The Acura TL primarily uses synthetic engine oil, with the exact grade tied to the model year: older TLs typically require 5W-30, while many newer TLs specify 5W-20. Always verify the precise specification on the under-hood sticker or in the owner's manual for your exact year and engine.
Oil specifications by generation
First generation TL (1999–2003)
The original TL used a 3.2-liter V6 and generally called for 5W-30 synthetic or synthetic-blend oil. The typical oil capacity with a filter is around 4.5 quarts. Use a reputable brand that meets current API/ILSAC standards.
Recommended oil details for this generation:
- Grade: 5W-30 (synthetic or synthetic blend preferred)
- Capacity: approximately 4.5 quarts with a filter
- Notes: Synthetic oil provides better protection and is widely supported by Acura/Honda service manuals
Conclusion for this generation: For the first-generation TL, 5W-30 synthetic is the standard recommendation; always confirm exact specs for your specific year and climate.
Second generation TL (2004–2008)
The 2004–2008 TL continued with the 3.2-liter V6 and generally recommended 5W-30 oil, with a similar capacity to the first generation (roughly 4.5 quarts with filter). Synthetic or synthetic-blend oil is advised.
Recommended oil details for this generation:
- Grade: 5W-30 (synthetic or synthetic blend)
- Capacity: about 4.5 quarts with a filter
- Notes: Use a high-quality oil that meets current API/ILSAC standards; synthetic is preferred for protection and longevity
Conclusion for this generation: 5W-30 synthetic is the standard recommendation; check your manual for any climate-specific guidance.
Third generation TL (2009–2014)
The 2009–2014 TL switched to a 3.5-liter V6, and many manuals specify 5W-20 as the standard grade, with a larger oil capacity (approximately 5 quarts with a filter). Synthetic oil remains the preferred option.
Recommended oil details for this generation:
- Grade: 5W-20 (synthetic or synthetic blend)
- Capacity: around 5 quarts with a filter
- Notes: Use oil that meets current API/ILSAC standards; synthetic is recommended for optimal protection and fuel economy
Conclusion for this generation: For 2009–2014 TLs, follow the 5W-20 specification; verify the exact grade and capacity in your manual or on the fill cap, especially if you live in extreme climates.
General tips for choosing oil
Before choosing oil, keep these considerations in mind to ensure you’re using the right product for your TL:
- Use synthetic oil (full synthetic or synthetic blend) for better protection and longer drain intervals
- Follow the grade specified for your year (5W-30 for older generations, 5W-20 for newer generation TLs)
- Ensure the oil meets current API/ILSAC standards (e.g., API SN or newer, ILSAC GF-5 or newer)
Conclusion: Across all generations, synthetic oil that matches the manufacturer’s grade is the safest choice. When in doubt, consult the owner's manual or your Acura dealer for the exact specification for your vehicle.
Summary
In short, the Acura TL’s oil needs depend on the model year: 1999–2008 TLs commonly use 5W-30, while 2009–2014 TLs typically require 5W-20. Synthetic oil is preferred for all generations, and you should always verify the precise grade and capacity on the oil fill cap or in the owner's manual for your specific vehicle and climate.
