What oil is best for an Acura TSX?
The best oil for most Acura TSX models is a full-synthetic motor oil with a viscosity of 5W-20 (and 0W-20 in some years or climates), but always verify the exact specification in your owner's manual. Synthetic oils offer better protection and longer service intervals, which suits the TSX’s K-series engines.
Understanding the TSX oil needs
Acura TSX models span a few years with slightly different engine calibrations. The recommended viscosity and oil specification are largely determined by climate, engine variant, and maintenance intervals. In practice, most TSX owners stick with a light synthetic oil that flows quickly during cold starts while maintaining adequate film strength in heat and under load. Always cross-check the manual for your exact year and engine code to be sure.
What follows are common guidelines that apply to the TSX across model years, with notes on year-by-year differences and climate considerations.
- Viscosity options commonly used: 0W-20, 5W-20, and, in some cases where the manual permits it, 5W-30. The exact choice depends on your model year and climate.
- All options should be full-synthetic to maximize protection and fuel economy, especially under cold starts and hot ambient conditions.
- Oil that meets the appropriate standards (ILSAC and API) is essential; avoid off-spec blends that don’t meet the engine’s requirements.
In short, the right viscosity is dictated by your specific TSX version and environment, so confirm the factory recommendation for your vehicle before committing to a viscosity.
Oil types and standards to look for
Choosing an oil that meets the correct performance standards ensures compatibility with the TSX’s engine and its lubrication system. The following guidelines help you pick a compliant product.
- Choose a full-synthetic motor oil rather than conventional oil for improved protection, longer intervals, and better cold-weather starting.
- Look for oils that meet ILSAC GF-5 or GF-6 specifications, and API certification (e.g., API SN or newer). These standards ensure coverage for wear protection, sludge resistance, and fuel efficiency.
- Viscosity labels to consider: 0W-20, 5W-20, with 5W-30 as a possible alternative if your manual allows it and climate or driving style warrants it.
Bottom line: pick a product that is full-synthetic and clearly labeled with the appropriate ILSAC/API specification and the viscosity recommended by your manual.
Oil-change intervals and practical considerations
Oil-change timing varies with driving habits, climate, and oil type. The TSX benefits from consistent, manufacturer-recommended intervals, particularly when using synthetic oil, but the exact mileage or time frame is year-specific.
- With synthetic oil, many owners follow intervals around 7,500 to 10,000 miles (12,000 to 16,000 km) under normal driving, but always prioritize the schedule in your owner's manual.
- Severe service (short trips, extreme temperatures, towing, or heavy city driving) typically requires more frequent changes, often in the 3,000 to 5,000 mile range.
- Always monitor oil level and appearance between changes and perform a check if you notice consumption or leaks.
These guidelines provide a practical baseline, but the manufacturer’s recommended interval for your exact model year should be your primary reference point.
How to choose the right oil for your climate and driving style
Climate and how you drive have a meaningful impact on the oil you choose and how often you change it. For example, very cold environments favor oils with better cold-flow characteristics like 0W-20, while consistently hot temperatures might tolerate 5W-30 where permitted by the manual. Aggressive driving or frequent short trips can also shorten the interval between changes even with synthetic oil.
- Review the owner's manual for the exact viscosity and certification required for your TSX year and engine code.
- Prefer full-synthetic oil that meets ILSAC GF-5/GF-6 and API SN or newer, with a viscosity your manual endorses.
- Adopt the oil-change schedule that matches your driving conditions and climate, then adjust if you notice oil consumption or engine noise.
Following the manual and using a quality synthetic oil tuned to your environment will help maximize engine protection and performance over the life of your TSX.
Summary
For most Acura TSX models, a full-synthetic oil with a viscosity of 5W-20 is the safe default, with 0W-20 or 5W-30 as viable alternatives where the manual allows. Always verify the exact specification for your year and engine, use oils that meet ILSAC GF-5/GF-6 and API standards, and follow the manufacturer’s recommended service intervals, adjusted for climate and driving conditions. Regular checks and choosing the right synthetic oil will help preserve performance and longevity of the TSX’s engine.
What kind of oil does a 3.7 L V6 take?
A 3.7L V6 engine typically uses SAE 5W-20 motor oil, but it's crucial to check your owner's manual, as the exact type can vary by make and model. For example, some Ford 3.7L V6 engines specify 5W-20, while other models, like certain Jeeps, may call for 5W-30 or 10W-30 depending on the temperature.
Key takeaways
- 5W-20: This is the most common recommendation for 3.7L V6 engines, especially from Ford.
- Check your manual: Always consult your vehicle's owner's manual for the precise oil grade, as different manufacturers may have different specifications.
- Other viscosities: Some 3.7L V6 engines, like the Jeep Liberty, may require 5W-30 or 10W-30 depending on the ambient temperature.
- Additives: Do not use extra engine oil additives, as they are unnecessary and could potentially cause damage.
- Oil capacity: The amount of oil needed will also vary, but many 3.7L engines require around 6 quarts with a filter change.

Can I use 5w30 instead of 5W20 in my Acura?
You should not use 5W-30 instead of 5W-20 unless your owner's manual specifically permits it, as using a thicker oil can reduce fuel economy and may not properly lubricate high-tolerance engines, especially at startup. Always consult your owner's manual for the correct viscosity grade recommended by Acura for your specific model and engine. Some older models or performance engines might be an exception and require 5W-30, but most newer models are designed for the thinner 0W-20 or 5W-20 oil for fuel efficiency.
Risks of using 5W-30 instead of 5W-20
- Reduced fuel economy: Thicker oil creates more friction, causing the engine to work harder and consume more fuel.
- Engine lubrication issues: Newer engines are built with very tight tolerances. Thicker oil may not flow to critical areas as quickly, potentially causing wear, especially in cold weather.
- Potential for engine rattle: Thicker oil can sometimes cause a VTC (variable valve timing) rattle on cold starts.
When it might be acceptable
- If your owner's manual allows it: Some older Acura models, or specific performance versions like some RDX or RSX models, may have recommended 5W-30 oil.
- For temporary use in hot weather: In some cases, using 5W-30 temporarily in very hot climates might be acceptable, but you should always check the manual first.
- If you have a high-mileage engine: In older engines with high mileage, some people find that a slightly thicker oil provides a better seal. However, this is not a universal rule and can still lead to issues if the engine was not designed for it.
What to do
- Consult your owner's manual: This is the most crucial step. It will tell you the exact oil viscosity recommended for your vehicle, as well as any alternatives permitted under different conditions.
- If you have a newer model: Your car was likely designed for the thinner 0W-20 or 5W-20 oil for fuel efficiency. Stick with what the manufacturer recommends.
- If you accidentally used 5W-30: If you've already put in 5W-30, it likely won't cause immediate catastrophic damage, especially if it was a temporary top-off. However, it is best to get the correct oil as soon as possible to avoid potential long-term issues.
