Choosing the right fuel
²Use only UNLEADED FUEL. The use of leaded fuel is
prohibited by law and could damage your vehicle.
² Do not use fuel containing methanol. It can damage critical fuel
system components.
² Your vehicle was not designed to use fuel or fuel additives with
metallic compounds, including manganese-based compounds
containing MMT.
² Repairs to correct the effects of using a fuel for which your
vehicle was not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªRegularº unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as ªRegularº that
are sold with octane ratings of 86 or lower in high altitude areas.
NOTE:Do not be concerned if your engine sometimes knocks lightly.
However, if it knocks heavily under most driving conditions while you are
using fuel with the recommended octane rating, see your authorized
Mazda dealer to prevent any engine damage.
Fuel quality
NOTE:If you are experiencing starting, rough idle or hesitation
driveability problems during a cold start, try a different brand of
ªRegularº unleaded gasoline. ªPremiumº unleaded gasoline is not
recommended (particularly in the United States) because it may cause
these problems to become more pronounced. If the problems persist, see
your authorized Mazda dealer.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating.
Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in
your fuel may not be covered by your warranty.
