Oil Maintenance and Service Tips
Checking Oil Level
Check engine oil level regularly using the dipstick with the engine off and on level ground. The oil level should be between the minimum and maximum marks. Low oil levels can cause engine damage while overfilling can lead to increased pressure and potential seal leaks.
Oil Filter Replacement
Always replace the oil filter during every oil change to ensure proper filtration of contaminants. OEM filters such as 15400-PLM-A02 and 15400-RTA-003 meet Acura specifications for fit and filtration efficiency. Aftermarket equivalents from Mobil 1, K&N, and ECOGARD are also available.
Oil Change Intervals
The Acura Maintenance Minder system monitors driving conditions and calculates optimal oil change intervals. Under normal driving conditions, synthetic oil changes are typically required every 7,500 to 10,000 miles. Severe driving conditions such as frequent short trips, extreme temperatures, or stop-and-go traffic may require more frequent service intervals of 5,000 miles.
Oil Drain Plug Torque
Proper torque specification for the oil drain plug is 29 lb-ft (39 N·m). Over-tightening can strip threads in the oil pan while under-tightening may cause leaks. Always use a torque wrench for accurate installation.
Driving Conditions Comparison
| Condition Type | Oil Change Interval | Driving Examples |
|---|---|---|
| Normal Driving | 7,500-10,000 miles | Highway commuting, moderate climate |
| Severe Driving | 5,000-7,500 miles | Short trips, extreme heat or cold, towing, dusty conditions |
Frequently Asked Questions
What kind of oil does an Acura ILX use?
The Acura ILX uses SAE 0W-20 full synthetic motor oil for all engine variants. Full synthetic oil provides superior protection against thermal breakdown, better cold-start performance, and extended drain intervals compared to conventional oil.
How much oil does an Acura ILX take?
The Acura ILX oil capacity varies by engine size. The 1.5L hybrid takes 3.8 quarts, the 2.0L engine requires 3.9 quarts, and the 2.4L engine needs 4.4 quarts with filter replacement. Always verify your specific engine type before adding oil.
What is the recommended oil type for an Acura ILX?
Acura recommends full synthetic 0W-20 motor oil meeting API certification standards for the ILX. Synthetic oil maintains viscosity across a wider temperature range and offers better engine protection under various driving conditions than conventional or synthetic blend oils.
What is the oil change interval for an Acura ILX?
The recommended oil change interval for an Acura ILX is every 7,500 to 10,000 miles when using full synthetic oil under normal driving conditions. The Maintenance Minder system calculates the optimal interval based on actual driving habits and environmental factors.
Can I use 5W-20 oil instead of 0W-20 in my Acura ILX?
While 5W-20 may work in warmer climates, 0W-20 is specifically engineered for the ILX to optimize fuel efficiency and cold-start protection. Using the manufacturer-specified 0W-20 viscosity ensures proper lubrication and maintains warranty coverage.
What oil filter does an Acura ILX use?
The Acura ILX uses OEM oil filter part numbers 15400-PLM-A02 or 15400-RTA-003. Compatible aftermarket filters include Mobil 1 M1-110A, K&N HP-1004, and ECOGARD S4610. Always ensure the filter meets Acura specifications for proper fitment and filtration.
Conclusion
The Acura ILX requires different oil capacities depending on the engine variant, ranging from 3.8 quarts for the 1.5L hybrid to 4.4 quarts for the 2.4L engine. All models use 0W-20 full synthetic oil to ensure optimal engine protection and fuel efficiency. Following manufacturer-specified oil capacity, viscosity, and change intervals is essential for maintaining engine longevity and performance.
Using genuine Acura oil filters and high-quality synthetic oil helps protect internal engine components from wear and thermal breakdown. Regular oil maintenance according to the Maintenance Minder system recommendations ensures your Acura ILX continues to deliver reliable performance and efficiency throughout its service life.
