Nissan Sentra Service Manual: Fuel (Regular Unleaded Gasoline Recommended)
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91). 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.
Three Way Catalyst
If a large amount of unburned fuel flows into the catalyst, the catalyst
temperature will be excessively high. To
prevent this, follow the instructions.
Use unleaded gasoline only. Leaded gasol ...
