Wheel Hub Bearing Lubricant

NLGI #2 or #3

Diesel Exhaust Fluid (DEF)

American Petroleum Institute (API) certified diesel exhaust fluid (DEF) Internation Organization for Standardization (ISO): AUS 32 ISO 2241

When to Add Engine Oil

If the oil is below the lower hole at the tip of the dipstick, you need to add at least one quart/liter of oil. But you must use the right kind.

Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the "Full" level that shows the proper operating range, the engine could be damaged.
Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you are through.

What Kind of Engine Oil to Use

Oils designated as API CJ-4 recommended for the vehicle. The CJ-4 designations can appear either alone, together, or in combination with other American Petroleum Institute (API) designations, such as API CJ-4. These letters show API levels of quality.
