Use clean, fresh unleaded gasoline with a minimum Antiknock Index of 90.
The Antiknock Index is posted on service
station pumps. The octane rating
of a gasoline is a measure of its resistance
to detonation or “knocking.” The
Antiknock Index is an average of the
Research Octane Number (RON) and
the Motor Octane Number (MON) as
shown in the table.
NOTICE
Use minimum of 90 octane gasoline only to prevent severe engine damage.
NOTICE
If engine “knocking” or “pinging” occurs, use a different brand of gasoline of a higher octane rating. If this condition is allowed to continue it can lead to severe engine damage.
Gasoline quality is important.
Fuels of low quality or not meeting standard industry specifications may result in unsatisfactory performance. Operating problems that result from the use of poor quality or nonrecommended fuel may not be covered under your warranty.
