基礎油(base oil)種類分成以下5種類別:
第一類基礎油 API Group I,傳統溶劑精煉礦物油;
第二類基礎油 API Group II,加氫裂解礦物油;
第三類基礎油API Group III,高度加氫裂解或加氫異構化蠟;
第四類基礎油API Group IV,聚α-烯烴(PAO);
第五類基礎油 API Group V,其他合成油


感謝 work 大的資訊!

但從我找到的資料裡面,并沒有明確說明是哪一類的基礎油。
只看到是 W-Base 這個定義而已,看起來已經不屬於上述的定義範圍之內了。
上面找來您說看不懂的資料,丟給 google 直接翻譯如下:

WBASE (Better Cold Flow Base Oil) :
WBASE(更好的低溫流動性基礎油):

SUSTINA is made with WBASE, the newest base oil technology from Nippon Oil.
SUSTINA是用WBASE,最新的技術從基礎油新日本石油。
Typical synthetic base oil is made up of carbon and hydrogen ring shaped molecular structures.
典型的合成基礎油是由碳和氫的環狀分子結構。
As these structures move, they tend to collide and intertwine, slowing their movement especially at cold temperatures, resulting in very high cold start viscosity.
由於這些結構的舉動,他們往往碰撞和交織,減緩他們的運動,特別是在寒冷的氣溫,造成非常高的冷啟動的黏度。
WBASE technology realigns the carbon and hydrogen structure into straight lines, allowing free movement of the molecules even at low temperatures, providing lower engine drag and improved fuel efficiency.
WBASE技術重新調整結構的碳和氫成直線,允許自由流動的分子,即使在低溫條件下,提供較低的發動機阻力,提高燃油效率。

按大大所列的“第五類基礎油 API Group V,其他合成油”來定義,
又裡面提到跟“典型的合成基礎油”的比較,看來也不屬於 Group V 才對。

應該不是,第三類的機油不能冠以 Fully Synthetic 這樣的標識在其產品上。
如果是第三類混搭合成油,也只能寫 Synthetic Blend 。

前者是全合成機油,後者是半合成機油

Semi-synthetic oil
Semi-synthetic oils (also called 'synthetic blends') are blends of mineral oil with no more than 30% synthetic oil. Designed to have many of the benefits of synthetic oil without matching the cost of pure synthetic oil. Motul introduced the first semi-synthetic motor oil in 1966.[14]

Lubricants which have synthetic base stocks even lower 30%, high performance additive packs consisting of esters can also be considered as synthetic lubricants. Ratio of the synthetic base stock is generally used to define commodity codes among the customs declarations of tax purposes.

How does WBase compare to PAO? Like PAO, WBase is a high-performance synthetic base oil. In comparison, though, WBase has a higher Viscosity Index (VI) – when considering 4cSt base stocks, PAO has a VI of 124, while WBase has a VI of 140. This translates to higher stability across broader viscosity ranges, while requiring smaller amounts of VI Improver.

小弟認為不需要一直陷在要將這罐油做 Group XXX 的分類。
它的 WBase 的 Viscosity Index 4cSt 不會比 Group IV PAO 來得差。甚至來得好。
它的 ZP anti-wear 成份不含 sulfur ,光這點就差很多了。

Once all of the detergents are destroyed by the acids, the oil can no longer perform one of its primary functions – keeping dirt and contaminants in suspension. The industry-wide response to this is to have a high TBN in order to neutralize the acids, but this is only effective to a point.

以上解釋已經夠清楚了,它的清潔性會更好。

以上,有錯請指正。

How does WBase compare to PAO? Like PAO, WBase is a high-performance synthetic base oil. In comparison, though, WBase has a higher Viscosity Index (VI) – when considering 4cSt base stocks, PAO has a VI of 124, while WBase has a VI of 140. This translates to higher stability across broader viscosity ranges, while requiring smaller amounts of VI Improver.

小弟認為不需要一直陷在要將這罐油做 Group XXX 的分類。
它的 WBase 的 Viscosity Index 4cSt 不會比 Group IV PAO 來得差。甚至來得好。
它的 ZP anti-wear 成份不含 sulfur ,光這點就差很多了。

Once all of the detergents are destroyed by the acids, the oil can no longer perform one of its primary functions – keeping dirt and contaminants in suspension. The industry-wide response to this is to have a high TBN in order to neutralize the acids, but this is only effective to a point.

以上解釋已經夠清楚了,它的清潔性會更好。
以上,有錯請指正。

上面實在看不懂
低溫的動黏度指數不是低一點比較好?
4度C的動黏度指數怎麼會140比124好?


這小弟也沒法子解釋,有請高人指點。😆

但是: 整句

小弟認為這才是它想強調的重點。


我覺得要強調的重點是這句
while requiring smaller amounts of VI Improver.
可以減少使用VI Improver


都OK啦!🙂

反正大家互相討論,都會學到一點東西。
