Which engine oil is best for Honda Insight?
The best engine oil for the Honda Insight is a 0W-20 full synthetic that meets Honda’s HTO-06 specification and the latest API/ILSAC standards. Use Honda Genuine 0W-20 or another reputable brand that explicitly lists compatibility with HTO-06.
The Insight uses a modern 1.5-liter Atkinson-cycle hybrid engine, so choosing the right oil matters for efficiency, cold starts, and long-term reliability. The key considerations are viscosity, synthetic content, and whether the oil meets Honda’s spec and current API/ILSAC standards. This guide explains how to pick the right oil and what to look for on the bottle.
Key requirements for Honda Insight engine oil
Viscosity and standards
When selecting oil, you should focus on the viscosity grade, whether the oil is synthetic, and the standards it carries. Honda specifies 0W-20 viscosity and requires the oil to meet Honda’s HTO-06 along with current API and ILSAC standards.
- Viscosity: 0W-20
- Oil type: Full synthetic
- Standards: API SP or newer; ILSAC GF-6; Honda HTO-06
- Compatibility: Oils that carry HTO-06 along with API/ILSAC specs
In short, the best option is a 0W-20 full synthetic oil that explicitly meets these specifications.
Recommended oil brands and how to choose
Brand options and what to look for
To simplify your selection, look for 0W-20 full synthetic oils that clearly state compatibility with Honda HTO-06 and API SP/ILSAC GF-6. Common options you’ll find at auto parts stores and dealers include the following, though availability varies by region.
- Honda Genuine 0W-20 engine oil
- Mobil 1 0W-20 Full Synthetic
- Castrol EDGE 0W-20 Full Synthetic
- Pennzoil Platinum Full Synthetic 0W-20
- Valvoline Advanced Full Synthetic 0W-20
Always check the bottle label to confirm 0W-20, full synthetic, and API SP/ILSAC GF-6 readiness, as well as Honda HTO-06 compatibility. If in doubt, ask a dealer or consult the service manual for your exact model year and market.
Synthetic vs conventional: what works best for the Insight?
When to choose synthetic
For the Honda Insight, synthetic 0W-20 is generally recommended. Synthetic oil provides better low- and high-temperature protection, reduced evaporation, and improved fuel economy—benefits that align with the hybrid’s emphasis on efficiency and long-term reliability. Conventional 0W-20 is typically not recommended for newer Hondas.
Keep in mind that some markets still offer high-quality conventional 0W-20, but if you want maximum protection and the longest drain intervals, a full synthetic is the safer choice. Always follow the maintenance schedule in the owner’s manual to determine oil-change intervals based on your driving conditions.

- Choose a 0W-20 full synthetic oil that lists API SP or newer, ILSAC GF-6, and Honda HTO-06 compatibility on the label.
- Consider climate and driving style when deciding on drain intervals and whether to use a bottle that supports longer change intervals.
Following these steps helps ensure you select an oil that protects your hybrid’s performance and longevity while maximizing fuel efficiency.
Summary
The Honda Insight benefits most from a 0W-20 full synthetic engine oil that meets Honda's HTO-06 specification and the latest API/ILSAC standards.

What is Honda's preferred oil?
American Honda recommends using Honda Genuine Motor Oil, sold and available at Honda dealers . If Honda Genuine Motor Oil is not used, conventional motor oil of a premium-grade or an ultimate full synthetic blend may be used and must contain the specified viscosity grade indicated in your Owner's Manual.
What kind of oil does a Honda Insight Hybrid take?
The recommended oil for a Honda Insight is SAE 0W-20 full synthetic, although SAE 5W-20 or 5W-30 can be used if 0W-20 is not available. It's crucial to use a high-quality full synthetic oil that meets the specific viscosity and API specifications for your model year to ensure optimal engine performance and longevity.
Oil type by viscosity and grade
- Primary recommendation: SAE 0W-20 full synthetic motor oil.
- Alternative: SAE 5W-20 or 5W-30 may be used if 0W-20 is not available, particularly for older or high-mileage engines.
- API Specifications: Look for an oil that meets the requirements of your specific Honda Insight model, such as API SN or newer standards.
Important considerations
- Use full synthetic: Using a full synthetic oil is generally recommended for modern Honda Insights, as it provides superior protection and performance compared to conventional oil.
- Check your owner's manual: The best way to confirm the correct oil type is to consult your owner's manual, as requirements can vary slightly by model year.
- Avoid thicker oils: For most modern Insights, using thicker oils like 5W-30 or 5W-40 in cold conditions can lead to reduced lubrication during stops and starts, which can increase engine wear.

Is 5W-30 good for hybrid cars?
You'll be fine with 5W30 as long as it's not freezing temps and you let the oil heat up properly before putting high load on the engine. While it's not wrong, it's also not recommended. If they offer to change to 0W16 for free, go for it.
