Yes, 5W-30 oil is generally a good choice for 660cc cars in Pakistan, but it depends on the following factors:
- Engine Type and Manufacturer's Recommendation
Always check the ownerâs manual of your car to confirm the recommended oil grade. Many small, modern engines, such as those in 660cc vehicles, are designed to run efficiently with thinner oils like 5W-30 for better fuel economy and performance.
Most Japanese kei cars (660cc), which are common in Pakistan, recommend 5W-30 or similar grades.
- Weather and Climate
Pakistan experiences a range of temperatures depending on the region and season:
Hot Weather (e.g., Karachi, Lahore, Multan): 5W-30 performs well, but in extremely high temperatures, you could consider 5W-40 for better high-temperature stability.
Cold Weather (e.g., Northern Areas): 5W-30 is excellent due to its ability to flow easily during cold starts.
- Engine Health and Mileage
Newer or Well-Maintained Engines: Use 5W-30 for optimal performance and efficiency.
Older Engines or Higher Mileage (100,000 km+): If the engine consumes oil or has wear, you might need a slightly thicker grade like 10W-40, but only after consulting a mechanic.
- Oil Quality
Ensure the oil is fully synthetic or semi-synthetic, as these are better for smaller, high-performance engines found in 660cc cars.
Use high-quality brands like Shell, Total, ZIC, Mobil 1, or Liqui Moly, and verify their authenticity to avoid counterfeit products.
Final Advice
If your car manufacturer specifies 5W-30 and your engine is in good condition, itâs an excellent choice for Pakistani driving conditions. However, always match the oil grade to your carâs specific requirements for the best performance and longevity.

why Pak suzuki recommends 10w-40 in new alto 660cc car? whereas for these cars mostly 5w-30 is recommended

ChatGPT
Pak Suzuki recommends 10W-40 for the new Alto 660cc in Pakistan primarily due to local operating conditions, which include the following factors:
- Hot Weather Conditions
Pakistan's climate, especially in urban centers like Karachi, Lahore, and Multan, can get extremely hot in summers, with temperatures exceeding 40°C in some regions.
A 10W-40 oil offers better high-temperature protection compared to 5W-30, making it more suitable for sustained operations in such conditions.
- Local Driving Patterns
Stop-and-go traffic, shorter trips, and heavy loads on small engines (common in congested urban environments) can cause the engine to run hotter.
A thicker oil like 10W-40 can maintain viscosity and protect engine components under such stress.
- Cost and Oil Consumption Considerations
10W-40 oils are often cheaper than fully synthetic 5W-30 oils, and Suzuki may factor affordability for its target market in Pakistan.
Slightly thicker oils like 10W-40 also reduce the chances of oil consumption or leaks, which could occur more frequently in small, high-compression engines in warmer climates.
- Marketing and Dealer Influence
Pak Suzuki might also recommend 10W-40 for simplicity across its product line and to match the available service offerings at authorized dealerships.
What Should You Use?
Manufacturerâs Warranty: If your car is under warranty, follow Suzukiâs recommendation of 10W-40 to ensure compliance with service terms.
Alternative: If you prioritize better fuel efficiency and smoother engine performance, and drive in milder climates or maintain proper servicing, you can consider using 5W-30 (fully synthetic). Always verify this change with your service provider to ensure no warranty impact.
Why Do Japanese OEMs Recommend 5W-30?
In Japan, where these engines are originally designed, the climate is generally milder, and the fuel quality is superior. These factors allow for the use of thinner oils like 5W-30.
Pak Suzukiâs recommendation of 10W-40 reflects an adaptation to local conditions, but 5W-30 would still be a good choice if climate and usage align with global standards.
