The 2008 Acura RDX typically uses 5W-30 full-synthetic motor oil, with an oil capacity of about 4.5 quarts including the filter. Always verify the exact specification in your owner's manual or with a dealer, as regional variations or aftermarket modifications can affect the requirement.
Oil type and specifications
Understanding the right oil for this turbocharged engine helps protect performance across seasons and driving styles. The guidance below reflects common factory recommendations for the 2008 RDX.
- Viscosity: 5W-30
- Oil type: Full synthetic preferred; high-quality synthetic blend acceptable if a full synthetic is not available
- Capacity: Approximately 4.5 quarts with the oil filter
- Change interval: Typically every 5,000–7,500 miles under normal driving conditions when using synthetic oil

Sticking to these guidelines helps maintain turbocharger efficiency and overall engine longevity. Always consult the owner's manual for your exact VIN and regional recommendations.
Choosing the right brand and how to verify the spec
Not all oils labeled 5W-30 will meet Honda/Acura standards. To ensure compatibility with the RDX’s engine tolerances, select an oil that explicitly meets the manufacturer’s specifications and is labeled as full synthetic.
Brand selection and specification verification
Follow these steps to pick the right oil and avoid compatibility issues:
- Choose a reputable brand that offers a 5W-30 full-synthetic oil
- Ensure the oil is labeled to meet Honda/Acura specifications listed in your manual
- Confirm the viscosity is 5W-30 at ambient temperatures and suitable for turbocharged engines
- Pair the oil with a compatible filter designed for the RDX’s oil system
- Check local availability and price, and consider dealer or certified shop guidance for VIN-specific advice
When in doubt, rely on the official service resources for a precise recommendation tied to your vehicle’s market and configuration.
