot 3, so if you are planning on using your car in high performance driving or racing conditions, it is best to use the correct fluid.
If you have accidentally put Dot 3 in your Dot 4 brake fluid reservoir, don’t panic. Although these two types of brake fluid are not compatible, mixing them in small amounts will not cause any damage to your braking system. However, it is important to flush out the reservoir and replace the fluid with fresh Dot 4 as soon as possible.
Dot 4 vs Dot3 Brake Fluid (What are Major Difference Between Dot 3 and Dot 4 Brake Fluid)
What Happens If I Put Dot 3 Instead of Dot 4?
If you put DOT 3 instead of DOT 4, your car’s brakes may not work as well. DOT 3 brake fluid is less viscous than DOT 4 and has a lower boiling point. This means that it is more likely to leak out of seals and reservoirs, and it will not absorb as much heat from the brakes.
What Happens If I Mix Dot 3 And Dot 4 Brake Fluid?
If you mix DOT 3 and DOT 4 brake fluid, the DOT 4 will degrade and become less effective. The two fluids are not compatible with each other and should not be mixed.

Dot 3 Vs Dot 4 Motorcycle
Dot 3 and Dot 4 motorcycle brake fluids are both glycol based fluids, but they differ in their boiling points. Dot 3 has a lower boiling point than Dot 4, which means it is less effective at dissipating heat. However, Dot 3 is less likely to cause corrosion and is compatible with most seals and paint finishes.
What Happens If You Mix Dot 3 With Dot 4
If you mix Dot 3 with Dot 4, the DOT 4 will gel. This can cause your brakes to feel spongy, and in some cases, fail altogether. If you’re going to use a different brake fluid, make sure to bleed your brakes completely before adding fresh fluid.
Dot 3 Brake Fluid Specification
Dot 3 Brake Fluid Specification
Brake fluid is a type of hydraulic fluid used in brake systems. It is also known as hydraulic fluid or brake oil.
There are three main types of brake fluid: Dot 3, Dot 4, and Dot 5.1.
Dot 3 brake fluid is the most common type of brake fluid. It is made from glycol and can withstand temperatures up to 205 degrees Celsius (401 degrees Fahrenheit).
Dot 3 brake fluid should be replaced every two years or 24,000 miles (40,000 kilometers), whichever comes first.
Dot 4 brake fluid is made from polyglycol and can withstand temperatures up to 230 degrees Celsius (446 degrees Fahrenheit). Dot 4 brake fluids should be replaced every four years or 48,000 miles (80,000 kilometers), whichever comes first.
Dot 5.1 brake fluid is made from silicone and can withstand temperatures up to 260 degrees Celsius (500 degrees Fahrenheit). Dot 5.1 fluids do not absorb moisture like the other types of fluids, so they have a longer lifespan – typically six years or 96,000 miles (160,000 kilometers). However, they are not compatible with other types of fluids so you must use only Dot 5.1 in your system if you switch to it.
Conclusion
If you accidentally put Dot 3 in your Dot 4 brake fluid reservoir, don’t worry. The two types of fluid are compatible, and you can top off the reservoir with Dot 4.
