摘要/Abstract

摘要： 为了考察自主研发的GF-5 5W-30生物基汽油机油在丰田普瑞维亚轿车的行车适用性，进行两个阶段（5000 km为A阶段、10 000 km为B阶段）行车试验，并在不同行驶里程下进行取样分析。主要依据国家标准GB/T 8028—2010《汽油机油换油指标》对GF-5 5W-30生物基汽油机油样品的运动黏度、酸值、碱值、正戊烷不溶物、金属含量、水分等指标进行分析。结果表明：在两个阶段的行车试验后，GF-5 5W-30生物基汽油机油的运动黏度（100 ℃）变化率小于±3%，酸值增长值不大于1.76 mgKOH/g，碱值与酸值差值大于2.9 mgKOH/g，正戊烷不溶物质量分数不大于0.1%，金属质量分数增长值不大于9 μg/g，水质量分数不大于2 000 μg/g，各项指标均在国家标准GB/T 8028—2010的技术要求范围内。GF-5 5W-30生物基汽油机油性能优异，完全可以满足车辆的使用要求，换油期达到10 000 km时仍有余量。

Abstract: In order to investigate the driving applicability of independently developed GF-5 5W-30 bio-based gasoline oil in Toyota Privia vehicle, two stages ofroad test(5 000 km for stage A and 10 000 km for stage B) were carried out, and oil samples were extracted and analyzed at different mileage according to the national standard GB/T 8028—2010 "Criteria for changing of gasoline engine oil" on the kinematic viscosity, acid value, base value, n-pentane insoluble matter, metal content, moisture and other indexes of GF-5 5W-30 bio-based gasoline engine oil samples. The results showed that after the two-stage road test, the kinematic viscosity (100 °C) change rate of GF-5 5W-30 bio-based gasoline engine oil was less than ±3%, acid value growth was no more than 1.76 mgKOH/g, the difference of base value and acid value was greater than 2.9 mgKOH/g, n-pentane insoluble matter growth was no more than 0.1%, metal content growth was no more than 9 μg/g, water content was no more than 2 000 μg/g, all the indicators were within the range of technical requirements of the national standard GB/T 8028—2010. GF-5 5W-30 bio-based engine gasoline oil had excellent performance and could meet the requirements of the vehicle. There was still a margin when the oil change period reaches 10 000 km.
