Fuel Requirements(2.0-liter engine)
Vehicles equipped with catalytic
converters must use ONLY
UNLEADED FUEL, which will
reduce exhaust emissions and keep
spark plug fouling to a minimum.
Your Mazda will perform best with
regular unleaded fuel having an octane
rating (antiknock index) of at least 87
[(R+M)/2 method].
Fuel with a lower rating could cause
the emission control system to lose
effectiveness. It could also cause
engine knocking and serious engine
damage. (2.5-liter engine)

UNLEADED FUEL, which will
reduce exhaust emissions and keep
spark plug fouling to a minimum.
Your Mazda will perform best with
premium unleaded fuel having an
octane rating (antiknock index) of at
least 91 [(R+M)/2 method].
You may use a regular unleaded
gasoline with a rating from 87 to 90;
this will slightly reduce performance.
Also, fuel with a rating lower than 87
octane could cause the emission
control system to lose effectiveness. It
could also cause engine knocking and
serious engine damage.
U.S. federal law requires that octane
ratings be posted on gasoline station
pumps.
