Does the Acura TSX take DOT 3?
The Acura TSX typically uses glycol-based brake fluid, most commonly DOT 3. You can use DOT 4 as an upgrade for higher boiling points, but avoid silicone-based DOT 5. Always check the specific owner's manual for your year and market to be sure.
Brake fluid requirements by TSX generation
The TSX was produced in two generations, and the core guidance remains glycol-based brake fluid. Here is a general, year-spanning view of what most manuals recommend.
- First generation (2004–2008): DOT 3 brake fluid is the standard specification in most owner manuals. DOT 4 is acceptable as an upgrade if you want higher boiling performance.
- Second generation (2009–2014): DOT 3 remains the baseline recommendation, with DOT 4 commonly used as an upgrade option for better performance in demanding conditions.
In short, DOT 3 is the baseline for the TSX across generations, and DOT 4 is an acceptable upgrade. Do not use DOT 5 silicone-based fluid in these vehicles.
Choosing between DOT 3 and DOT 4
When deciding which fluid to use in your TSX, consider needs like daily driving versus spirited or hot-weather driving, and how you plan to maintain the car.
- Boiling point and moisture handling: DOT 4 has higher dry and wet boiling points than DOT 3, which can help under heavy braking or in hot climates.
- Compatibility and mixing: DOT 3 and DOT 4 are both glycol-based and generally compatible with each other. If you switch from one to the other, a full system flush is recommended. Do not use silicone-based DOT 5 in a system designed for glycol-based fluids.
- Practical recommendation: For typical daily driving, DOT 3 is usually sufficient. For track days, high-performance driving, or extreme heat, DOT 4 provides extra margin.
Ultimately, both DOT 3 and DOT 4 are compatible with the TSX. Choose DOT 3 for standard use and DOT 4 if you want greater margin under demanding conditions, ensuring you avoid DOT 5.
Maintenance and replacement tips
Maintaining clean brake fluid is key to braking performance and long-term health of the system. Here are practical guidelines to follow for the TSX.
- Regular checks: Inspect fluid color and level. Clear or light straw-colored fluid is typical; dark or muddy fluid indicates moisture and contamination.
- Replacement intervals: Plan for a brake fluid flush every 2–3 years, or sooner in high-humidity climates or with frequent heavy braking.
- Flushing and topping: If replacing, perform a full system flush to remove old fluid and moisture. Use only the recommended DOT grade and avoid mixing incompatible fluids.
- Safety note: Do not use DOT 5 silicone-based fluid in a TSX unless a certified mechanic has confirmed compatibility with your specific brake system.
Following these guidelines helps prevent moisture buildup, boil-off under braking, and corrosion in the hydraulic system.
Summary
Yes—your Acura TSX generally uses DOT 3 brake fluid, with DOT 4 available as an upgrade for higher boiling points. Do not use DOT 5 silicone-based fluid. Always verify the exact specification in your vehicle’s owner’s manual for your model year and market, and follow recommended maintenance intervals to keep braking performance reliable.

What type of oil does the Acura TSX take?
The Acura TSX oil type depends on the model year, but generally, for 2011-2014 models, 0W-20 full synthetic is recommended, while 2004-2008 models typically require 5W-30 synthetic blend or full synthetic. Older models like the 2009-2010 require 5W-20 or 0W-20. Always confirm the exact requirement in your owner's manual, and ensure the oil meets the API Certification Seal.
By model year
- 2011–2014 TSX: Use 0W-20 ultimate full synthetic blend.
- 2009–2010 TSX: Use 5W-20 synthetic blend or 0W-20 ultimate full synthetic blend.
- 2004–2008 TSX: Use 5W-30 synthetic blend or full synthetic.
Important considerations
- Check your owner's manual: This is the most reliable source for your specific vehicle's requirements.
- API Certification Seal: Use an oil that has this seal, which ensures it meets the American Petroleum Institute's standards for quality and performance.
- Synthetic oil: You can use synthetic oil as long as it has the API certification and the correct viscosity grade. Using synthetic oil is acceptable and recommended, even if the owner's manual specifies conventional oil.
- 0W-20 vs. 5W-20: While some 2009-2010 models might specify 5W-20, 0W-20 is a suitable alternative that can provide better cold starts and is easier to find.
What brake fluid does Acura use?

Does my car need DOT 3 or DOT 4 brake fluid?
Daily driving or commuting – DOT 3 is typically sufficient for light, everyday use where brake temperatures stay moderate. Towing, heavy loads, or mountainous driving – DOT 4 or DOT 5.1, with their higher boiling points, are better suited for these conditions to prevent brake fade.
