6-6 WARNING: The oil being drained from the engine will behot. Care should be exercised to preventscalding.
4. When the oil has drained from the sump,
replace the drain plug using a new washer ensuring that the plug is not over tightened.
Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L)4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by rotating counterclock- wise, using a proprietary oil filter removal toolif necessary. Note that the oil filter will containapproximately 0.5 litres of oil and this shouldbe collected in a suitable receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotating clock-wise until the filter contacts the mounting andthen a further one half turn. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure that nooil leaks exist. Turn off the engine and after acouple minutes, recheck the oil level.
WARNING:Prolonged and repeated contact with usedengine oils may result in serious skin disor-ders including dermatitis and cancer. Avoidcontact with skin as far as possible and al-

G350A01A-GAT ENGINE OIL CONSUMPTION Function of engine oil Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption It is normal that an engine should consume some engine oil while normal driving. The cause of oilconsumption in a normal engine are as follows;
o Engine oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is left on the cylinder wall whena piston moves downwards in the cylinder.High negative pressure generated during en-gine operation sucks some of the oil into thecombustion chamber.This oil with some oil of the cylinder wall isburned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc.More engine oil may be consumed undersevere driving conditions such as high speeds,frequent acceleration and deceleration, com-pared to normal driving.
