Lubrication System On-Vehicle Inspection

Warm up and stop the engine, then wait for 5 minutes.

Check that the engine oil level is between the low level and full level marks on the level gauge.
If low, check for leakage and add oil up to the full level mark.

NOTICE:

Do not fill with engine oil to above the full level mark.

HINT:

Engine oil is always being consumed when driving the vehicle.

Generally, engine oil is consumed at a rate of 1 liter every 3000 km, or 1 US qts. every 2000 miles.

In the following situations, oil consumption may increase and it may be necessary to add oil between maintenances.

1. The engine is new.
   
2. The oil quality is poor or the viscosity is inappropriate.
   
3. The engine speed or load is high, the vehicle is towing something or the vehicle is being accelerated and decelerated frequently.
   
4. The engine is idled for a very long time or the vehicle is frequently driven in traffic.
   

Check the oil for deterioration, water, discoloring or thinning.
If the quality is visibly poor, replace the oil.

Remove the oil pressure switch (COROLLA_ZRE142 RM000003D7I009X.html).

Install the oil pressure gauge.

Warm up the engine.

Check the oil pressure.

Oil Pressure:

At Idle	At 3000 rpm
29 kPa (0.3 kgf/cm2, 4.3 psi) or more	170 to 300 kPa (1.7 to 3.1 kgf/cm2, 24 to 44 psi)

If the oil pressure is not as specified, check the oil pump (COROLLA_ZRE142 RM000001R0K02KX.html).

Remove the oil pressure gauge.

Install the oil pressure switch (COROLLA_ZRE142 RM000003D7F009X.html).
