很多车主可能都知道,根据机油的使用里程来换油,但是如果爱车平常开的少或者很长时间没开了,里程数没达到更换机油的标准,那还需要更换吗?
可以肯定的说需要更换,具体原因就先从机油更换周期的标准说起:
第一,车辆行驶里程,按照不同类型机油使用的公里数,矿物机油每5000公里一换,半合成机油每7000公里一换,全合成机油更换周期长达10000-15000公里。总之,车辆如果频繁使用,到了公里数就要及时保养。
第二,就是今天的主要话题,按时间期限来更换机油。车辆保养手册中,对于更换机油,除了里程数外,还有时间要求。比如说“5000公里或者6个月”二者先到为准,可能很多朋友对按时间更换机油没有概念,也从不知道更换机油还要按时间。
那么为什么要按时间期限来更换机油呢?
1,对于一年只开个几千公里,只用于上下班的车辆来说,机油同样随着时间的推移,会自身氧化、被污染等,使其品质下降,失去机油原有的对发动机良好的保护性能。还有机油中所含的各种添加剂是在不停消耗的。机油在使用中不停地混入气缸中燃烧的气体而生成油泥、积炭、水分、酸性氧化物等会使机油的使用性能不断的下降。所以,过了机油最佳的使用期限,会显著的降低机油对发动机的抗磨保护、抗腐蚀保护等性能。
2,如果车辆长时间不使用,也不更换机油,除了机油会变质、乳化外,由于车辆发动机长时间不运转,所以机油在重力的作用下基本已经全部回流到油底壳,发动机内部各摩擦副已经没有了油膜保护,这时候车辆第一次冷启动,会对发动机造成过度磨损。另外,长时间不使用车辆,对汽车的蓄电池、轮胎等部件都会有一定的损耗。
德国金引擎润滑油友情提示:所有车辆的保养换机油期限标准:矿物机油为5000公里或者6个月一换,半合成机油7500公里或者6个月一换,全合成机油10000公里或者一年一换,以两者先到为准。考虑到国内较拥堵的路况,及有暴力驾驶习惯的车主,可以适当提前为车辆进行保养。如果车辆长时间闲置,尽可能两至三周开一次车,这样不仅可以为电瓶充电,还可以看看轮胎有没有亏气,并且能够让机油润滑、保护发动机部件。长期旅游出差,请家人或者朋友,帮忙每周发动车辆一次,变换一下轮胎位置,防止轮胎及轮毂出现变形。
总之,机油长期不更换,会变质、乳化。所以,如果车辆行驶公里数没有到达更换机油的标准,但时间期限已经到达,是需要更换机油的。车辆其它的部件的油液也应该定期检查,老化的也要及时更换,以免车辆在使用过程中发生问题。
