2020 NISSAN ALTIMA technical specifications

CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
WARNING
∙ Prolonged and repeated contact withused 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.
∙ Keep used engine oil out of reach of 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 mate-
rial 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 dip-
stick 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 ad-
ditionally 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
excessive force.
Drain plug tightening torque: 22 to 29 f t-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recom- mended oil through the oil filler open-
ing, and install the oil filler cap securely.
For additional information about drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual. The drain and refill ca-
pacity depends on the oil temperature and
drain time. Use these specifications for ref- erence only. Always use the dipstick to de-
termine 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 mainte-
nance reminder. For additional infor-
mation, refer to "Vehicle information
display" in the "Instruments and con-
trols" section of this manual.
∙ Dispose of waste oil and filter properly.
∙ Check your local regulations.

FUEL RECOMMENDATION
Use unleaded regular gasoline with an oc-
tane rating of at least 87 AKI (Anti-Knock
Index) number (Research octane number
91).
CAUTION
∙ Only vehicles with the E-85 filler doorlabel can operate on E-85. Fuel system
or other damage can occur if E-85 is
used in vehicles that are not designed
to run on E-85.
∙ Using a fuel other than that specified could adversely affect the emission
control system, and may also affect
the 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 containing more
than 15% ethanol can adversely affect
the emission control devices and sys-
tems of the vehicle. Damage caused
by such fuel is not covered by the
NISSAN New Vehicle Limited Warranty.
∙ Do not use fuel that contains the oc- tane booster methylcyclopentadienyl
manganese tricarbonyl (MMT). Using
fuel containing MMT may adversely
affect vehicle performance and ve-
hicle emissions. Not all fuel dispens-
ers are labeled to indicate MMT con-
tent, so you may have to consult your
gasoline retailer for more details.
Note that Federal and California laws
prohibit the use of MMT in reformu-
lated 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 percentage
for that region.
Gasoline specifications
NISSAN 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 con-
trol system and vehicle performance. Ask
your service station manager if the gaso-
line meets the WWFC specifications.
Reformulated gasoline
Some fuel suppliers are now producing re-
formulated gasolines. These gasolines are
specially designed to reduce vehicle emis-
sions. NISSAN supports efforts towards
cleaner air and suggests that you use re-
formulated gasoline when available.
