請問大家自備機油都自(恕刪)
有空可以看看這位老兄實際測試各廠牌機油其磨損保護能力,不見得貴的就是好。
若要自備,建議還是依照原廠保養使用番號,去找相對應保護高的機油做更換。

有各廠牌機油抗剪力的真實實驗數據。
And we’ve seen that for many years with factory filled synthetic 5W30 Mobil 1 (which is one of the top ranked oils regarding wear protection capability) in countless thousands of brand new vehicles, that always break-in their components and seal their rings just fine. That means so-called break-in oils are completely unnecessary. And the poor wear protection provided by most break-in oils, can put a flat tappet engine in serious danger of wiping lobes. No matter what anyone tells you, for roller lifter engines or for flat tappet engines (no matter how wicked they may be), it is best to use a highly ranked oil, no matter how much zinc is in it, for BOTH break-in and after break-in. In fact, the SAME highly ranked oil can be used for both purposes, meaning you can choose a single highly ranked oil and stay with it from first fire, on.
多年來,我們已經看到,在無數全新車輛中使用工廠填充的合成 5W30 美孚 1 號(在磨損保護能力方面排名最高的油之一),它們總是磨合它們的組件並密封它們的環美好的。這意味著完全不需要所謂的磨合油。大多數磨合機油提供的磨損保護較差,會使扁平挺桿發動機面臨刮油葉的嚴重危險。無論任何人告訴你什麼,對於滾柱式發動機或平挺桿發動機(無論它們多麼邪惡),最好使用排名靠前的機油,無論其中含有多少鋅,都可以磨合和闖入後。
磨損保護參考類別是:
* 超過 150,000 psi = 壯觀的磨損保護
* 135,000 psi 至 150,000 psi = 驚人的磨損保護
* 120,000 psi 至 135,000 psi = 出色的磨損保護
* 105,000 至 120,000 psi = 令人難以置信的磨損保護
* 90,000 至 105,000 psi = 出色的磨損保護
* 75,000 至 90,000 psi = 良好的磨損保護
* 60,000 至 75,000 psi = 中等磨損保護
* 50,000 至 60,000 psi = 不理想的低磨損保護
* 低於 50,000 psi = 注意 – 磨損保護極低
psi值越高,磨損保護越好。
