Engine Oil Selection.

Proper engine oil selection is very important for optimum engine performance, efficiency and durability.

A new service API classification category has been adopted. The designation for this category is "SH". The "SH" category is intended to replace the "SG" category and provide improved performance in: deposit control, oil oxidation, wear, rust, and corrosion protection. "SH" category oils may be used in applications where "SG" and earlier categories are recommended.

Oil Temperature Chart:

The appropriate SAE viscosity grade depends on existing climatic conditions. Refer to the temperature chart illustrated when selecting viscosity grades for expected temperature ranges. Brief variations in temperature are no cause for alarm.

Lubricants that do not list both an SAE grade number and an API service classification on the container should not be used.
