Oil specially used for gasoline/CNG double-fuel taxies

The invention relates to the technical field of lubricating oil research and development and particularly relates to oil specially used for gasoline/CNG double-fuel taxies. The oil includes, by weight, 35-42 parts of 150N base oil, 50-58 parts of 500N base oil, 6.4-7.5 parts of a composite additive, 0.20-0.3 part of an antioxidant additive, 0.73-1.0 part of a tackifier and 0.2-0.3 part of a pour point depressant. The oil can improve oxidation resistance and nitration resistance of oil products, can reduce generation of sediments, and can prolong an oil change period from original 5000 km to 10000 km. 本发明属于润滑油研发技术领域，特别涉及种汽油/CNG双燃料出租车专用油。种汽油/CNG双燃料出租车专用油，由按重量份的以下组分组成：150N基础油35-42份、500N基础油50-58份、复合添加剂6.4-7.5份、抗氧添加剂0.20-0.3份、增粘剂0.73-1.0份和降凝剂0.2-0.3份。本发明的汽油/CNG双燃料出租车专用油可以提高油品的抗氧化、抗硝化能力，减少沉积物产生；可以延长换油周期，从原5000公里延长至10000公里。
