Approximately 4.7 quarts (about 4.4 liters) of engine oil are required for a full change on the 2011 TSX 2.4L, including a new filter.
The official capacity for this engine, as listed in Acura/Honda service data, is about 4.7 quarts with a filter. When performing an oil change, start by adding oil to bring the level toward the full mark on the dipstick after running the engine briefly and then checking the level after it has cooled.

Recommended oil type and change guidelines
Guidance on oil grade and maintenance interval for the 2.4L engine.
- Viscosity: 5W-20 synthetic blend or full synthetic, as specified in the owner's manual; in very cold climates, 0W-20 may be acceptable per manual or dealer guidance.
- Change interval: typically every 5,000 miles (8,000 km) under normal conditions; shorter intervals (about 3,750 miles / 6,000 km) may be advised for severe driving conditions or frequent short trips.
Use a quality oil filter that meets OEM standards and dispose of used oil responsibly. After changing, reset the oil life monitor if your vehicle is equipped with one.
Practical tips for performing the oil change
These steps help ensure a smooth and proper oil change on the 2011 TSX 2.4L.
- Gather supplies: the correct oil type (5W-20), a new oil filter, a drain pan, a wrench, funnel, and a replacement drain plug washer if needed.
- Warm the engine slightly to help drain, then safely lift the front of the car if needed and secure it on stands or ramps.
- Place the drain pan beneath the oil pan, remove the drain plug, and allow all old oil to drain completely.
- Remove the old oil filter, noting how it’s installed, and replace it with a new filter, lightly coating the gasket with fresh oil.
- Replace the drain plug with a new washer if necessary, snug to specification without over-tightening, and wipe up any spills.
- Fill with approximately 4.7 quarts of oil using a funnel, then start the engine and let it run for a minute before turning off. Wait a few minutes for the oil to settle, then check the level and add oil as needed to reach the full mark.
- Check for leaks, replace the oil fill cap, and reset maintenance reminders if applicable.
Always handle used oil and filters responsibly and follow local regulations for disposal.
