2020 MAZDA MODEL CX-5 fuel additives

Fuel and Engine Exhaust Precautions
▼Fuel Requirements (SKYACTIV-G 2.0,
S K YA C T I V- G 2 . 5 , S K YA C T I V- G 2 . 5 T )
Vehicles with catalytic converters or oxygen sensors must use ONLY 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 above)
*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 negatively affect the emission control
system performance and could also cause en gine knocking and serious 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 using 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 compounds 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 containing alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resu lting from the use of the following may not be
covered by the warranty.
Gasohol containing more 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 specification Ultra-Low Sulfur Diesel
(ULSD, 15 ppm sulfur or less) fuel that meets the ASTM D975 standard or the equivalent.

Fuel grade labels are visible on fuel-filler lid, therefore, verify the fuel grade before
refueling. If the fuel grade cannot be verified, ask the gas station 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 th e equivalent for your vehicle. Use of gasoline
or kerosene in diesel engines will result 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 pumped 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.
 Do not mistake the refueling port for the DEF
filler port. If fuel was added to the DEF
filler
port by mistake, 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 fuel in the DEF filler port could cause
damage to the emission control system.
Diesel fuel only
DEF only
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) may freeze and clog the fuel
pipe, leading to problems 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.
▼Emission Control System (SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-G
2.5T)
This vehicle is equipped with an emission con
trol system (the catalytic converter is part of
this system) that enables the vehicle to comply with existing exhaust emissions
requirements.
WA R N I N G
Never park over or near anything flammable:
Parking over or near anything flammable, such as dry grass, is dangerous. Even with the
engine turned off, the exhaust system remains very hot after normal use and could ignite
anything flammable. A resulting
fire could cause serious injury or death.
CAUTION
Ignoring the following precautions could cause le
ad to accumulate on the catalyst inside the
converter or cause the converter to get very ho t. Either condition will damage the converter
and cause poor performance.
 USE ONLY UNLEADED FUEL.
 Do not drive your Mazda with any sign of engine malfunction.
 Do not coast with the ignition switched
off.
 Do not descend steep grades in gear with the ignition switched off.
 Do not operate the engine at hi gh idle for more than 2 minutes.
 Do not tamper with the emission control syst em. All inspections and adjustments must be
made by a qualified technician.
 Do not push-start or pull-start this vehicle.
NOTE
Under U.S. federal law, any modification to the original-equipment emission control
system before the first sale and registration of a vehicle is subject to penalties. In some
states, such modification made on a used vehicle is also subject to penalties.
While the engine is off, the sound of a valve opening and closing can be heard at the rear
of the vehicle, however this does not indicate an abnormality. The vehicle has a
self-checking device and it oper ates while the engine is off.
