 Diesel fuel that contains 50 ppm or less of sulfur
Oil grade: ACEA C2, B1, API CF-4 or CF
Recommended viscosity (SAE):
Temperature range anticipated before
next oil change
Oil viscosity (0W-30 is explained here as an example):
• The 0W in 0W-30 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 30 in 0W-30 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.

SAE 0W-30 is filled into your
Toyota vehicle at manufacturing,
Preferred
and the best choice for good fuel
economy and good starting in
cold weather.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 5W-30 or 0W-30
engine oil is recommended.
