2023 SUBARU BRZ Gas cap

Fuel
224need to add any fuel system cleaning
agents to your fuel tank.
Many gasolines are now blended with
materials called oxygenates. Use of these
fuels can also help keep the air cleaner.
Oxygenated blend fuels, such as ethanol
(ethyl or grain alcohol) may be used in
your vehicle, but should contain no more
than 15% ethanol for the proper operation
of your SUBARU.
Do not use any gasoline that contains
more than 15% ethanol, including from
any pump labeled E30, E50 or E85 (which
are only some examples of fuel containing
more than 15% ethanol).
In addition, some gasoline suppliers are
now producing reformulated gasolines,
which are designed to reduce vehicle
emissions. SUBARU approves the use of
reformulated gasoline.
If you are not sure what the fuel contains,
you should ask your service station oper-
ators if their gasolines contain detergents
and oxygenates and if they have been
reformulated to reduce vehicle emissions.
As additional guidance, only use fuels
suited for your vehicle as explained in the
following description.
 Fuel should be unleaded and have an
octane rating no lower than that specified
in this manual. 
Methanol (methyl or wood alcohol) is
sometimes mixed with unleaded gasoline.
Methanol can be used in your vehicle
ONLY if it does not exceed 5% of the fuel
mixture AND if it is accompanied by suffi-
cient quantities of the proper cosolvent
and corrosion inhibitors required to
prevent damage to the fuel system. Do not
use fuel containing methanol EXCEPT
under these conditions.
 If undesirable driveability problems are
experienced and you suspect they may be
fuel related, try a different brand of gaso-
line before seeking service at your
SUBARU dealer.
 Fuel system damage or driveability
problems which result from the use of
improper fuel are not covered under the
SUBARU Limited Warranty.
■ Fuel Filler Lid and Cap▼ Locations of the fuel filler lid▼RefuelingOnly one person should be involved in
refueling. Do not allow others to approach
the area of the vehicl e near the fuel filler
pipe while refueling is in progress.
Be sure to observe any other precautions
that are posted at the service station.
1. Stop the vehicle, turn the ignition
switch to the “OFF” position and turn off all
the other electrical components.
2. Push the rear side of the fuel filler lid.
If the fuel filler lid is locked, perform one of
the operations below.
Press the “ ” button on the key fob.

Press the unlock side of the power
door locking switch.
3. The fuel filler lid opens automatically.
Open it further by hand.
1) Open
2) Close4. Remove the fuel filler cap by turning it
slowly counterclockwise.
5. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
WARNING
Before opening the fuel filler cap,
first touch the veh icle body or a
metal portion of the fuel pump or
similar object to discharge any
static electricity that may be present
on your body. If your body is carry-
ing an electrostatic charge, there is
a possibility that an electric spark
could ignite the fuel, which could
burn you. To avoid acquiring a new
static electric charge, do not get
back into the vehicle while refueling
is in progress.
WARNING
 Gasoline vapor is highly flam-
mable. Before refueling, always
turn the ignition switch to the
“OFF” position first and then
close all vehicle doors and
windows. Make sure that there
are no lighted cigarettes, open
flames or electrical sparks in the
adjacent area. Only handle fuel
outdoors. Quickly wipe up any
spilled fuel.

 When opening the cap, grasp it
firmly and turn it slowly to the left.
Do not remove the cap quickly.
Fuel may be under pressure and
spray out of the fuel filler neck,
especially in hot weather. If you
hear a hissing sound while you
are removing the cap, wait for the
sound to stop and then slowly
open the cap to prevent fuel from
spraying out and creating a fire
hazard.

Check the fuse and replace it if necessary.
Refer to "Fuses" P371. If the fuse is not
blown, have the cooling system checked
by your SUBARU dealer.
If the frequent addition of coolant is neces-
sary between vehicle service visits, it is
recommended that you have your vehicle
inspected by an authorized SUBARU
dealer to check for leaks, damage, or
looseness.■ Engine Coolant▼ Checking the coolant level1) “FULL” level mark
2) “LOW” level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW” level mark, add coolant up to the
“FULL” level mark. If the reserve tank is
empty, remove the radiator cap and refill
coolant up to just below the filler neck as
shown in the following illustration.
1) Fill up to this level.
3. After refilling the reserve tank and the
radiator, reinstall t he cap and check that
the rubber gaskets in side the radiator cap
are in the proper position.

CAUTION
 Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

▼ Approved engine oil
Always use the SUBARU approved engine oil. For fu rther details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
▼ Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
 In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommend ed viscosities and applicable temperatures.Compression ratio 12.5 : 1
