What type of oil does my 2008 Acura MDX take?

The 2008 Acura MDX requires 5W-20 full-synthetic engine oil, with about 5 quarts needed per oil change. Use oil that meets the appropriate API/ILSAC specifications and verify details in the owner's manual or with a dealer if you’re unsure.


Recommended oil type and viscosity


The 2008 MDX, powered by the 3.5-liter V6, is designed to run on 5W-20 viscosity oil. Acura recommends synthetic oil for optimal performance, efficiency, and emissions control. If a full synthetic isn’t available, a high-quality synthetic-blend that meets the same API/ILSAC specs is acceptable.


Before you choose your oil, keep these guidelines in mind:



  • Viscosity: 5W-20 is the standard recommendation for normal operation across a wide range of climates.

  • Oil type: Full synthetic is preferred; synthetic blends are acceptable if needed.

  • Specifications: The oil should meet API service designation SM (or higher) and ILSAC GF-4 or GF-5. Many modern oils labeled SN/SP are compatible, but always verify the label and the manual.



In practical terms, sticking with 5W-20 synthetic oil that meets the relevant API/ILSAC specs will keep the 2008 MDX running smoothly and help maintain the engine’s performance and efficiency.


How to confirm the exact requirement for your vehicle


Because variations can occur by region or production batch, confirm the exact grade and capacity in your owner's manual. If you no longer have the manual, you can download a PDF from Acura/Honda’s official site or consult your dealer for the recommended grade, capacity, and any climate-specific notes.



  • Check the engine oil section of the manual for the official viscosity and specification.

  • Inspect the oil filler cap on the engine; it often lists the recommended viscosity (commonly 5W-20).

  • Choose an oil that explicitly meets API/ILSAC standards, and ensure it is labeled for 5W-20.

  • Always replace the oil filter during a drain and fill and dispose of used oil responsibly.


Oil-change intervals can vary with driving conditions. Severe driving (extensive idling, short trips, extreme temperatures, or towing) may warrant more frequent changes.


Additional notes for maintenance and driving conditions


If you’re unsure about your driving conditions, err on the side of caution and follow the maintenance minder or manual guidelines. For many owners, synthetic oil can extend intervals, but regional and usage differences apply.


Summary



  • Oil type and viscosity: 5W-20 full-synthetic oil is recommended for the 2008 Acura MDX.

  • Oil capacity: About 5 quarts with the filter per change.

  • Specifications: Look for API service designation SM (or higher) and ILSAC GF-4 or GF-5 (or newer compatible specifications).

  • Verification: Always reference the owner's manual or consult a dealer to confirm exact requirements for your vehicle and driving conditions.
