NISSAN recommends the use of premium unleaded gasoline with an octane rating of at least 91 AKI number (Research octane number 96). If premium unleaded gasoline is not available you may use regular unleaded gasoline with an octane rating of at least 87 AKI number (Research octane number 91), but you may notice a decrease in performance. For additional information, see "Capacities and recommended fuel/lubricants" in the "Technical and consumer information" section. RECOMMENDED ENGINE OIL: ● API Certification Mark ● API grade SG, Energy Conserving II or API grade SH, SJ or SL ● ILSAC grade GF-II or GF-III ● 5W-30 Viscosity preferred See "Engine oil and oil filter recommendation" in the "Technical and consumer information" section of this manual. CAUTION ● Using a fuel other than that specified could adversely affect the emission control system, and may also affect the warranty coverage. ● Under no circumstances should a leaded gasoline be used, because this will damage the three-way catalyst. ● Do not use E-85 fuel in your vehicle.
