๐ก๏ธ Viscosity & Climate Dynamics
- Factory Recommendation: Engineers specify 0W-20 Full Synthetic for all operating temperatures on the 2016 Acura ILX (Also see guides for 2015 Acura ILX and 2017 Acura ILX)., matching platform siblings like the 2016 Acura MDX.
- Sub-Zero Cold Starts (<32ยฐF / 0ยฐC): Multi-grade synthetic formulation ensures instant oil pressure to hydraulic timing chain tensioners and camshaft journals within milliseconds of cranking.
- High-Temperature Shear (>100ยฐC): High HTHS thermal stability maintains a resilient hydrodynamic barrier on crankshaft rod bearings under heavy acceleration or towing.
- Emergency Top-Ups: If required, a heavier viscosity can be used for emergency top-up, but return to 0W-20 Full Synthetic at the next scheduled oil service.
โ๏ธ Sub-Zero Ambient Starts (<32ยฐF)
Rapid multi-grade flow prevents dry metal-on-metal friction within milliseconds of cranking.
โ๏ธ High-Temperature Shear (>100ยฐC)
Maintains hydrodynamic oil film strength between crankshaft rod journals under high loads.
๐ก๏ธ VVT & Camshaft Protection
Prevents varnish deposits on variable valve timing solenoids and protects timing chains.
๐งช Oil Formulation: Full Synthetic vs. Synthetic Blend
- Mandatory Specification: Full synthetic meeting API SP / ILSAC GF-6 is required for the 2016 Acura ILX.
- LSPI & Turbo Protection: Advanced additive packages prevent destructive Low-Speed Pre-Ignition (LSPI) and timing chain elongation in modern high-compression engines.
- High Thermal Resistance: Group III+ and PAO synthetic base stocks resist NOACK volatility oil burn-off under extreme turbocharger heat.
- Conventional Oil Risk: Non-approved conventional oils break down rapidly, causing sludge deposits in variable valve timing (VVT) solenoids and oil pickup screens.
๐ฌ Oil Filtration & Bypass Valve Dynamics
- Factory OEM Part: Genuine filter is
15400-PLM-A02(Premium aftermarket equivalents: Mobil 1M1-110A, Wix57356). - Calibrated Bypass Valve: Features an engineered relief valve that prevents oil starvation during cold morning starts.
- Silicone Anti-Drainback: Prevents dry-start metal-on-metal friction by retaining oil inside the filter canister when the engine is shut off.
- Micron Efficiency: Synthetic blend filter media captures particulate contaminants down to 20 microns without restricting flow rate.
๐ Maintenance Service Intervals
๐ข Normal Driving Interval
10000 Miles / 12 Months
Standard highway cruising and daily commuter driving.
๐ก Severe Driving Interval
5000 Miles / 6 Months
Short trips under 5 miles, stop-and-go city traffic, dusty unpaved roads, or heavy towing.
โ ๏ธ Troubleshooting & Common Problems
- Crush Washer Replacement: Always install a new 14mm crush washer to prevent persistent slow pan leaks under high crankcase pressure.
- Avoid Overfilling: Never fill beyond the upper dipstick dot; excess oil causes crankshaft whipping, aerated foam, and reduced oil pump pressure.
- Low Oil Pressure Warning: If the instrument cluster oil light illuminates, stop driving immediately to avoid severe bearing seizure.
๐ ๏ธ Step-by-Step DIY Oil Change Walkthrough
- 1Warm-Up & Elevate: Run engine for 3โ5 minutes, park on level surface, set emergency brake, and securely lift on jack stands or ramps.
- 2Locate the engine oil pan underbody, place an oil catch basin directly beneath, and use a 17mm socket or wrench to safely loosen and remove the oil drain plug.
- 3Unscrew the oil filter housing or canister using an oil filter wrench. Pre-lubricate the new 15400-PLM-A02 rubber O-ring with fresh engine oil, install, and hand-tighten until snug plus 3/4 turn.
- 4Clean the drain plug sealing surface, install a new OEM crush washer, and torque the drain bolt precisely to 30 lb-ft (41 Nm) to ensure zero oil pan thread damage or leaks.
- 5Lower the vehicle to level ground, pour in exactly 4.4 Quarts (4.2 L) of API-certified 0W-20 Full Synthetic engine oil via the top valve cover filler neck, reinstall cap, and run engine for 60 seconds.
- 6Verify Level & Leaks: Idle engine for 60 seconds, check for leaks underneath, shut off, wait 5 minutes, and verify dipstick level is at the top mark.

โ Frequently Asked Questions
How many quarts of oil does a 2016 Acura ILX take?
With a new filter change, the 2016 Acura ILX base engine configuration takes exactly 4.4 Quarts (4.2 Liters). Always recheck the dipstick on level pavement after a 2-minute warmup.
What oil type and viscosity grade is recommended for the 2016 Acura ILX?
The factory recommended viscosity grade for the 2016 Acura ILX is 0W-20 Full Synthetic (API SP / ILSAC GF-6 certified full synthetic oil).
What is the oil pan drain plug torque specification for a 2016 Acura ILX?
The factory OEM oil filter part number is 15400-PLM-A02. Compatible aftermarket filters include Mobil 1 (M1-110A) and Wix (57356).
What is the OEM oil filter part number for the 2016 Acura ILX?
The genuine OEM factory oil filter is part number 15400-PLM-A02. Equivalent premium aftermarket filters include Mobil 1 M1-110A and Wix 57356.
Can I use 5W-30 or 5W-20 instead of 0W-20 in my 2016 Acura ILX?
Using a heavier viscosity oil like 5W-30 when 0W-20 or 0W-16 is specified increases hydrodynamic drag, reduces cold-start lubrication speed, and may slightly reduce fuel economy. In emergencies, heavier oil can be used to top off, but it should be replaced with the factory 0W-20 Full Synthetic at the next scheduled oil change.
How often should you change the oil in a 2016 Acura ILX?
Under normal highway and commuter driving conditions with full synthetic oil, change the oil every 7,500 to 10,000 miles or 12 months. Under severe driving cycles (frequent trips under 5 miles, stop-and-go city driving, dusty unpaved roads, or heavy towing), change the oil every 5,000 miles or 6 months.
How do you reset the oil life light / maintenance minder on a 2016 Acura ILX?
Turn the ignition to ON without starting the engine, navigate to the Maintenance/Oil Life screen using the steering wheel controls or odometer button, hold down the reset button for 5-10 seconds until the display flashes, and confirm reset to 100%.
What happens if you overfill the engine oil on a 2016 Acura ILX?
Overfilling causes the rotating crankshaft to whip the excess oil in the oil pan into aerated foam. Aerated oil cannot be properly pumped by the oil pump, leading to oil starvation, hydraulic lifter clatter, elevated crankcase pressure, blown valve cover/crankshaft seals, and spark plug fouling.
