Choosing the Right 5W40 Engine Oil for Your Car: A Motul India Guide


Keeping your car’s engine healthy and running smoothly is paramount to its longevity and performance. Motor oil plays a critical role in this, and choosing the right one can be confusing, especially when faced with an all-purpose solution such as 5W40 engine oil. Thankfully, you have Motul covering all your engine oil queries in the form of this guide, which will navigate you through the key factors to consider when selecting the perfect 5W40 oil for your car, ensuring optimal protection and peak performance.

The 5W40 car engine oil is a fantastic multigrade choice for Indian car owners

The “5W40” designation on an engine oil bottle refers to its viscosity grade, a crucial indicator of its flow properties at different temperatures. The “W” stands for winter, and the number preceding it (5 in this case) signifies the oil’s ability to flow easily at cold temperatures. This ensures smoother cold starts and quicker lubrication upon engine ignition, minimizing wear and tear. The higher number following the “W” (40 here) indicates the oil’s viscosity at operating temperatures. A 5W40 oil maintains a good level of viscosity even when the engine is hot, providing consistent lubrication and protection against friction.

Reasons to consider 5w40 car engine oil

5W40 oil offers a versatile blend, making it suitable for a wide range of driving conditions and climates. Here’s why it might be the perfect choice for your car:

  • All-season performance: The multi-grade nature of 5W40 allows for easy flow during cold starts and maintains viscosity at high temperatures, making it ideal for year-round use in moderate climates.
  • Reduced friction and wear: The lubricating properties of 5W40 oil minimize friction between engine components, protecting them from wear and tear, ultimately extending engine life.
  • Improved fuel economy: Certain 5W40 oils, particularly synthetic blends, can offer slightly better fuel efficiency compared to thicker oils due to their lower resistance to flow. Some brands, such as Motul also offer fully synthetic 5w40 engine oil solutions.

What to consider before choosing a specific brand of 5w40 engine oil

While 5W40 might be the right viscosity grade, there’s more to choosing the perfect oil for your car. Here are some crucial factors to consider:

  1. Manufacturer recommendations: Your car’s owner’s manual is the ultimate authority. It will specify the recommended oil grade and API service category for your specific engine. Deviate from this recommendation only under specific circumstances, like high-performance driving with a manufacturer-approved alternative.
  2. Your driving conditions:
    • Climate: While 5W40 works well in moderate climates, consider extremes. If you face very cold winters, a full synthetic 5W40 might be better for easier cold starts. Conversely, scorching summers might demand an oil specifically formulated for high-heat resistance.
    • Driving style: Do you primarily take short trips with frequent starts and stops, or do you embark on long highway journeys? Stop-and-go traffic or towing heavy loads puts extra stress on the engine, and you might require an oil with specific additives for enhanced protection under such conditions.
  3. Oil type:
    • Full Synthetic: These oils offer top-tier performance and protection due to their meticulously engineered molecular structure. They excel in extreme temperatures, resist breakdown, and offer extended oil change intervals. However, they come at a premium price.
    • Synthetic Blend: A popular choice, synthetic blends combine synthetic and conventional oil, providing a good balance between performance, price, and protection. They offer better performance compared to conventional oil and are generally more affordable than full synthetics.
    • Conventional Oil (Mineral): The most economical option, conventional oil is suitable for low-mileage vehicles or those not driven under extreme conditions. However, it may not offer the same level of protection or longevity as synthetic options.
  4. API Certification:Look for the API donut symbol on the oil bottle. This signifies that the oil meets specific performance standards set by the American Petroleum Institute for gasoline engines. The specific API service category will also be mentioned on the bottle (e.g., API SN). Ensure this category aligns with your manufacturer’s recommendation.
