Fuel and Engine Exhaust Precautions
▼Fuel Requirements (SKYACTIV-G 2.5, SKYACTIV-G 2.5T)
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

To achieve maximum engine performance, use the specified fuel.
Fuel Octane Rating*1 (Anti-knock index)
Regular unleaded fuel 87 [(R+M)/2 method] or above (91 RON or ab ove)
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
Fuel with a rating lower than 87 octane (91 RON) will negativel y affect the emission control
system performance and could also cause engine knocking and ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop us ing gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
Gasoline blended with oxygenates such as alcohol or ether compo unds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline conta ining alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the following may not be
covered by the warranty.
Gasohol containing mo re than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

▼Fuel Requirements
(SKYACTIV-D 2.2)
The vehicle will operate efficiently on diesel fuel with specif ication Ultra-Low Sulfur Diesel
(ULSD, 15 ppm sulfur or less) f uel that meets the ASTM D975 standard or the equivalent.
Fuel grade labels are visible on fuel-filler lid, therefore, ve rify the fuel grade before
refueling. If the fuel grade cannot be verified, ask the gas st ation attendant.
CAUTION
Never use fuel other than specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or less)
fuel that meets the ASTM D975 standard or the equivalent for your vehicle. Use of gasoline
or kerosene in diesel engines will resu lt in fuel system and engine damage.
 Never use diesel fuel with concentrations of methyl ester bio-diesel higher than 5 % (B5),
such as B20 or B100.
 Never add fuel system additives other than a Mazda genuine product, otherwise the
emission control system could be damaged. Consult an Authorized Mazda Dealer for
details.
 If any type of incorrect fuel is accidently pu mped into the fuel tank, do not turn on the
engine and drive the vehicle. Consult an Authorized Mazda Dealer for assistance.
Turning on the engine or driving the vehicle with the incorrect fuel could cause damage to
the fuel pump and fuel injectors.
NOTE
Fuel for winter driving is available. Ask the gas station attendant for details.
When refueling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.
Low outside temperatures
When the outside temperature is low, diesel fuel (light oil) ma y freeze and clog the fuel
pipe, leading to probl ems such as the engine not starting. When driving to a cold region, add
winter grade diesel fuel as soon as possible.
WA R N I N G
Never use engine starting assist additives:
Using engine starting assist additives is dangerous because they may cause a vehicle
explosion or a vehicle runaway condition, leading to serious injury or death.
