Oil used in the engine should have API classification and Proper SAE Engine Oil according to the ambient
temperatures as shown below:
A
Recommended API classification
Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil according
to the engine type (with internal EGR, external EGR or non-EGR) and the Fuel Type Used : (Ultra Low Sulfur or
High Sulfur Fuels).
EGR: Exhaust Gas Re-circulation
Above 25°C (77°F)
SAE30, SAE10W-30 or 15W-40
-10 to 25°C (14°F to 77°F)
SAE10W-30 or 15W-40
Below -10°C (14°F)
SAE10W-30
Fuel type
Engine oil classification (API classification)
Engines with non-EGR
Engines with internal EGR
Engines with external EGR
High Sulfur Fuel
[0.05 % (500 ppm)
Sulfur Content <
0.50 % (5000 ppm)]
CF
(If the "CF-4, CG-4, CH-4 or CI-4" engine oil is used
with a high-sulfur fuel, change the engine oil at
shorter intervals. (approximately half))
---
Ultra Low Sulfur Fuel
[Sulfur Content <
0.0015 % (15 ppm)]
CF, CF-4, CG-4, CH-4 or CI-4
CF or CI-4
(Class CF-4, CG-4 and CH-4 engine, oils
cannot be used on EGR type engines.)
