How many quarts of oil does an Acura RDX take?
Most modern Acura RDX models with the 2.0-liter turbo engine take about 4.7 quarts of oil (with filter). Older RDX models equipped with the 3.5-liter V6 use about 5.5 quarts. Always consult the owner’s manual or the under-hood specification sticker for the exact figure for your year and configuration.
Oil capacity by engine and generation
The RDX has evolved from a V6 into a turbocharged four-cylinder in recent years, and oil capacity tracks that change. The figures below reflect common published capacities and include the oil filter in the total. Variations can occur by model year or revisions, so always verify your exact spec.
Current-generation RDX: 2.0L turbo
To help owners quickly identify the correct figure, the current-generation uses the turbocharged 2.0-liter engine. The typical capacity for this configuration is:
Before listing the capacity, note that this section covers the modern RDX.
- Oil capacity (2.0L turbo, modern RDX): 4.7 quarts (approximately 4.4 liters) including the oil filter.
Concluding: This is the standard oil capacity for most current RDX models with the 2.0L turbo; always check the dipstick and owner’s manual when performing an oil change.
Older generations: 3.5L V6
Earlier RDX models used a 3.5-liter V6, which requires more oil. The typical capacity for this engine configuration is:
Before listing the capacity, note that this section covers pre-2013 and early RDX models.
- Oil capacity (3.5L V6, older RDX): 5.5 quarts (with filter).
Concluding: This figure applies to the older RDX generations; if you own a newer model, verify the 2.0L turbo specification instead.
How to confirm your exact capacity for your vehicle
Because capacity can vary by year, trim, and changes in revision, use these steps to confirm the precise number for your car:
- Check the owner’s manual under Specifications or Maintenance for the official oil capacity.
- Look for an under-hood label on the engine cover or radiator support that lists oil capacity and grade.
- If you’re unsure, contact a local Acura dealer with your VIN to pull the exact specification for your exact model year.
Concluding: Knowing your precise figure ensures you buy the right amount of oil and maintain proper level and pressure for optimal engine health.
Oil type and general maintenance notes: For recent 2.0L turbo RDX models, Acura commonly recommends full-synthetic 0W-20 oil. Older 3.5L V6 engines typically used synthetic 5W-30 (or as specified in the manual). Always use the grade and viscosity specified for your year and engine by Acura.
Summary
In short, the oil capacity of an Acura RDX depends on the engine. Modern RDX models with the 2.0L turbo typically require about 4.7 quarts (with filter), while older RDX versions with the 3.5L V6 use about 5.5 quarts. Always verify the exact capacity for your specific year and drivetrain in the owner’s manual or via the dealer using your VIN, and use the recommended oil grade for best results.
