Multi-Grade Oils Historically, engines required single-grade oils that were formulated specifically for either summer or winter conditions. This thermal sensitivity is why the oil viscosity chart is split into two numbers, such as 5W-30, representing performance in both low and high temperatures.
Oil Viscosity Chart Maintenance Tips
Conventional Lubricants The base oil used in the formulation plays a significant role in how the oil behaves on the viscosity chart. Using oil that is too thick can result in poor fuel economy and sluggish engine performance, while oil that is too thin may fail to protect against metal-on-metal contact.
The vertical axis typically represents the thickness or flow resistance at high temperatures, while the horizontal axis indicates cold-start flow capabilities. Selecting the correct viscosity grade ensures optimal performance, protection against wear, and fuel efficiency.
Oil Viscosity Chart Maintenance Tips
Before a product reaches the shelf, it undergoes rigorous laboratory testing to simulate extreme pressure and temperature conditions. For instance, residents in colder regions should prioritize the "W" rating, while those in consistently hot climates may focus more on the high-temperature number to ensure the oil does not break down.
