非常詭異的標示,是不是標示錯誤呢?我想在台灣也沒有人會在乎這種細節部分.
參考一下這一頁:

ACEA C3 oils are Top Tier lower SAPS1 lubricants. They are designed for use in high performance gasoline and light duty diesel engines where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) and Three Way Catalysts (TWC) are used. ACEA C3 oils are typically SAE 5W-30 or SAE 5W-40 based on API Group III base oils.
重點是這一段
ACEA C3 oils are typically SAE 5W-30 or SAE 5W-40 based on API Group III base oils.
幾乎所有的C3機油都是用HE加氫鍵練解基礎油,而不是Group IV的人工合成基礎油.
所以市面上符合VW507的油品幾乎都看不到"全合成"這三個字,因為多少有添加HE加氫鍵練解基礎油,主要原因是為了長效.
全合成基礎油容易變酸,清潔能力沒有石油基來的好,目前尚無法符合長效的功能.
再來
我不知道3M是否有自己的煉油廠
看包裝就很有
ESSO的味道
應該是OEM賣牌子的吧
