Aftermarket fuel additivesGUID-04BFD2FB-84A2-41F8-AF3C-C293779408D6NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tipsGUID-F6EBBEDD-0810-4EB3-B998-76639DC8605AUsing unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy ªspark knockº. (Spark
knock is a metallic rapping noise.) If
severe, this can lead to engine damage. If
you detect a persistent heavy spark knock
even when using gasoline of the stated
octane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, have a NISSAN dealer correct
the condition. Failure to correct the condi-
tion is misuse of the vehicle, for which
NISSAN is not responsible.
Incorrect ignition timing will result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms areencountered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

Selecting the correct oilGUID-9E90D203-83D7-49ED-A3A8-D5BEBEC09FACIt is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance, see
ªCapacities and recommended fluids/lubricantsº
(P.9-2) . NISSAN recommends the use of an
energy conserving oil in order to improve fuel
economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval
Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API
certification mark on the front of the container.
Oils which do not have the specified quality
label should not be used as they could cause
engine damage.
Oil additivesGUID-BF1C00B1-1B2B-428D-B663-357F2194BB2FNISSAN does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used and
maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
