| No. | Technical Index | Note |
| 1 | Kinematic Viscosity (40℃) | Unit: mm²/s; Measures oil fluidity, core basic indicator |
| 2 | Kinematic Viscosity (100℃) | Unit: mm²/s; Reflects oil fluidity and lubrication performance at high temperatures |
| 3 | Viscosity Index (VI) | Dimensionless; Measures the stability of oil viscosity with temperature, the higher the value, the better the stability |
| 4 | Flash Point (Open Cup) | Unit: ℃; Measures oil fire safety to prevent ignition at high temperatures |
| 5 | Pour Point | Unit: ℃; Measures oil low-temperature fluidity, determining applicability in low-temperature environments |
| 6 | Density (20℃) | Unit: kg/m³; The ratio of oil mass to volume, used for measurement and component analysis |
| 7 | Water Content | Unit: % (mass fraction); Control water content in oil to avoid corrosion of engine components |
| 8 | Mechanical Impurities | Unit: % (mass fraction); Control impurity content to prevent wear of engine cylinders and bearings |
| 9 | Total Acid Number (TAN) | Unit: mgKOH/g; Measures the content of acidic substances in oil, reflecting antioxidant degradation ability |
| 10 | Total Base Number (TBN) | Unit: mgKOH/g; Core index of gas engine oil, neutralizes acidic substances generated by gas combustion and extends oil change cycle |
