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. Synthetic oils often provide superior performance across a wider temperature range compared to conventional mineral oils.

Diesel engines and heavy-duty trucks frequently operate on 15W-40 or 20W-50 grades due to the extreme pressures they endure. High-performance engines, turbocharged units, or vehicles operating in hot climates often require 5W-40 or 10W-40.
When an engine is started, especially in cold weather, the oil is thick and sluggish, similar to cold honey. Older vehicles or those with high mileage may benefit from a slightly higher viscosity to compensate for worn engine clearances.

Understanding the engine oil viscosity chart is the single most important step in selecting the right lubricant for your vehicle. Matching Viscosity to Your Vehicle While the science is fascinating, the most critical application of the engine oil viscosity chart is selecting the grade recommended by your vehicle manufacturer.
