[分享] 國外神人測試44款機油做油膜強度數據

剛好看到01友人分享，好奇心去看發現還蠻詳細的實驗

一位國外網友，自行購入專業的油膜強度測試機台，測試了44款機油，
每種機油做數次測試，並超越ASTM D 2782規範(室溫測試)，
他把所有機油加熱到110度模擬實際的引擎溫度，
幾個重要的結論:

* 最新API規範的低鋅/低磷 添加機油，不管是不是全合成，表現非常傑出，
超越傳統 高鋅/高磷 號稱競技版機油

*低價的合成油表現比預期來的要好

*號數越大，油膜強度並不會比較好


機油的好壞不只看這項，還有清潔性，耐久性，流動性等等，勿以此項測試下定論，
作者也說了，沒有不好的油，意思是都能提供足夠的保護給一般使用者，
此測試僅供參考。

感謝大大分享，希望之後會有0W40的資訊

但是5W30 Mobil 1, API SN

這個番號有好多種類耶，綠的，藍的，銀的，金的，還有鐵罐跟塑膠罐.... 每種的取向都不一樣，好複雜！

5W30 Mobil 1
沒其他名稱就是銀瓶

自家主打長效耐久型的 5W30 Mobil 1 Extended Performance 15,000 mile, API SN = 83,263 psi

居然輸給主打省油的
13. 0W20 Mobil 1 Advanced Fuel Economy, API SN = 96,364 psi
以及一般銀瓶
22. 5W20 Mobil 1, API SN = 94,663 psi
看來省油的這瓶得更可以安心用了@@

5w20 Mobil 1這瓶我是在好市多購入，
用在國產300水冷羊已經2000公里，
長途不熱衰，震動也比控制的很好，
表現實在不俗。

沒半罐我用過的
10w60 10w50 5w40這些番數的沒半罐
重點是都是fuchs eni沒有
castrol有，但也沒我用過的那種

你的疑問跟我差不多

15W50 Mobil 1 崩潰

看起來加十多表現很平均，買哪支都不會特別差。

你的疑問跟我差不多

而且Extended Performance
是最貴的@@
