With the abundance of engine oil options available today — from conventional to semi-synthetic and fully synthetic blends — it’s no surprise that many vehicle owners feel overwhelmed when it comes to choosing the right one. But making the correct decision is more than just a matter of price or preference. The right engine oil ensures smooth performance, reduces friction, enhances fuel efficiency, and helps prevent costly repairs down the road.

Adding another layer of confidence to the decision-making process is the introduction of SIRIM-certified engine oils. This certification gives consumers peace of mind, ensuring the product has undergone rigorous testing and meets high performance and safety standards. Here’s what you need to know to confidently select the ideal oil for your vehicle.

Conventional oil, derived from crude petroleum, is typically the most budget-friendly option. It’s commonly used in older car models or under normal driving conditions. While it offers basic protection and lubrication, it tends to degrade faster in extreme temperatures, requiring more frequent oil changes.

Semi-synthetic oil strikes a balance between affordability and performance. As a blend of conventional and synthetic oils, it offers better thermal resistance, longer oil life, and enhanced engine protection — making it ideal for daily drivers who want efficiency without breaking the bank.

Fully synthetic oil is engineered for high performance and extreme conditions. It provides exceptional lubrication, thermal stability, and oxidation resistance. Though more expensive, its ability to reduce engine wear, improve fuel economy, and extend maintenance intervals makes it a smart investment — especially for modern vehicles and performance cars.

  • Viscosity Grades Matter
    Oil viscosity (e.g., 5W-30, 10W-40) determines how it flows at different temperatures. Always follow the viscosity grade recommended by your vehicle’s manufacturer for optimal lubrication and protection.
  • Driving Conditions Count
    If you regularly drive in extreme heat, freezing climates, or stop-and-go traffic, synthetic oil offers better protection against wear and temperature fluctuations.
  • Manufacturer’s Recommendations
    Never ignore your vehicle’s owner’s manual. Using the wrong oil can reduce performance, increase wear, and even cause engine damage over time.

While synthetic oils may cost more upfront, they can lead to savings in the long run. Their enhanced durability means fewer oil changes, improved fuel efficiency, and reduced wear and tear — all contributing to lower maintenance costs over time. Vehicles running on synthetic oil tend to last longer and operate more efficiently, making it a wise financial decision in the big picture.

Quality and authenticity are non-negotiable when it comes to engine oil. The SIRIM Genuine Products: Engine Oil for Motor Vehicle Certification Scheme helps consumers confidently identify products that meet strict quality and safety benchmarks.

According to Ts. Hasnol Zakaria, Head of Product Certification and Inspection at SIRIM QAS International, “This certification is essential in ensuring consumers have access to genuine, safe, and performance-tested engine oils. It provides peace of mind by guaranteeing the oil meets strict industry standards for engine protection, fuel efficiency, and long-term durability.”

In a market plagued by counterfeit and substandard oils, this certification acts as a trusted seal of approval — protecting both engines and wallets.

  • Daily Commuters benefit from semi-synthetic or full synthetic oils, which improve fuel efficiency and reduce maintenance frequency.
  • Performance and Luxury Cars demand fully synthetic oil to maximize engine output and longevity.
  • Heavy-Duty and Commercial Vehicles require high-viscosity synthetic oils to withstand extended hours and heavier loads.
  • Older Cars may run best on conventional or high-mileage synthetic blends, which help condition seals and reduce oil consumption.

Choosing the right engine oil is essential for protecting your vehicle and maximizing its performance. While conventional and synthetic oils each have their place, opting for SIRIM-certified engine oil gives you added assurance in terms of quality and reliability. Whether you’re navigating city traffic or powering down highways, using the correct oil will keep your engine running smoothly for years to come.

For guaranteed quality and peace of mind, always look for engine oils verified by SIRIM QAS International Sdn Bhd — a trusted name working to ensure the safety and performance of the lubricants powering your drive.
