Complete Oil Specifications
Your 2022 Acura TLX with the 2.0T K20C4 engine requires 0W-20 full synthetic oil meeting API SP / ILSAC GF-6A. The K20C4 is Honda/Acura’s turbocharged four-cylinder — a direct-injection, VTEC Turbo engine producing 272 horsepower in the TLX’s base configuration and optimized for both performance and efficiency.
Capacity Note: 5.1 quarts is the correct capacity for a routine drain-and-fill with a new filter. Do not use 5.7 quarts — that figure applies to a dry engine assembly from the factory. Overfilling will cause foaming and potential oil seal damage.

Why 0W-20 for the VTEC Turbo K20C4
The K20C4 features Honda’s VTEC (Variable Valve Timing and Lift Electronic Control) system combined with a twin-scroll turbocharger. The VTEC mechanism uses oil pressure to actuate rocker arm geometry changes — switching between low-lift and high-lift cam profiles. This hydraulic system requires fast oil pressurization at startup, and 0W-20’s low cold-start viscosity ensures the VTEC system activates correctly from the first throttle input. The turbocharger’s bearings also benefit from the rapid oil flow.
Using incorrect oil will:
- ❌ Delay VTEC activation, causing hesitation and abnormal valve timing at cold start
- ❌ Increase turbo shaft wear if heavier viscosity slows oil delivery
- ❌ Reduce fuel economy — the K20C4’s EPA rating is partly achieved through 0W-20 friction reduction

- Use SH-AWD Sport mode or performance driving regularly
Installation Details
Drain Plug Torque: 30 ft-lbs
Always replace the drain plug washer. Acura uses a soft aluminum washer that deforms to seal — reusing it risks a slow leak.

Pro Tip: The K20C4 oil filter is positioned on the front of the engine block and is easy to access from above. Hand-tighten the filter, then turn an additional 3/4 turn — do not use a wrench to install.
FAQs
What oil does a 2022 Acura TLX take?
0W-20 full synthetic meeting API SP / ILSAC GF-6A.
How many quarts does the TLX 2.0T need?
5.1 quarts with a new filter for a standard drain-and-fill. Do not fill to 5.7 quarts — that is the dry-engine figure only.
Can I use 5W-30 for better turbo protection?
No. Acura specifies 0W-20 for the K20C4. If turbo longevity is a concern, change the oil more frequently rather than using a heavier grade.
Is synthetic oil required?
Yes. Full synthetic only to meet API SP / GF-6A requirements.
How often should I change the oil?
Every 7500 miles for normal driving. Acura’s Maintenance Minder system will also calculate the interval based on your driving patterns.
