摘　　要：文章主要对国内汽油机油换油标准进行了介绍,指出已有的国标GB/T 8028-1994已不能满足国内高档润滑油产品换油需求。根据SJ汽油机油在不同车型上的试验结果和国内汽车使用的实际情况对SJ汽油机油的换油指标进行了确认和修订。相比GB/T 8028-1994,新标准GB/T 8028-2010增加了闭口闪点、燃油稀释、碱值、铜元素和硅元素等控制项目,删除了开口闪点控制项目。The oil change standard for the domestic gasoline engine oil was described in this paper. It was pointed out that the current GB/T 8028 - 1994 could not meet the oil change requirements for high - grade lubricants. Based on the experi- mental results of SJ gasoline engine oil on different types of vehicles and the practical utilization situation of domestic vehi- cles, the oil change standard of SJ gasoline engine oil was confirmed and revised. Compared with GB/T 8028 - 1994, closed flash point, fuel dilution, base number, copper element and silicon element etc. were added and the open cup flash point was deleted in the new GB/T 8028 -2010.
