Fluid Type Specifications
DIESEL ENGINE OIL QUALITY
This doughnut-shaped logo symbol is used on most oil containers to help you select the correct oil. It means that the oil has been certified by the American Petroleum Institute. You should look for this on the oil container, and use only those oils that display the logo. Oils designated as API CH-4 or CG-4 are best. The CH-4 or CG-4 designations may appear either alone, together or in combination with other API designations, such as API CH-4/SJ, CG-4/SH or CH-4/CG-4/SJ. These letters show American Petroleum Institute (API) levels of quality.
IMPORTANT: Oils that do not have one of these designations (CH-4 or CG-4) can cause engine damage which is not covered by the warranty.
DIESEL ENGINE OIL VISCOSITY
The recommended oil viscosity is SAE 15W-40.
NOTICE: Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Then, select the recommended oil viscosity.
IMPORTANT: However, you can use SAE 10W-30 if it is going to be colder than 0°C (32°F) before your next oil change. When it is very cold, below -18°C (0°F), you should use SAE 10W-30 to improve cold starting. SAE 30 may be used at temperatures above freezing, 0°C (32°F).
These numbers on the oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 10W-40 or SAE 20W-50.
