Group II Base Oil (N70, N150, N500, N600)

Hydroprocessed low-sulphur base oils for modern engine oils

Group II base oil is made by hydroprocessing, not solvent refining. API 1509 Appendix E defines it as 90% or more saturates, 0.03% sulphur or less, and viscosity index 80 to under 120. Grades are named N70, N100, N150, N220, N500 and N600, or by the refiner's own code. Chevron's Group II test data are a good reference: 100R (Group II+) at 21.2 cSt at 40 °C and 4.4 cSt at 100 °C, VI 117; 220R at 42.7 and 6.6 cSt, VI 106, flash 230 °C; 600R at 108 and 12.2 cSt, VI 103, flash 270 °C, pour -17 °C. All three show sulphur under 10 ppm, saturates above 99% and a colour of L0.5. Chevron's specification sheet sets 150R at 5.0-5.4 cSt at 100 °C with VI 100 minimum, and 600R at 11.7-12.9 cSt with VI 95 minimum.

Blenders use Group II for modern passenger-car and heavy-duty engine oils, low-SAPS oils, and hydraulic, turbine and compressor oils that need long oxidation life. A COA tells Group I from Group II in three lines: sulphur (Group II is 0.03% or less, often a few ppm), saturates (90% or more), and colour (near water-white). A Group I SN grade shows higher sulphur and a darker colour. CBIL is a commodity brokerage company and brokers Group II base oils from refineries in South Korea, Singapore, the USA, Spain, Bahrain, Saudi Arabia (Red Sea side), India, Taiwan and Thailand, and from UAE blending hubs. Each lot ships against the refinery COA and SGS or Intertek inspection at load, in bulk parcels, ISO tanks, flexitanks of about 20-22 t or new steel drums of 180-210 kg. Send the grade, quantity, packing, destination port and payment terms.
