Does brake fluid Dot matter?
YES! It’s very important– the fluid specified by the original vehicle manufacturers must be used. DOT 3 & 4 brake fluid is a mineral based fluid. DOT 5 is silicone based.
Can you use dot for brake fluid instead of dot three?
Yes, DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point. DOT 5.1 is used in high-performance and heavy-duty applications due to its high boiling point. DOT 5 brake fluid is silicone, meaning it doesn’t absorb water.
What is the difference in DOT brake fluid?
DOT 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.
What is the difference between DOT3 and DOT 5?
While both fluids are glycol ether based, DOT4 contains a certain amount of borate ester which allows it to handle more heat. While DOT5 has a higher boiling point (500F dry/356F wet) than DOT3 or DOT4, DOT5 exhibits more compressibility than glycol ether brake fluid.
What happens if you put DOT3 instead of DOT 4?
A vehicle that requires DOT 4 might boil the brake fluid if a DOT 3 (a temperature downgrade) is used. The two mix together OK, because both are polyglycol-ether -based fluids. In very heavy braking DOT 3 fluid has a potential to boil from heat and make the brakes spongy.
What’s the difference between dot 3 and DOT 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.
Which is better DOT 4 or dot 5?
This makes it far more compressible in nature. However, some Dot 4 brake fluids are made with high boiling points too. For this reason, everyday people would have no use for a Dot 5 because there are Dot 4 brake fluids which are made for extreme heat too.
What’s the boiling point of DOT 5 brake fluid?
DOT 5 is a silicone-based brake fluid and has a very high boiling point of 500 degrees Fahrenheit. Usually it has a purple color to differentiate from the amber color of DOT 3 and 4.
Can you mix dot 5 with DOT 3?
DOT 5 is not able to be mixed with any other fluid, and is 4x more expensive than DOT 3. DOT 5.1 is a glycol-based brake fluid with a boiling point similar to DOT 4 racing brake fluids. Usually clear to amber in color. While it is technically intermixable with DOT 3 or 4, it is not recommended.

Which is better dot 3 or dot 5?
DOT 5.1 is a glycol-based brake fluid with a boiling point similar to DOT 4 racing brake fluids. Usually clear to amber in color. While it is technically intermixable with DOT 3 or 4, it is not recommended. DOT 5.1 is around 14x more expensive than DOT 3.
DOT 5 is a silicone-based brake fluid and has a very high boiling point of 500 degrees Fahrenheit. Usually it has a purple color to differentiate from the amber color of DOT 3 and 4.
How can you tell the difference between brake fluid?
You can tell the brake fluids apart by the designation they are given. This identifies the chemical mixture used to formulate the fluid. All brake fluids must abide by the standards of the U.S. Department of Transportation. The three most popular brake fluids are Dot 3, Dot 4, and Dot 5.
