Embodiment 1
[0029] The light-duty engine oil described in this embodiment is composed of the following components in terms of weight percentage: A5 / B50W-30: 99.5%; 0.5% of non-phosphorus molybdenum salt friction reducer, and the non-phosphorus molybdenum salt friction reducer is Compound shown in formula I:
[0030]
[0031] Wherein, R is butyl.
[0032] The phosphorus content of the light-duty engine oil prepared in this embodiment is 0.107, and the molybdenum content is 0.028. The phosphorus content in the original product is 0.107, and the molybdenum content is <0.001, without increasing the phosphorus element content harmful to the three-way catalytic converter in the product. At the same time, the energy saving effect can be increased by 2%.

[0035]
[0036] Wherein, R is pentyl.
[0037] The phosphorus content of the light-duty engine oil prepared in this embodiment is 0.107, and the molybdenum content is 0.0289. The phosphorus content in the original product is 0.107, and the molybdenum content is <0.001, without increasing the phosphorus element content harmful to the three-way catalytic converter in the product. At the same time, the energy saving effect can be increased by 2%.
Embodiment 3
[0039] The light-duty engine oil described in this embodiment is composed of the following components in terms of weight percentage: A5 / B50W-30: 99.62%; 0.38% of non-phosphorus molybdenum salt friction reducer, and the non-phosphorus molybdenum salt friction reducer is Compound shown in formula I:
[0040]
[0041] Wherein, R is a hexyl group.
[0042] The phosphorus content of the light-duty engine oil prepared in this embodiment is 0.107, the molybdenum content is 0.032, and the phosphorus content in the original product is 0.107, and the molybdenum content is <0.001, without increasing the phosphorus content harmful to the three-way catalytic converter in the product, At the same time, the energy saving effect can be increased by 2%.
