Understanding What 15W 40 Means
Before choosing any oil, I made sure to understand the viscosity rating. The “15W 40” indicates the oil’s thickness and flow characteristics. The “15W” means it performs well in winter or cold temperatures, allowing for easier starts. The “40” means it maintains good viscosity at high engine temperatures, offering solid protection during heavy-duty use. Knowing this helped me decide if it matched my vehicle’s requirements.
