Adding Equipment to the Outside of

Your Vehicle

Things you might add to the outside of your vehicle can

affect the airﬂow around it. This may cause wind

noise and affect windshield washer performance. Check

with your dealer before adding equipment to the

outside of your vehicle.

Fuel

The 8th digit of your vehicle identiﬁcation number (VIN)

shows the code letter or number that identiﬁes your

engine. You will ﬁnd the VIN at the top left of the

instrument panel. See Vehicle Identiﬁcation Number

(VIN) on page 5-86.

Gasoline Octane

If your vehicle has the 3800 V6 engine, use regular

unleaded gasoline with a posted octane of 87 or higher.

If the octane is less than 87, you may get a heavy

knocking noise when you drive. If this occurs, use a

gasoline rated at 87 octane or higher as soon as

possible. Otherwise, you might damage your engine. A

little pinging noise when you accelerate or drive

uphill is considered normal. This does not indicate a

problem exists or that a higher-octane fuel is necessary.

If you are using 87 octane or higher-octane fuel and

hear heavy knocking, your engine needs service.

If your vehicle has the 3.6L V6 engine, use regular

unleaded gasoline with a posted octane of 87 or higher.

However, for best performance and for trailer towing,

you may wish to use middle grade or premium unleaded

gasoline. If the octane is less than 87, you may get a

heavy knocking noise when you drive. If this occurs, use

a gasoline rated at 87 octane or higher as soon as

possible. Otherwise, you might damage your engine.
