Adding Equipment To The Outside Of Your Vehicle; Fuel; Gasoline Octane - Saturn 2007 Sky Owner's Manual

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 retailer before

adding equipment to the outside of your vehicle.

Fuel

Use of the recommended fuel is an important
part of the proper maintenance of your vehicle.
To help keep your engine clean and maintain
optimum vehicle performance, Saturn recommends
the use of gasoline advertised as TOP TIER
Detergent Gasoline.

Gasoline Octane

Use premium unleaded gasoline with a posted
octane rating of 91 or higher. You may also
use regular unleaded gasoline rated at 87 octane
or higher, but your vehicle's acceleration may
be slightly reduced, and you may notice a slight
audible knocking noise, commonly referred to
as spark knock. If the octane is less than 87,
you may notice 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.
If you are using gasoline rated at 87 octane
or higher and you hear heavy knocking, your
engine needs service.
