Precautions for Fuel (Unleaded Premium Gasoline Recommended)

Precautions for Fuel (Unleaded Premium Gasoline Recommended)
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91).

For improved vehicle performance, NISSAN/INFINITI recommend the use of unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).

CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.
