2018 INFINITI Q50 fuel

9-6Maintenance and schedules
Fuel lines*:
Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tight-
en connections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.
CHASSIS AND BODY MAINTE-
NANCE
Brake lines and cables:
Visually inspect for proper installation.
Check for chafing, cracks, deterioration,
and signs of leaking. Replace any deterio-
rated or damaged parts immediately.
Brake pads, rotors, drums and linings:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/AWD/RWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage
of oil or grease. Under severe driving condi-
tions, inspect more frequently.
Tire rotation:
Tires should be rotated every 5,000 miles
(8,000 km) according to the instructions
under “Explanation of general maintenance
items” (P.9-2). When rotating tires, check for
damage and uneven wear. Replace if neces-
sary.
Transmission fluid/oil, differential oil and
transfer case oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles
(192,000 km)/144 months. For most peo-
ple, the odometer reading will indicate when
service is needed. However, if you drive very
little, your vehicle should be serviced at the
regular time intervals shown in the schedule.
After 120,000 miles (192,000 km)/144
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions;
should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.

CAPACITIES AND RECOMMENDED
FLUIDS/LUBRICANTS

10-4Technical and consumer information
FUEL INFORMATION (for
VR30DDTT engine model)
Use unleaded premium gasoline with an
octane rating of at least 91 AKI (Anti-Knock
Index) number (Research octane number 96).
INFINITI recommends the use of unleaded
premium gasoline with 93 AKI number
(Research octane number 98) to obtain the
maximum vehicle performance and the best
driveability.
If unleaded premium gasoline is not avail-
able, unleaded regular gasoline with an
octane rating of at least 87 AKI number
(Research octane number 91) may be tem-
porarily used, but only under the following
precautions:
.Have the fuel tank filled only partially
with unleaded regular gasoline, and fill
up with unleaded premium gasoline as
soon as possible.
. Avoid full throttle driving and abrupt
acceleration.
Use unleaded premium gasoline for max-
imum vehicle performance.
CAUTION
. Using a fuel other than that specified
could adversely affect the emission control system, and may also affect
warranty coverage.
. Under no circumstances should a
leaded gasoline be used, because this
will damage the three-way catalyst.
. Do not use a fuel containing more
than 15% ethanol in your vehicle.
Your vehicle is not designed to run on
a fuel containing more than 15%
ethanol. Using a fuel containing more
than 15% ethanol in a vehicle not
specifically designed for a fuel con-
taining more than 15% ethanol can
adversely affect the emission control
devices and systems of the vehicle.
Damage caused by such fuel is not
covered by the INFINITI new vehicle
limited warranty.
. Do not use fuel that contains the
octane booster methylcyclopentadie-
nyl manganese tricarbonyl (MMT).
Using fuel containing MMT may
adversely affect vehicle performance
and vehicle emissions. Not all fuel
dispensers are labeled to indicate
MMT content, so you may have to
consult your gasoline retailer for
more details. Note that Federal and
California laws prohibit the use of
MMT in reformulated gasoline. .
U.S. government regulations require
ethanol dispensing pumps to be iden-
tified by a small, square, orange and
black label with the common abbre-
viation or the appropriate percen-
tage for that region.
Gasoline specifications
INFINITI recommends using gasoline that
meets the World-Wide Fuel Charter
(WWFC) specifications where it is available.
Many of the automobile manufacturers
developed this specification to improve
emission system and vehicle performance.
Ask your service station manager if the
gasoline meets the World-Wide Fuel Char-
ter (WWFC) specifications.
Reformulated gasoline
Some fuel suppliers are now producing
reformulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. INFINITI supports efforts towards
cleaner air and suggests that you use
reformulated gasoline when available.
Gasoline containing oxygenates
Some fuel suppliers sell gasoline containing
oxygenates such as ethanol, MTBE and
methanol with or without advertising their
presence. INFINITI does not recommend the
