Lubrication method | Forced lubrication | Oil pump | Pump type | Trochoid type | Number of teeth | Inner rotor | 7 | Outer rotor | 8 | Outer rotor diameter - Thickness | mm (in) | 76 - 30.2 (2.99 - 1.19) | Performance (Oil temperature 80°C (176°F)) | 600 r/min | Discharge pressure | kPa (kg/cm2, psi) | 98 (1.0, 14) | Discharge rate | L (US qt, Imp qt)/min | 5.0 (5.3, 4.4) or more | 6,000 r/min | Discharge pressure | kPa (kg/cm2, psi) | 392 (4.0, 57) | Discharge rate | L (US qt, Imp qt)/min | 82.8 (87.5, 72.9) or more | Oil filter | Filter type | Full-flow filter type | Filtration area | cm2 (sq in) | 1,300 (201.5) | By-pass valve opening pressure | kPa (kg/cm2, psi) | 160 (1.63, 23.2) | Outer diameter - Width | mm (in) | 80 - 75 (3.15 - 2.95) | Installation screw specifications | M 20 - 1.5 | Oil pressure switch | Type | Immersed contact point type | Operating voltage — power consumption | 12 V — 3.4 W or less | Warning light operating pressure | kPa (kg/cm2, psi) | 14.7 (0.15, 2.1) | Proof pressure | kPa (kg/cm2, psi) | 980 (10.0, 142) | Engine oil | Total capacity (at overhaul) | L (US qt, Imp qt) | 7.8 (8.2, 6.9) | When replacing engine oil and oil filter | L (US qt, Imp qt) | 6.5 (6.9, 5.7) | When replacing engine oil only | L (US qt, Imp qt) | 6.3 (6.7, 5.5) |
CAUTION: It is acceptable to fill an engine with oil of another brand when replacing the oil, but make sure to use the following engine oil specified by Subaru. Engine oil standard | Those with SN “Resource Conserving” logo in case of API standard. | or | Those with GF-5 “starburst mark” displayed on top of the container in case of ILSAC standard. | SAE viscosity No. | |
NOTE: The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition. |
