CAUTION Replacing fuel system components with non-ethanol compatible components can damage your vehicle and may also affect the warranty coverage. Maintenance If you operate your vehicle using E-85 fuel, follow the correct maintenance log shown in the "NISSAN Service and Maintenance Guide". CAUTION Do not use ethanol mixture greater than 85% in your vehicle. It will cause difficulty in cold starting and may affect drivability. LTI2061 ENGINE OIL AND OIL FILTER RECOMMENDATIONS Selecting the correct oil It is essential to choose the correct grade, quality and viscosity engine oil to ensure satisfactory engine life and performance. Refer to "Recommended fluids/lubricants and capacities" in this section. NISSAN recommends the use of an energy conserving oil in order to improve fuel economy. Select only engine oils that meet the American Petroleum Institute (API) certification or International Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils have the API certification mark on the front of the container. Oils which do not have the specified quality label should not be used as they could cause engine damage. 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. Technical and consumer information 9-7
