你的车子选对引擎润滑油了吗?

很久很久以前,有一个人的Audi TT行驶了130,000 km都没换润滑油。

在买新车时,商家通常都会为你提供全套的保养套餐,所以你几乎不用为使用哪种引擎润滑油做选择。购买一辆全新的Perodua AxiaPerodua就会确保车子在保固期内都使用品牌认证的润滑油。对于其它品牌的车子也是一样,他们的服务中心通常都会采用PetronasShell的润滑油。

就算你去当地的修车店,他们通常也都是某个引擎润滑油品牌的官方经销商。需要去考虑车子该使用哪种引擎润滑油的,通常都是那些车子已经过了保固期的车主、二手车车主,或者是那些更关心车子的人。

这不是选错润滑油的结果,而是缺少保养的结果

Q:那么,你要如何选择正确的引擎润滑油呢?

A:这个问题很简单,参考车子的说明书,并购买正品润滑油就可以了,网路上总能找到免费的PDF文件的。

一辆新潮的车,有着新潮的引擎和新潮的车门

除非你的车跟Mazda RX-8一样搭载了一具新潮的引擎,通常情况下,依照用户说明书来选择引擎润滑油的等级就够了。接下来谈到的,都是对这个话题的进一步阐述而已。

Q:10W-40、10W-30和5W-40都是什么?

 

小知识:10W-40中的“W”代表着冬天(Winter)

A:在我们说“W”之前,先来谈谈这些数字吧,它们代表着润滑油的粘度数字越大,引擎润滑油的粘度也就越高。如果你还不知道粘度是什么,那么简单的说,油漆的粘度就要比水的大

将油漆倒出来需要更长的时间,就是这样

##W-30的粘度比##W-20大,##W-40的粘度比##W-30大。

Q:“W”到底代表什么?

A:冬天,没骗你。

Q:粘度重要吗?

A:重要,因为粘度的衰减决定了你的保养周期。

在寒冷的环境中,15W-##的粘度要比10W-##大,而10W-##的粘度要比5W-##大。

冬季乐园

Q:“W”的数字在马来西亚有用吗?

A:没有,“W”数字代表的是引擎润滑油在寒冷气温下的工作性能。

Q:那10W-40就要比10W-30差吗?

A:并不是,你应该使用的引擎润滑油粘度取决于你的引擎配合精度。不同的引擎,配合精度也不尽相同,因此也应该使用不同等级的引擎润滑油。

Q:什么是矿物润滑油、半合成润滑油和全合成润滑油?

A:它们都是你能买到的润滑油类型半合成润滑油通常是矿物润滑和全合成润滑油的混合物。在市场上,半合成润滑油通常会被叫成合成科技(Synthetic Technology)润滑油

Q:这三种类型的引擎润滑油有什么区别?

A:它们其实都是矿物提炼的润滑油,但全合成润滑油是从普通矿物润滑油精炼提纯而来的,将矿物润滑油提炼成合成润滑油的成本是很昂贵的。

尽管合成橡胶是人工合成的橡胶,但合成润滑油却不是人工合成的润滑油

Q:合成润滑油有什么优点呢?

A:首先,合成润滑油的油分子大小更加均匀,Lubrita的示意图就很好地展现了这一点。

如果你没有正经地要进行赛车运动,你就不需要对引擎润滑油如此挑剔

合成润滑油的优点还有:

  • 更好的低温/高温性能
  • 具有延长保养周期的可能性
  • 提升燃油经济性(仅针对特定的引擎配置)
  • 增加马力和扭力

只要读到增加马力提升燃油经济性,然后说服自己使用合成润滑油,这就够了。合成润滑油还有更多优点,但是如果我们要继续谈下去,你就要先想办法提高自己的知识水平了。

Q:“那我能够在Lazada上购买这款RM70的引擎润滑油吗?”

A:你自己的生活,你说了算,但是你必须要承担后果。买到假货的风险是很大的,而伪造的引擎润滑油很可能会损害你的引擎。好好对待你的车,给他用推荐级别的正品润滑油吧。

Q:怎么样才能买到正品引擎润滑油呢?

A:这个问题并不在今天的讨论范围内,不过润滑油生产商正在采取措施来遏制假货的泛滥,所以你可以从各家润滑油生产商那里了解更多的信息。

Spied: Red hot! 2023 Proton S50 (or is it S70?) seen undisguised, inches closer to launch

Our first real look at the upcoming 2023 Proton S50 - rumoured to also be named the Proton S70 - comes courtesy of this spyshot snapped by Mohd Sabri Mohd Sirah on a Facebook group. Undisguised for all to see, the pic (albeit blurry) showcases the basic look of the sedan: the front and rear bumpers, at least from the sides look the same as its donor model, the Geely Emgrand. However we do know that more differences will be on the front fascia courtesy of a studded grille, as seen in earlier spys

According to the latest sales data published by the Vietnam Automobile Manufacturers’ Association (VAMA), Vietnam’s equivalent of the Malaysian Automotive Association (MAA), the best-selling car in September 2023 is the Mazda CX-5.
