Which Engine Oil Grade Is Right for Your Vehicle?
When it comes to protecting your engine and ensuring long-term performance, selecting the correct engine oil grade is one of the most important decisions you can make. With so many oils on the market—each with different viscosities, blends, and approvals—navigating the options can feel overwhelming. In this guide, we break down oil grades, explain how they work, and help you make an informed choice based on your vehicle, driving habits, and local climate.
Understanding Engine Oil Grade
Engine oil grade refers to the oil’s viscosity—how thick or thin it is—and its ability to perform under varying temperatures. These grades are set by the Society of Automotive Engineers (SAE) and are displayed in combinations like 5W-30 or 10W-40.
-
First number (e.g. 5W): Cold temperature performance. The lower the number, the better the flow in cold conditions.
-
Second number (e.g. 30): Performance at engine operating temperature. A higher number means better protection at high temperatures.
Modern engines often require lower viscosity oils like 0W-20 or 0W-10 to improve fuel economy and reduce emissions.
Types of Engine Oil
Understanding the types of oil helps you choose what suits your vehicle best:
Mineral Oil:
Basic and affordable, ideal for older engines. Requires more frequent changes and offers limited performance in extreme temperatures.
Semi-Synthetic Oil:
Blends mineral and synthetic oils for better protection at a lower cost than full synthetics. A good mid-range option.
Synthetic Oil:
Engineered for superior lubrication and performance across all temperatures. Recommended for most modern engines due to its longevity and protection against wear.
Choosing the Right Engine Oil Grade
1. Follow Your Manufacturer’s Recommendations
Always refer to your owner’s manual. Manufacturers specify viscosity and oil type based on engine design and performance requirements. Using the wrong oil can lead to decreased efficiency or void your warranty.
2. Check for Manufacturer Approvals
Beyond SAE ratings, many brands require specific certifications like API or ACEA. Some also have proprietary standards. Examples include:
-
2020 VW Amarok 2.0 TDI CR 420: Requires 5W-30 with VW 507.00 spec → Mobil 1 ESP 5W-30.
-
2020 Toyota Hilux 2.8 TDI: Requires 0W-30 or 5W-30 with ACEA C2 → Mobil 1 ESP 5W-30.
-
2020 Mazda 3 Skyactiv-G 2.0: Recommends 0W-20 to 10W-30 with ACEA SL → Mobil 1 5W-30.
-
2012 D22 Nissan Navara 2.5 dCi: Recommends 5W-30 with API CF/B1-B5 → Mobil Delvac Modern 15W-40.
3. Consider Your Climate
-
Cold climates: Use lower viscosity oils (e.g. 0W-20) for better flow at startup.
-
Hot climates: Use higher viscosity oils (e.g. 10W-30) to prevent thinning at high temperatures.
Final thoughts
Choosing the right engine oil grade is critical for maintaining your vehicle’s performance, efficiency, and longevity. Always consult your manufacturer’s recommendations, consider your local climate, and use approved products to avoid unnecessary wear or damage.
