Oil viscosity comparison matrix

How every grade relates

This oil viscosity comparison matrix shows how every common SAE grade relates to the others: grades with the same first number share cold-start behavior, and grades with the same second number share hot-temperature thickness. Use it to see differences at a glance, then confirm the grade your owner’s manual specifies.

Compare two grades
