What kind of oil does a 2018 Acura TLX take?
The 2018 Acura TLX requires 0W-20 synthetic motor oil.
In 2018, the TLX offered two engine choices—the 2.4-liter inline-four and the 3.5-liter V6. For both engines, Acura specifies 0W-20 full-synthetic oil that meets API SN (or newer) and ILSAC GF-5 or GF-6 specifications. Always verify the exact requirement on the oil cap or in the owner’s manual if you’re unsure.
Oil specifications for the 2018 TLX
To keep the TLX running smoothly, note the following key oil specifications and guidelines:
- Viscosity: 0W-20 (full synthetic) for optimal lubrication and efficiency.
- Oil type: Full synthetic motor oil.
- Certifications: API SN or newer, ILSAC GF-5 or GF-6 compliant oil.
- Maintenance interval: Typical oil change every 7,500 miles or 12 months under normal driving; more frequent changes under severe driving conditions.
Bottom line: Use 0W-20 synthetic oil that meets API and ILSAC specifications, and follow the maintenance schedule outlined in the owner’s manual.
Engine-specific nuances
Both the 2.4L I-4 and the 3.5L V6 in the 2018 TLX share the same viscosity requirement (0W-20). The main differences you’ll encounter are in engine capacity and service intervals, not the recommended oil grade itself. Always confirm any engine-specific notes in the manual or on the oil cap.
Maintenance tips and best practices
When changing the oil in your TLX, consider these practical tips to ensure a proper fill and long engine life:
- Use a genuine Acura/Honda-approved 0W-20 full-synthetic motor oil that meets the stated API/GF specs.
- Replace the oil filter with every oil change and ensure the drain plug is torqued to the specifications in the manual.
- Check oil level with the engine cold and on level ground; top up to the full mark if needed.
- Adhere to the recommended interval: typically 7,500 miles or 12 months under normal driving, with more frequent changes under severe driving conditions (short trips, extreme temperatures, heavy traffic, towing).
If you’re unsure about the exact capacity for your specific engine, or if you’re using an oil brand not listed above, consult the owner’s manual or contact an Acura service professional for guidance.
Summary
For a 2018 Acura TLX, the recommended oil is 0W-20 synthetic, suitable for both the 2.4L inline-four and the 3.5L V6. It should meet API SN or newer and ILSAC GF-5 or GF-6 standards. Follow the manufacturer’s maintenance schedule and replace the oil and filter at the recommended intervals, adjusting for driving conditions. When in doubt, refer to the owner’s manual for the exact specifications and capacity related to your engine variant.
