prem ium   gasoline   will  provid  e  no  benefit   over   high
quality  regu lar gasoline,  and  in som e circumstances   may
resu lt in poorer   perform ance.
ReformulatedGasoline
Many  areas   of  the  country   requ ire  the  use   of  cleaner
burning   gasoline  referred   to  as Reform ulated   Gasoline.
Reform ulated  gasoline   contains  oxygenates,   and  is  spe-
cifically  blend ed  to   red uce vehicle   emissions   and   im-
prove  air  quality.
Light spark  knock  at low  engine  speed s is not harm ful  to
you r engine.  However,   continu ed  heavy  spark  knock  at
high  speed s can  cause damage   and  immediate   service is
requ ired .
The manu  factu rer strongly  supports   the  use of  reform u-
lated  gasoline.   Prop erly  blend ed  reform ulated  gasoline
will provid  e excellent perform  ance and  durability   for the 5
engine  and  fuel  system  components.
Poor  quality  gasoline   can  cause  problem s  such  as hard
starting,  stalling  and  hesitations.   If you  experience  these
sym ptom s, try  another  brand   of gasoline  before  consid -
ering  service  for the  vehicle.
Gasoline/OxygenateBlends
Some  fuel  suppliers   blend  unlead ed  gasoline  with   oxy-
genates  such  as 10% ethanol,  MTBE, and  ETBE. Oxygen-
ates are  requ ired in  som e areas of the  country  during  the
winter   months   to  red uce  carbon   monoxid e  emissions.
Fuels  blend ed  with   these   oxygenates   may  be  used   in
you r vehicle.
Over 40 auto  manu factu rer’s world  wide have  issu ed and
end orsed  consistent   gasoline   specifications   (the  World -
wide   Fuel  Charter,   WWFC)   to  define   fuel   prop erties
necessary   to  deliver  enhanced   emissions,   perform  ance,
and  durability  for you r vehicle.  The manu factu rer recom -
mend s the  use  of gasoline   that  meets  the  WWFC speci-
fications  if they  are  available.
