What’s the difference between dot3 and dot4? How would you know if you put DOT 3 in DOT4 instead? No, you can’t mix dot3 and dot4. When we write this post, we’re going to look at the differences between dot 3 and dot 4.
There is also a need for you to know what brake fluid does in order to fully understand the brake fluid ratings and what they mean. It’s a type of hydraulic fluid that is used to move force from a brake pedal. It’s called brake fluid.

There are other ways you can use it. You can also use it to move the brake lever to the brake caliper or wheel cylinder, which will turn it into pressure.
These are called “brake pads” and “rotors.” When they are pressed by the caliper or wheel cylinder, they will make friction, which will slow the car down.
In other words, brakes turn kinetic energy into heat, which is where brake fluid ratings come in. They also show how much brake fluid can boil when it is dry or wet. In what amount of time does it take to get a leak in the transmission fixed?
Keep in mind that brake fluid has glycol in it, which draws water. When you buy a bottle of brake fluid, you’ll see that it has both a wet and dry boiling point number on the label. This is because over time, brake fluid is going to get a certain amount of moisture in it.
What is the difference between dot3 and dot4 brake fluid
When it comes to brake fluid, dot 3 and dot 4 are very different from each other.
DOT3 brake fluid will hold more water over time than DOT4 fluid, so you’ll need to change your fluid less often.
People who live in hot places should use the DOT 4 brake fluid because it has higher wet and dry boiling points than other types of fluid.
Are All DOT 3 Brake Fluids Compatible?
If you want to know this, the answer is no, they are not chemically the same.
However, they are only all guaranteed to meet the DOT specification, which is mostly a measurement or specification of how well they work.
However, this may also have an effect on some parts of the chemical makeup.
But keep in mind that manufacturers can put in any extras they want to meet or exceed the DOT standard.
The truth is that the brand you choose can make a difference, but if they meet the DOT standard, they should at least meet the baseline.
can you mix dot3 and dot4 brake fluid
Yes.
It’s safe to mix the dot 3 brake fluid with the dot 4 fluid, and there are no risks. Because of its high boiling point, DOT 4 brake fluid can be used in more heavy-duty and high-performance vehicles than DOT 3. This is because DOT 4 can be used in these vehicles instead of the DOT 3.
DOT 3 Vs DOT 4 Brake Fluid: Is There a Difference Between DOT 3 And DOT 4 Brake Fluid
DOT number: 3, 4, 5.1. Glycol-based brake fluids are classified by this number: 3, 4, 5.1.
However, these brakefluids don’t have to be categorized by chemical composition because there aren’t any government rules about how they should be done.
It means that there isn’t a standard formula for brake fluid, so there isn’t one. People mean that they have to meet certain government rules.
The DOT3 is the most common type of brake fluid used by people who drive every day.
A lot of cars and trucks use this type. Importantly, it’s for cars that don’t use their brakes too aggressively, which means cars that don’t turn the kinetic energy into heat that DOT 3 can’t handle.
However, the DOT4 has a higher boiling point and has also found a place in racing vehicles and police cars, which is why it is used more often. This is because more people are using ABS and traction control. The DOT4 has also started to become more popular because of this.

Their “Heat” Points
Boiling points are one big difference between the two types of dot3 and dot4 paint. How much water they can take in and how quickly the fluid evaporates are two things that boil point tells us about.
Even so, both the DOT3 and DOT4 are hygroscopic, which means that they can take in water.
There is one problem with this: Because of its low boiling point, the DOT3 is more likely to get water in. When you brake very hard, the DOT3 boils more quickly, which makes the DOT3 less good for some things.
It’s important to note that there are two types of boil points: dry and wet.
However, to figure out the dried boiling point, you can use the fluid from a new bottle.
As for the wet boiling point, you can figure it out by using a fluid that has been mixed with about 3.7% water.
You might be able to let water into the system every time you open the reservoir cap and put in more fluid, which will make it worse.
This means that you should make sure to flush the brake system from time to time to get rid of the water.
Check out the table below:
They have chemical structures.
Because both of them meet the requirements on the table above, there aren’t any specific rules for their chemical structure as long as they both meet those requirements.
Most of the time, the DOT3 brake fluid is made of diethyleneglycol (DEG). There is no rule about this, but producers might be more cost-effective by meeting the rules that were set out.
So, this means that the brake fluid industry has decided that this is the standard.
The DOT4 is made up of glycol and a borate ester. This borate is for the brake fluid to be able to handle higher temperatures. When you look at the table above, the dry and wet boiling points are both higher than they were.
Is Prestone DOT 3 Brake Fluid Good?
In order for the brake system to work properly, it needs to be filled with Prestone DOT 3 Brake Fluid, which is made up of polyglycol ethers.
The fluid can be used with disc and drum brakes, as well as with anti-lock brakes (ABS). The fluid’s wet and dry boiling points are higher than the government’s minimum standards, which gives an extra layer of protection when the brakes are used in very dangerous ways.
DOT 3 is one of the most common brake fluids for passenger cars, and it costs a fair amount.
This fluid is more than enough for most people who drive every day and don’t need a lot of performance-oriented results from their brakes.
Using just one 32-ounce bottle is enough to completely flush a single car’s brake system.
What Is The Best DOT 3 Brake Fluid Freon?
Because dirty or old brake fluid can build up rust or other deposits, it needs to be changed all the time.
Even so, you should always check with your car’s manufacturer when it comes to choosing a brake fluid, though.
This is also according to what the manufacturer says. The brake fluid should also be flushed or completely changed.
You should be careful with brake fluid, because it is very acidic and can damage your paint or other surfaces if it gets on them.
If you eat them, they can hurt you, and you should keep them away from your skin or eyes.

The Prestone DOT 3 brake fluid is made up of polyglycol ethers, which keep the brake system from making dangerous vapours.
The fluid can be used with disc and drum brakes, as well as with anti-lock brakes (ABS). During a very hard braking situation, the fluid’s wet and dry boiling points are higher than the government’s minimum standards. This gives the driver a little extra safety cushion.
DOT 3 is one of the most common brake fluids for passenger cars, and it costs a fair amount.
This fluid is more than enough for most people who drive every day and don’t need a lot of performance-oriented results from their brakes.
Using just one 32-ounce bottle is enough to completely flush a single car’s brake system.
If you buy this product online, it might not come with a lid, and the seal might even break while it’s on its way to you.
Since water gets into the brake fluid more quickly when it has been broken, this is not good. Besides that, it can also get dirty if the package isn’t sealed properly, which can happen. If you want to buy it on Amazon, you can get it there for $3
#3. The Lucas Oil Dot 3 Synthetic Brake Fluid
A high-quality formulation makes me think that this brake fluid is one of the best on the market.
This brake fluid can be used with any rubber braking system. It can also be mixed with other glycol-based braking fluids.
In order for the brake fluid to protect and strengthen the brakes, it needs to be added to them.
For one thing, it meets and exceeds the industry’s minimum dry boiling point of about 401 degrees Fahrenheit. This makes it one of my top three picks for the best DOT3 brake fluids.
There are two types of brakes that can be used with this: disc or drum brakes. It can also be used with a clutch.
The fluid helps protect your brakes from rust and corrosion, stops rubber parts from hardening or softening too much, and is very good at lubricating. You can buy this fluid on Amazon for just $8.
What Will Happen If You Accidentally Put DOT 3 In DOT4
Check to make sure that nothing bad will happen to the brake system itself! They work with each other.
But you should know that the DOT 4 can boil faster than the DOT 3. Your car’s brakes will work hard enough to boil DOT 3 brake fluid, which means it needs to have it. You will lose your brake power quickly if that happens, so don’t do that!
Conclusion
I can tell you for sure that the main difference between DOT3 and DOT4 fluids is how quickly they boil.
These fluids don’t change very much, except for the DOT4 that has borate in it to make it boil faster.
To change the brake fluid, it’s best to check with the manufacturer. Check out this: No, Hydraulic Fluid is not flammable
