recommended. Some fuel stations offer
fuels posted as regular with an octane
rating below 87, particularly in high altitude
areas. Fuels with octane levels below 87
are not recommended.

Regular unleaded gasoline with a pump
(R+M)/2 octane rating of 87 is
recommended. Some fuel stations offer
fuels posted as regular with an octane
rating below 87, particularly in high altitude
areas. Fuels with octane levels below 87

provide improved performance and is
recommended for severe duty usage such

knocks heavily while you are using fuel with
the recommended octane rating, see an
authorized dealer to prevent any engine
