7-3. Do-it-yourself maintenance
■Adding engine oil
If  the  oil  level  is  below  or  near
the  low  level  mark,  add  engine
oil  of  the  same  type  as  that
already in the engine.
Make  sure  to  check  the  oil  type  and  prepare  the  items  needed
before adding oil.Remove the oil filler cap by  turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap  by turning it clockwise.
■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following
situations,  oil  consumption  may  increase,  and  engine  oil  may  need  to  be
refilled in between oil maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or
after replacing the engine
● If low quality oil or oil of an inappropriate viscosity is used
● When  driving  at  high  engine  speeds  or  with  a  heavy  load,  when  towing,  or
when driving while accelerating or decelerating frequently
● When  leaving  the  engine  idling  for  a  long  time,  or  when  driving  frequently
through heavy traffic

■Engine oil selection
“Toyota  Genuine  Motor  Oil”  is  used  in  your  Toyota  vehicle.  Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
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 explained 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  viscosity  characteristic  of  the  oil when the oil is at high temperature. An oil with a higher viscosity
(one  with  a  higher  value)  may  be  better  suited  if  the  vehicle  is
operated at high speeds, or  under extreme load conditions.
How to read oil container label:
The  International  Lubricant
Specification  Advisory  Commit-
tee  (ILSAC)  Certification  Mark
is  added  to  some  oil  containers
to  help  you  select  the  oil  you
should use.
