ENGINE OIL
Inspection
ENGINE OIL LEVELNOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop it and allow 10 minutes before checking.
- 1.Pull out oil level gauge and wipe it clean.
- 2.Insert oil level gauge and check the engine oil level is within the range (A) shown in the figure.
- 3.If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge (1) with its tip aligned with oil level gauge guide.| 2 | : Radiator cap |

ENGINE OIL APPEARANCE- Check engine oil for white turbidity or heavy contamination.
- If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.
ENGINE OIL LEAKAGECheck for engine oil leakage around the following areas:
- Oil pans (lower and upper)
- Oil pan drain plug
- Oil pressure switch
- Oil level sensor
- Oil temperature sensor
- Oil filter
- Oil filter bracket
- Valve timing control cover
- Intake valve timing control solenoid valve
- Mating surface between cylinder head and rocker cover
- Mating surface between front timing chain case and rear timing chain case
- Mating surface between rear timing chain case and cylinder head
- Mating surface between rear timing chain case and cylinder block
- Mating surface between rear timing chain case and oil pan (upper)
- Mating surface between cylinder block and cylinder head
- Mating surface between lower cylinder block and cylinder block
- Crankshaft oil seals (front and rear)
- Camshaft position sensor (PHASE)
- Turbo charger
OIL PRESSURE CHECK■ WARNING ■
- Be careful not to get burned, as engine oil may be hot.
- Oil pressure check should be done in “Parking position”.
- 1.Check the engine oil level. Refer to Inspection.
- 2.Remove engine undercover with power tool.
- 3.Disconnect harness connector at oil pressure switch, and remove oil pressure switch.

■ CAUTION ■
Never drop or shock oil pressure switch.- 4.Install the oil pressure gauge [SST: ST25051001 (J25695‐1)] (A) and hose [SST: ST25052000 (J25695‐2)] (B).
- 5.Start the engine and warm it up to normal operating temperature.
- 6.Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.| Engine oil pressure | : Refer to Engine Oil Pressure (GT-R certified NISSAN dealer). |
If difference is extreme, check engine oil passage and oil pump for engine oil leakage.
- 7.After the inspections, install oil pressure switch as follows:
-
(1)Remove old liquid gasket adhering to oil pressure switch and the mating surface.
-
(2)Apply liquid gasket and tighten oil pressure switch to the specification.Use Genuine RTV Silicone Sealant or equivalent. Refer to Recommended Chemical Products and Sealants.
| Tightening torque | : Refer to Exploded View (GT-R certified NISSAN dealer). |
-
(3)After warming up engine, check there is no leakage of engine oil with running engine.
Draining
■ WARNING ■
- Be careful not to get burned, as engine oil may be hot.
- Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
- 1.Warm up the engine, and check for engine oil leakage from engine components. Refer to Inspection.
- 2.Stop the engine and wait for 10 minutes.
- 3.Loosen oil filler cap.
- 4.Remove undercover with power tool.
- 5.Remove drain plug (1) and then drain engine oil.

Refilling
- 1.Install drain plug with new washer. Refer to Exploded View (GT-R certified NISSAN dealer).
■ CAUTION ■
Be sure to clean drain plug and install with new washer.| Tightening torque | : Refer to Exploded View (GT-R certified NISSAN dealer). |
- 2.Refill with new engine oil.Engine oil specification and viscosity: Refer to Fluids and Lubricants
- When filling engine oil, never pull out oil level gauge.
- The refill capacity depends on the engine oil temperature and drain time. Use these specifications for reference only.
- Always use oil level gauge to determine the proper amount of engine oil in engine.
| Engine oil capacity | : Refer to Periodical Maintenance Specification. |
■ CAUTION ■
- 3.Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
- 4.Stop the engine and wait for 10 minutes.
- 5.Check the engine oil level. Refer to Inspection.
