Complete Guide to Acura ILX Engine Oil Capacity (2013-2022)
Professional maintenance guide with interactive calculator, specifications, and expert recommendations for all Acura ILX models
Proper engine oil maintenance is critical for the longevity and performance of your Acura ILX. Using the correct oil capacity ensures optimal lubrication, cooling, and protection for your engine’s internal components. This comprehensive guide provides detailed specifications for every Acura ILX model year from 2013 to 2022, including an interactive calculator to determine exact oil requirements based on your specific vehicle configuration.
Understanding Engine Oil Capacity Specifications
Engine oil capacity refers to the total volume of oil required to properly lubricate your Acura ILX’s engine. This measurement varies based on several factors including engine displacement, model year, and whether you’re performing a standard oil change or complete engine rebuild. Using incorrect oil quantities can lead to serious engine damage, reduced performance, and voided warranties.
Oil Change Capacity vs. Dry Fill Capacity
The automotive industry recognizes two primary capacity measurements: oil change capacity (the amount needed during routine maintenance) and dry fill capacity (required after engine rebuilds). Oil change capacity is typically 0.5-1.0 quarts less than dry fill capacity due to residual oil remaining in the engine’s galleries and components.
Overfilling your Acura ILX with engine oil can cause foaming, reduced lubrication, and potential engine damage. Underfilling leads to inadequate lubrication and increased wear. Always use the dipstick to verify oil level after changes, and never exceed the manufacturer’s recommended capacity.
Acura ILX Oil Capacity Specifications by Generation
The Acura ILX underwent significant changes between its first generation (2013-2015) and second generation (2016-2022). These changes affected engine options, oil capacities, and recommended maintenance procedures.
First Generation (2013-2015) Specifications
The initial Acura ILX models offered two engine options: a 2.0L inline-4 cylinder and a more powerful 2.4L inline-4 cylinder. These engines represented Honda’s engineering excellence but required different maintenance approaches.
| Model Years | Engine Type | Oil Change Capacity | Dry Fill Capacity | Recommended Oil Type | Oil Filter Part # |
|---|---|---|---|---|---|
| 2013-2015 | 2.0L i-VTEC 4-cylinder | 4.2 quarts (3.97 liters) | 4.8 quarts (4.54 liters) | 0W-20 Synthetic | 15400-PLM-A02 |
| 2013-2015 | 2.4L i-VTEC 4-cylinder | 4.4 quarts (4.16 liters) | 5.0 quarts (4.73 liters) | 0W-20 Synthetic | 15400-PLM-A02 |
Second Generation (2016-2022) Specifications
For the 2016 model year, Acura streamlined the ILX to feature only the 2.4L engine, which offered improved performance and efficiency. This generation maintained consistent oil capacity requirements throughout its production run.
| Model Years | Engine Type | Oil Change Capacity | Dry Fill Capacity | Recommended Oil Type | Oil Filter Part # |
|---|---|---|---|---|---|
| 2016-2022 | 2.4L i-VTEC 4-cylinder | 4.5 quarts (4.26 liters) | 5.1 quarts (4.83 liters) | 0W-20 Synthetic | 15400-PLM-A02 |
Professional Oil Change Procedure for Acura ILX
Following proper oil change procedures ensures your Acura ILX receives optimal protection and maintains peak performance. This step-by-step guide combines manufacturer recommendations with professional technician insights.
Step-by-Step Maintenance Guide
Begin by warming the engine to operating temperature (approximately 10 minutes of driving), which thins the oil for complete drainage. Park on a level surface and engage the parking brake. Remove the oil fill cap to relieve internal pressure, then locate and remove the under-engine drain plug using a 17mm socket. Allow complete drainage for at least 15 minutes to ensure all contaminated oil exits the system.
Replace the drain plug washer with each oil change to prevent leaks. Torque the drain plug to 30 ft-lbs (41 N·m) using a calibrated torque wrench. Over-tightening can strip the aluminum oil pan threads, leading to expensive repairs.
Oil Filter Replacement Protocol
The Acura ILX uses a cartridge-style oil filter located on the engine’s top front. Remove the filter cover using an oil filter wrench, then extract the old filter element. Clean the filter housing thoroughly, install the new filter element with a fresh O-ring lubricated with clean oil, and torque the cover to 18 ft-lbs (24 N·m).
Technical Specifications and Fluid Requirements
Beyond basic capacity measurements, several technical factors influence your Acura ILX’s oil requirements and maintenance schedule.
Viscosity Specifications and Standards
Acura specifies 0W-20 viscosity oil meeting API SN, SN Plus, or SP certification for all ILX models. This low-viscosity oil provides optimal fuel economy while maintaining protective film strength. The “0W” rating indicates excellent cold-start performance, flowing readily at temperatures as low as -40°F (-40°C).
Oil Quality Standards and Certifications
Ensure your oil carries the ILSAC GF-6 certification mark, indicating it meets the latest industry standards for deposit control, wear protection, and fuel economy retention. Honda/Acura Genuine Oil or equivalent premium synthetic blends provide the best protection for your ILX’s precision-engineered components.
