Is there a difference between DOT 4 and Super Dot 4 brake fluid?
Brake fluid is a critical component of a vehicle's braking system, and it's important to understand the differences between the various types available. In this article, we'll explore the key distinctions between DOT 4 and Super DOT 4 brake fluids.
What is DOT 4 Brake Fluid?
DOT 4 brake fluid is a common type of brake fluid used in many vehicles. It is a glycol-based fluid that meets the DOT 4 specification set by the U.S. Department of Transportation (DOT). DOT 4 brake fluid is designed to withstand high temperatures and pressures, and it has a higher boiling point than DOT 3 brake fluid. This makes it more suitable for use in modern, high-performance braking systems.
What is Super DOT 4 Brake Fluid?
Super DOT 4 brake fluid is a more advanced version of DOT 4 brake fluid. It is also glycol-based, but it has been formulated to have an even higher boiling point and better resistance to heat and pressure. Super DOT 4 brake fluid is designed to provide enhanced performance and longer-lasting protection for high-performance braking systems.
Key Differences Between DOT 4 and Super DOT 4 Brake Fluid
- Boiling Point: Super DOT 4 brake fluid has a higher dry and wet boiling point than standard DOT 4 brake fluid, making it better suited for high-performance applications.
- Viscosity: Super DOT 4 brake fluid has a lower viscosity, which allows it to flow more easily through the brake system and provide better responsiveness.
- Compatibility: While both DOT 4 and Super DOT 4 brake fluids are compatible with most vehicles, it's important to check the manufacturer's recommendations to ensure you're using the appropriate type.
In summary, the primary difference between DOT 4 and Super DOT 4 brake fluid is the enhanced performance and heat resistance of the Super DOT 4 formulation, making it a better choice for high-performance vehicles or those that experience frequent, heavy braking.
Is super dot 4 the same as DOT 4?
There is a general acceptance that “the higher, the better” and therefore, from this viewpoint Super DOT 4 is better than DOT 4 which, in turn is better than DOT 3. Indeed the difference between the three specifications is in terms of the boiling point.
Which brake fluid can not be mixed together?
The brand doesn't matter. DOT 3 and DOT 4 can be mixed. DOT 4 just has a higher boiling point. DOT 5 is silicone based and should not be mixed with other brake fluids.
Can you mix synthetic DOT 4 with regular DOT 4?
Out of all three types, only synthetic brake fluids are miscible.
Is pentosin super dot 4 low viscosity?
DOT 4 LV stands out with its remarkably low viscosity at cold temperatures, making it a perfect fit for vehicles operating in cold environments.
Can you mix DOT 4 and super dot 4 brake fluid?
MIXING BRAKE FLUIDS
DOT 3, DOT 4, Super DOT 4 and DOT 5.1 fluids are miscible although this is not recommended. DOT 5 fluid is NOT mixable with DOT 3, DOT 4, Super DOT 4 or DOT 5.1 fluids.
Is DOT 4 the same as DOT 4 esp?
A low viscosity (LV) brake fluid designed to enable the use of the Electronic Stability Programme (ESP) via the Anti-Lock Braking System (ABS). It has a lower viscosity compared to a 'standard' DOT 4 fluid, so will operate effectively over a wide temperature range.
Can I just add brake fluid without flushing?
Yes, you can. You can add brake fluid without removing the old fluid from your reservoir. If your brake system is not exposed to air, then it's okay.
Is DOT 4 and DOT 4 plus the same?
Both the SAE and ISO standards say brake fluid can be called DOT 4 Plus, DOT 4 Super, or DOT 4 Low Viscosity or LV. They even call this Class 6 Brake Fluids by some engineers. You may run across these names in the vehicle fluid specifications or on the brake fluid reservoir cap.
What is the best brand of DOT 4 brake fluid?
The Valvoline DOT 4 Brake Fluid 32 ounce is an excellent choice if you fall into either category. It's safe for a range of braking systems, including ABS, disc, and drum, and it can help you defeat corrosion and keep your brake system running, even in higher temperatures.
Does it matter what DOT 4 brake fluid I use?
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.
