Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle.
To help keep the engine clean
and maintain optimum vehicle
performance, we recommend
the use of gasoline advertised as
TOP TIER Detergent Gasoline.
Look for the TOP TIER label on
the fuel pump to ensure gasoline
meets enhanced detergency
standards developed by auto
companies. A list of marketers
providing TOP TIER Detergent
Gasoline can be found at
www.toptiergas.com.
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85).
See
Fuel E85 (85% Ethanol) on
page 9
‑
38
. For all other vehicles,
use only the unleaded gasoline
described under
Recommended
Fuel on page 9
‑
35
.
Recommended Fuel
Use regular unleaded gasoline
with a posted octane rating of 87 or
higher. If the octane rating is less
than 87, an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon
as possible. If heavy knocking is
heard when using gasoline rated
at 87 octane or higher, the engine
needs service.
