6-1. Specifications
1AD-FTV engine with DPF catalytic converter, 2AD-FTV and 2AD-
FHV engines
Oil grade: ACEA C2
NOTICE
Using engine oil other than ACEA C2 may damage the catalytic converter.
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.
