Engine oil selection
“Toyota  Genuine  Motor  Oil”  is  used  in  your  Toyota  vehicle.  Use
Toyota  approved  “Toyota  Genuine  Motor  Oil”  or  equivalent  to  sat -
isfy the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE  0W-20  is  the  best  choice
for  good  fuel  economy  and
good starting in cold weather.
If  SAE  0W-20  is  not  available,
SAE  5W-20  oil  may  be  used.
However,  it  must  be  replaced
with  SAE  0W-20  at  the  next  oil
change.
Oil viscosity (0W-20 is expl ained here as an example):
• The  0W  in  0W-20  indicates  the  characteristic  of  the  oil  which allows cold startability. Oils wi th a lower value before the W allow
for easier starting of the engine in cold weather.
• The  20  in  0W-20  indicates  the  vi scosity  characteristic  of  the oil
when the oil is at high temperature. An oil with a higher visco sity
(one  with  a  higher  value)  may  be  better  suited  if  the  vehicle  i s
operated at high speeds, or un der extreme load conditions.

■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.
Fuel information
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..
