Lubricant and Recommended Specification of Fuel Lubricant for diesel It is better to use the CD Class 15W/40 diesel oil produced by China Petrochemical General Company or use the APICC/CD Class 15W-40 thickened engine oil of America Petroleum Association. The sulphate content in the oil should not exceed 1.85%. Attention: When the ambient temperature is keeping below -5 , use the light weight CD Class 5W-30 engine oil will facilitate the start. Continuously use the low viscidity engine oil will increase the wear of engine. Use in the hyperborean area:
If one engine is always runs under the ambient temperature of below -23 and there has no warming measures when it is under non-running status, the use of CS Class engine oil should meet the additional requirements below: Parameters (Test Method) Description Viscidity Under -35 , max. 10,000 MpaꞏS Under 100 , min. 5.6 mm 2 /s Freezing point (American Society of Testing Materials: ASTM D-97) At least lower 5 than the expected minimum ambient temperature The suitable engine oil will include comprehensive composition and it should in conformity with the product of 5W-20 or 5W-30. Fuel: Warning: Mix the gasoline or alcohol with diesel oil is prohibited and such mixture will cause the explosion.
It is suggest using the light diesel oil from China Petrochemical General Company. To adopt such fuel will make the property of diesel under the optimal status. When the working temperature is below 0 , select the suitable grade of light diesel oil based on the specific local air temperature. According to the air temperature, the lower-temperature light diesels that can select to use are RC-10, RC-20, RC-30, etc. The viscidity of oil should be kept over 1.3 centipoises to supply sufficient lubrication with the fuel system. 20-17
