Engine Oil Pressure: Testing and Inspection
1. Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
Oil grade: API SH, Energy-Conserving II multigrade engine oil or ILSAC multigrade engine oil. Recommended viscosity is as shown in the
illustration with SAE 5W-30 being the preferred engine oil.
2. Check engine oil level.
(a) The engine oil level should be between the "L" and "F" marks on the dipstick.
If low, check for leakage and add oil up to OFF mark.
CAUTION:
-
Do not fill with engine oil above the "F" mark.
-
The oil dipstick must be inserted so that the portion painted black faces the direction shown in the illustration.
(b) The engine oil level should be between the "L" and "F" lines.
If low, check for leakage and add oil up to "F" line.
3. Remove oil pressure switch, and install oil pressure gauge.
4. Warm up engine.
Allow the engine to warm up to normal operating temperature.
5. Check oil pressure.
Oil pressure:
At idle: 29 kPa (0.3 kg/cm sq., 4.3 psi) or more
At 3,000 rpm: 245 kPa (2.5 kg/cm sq., 36 psi) or more
