Precautions For Fuel

Unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (research octane number 96). If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87 AKI (research octane number 91) can be used.
However, for maximum vehicle performance the use of unleaded premium gasoline is recommended.

CAUTION: Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.
Under no circumstances should a leaded gasoline be used, since this will damage the three way catalyst.
