Fuel Requirements
Use unleaded gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (research octane number 91) for the KA24DE and VG33E
engines.
CAUTION: Use unleaded fuel only. Under no circumstances should leaded gasoline be used. It will damage the three way catalyst and increase
