What kind of oil goes in a 2012 Acura TSX?

The 2012 Acura TSX requires synthetic 5W-20 engine oil, typically about 4.5 quarts with a filter, and it should be changed on a schedule that aligns with synthetic oil recommendations. Use oil that meets API SN or newer and ILSAC GF-5 or newer for best protection.

Oil type and grade

To keep the TSX running smoothly and to maintain warranty protections, use a fully synthetic 5W-20 grade that meets API SN (or newer) and ILSAC GF-5 (or newer). Some colder climates may reference lighter grades, but 5W-20 is the standard specification for most 2012 TSX models. Always verify with the owner’s manual or dealer if you’re unsure.

Here are the oil specifications that match the factory recommendations for the 2012 TSX.



• 5W-20 synthetic engine oil (fully synthetic)


• API SN (or newer) certification


• ILSAC GF-5 (or newer) certification


• Honda/Acura-approved formulations or equivalent high-quality brands

Using the correct oil grade and spec helps maximize lubrication, fuel economy, and engine wear protection. Stick to products that meet these specifications as outlined in the manual.

Capacity and service guidelines

Understanding the fill amount and maintenance cadence helps prevent underfilling and ensures consistent performance over the life of the engine.

• Oil capacity: Approximately 4.5 quarts (4.3 liters) with the oil filter

Maintenance intervals depend on the oil type you use. The vehicle is designed to run on synthetic oil with longer intervals, while conventional oil requires more frequent changes.

• Change interval with synthetic oil: about every 7,500 miles (12 months), whichever comes first


• Change interval with conventional oil: about every 3,000–5,000 miles (6 months), whichever comes first

Always consult the owner's manual and follow the maintenance schedule provided by your dealer. Regularly checking the oil level between changes is also advised.

Practical considerations

Choosing a brand and ensuring compatibility

Opt for reputable brands that meet the API SN and ILSAC GF-5 specifications. While Honda/Acura-branded lubricants are a safe choice, many major brands offer fully synthetic oils that satisfy the same standards and are suitable for the TSX as long as they carry the correct certifications.

DIY oil changes vs. professional service

Oil changes can be performed at home with the right tools, but if you’re unsure, a certified technician or dealership can ensure the correct oil quantity, filter replacement, and proper disposal. Don’t forget to reset maintenance reminders after completing an oil change.

Summary

For a 2012 Acura TSX, the standard oil is synthetic 5W-20 that meets API SN and ILSAC GF-5, with an approximate capacity of 4.5 quarts (plus the filter). Typical change intervals are 7,500 miles with synthetic oil or 3,000–5,000 miles with conventional oil. Always verify the exact specification in the owner’s manual and follow the recommended maintenance schedule.

What oil is thicker, 5w20 or 10w40?

They test oil at a lower temperature to determine the first number (SAE 0W, 5W, 10W, etc.). They test it at a higher temperature to determine the second number (SAE 30, 40, 50, etc.). For instance, SAE 5W-30 oil flows better at colder temperatures than 10W-40 oil. But, SAE 10W-40 oil is thicker.

Can I use 5W-30 engine oil?

5W-30 oil can be used in petrol and diesel engines in most cars, motorcycles, trucks and SUVs. If your vehicle is often used for long journeys carrying heavy loads, consider exploring a different oil category better suited to your vehicle's specific needs.
