Aftermarket fuel additives

NISSAN does not recommend the use of any

aft ermarket fuel additive s (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 tips

Using unleaded gasoline with an octane

rating lower than recommended can cause

persistent, heavy “spark knock”. (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 spa rk

knock, after-run and/or overheating, which may

cause excessive fuel consumption or engine

damage. If any of the above symptoms are

encountered, 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.

CAUTION

. Your vehicle is not designed to run

on E-85 fuel. Using E-85 fuel in a

vehicle not specifically designed for

E-85 fuel can damage fuel system

components and is not covered by

the NISSAN new vehicle limited

warranty.

. E-85 is a mixture of approximately

85% fuel ethanol and 15% unleaded

gasoline.

. U.S. government regulations require

ethanol dispensing pumps to be

identified by a small, square, orange

and black label with the common

abbreviation or the appropriate per-

centage for that region.
