NISSAN recommends mineral based oils. These oils must however, meet the API quality and SAE viscosity ratings specified for your vehicle. Oil additives NISSAN does not recommend the use of oil additives. The use of an oil additive is not necessary when the proper oil type is used and maintenance intervals are followed. Oil which may contain foreign matter or has been previously used should not be used. Oil viscosity STI0367A 1 k API certification mark 2 k API service symbol ENGINE OIL AND OIL FILTER RECOMMENDATION Only those engine oils with the American Petroleum Institute (API) certification mark on the front of the container should be used. This type of oil supersedes the existing API SG, SH, or SJ and Energy Conserving I & II categories. If you cannot find engine oil with the API certification mark, use an API grade SG/SH, Energy Conserving I & II or API grade SJ or SL, Energy conserving oil. An oil with a single designation SG or SH, or in combination with other categories (for example, SG/CC or SG/CD) may also be used if one with the API certification mark cannot be found. An ILSAC grade GF-I, GF-II & GF-III oil can also be used. Selecting the correct oil It is essential to choose the correct quality, and viscosity oil to ensure satisfactory engine life and performance. NISSAN recommends the use of a low friction oil (energy conserving oil) in order to improve fuel economy and conserve energy. Oils which do not have the specified quality label should not be used as they could cause engine damage. The engine oil viscosity or thickness changes with temperature. Because of this, it is important that the engine oil viscosity be selected based on the temperatures at which the vehicle will be operated before the next oil change. The "Recommended SAE viscosity number" chart (on the next page) shows the recommended oil viscosities for the expected ambient temperatures. Choosing an oil viscosity other than that recommended could cause serious engine damage. Selecting the correct oil filter Your new NISSAN vehicle is equipped with a high-quality genuine NISSAN oil filter. When replacing, use a genuine NISSAN oil filter or its equivalent for the reason described in "Change intervals". Technical and consumer information 9-5
