The 2017 Acura ILX oil capacity is precisely 4.4 US quarts (4.2 liters) when replacing the oil filter during a standard service. If you're only draining and refilling the crankcase without swapping out the filter, the engine takes about 4.0 US quarts. Knowing these exact numbers prevents you from either underfilling or overfilling the 2.4-liter direct-injected engine under your hood.
Acura pairs this sedan with a high-compression Earth Dreams engine, meaning fluid specifications matter. Using the wrong viscosity or an incorrect volume drops fuel economy and accelerates wear on internal components. Let's look at the exact oil grades, filter part numbers, and practical steps required to do the job right.
Exact Oil Specifications and Viscosity Grades
Factory specifications for the 2017 ILX require SAE 0W-20 full synthetic oil carrying the API Certification Seal. While 5W-20 is acceptable in older Honda or Acura models, 0W-20 is the primary recommendation here because it flows more rapidly at startup, protecting tight bearing clearances in cold weather while maintaining film strength at high operating temperatures.
- Primary Viscosity: SAE 0W-20
- Alternative Viscosity: SAE 5W-20 (only if 0W-20 is unavailable; switch back at the next service)
- Oil Type: Full Synthetic meeting Honda Service Express fluid standards or ILSAC GF-5 specifications
- Oil Change Interval: 7,500 miles under normal driving conditions, or 3,000 to 5,000 miles for severe service (short trips, extreme idling, dusty roads)
Tools and Supplies Needed for an Oil Change
Gathering your equipment beforehand makes the job cleaner and faster. Working on a 2017 ILX requires basic metric hand tools and a low-profile drain pan because the sedan sits lower than standard SUVs.
- 4.5 quarts of 0W-20 full synthetic motor oil
- Replacement oil filter (OEM part number 15400-PLM-A02 or an equivalent high-efficiency filter like Fram, WIX, or Mobil 1)
- New crush washer for the drain plug (typically 14mm)
- 17mm socket and ratchet
- Oil filter wrench (cap style works best in tight engine bays)
- Clean shop rags, funnel, and a drain pan
Step-by-Step Procedure to Change Your ILX Oil
Changing oil at home saves money and lets you inspect the underside of your vehicle for leaks or torn CV boots. Follow this structured sequence to get it done efficiently.
- Warm up the engine: Run the car for three to five minutes to warm the oil so it drains completely and carries away suspended contaminants. Turn off the ignition, set the parking brake, and safely elevate the front end using hydraulic jacks and sturdy jack stands. Never crawl under a car supported only by a hydraulic jack.
- Locate and remove the drain plug: Slide underneath the front passenger side to find the oil pan. Place your drain pan directly beneath the drain plug. Use your 17mm socket to loosen the plug counterclockwise, then hand-spin it out while pulling it away quickly to keep oil off your fingers.
- Drain and inspect: Allow the oil to stream into the pan until it slows to a drip—usually about ten minutes. Inspect the old crush washer on the drain plug. If it's flattened or gouged, swap it out with a new one to prevent slow leaks. Wipe the drain hole clean.
- Remove the old oil filter: Locate the oil filter near the front of the engine block. Position your drain pan underneath it, as some residual oil will spill out when loosened. Turn the filter counterclockwise with a filter wrench if it's tight. Ensure the old rubber gasket comes off with the filter and doesn't stick to the engine mounting flange.
- Install the new filter: Dip a clean finger into fresh 0W-20 oil and smear a thin layer across the rubber gasket of the new filter. This ensures a proper seal and makes removal easier next time. Screw the filter on by hand until you feel the gasket seat firmly against the block, then turn it an additional three-quarters to one full turn. Do not over-tighten with a wrench.
- Reinstall the drain plug: Thread the drain plug back into the oil pan by hand to avoid cross-threading. Snug it down with the 17mm socket until the crush washer compresses fully.
- Fill with fresh oil: Remove the oil filler cap under the hood. Insert your clean funnel and pour in 4.0 quarts of 0W-20 synthetic oil. Reinstall the oil filler cap temporarily.
- Check levels and reset monitor: Start the engine and let it idle for 30 seconds while checking underneath for leaks around the plug and filter. Turn the car off, pull the dipstick, wipe it, reinsert it, and check the level. It should sit right at the upper dot. Top off slowly with the remaining half-quart until it hits the full mark. Finally, reset your maintenance minder via the steering wheel controls.
Common Mistakes to Avoid
Avoiding simple errors keeps your engine safe from costly damage.
- Double gasket retention: Leaving the old rubber gasket stuck to the engine block when installing a new filter causes an immediate, massive oil blowout upon startup. Always check the old filter face.
- Over-tightening the drain plug: The aluminum oil pan threads strip easily. Torque the drain plug firmly by hand rather than using a breaker bar.
- Running low on oil: Relying solely on mileage stickers without checking the dipstick every few thousand miles can lead to engine starvation, especially since modern direct-injection engines naturally consume small amounts of oil between changes.
Frequently Asked Questions
What happens if I accidentally put 5 quarts in my 2017 Acura ILX?
Adding an extra half-quart above the 4.5-quart capacity typically won't cause catastrophic damage, but overfilling creates excessive internal pressure. This causes the crankshaft to whip the oil into foam, reducing lubrication efficiency and leading to blown seals or rough idling. If you overfilled by a significant amount, drain a portion out using the plug or an extraction pump.
Can I use conventional oil in a 2017 Acura ILX?
Conventional oil breaks down faster under high operating temperatures and fails to meet Acura's strict anti-wear standards for this engine. Sticking to full synthetic 0W-20 guarantees optimal viscosity retention across freezing winter mornings and hot summer highway commutes.
How do I reset the oil life indicator on the dashboard?
Turn the ignition to the ON position without starting the engine. Use the multi-information display controls on your steering wheel to navigate to the "Maintenance" screen showing oil life percentage. Press and hold the Enter button until the display prompts you to reset, then select "Reset" to bring it back to 100 percent.
