2023 NISSAN ALTIMA check oil

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marks
OB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
OA,re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
fill oil level above H (High) mark
OC.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
• Prolonged and repeated contact
with used engine oil may cause skin
cancer.
• Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand
cleaner as soon as possible.

children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by
hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket ma-
terial remaining on the sealing surface
of the engine. Failure to do so could
lead to an oil leak and engine damage. •
The dipstick must be inserted in
place to prevent oil spillage from the
dipstick hole when filling the engine
with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten addi-
tionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 f t-lb (14.7 to 20.6 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench. Do not use exces-
sive force.
Drain plug tightening torque: 22 to 29 f t-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recommended oil through the oil filler opening, and in-
stall the oil filler cap securely.
For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The
drain and refill capacity depends on the oil
temperature and drain time. Use these
specifications for reference only. Always use the dipstick to determine the proper
amount of oil in the engine.
10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required. Turn the engine off
and wait more than 15 minutes. Check
the oil level with the dipstick. Add en-
gine oil if necessary.
Af ter the operation
1. Reinstall undercover in reverse order ofremoval.
2. Lower the vehicle carefully to the ground.
3. Reset the oil control system (if so equipped) and oil and filter maintenance
reminder. For additional information,

9-4Maintenance and schedules

Exhaust system:Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, see “Exhaust gas (carbon monox-
ide)” (P. 5-4).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean those areas where mud and dirt may accu-
mulate. For additional information, see the
“Cleaning exterior” (P. 7-2).
Windshield-washer fluid*:
Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, see “Gen-
eral maintenance” (P. 9-2).
Items marked with

cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending 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 people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 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 per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed 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.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi or
door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy or salt spread roads.
• Using a car-top carrier.
If your vehicle is mainly operated under the
severe conditions, follow the severe use
maintenance intervals shown in the main-
tenance schedule.
