Maintaining your Acura TSX is essential for optimal performance and longevity. This model, produced from 2004 to 2014, features five different engine options, including the powerful J35Z6 3.5L V-6 and various 2.4L I-4 engines such as the K24A2 and K24Z3. Depending on the engine, oil capacities range from 4.2 to 4.5 quarts, with recommended viscosities of 0W-20 for the J35Z6 and K24Z3 engines, and 5W-30 for the K24A2. The coolant capacities also vary, with the J35Z6 requiring 7.1 quarts and the K24A2 needing 5.7 or 7.7 quarts depending on the year.
Regular oil changes are crucial to keep your TSX running smoothly. For the J35Z6 engine, you should use high-quality synthetic oil to maintain its performance, while the I-4 engines can use either conventional or synthetic oil based on your preference.

How many quarts of oil does the Acura TSX take?
The oil capacity for the Acura TSX varies by engine. The J35Z6 engine takes 4.5 quarts, the K24A2 engines take 4.4 quarts, and the K24Z3 engines take 4.2 quarts.
How often should I change oil in a Acura TSX?
It is recommended to change the oil in your Acura TSX every 5,000 to 7,500 miles, depending on your driving conditions and the type of oil used. Always refer to your owner's manual for specific guidelines.
What is the coolant capacity of the Acura TSX?
The coolant capacity varies by engine in the Acura TSX. The J35Z6 engine requires 7.1 quarts of coolant, while the K24A2 engines need either 5.7 or 7.7 quarts, depending on the model year.
Does the Acura TSX need synthetic oil?
While synthetic oil is not strictly necessary for the Acura TSX, it is highly recommended for the J35Z6 engine to enhance performance and protection. The K24A2 and K24Z3 engines can use either conventional or synthetic oil.
What happens if I use the wrong oil viscosity in my Acura TSX?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to use the recommended viscosity for your specific engine to ensure optimal performance.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks your engine's oil condition based on various factors such as temperature, driving habits, and mileage. It helps determine when an oil change is necessary, ensuring that you maintain optimal engine health.
Can I mix synthetic and conventional oil?
While it is technically possible to mix synthetic and conventional oil, it is not recommended. Mixing can dilute the benefits of synthetic oil and may lead to reduced performance and protection.
How do I know if my Acura TSX has an oil leak?
Signs of an oil leak in your Acura TSX include oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regularly checking your oil levels can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets, leading to oil burning in the combustion chamber. Regular maintenance and timely oil changes can help mitigate this issue.
Should I check my oil when the engine is hot or cold?
It is best to check your oil when the engine is warm, as this allows the oil to circulate and provide a more accurate reading on the dipstick. However, ensure the engine is turned off and has cooled slightly to avoid burns.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, while an oil flush is a process that cleans the engine's oil passages and removes sludge and deposits. Flushing is typically not necessary for regular maintenance.
