The 2015 Acura TLX uses 0W-20 synthetic oil for both of its available engines. This lightweight grade is specified to support the car’s performance and fuel efficiency, with the exact amount varying by engine and configuration.
In the 2015 TLX lineup, buyers could choose between a 2.4-liter four-cylinder engine or a 3.5-liter V6. Acura specifies the same 0W-20 synthetic oil for both options, but it’s still important to confirm the exact capacity and any regional recommendations in the owner’s manual or with an Acura dealer.
Engine options and oil specification
Below is a quick breakdown of the TLX’s two available powertrains and their oil requirements.
- 2.4-liter inline-4 engine (base TLX) — 0W-20 synthetic oil, meeting ILSAC GF-5 (or newer) specifications.
- 3.5-liter V6 engine (premium/SH-AWD variants) — 0W-20 synthetic oil, meeting ILSAC GF-5 (or newer) specifications.
Both engine choices in the 2015 TLX share the same recommended oil grade, but always verify the exact capacity and any regional or model-year updates in your owner’s manual or with an Acura service adviser.
Maintenance and best practices
To keep the TLX running smoothly, follow the maintenance minder recommendations and use a high-quality synthetic 0W-20 oil that meets the ILSAC GF-5 (or newer) standard. If you drive under severe conditions or in extreme temperatures, consult the manual for any adjustments to the oil change interval or viscosity guidance.
Summary
For the 2015 Acura TLX, the recommended oil is 0W-20 synthetic for both engine options. Always use oil that meets ILSAC GF-5 or newer, adhere to the maintenance minder schedule, and refer to the owner's manual or a dealer for capacity specifics and any regional nuances.
