The TLX uses fully synthetic 0W-20 engine oil for both the 2.4-liter i-VTEC four-cylinder and the 3.5-liter V6 models. Use oil that meets API SN or newer and ILSAC GF-5 or newer, and pair it with a genuine Acura/Honda oil filter.
Oil Type and Viscosity
Both available engines in the 2015 TLX share the same low-viscosity, high-performance oil specification. Selecting the right oil helps with cold-start protection, fuel efficiency, and long-term engine durability.
Two engines, one oil standard
- Viscosity: 0W-20
- Oil type: Full synthetic engine oil
- Specifications: API SN or newer; ILSAC GF-5 or newer
- Applicability: Suitable for both 2.4L i-VTEC and 3.5L V6 TLX engines
Using the correct oil ensures optimal performance and helps preserve warranty coverage. Always confirm the exact spec in the owner's manual or with a dealer if you’re unsure.
Maintenance and Change Intervals
Oil-change timing is guided by Acura’s Maintenance Minder system, which considers driving conditions and mileage. In typical use, expect changes within a broad window that commonly ranges from about 7,500 to 10,000 miles, but follow the Minder’s prompts for the exact interval. Always replace the oil filter at each oil change and recheck the oil level after refilling.
- Follow the Maintenance Minder for the precise interval
- Use a genuine oil filter or OEM-equivalent
- Ensure the oil level is within the proper range after service
Adhering to these guidelines helps maintain engine health and keeps the vehicle operating as designed.
Additional Considerations
Beyond the oil itself, consider using OEM-approved or high-grade third-party oils that meet the same specifications, and verify the service recommendations with your local Acura dealership, especially if you drive in extreme climates or engage in heavy driving conditions.
Summary
For a 2015 Acura TLX, the recommended oil is full synthetic 0W-20 meeting API SN or newer and ILSAC GF-5 or newer, applicable to both the 2.4L and 3.5L engines. Use a genuine Acura/Honda oil filter, and rely on the Maintenance Minder to time oil changes. When in doubt, consult the owner's manual or your local dealer for guidance.
