The 2012 Acura TSX with a 2.4-liter engine typically requires about 4.5 quarts of oil when performing an oil change with a new filter.
For reference, the engine’s total capacity is slightly higher when the filter is included, and lower if you do not replace the filter. In practice, plan to add 4.5 quarts and then verify the level with the dipstick, topping up as needed to reach the full mark.
Oil capacity specifics
Below are the official figures commonly cited for the 2.4 L TSX engine. Variations can occur by market or engine build, so always check your owner's manual or the under-hood label for the exact figure.
- Oil capacity with the oil filter installed: 4.5 quarts (approximately 4.3 liters)
- Oil capacity without replacing the filter: about 4.2 quarts (approximately 4.0 liters)
After pouring in the listed amount, always verify the oil level with the dipstick and adjust as needed to reach the full mark. Using synthetic oil or a different viscosity does not change the capacity figure; it affects lubrication characteristics but not the total volume required.
Practical notes for owners
For accuracy and engine longevity, follow the official maintenance schedule, use the recommended viscosity, and replace the filter during every oil change. If you’re unsure which variant you have, consult your vehicle’s manual or contact a dealer.
Summary
The standard oil capacity for the 2012 Acura TSX 2.4 L is 4.5 quarts with a filter, about 4.2 quarts without. Always verify on your vehicle and consult the manual for the exact figure for your specific car.
