最新油价消息
5月12日,前9个工作日,预计成品油将下调约85元/吨,折算为0.07-0.08元/升!此轮油价调整将开启——周一(13号)晚上12点
按家用车50升油箱计算,加满一箱92号汽油将少花3.5元左右!
还有1天国内油价将出现2019年油价调整周期内,第一次下调,加油的朋友们可以等一下!
请转发朋友圈通知亲朋好友
油价要降了!
(国内油价将统计10个工作日,累积上涨或下跌超过50元/吨,全国站油将启动调价,否则不作调整,涨跌幅将会累积到下一轮计价周期中。)
油价迎来喜大普奔的好消息
今天的交广汽车小课堂
再和大家说说爱车“机油”的哪些事
@所有车主
都该懂的机油知识大全!
1机油颜色的深浅能反映机油的性能吗?机油颜色取决于基础油及添加剂的配方,不同的基础油和添加剂配方会使机油表现出不同深浅的颜色。
机油的性能是通过一系列发动机台架试验以及实车路试来评定的,这些测试从氧化、腐蚀、沉积物、粘环、油泥、擦伤、磨损等多个方面来测试机油的性能。不能单靠颜色深浅辨识哦!
易变黑的机油就一定不好吗?不一定,有些优良的机油含有能够溶解发动机内部积碳的添加剂,所以容易变黑,但是对机油的性能没有影响。
2为什么要定期更换机油?机油在运行中会逐渐变质,主要原因有:
① 燃烧副产物:如水分、酸性物质、烟炱、积碳等;
② 燃油稀释;
③ 机油本身的高温氧化变质;
④ 灰尘及金属颗粒。
这些物质都容纳在机油中,同时,机油中的添加剂也会随着使用过程不断消耗。不按期更换机油,会显著降低机油对发动机抗磨的保护作用。更换机油不但可以排出油里面的污染物,还可保证机油中的成分保持在合理水平。
3换机油时,为什么放出来的机油很稀?换机油时通常是在热车状态下进行,机油粘度是随着温度升高而下降的,因此换出来温度较高的机油,其粘度要比常温下的粘度要稀,这属于正常现象。
4如何选择机油?
① 根据车厂或服务站推荐;
② 根据车况 ;
③ 根据环境温度。
5如何检查在用机油的质量状况?
外观:
① 油样呈乳白色或呈雾状,表明机油进了水;
② 油样变为灰色,可能被汽油所污染;
③ 变为黑色,燃料不完全燃烧的产物所引起。
气味:
① 出现刺激性气味,表明机油被高温氧化;
② 很重的燃油味,表明被燃油严重稀释(用过的机油少量燃油味正常)。
6天气变热了 机油要更换吗?记住两个数字:
距离上次换机油,
行驶不到5000公里(矿物机油)
或6个月
不管天气寒冷还是炎热都不需要再更换机油哦
不过,如果你的机油灯亮了
就说明润滑系统油压不足
需要检查更换机油哦
每一个“在看”
都是对降油价的支持!
