Engine Oil: Service and Repair

Engine Oil 

REPLACEMENT 

1) Open the engine oil filler cap for quick draining of the engine oil.

2) Drain the engine oil by loosening engine oil drain plug.
3) Replace the drain plug gasket.

4) Tighten the engine oil drain plug after draining engine oil.

Tightening torque: 44 Nm (4.5 kgf-m, 32.5 ft. lbs.) 

5) Fill engine oil through the filler pipe up to upper point on level gauge. Make sure that the vehicle is placed level when checking oil level. Use the

engine oil of proper quality and viscosity, selected in accordance with the table in figure.
Recommended oil API classification SL, SJ or SH grade oil with the words "Energy Conserving" or "Energy Conserving II", or the new API mark
indicated on the container (if SL or SJ grade oil is unavailable, use SH or SO grade oil).
Engine oil capacity: (Non-turbo model)
Upper level 4.0 liters (4.2 US quarts 3.5 Imp quarts) 
Lower level 3.0 liters (3.2 US quarts 2.6 Imp quarts) 

Engine oil capacity: (Turbo model)
Upper level 4.5 liters (4.8 US quarts 4.0 Imp quarts) 
Lower level 3.5 liters (3.7 US quarts 3.1 Imp quarts) 
Oil of a proper viscosity ensures good cold and hot starting by reducing viscous friction and thus increasing cranking speed.
