Choosing the incorrect grade can lead to poor fuel economy, inadequate lubrication, and ultimately, costly mechanical failures. " Consequences of Ignoring the Chart.
Engine Oil Viscosity Chart Maintenance Interval Guide
The number after the dash indicates the oil's thickness at the normal operating temperature of 100°C (212°F); a higher number like 40 or 50 signifies a thicker oil that maintains a strong film to protect engine components under heat and pressure. Understanding the engine oil viscosity chart is the single most important step in selecting the right lubricant for your vehicle.
This dynamic balance ensures consistent protection whether you are starting your car on a winter morning or driving on a scorching summer highway. Diesel engines and heavy-duty trucks frequently operate on 15W-40 or 20W-50 grades due to the extreme pressures they endure.
How to Use the Engine Oil Viscosity Chart for Optimal Maintenance Intervals
Decoding the Numbers: What the Viscosity Grade Means The numbers on a container of motor oil, such as 5W-30 or 10W-40, are not arbitrary; they are a standardized measurement of its viscosity performance. A multi-grade oil is engineered with additives that allow it to flow freely when cold (the first number) while resisting thinning and breaking down when the engine reaches its operating temperature (the second number).
