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: API SN/RC multigrade engine oil
Recommended viscosity: SAE 0W-16
SAE  0W-16  is  the  best  choice
for  good  fuel  economy  and
good starting in cold weather.
If  SAE  0W-16  is  not  available,
SAE  0W-20  oil  may  be  used.
However,  it  must  be  replaced
with  SAE  0W-16  at  the  next  oil
change.
Oil viscosity (0W-16 is expl ained here as an example):
• The  0W  in  0W-16  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  16  in  0W-16  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.
