OWNER MAINTENANCE
6-6 CAUTION: The oil being drained from the engine will be hot. Care should be exercised to prevent scalding.
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 contain approximately 0.5 litres of oil and this should be 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 and then 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 no oil leaks exist. Turn off the engine and after a couple minutes, recheck the oil level.
WARNING: Prolonged and repeated contact with used engine oils may result in serious skin disor- ders including dermatitis and cancer. Avoid contact with skin as far as possible and al-

ZG030E1-A 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 oil consumption 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 when a piston moves downwards in the cylinder. High negative pressure generated during en- gine operation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustion gases 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. The engine oil is more consumed under se- vere driving conditions such as high speeds and frequent acceleration and deceleration than normal driving condition.
