S-OIL base oil’s applications in Engine oils
Very high viscosity index of aramcoULTRA series ensures adequate engine lubrication under wide range of temperatures and consequently improves fuel economy.
Low CCS viscosity ensures low temperature startability and fuel economy for wide range multi-grade engine oils.
Low volatility ensures low oil consumption and satisfies the requirements for the stringent engine oil specifications like ILSAC .GF-4(15% max) or updated ACEA As/B/Cs(13% max). (In addition, aramcoULTRA series can also be used as a correction fluid to be applied in combination with conventional GroupⅠ or GroupⅡ base oils to meet these specifications).
Excellent oxidation stability ensures longer drain intervals. Recent engine oil specifications like ILSAC GF-4 and upcoming GF-5 add requirements for aged oils, which call for better oxidation stability.
S-OIL Base Stocks Applications in Industrial Lubricants
·Excellent low temperature performance and high VI of aramcoULTRA series guarantees sufficient gear lubrication and low temperature fluidity.
·Excellent oxidation stability ensures longer drain interval for turbine and hydraulic applications.
·Higher flash points and less fume ensures safer and cleaner operation for metalworking applications.
S-OIL base oil’s applications in white mineral oils
·White mineral oils:
UV absorbance (DMSO method) and carbonizable substances test result show only a traceable amount of aromatics present in the aramcoULTRA series, which ensures excellent stability as white mineral oils. |
