Fuel information
■Gasoline quality
In very few cases, driveability problems may be caused by the b rand of gaso-
line  you  are  using.  If  driveability  problems  persist,  try  changing  the  brand  of
gasoline. If this does not correct the problem, consult your To yota dealer.
■ Recommendation of the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline that contains detergent a dditives to
avoid the build-up of engine deposits.
● All  gasoline  sold  in  the  U.S.A.  contains  minimum  detergent  addi tives  to
clean and/or keep clean intake systems, per EPA’s lowest additi ves concen-
tration program.
● Toyota  strongly  recommends  the  use  of  Top  Tier  Detergent  Gasoli ne.  For
more  information  on  Top  Tier  Detergent  Gasoline  and  a  list  of  m arketers,
please go to the official website www.toptiergas.com.
■ Recommendation of the use  of low emissions gasoline
Gasolines  containing  oxygenates  such  as  ethers  and  ethanol,  as  well  as
reformulated gasolines, are available in some cities. These fue ls are typically
acceptable for use, providing they meet other fuel requirements .
Toyota  recommends  these  fuels,  since  the  formulations  allow  for   reduced
vehicle emissions.
You must only use unleaded gasoline.
Select octane rating 87 (Research Octane Number 91) or higher.
Use  of  unleaded  gasoline  with  an  octane  rating  lower  than  87
may  result  in  engine  knocking.  Persistent  knocking  can  lead  to
engine damage.
At minimum, the gasoline you use should meet the specifications  of
ASTM D4814 in the U.S.A..
