The 2008 Acura TL typically requires synthetic engine oil with a viscosity of 5W-20 as the standard specification. In hot climates or under heavy-duty use, 5W-30 is commonly considered an acceptable alternative. The engine holds about 5.5 quarts of oil when a filter is replaced. Always verify the exact specification in your vehicle’s owner's manual or maintenance minder system.
Oil specification and viscosity
Understanding the recommended oil helps ensure proper engine protection and fuel efficiency. For most 2008 TL models, Acura specifies a 5W-20 viscosity, with 5W-30 acceptable in hotter environments or under more demanding driving conditions. Using the correct oil grade is important for cold-start protection and overall engine longevity.
Notes on oil grade and brand
Choose a high-quality engine oil that meets or exceeds the API requirements and Honda/Acura service standards. Synthetic oil is generally preferred for this vehicle, and it’s advisable to replace the oil filter at each oil change.
Before listing specific options, here are the common viscosity choices and when to use them:
- 5W-20 synthetic oil: The standard recommendation for most climates and driving patterns.
- 5W-30 synthetic oil: Acceptable in hot climates or for severe service (e.g., frequent heavy driving or towing).
- 0W-20 or 0W-30: Some markets or dealer recommendations may mention these in specific conditions; only use if your manual or dealer specifies them for your vehicle.
In practice, sticking with 5W-20 synthetic covers the majority of driving scenarios for the 2008 TL. Check your manual or with a dealer if you’re unsure about local climate or unusual operating conditions.
Oil capacity and maintenance timing
Knowing the oil capacity and service interval helps plan changes and keep the engine well-lubricated. The TL’s oil capacity is roughly 5.5 quarts with a filter change.
- Oil capacity: Approximately 5.5 quarts (with filter).
- Recommended change intervals: With synthetic oil, many owners follow the vehicle’s Maintenance Minder system, typically translating to intervals around 7,500 miles under normal conditions; shorter intervals (about 3,000–5,000 miles) may apply under severe service such as frequent short trips, extreme heat, or towing. Always rely on the Maintenance Minder and owner's manual for exact timing.
Maintenance Minder will indicate when an oil change is needed based on driving conditions and sensor data, so it’s best to use that system as the primary guide.
Practical tips for maintenance
To keep the engine running smoothly, perform oil changes using the recommended viscosity, replace the oil filter at each change, and use a high-quality filter designed for the Honda/Acura system. Keep a record of oil changes and follow the Maintenance Minder prompts to ensure optimal engine health.
Summary
For most 2008 Acura TL models, use synthetic oil with a viscosity of 5W-20 as the standard specification. If you live in a hot climate or expect heavy-duty use, 5W-30 is an acceptable alternative. The approximate oil capacity is 5.5 quarts with a new filter. Always consult the owner’s manual or your dealer for the exact grade and interval guidance, and rely on the Maintenance Minder system for precise change timing.
