我最近測試完,我想用這款:
看完網站上的 white papers 介紹,我真的覺得是一款很強的齒輪油,同時看網友詢問美國製造商,耐用度也不是問題, 也不太會腐蝕 銅的零件,與油封,但有銅零件的話還是小評估
這款油是紅色的,而且味道跟一般齒輪油很不同,沒有明顯的臭味,是很特殊的配方

HEAVY SHOCKPROOF®
Film thickness greater than an SAE 75W250, yet low fluid friction like 75W90
For heavily-loaded racing differentials and transmissions, problem gearboxes
Many performance racing applications like Sprint/Midget/Dirt Late Model Differentials, Detroit Lockers and spools, NHRA Top Fuel and Funny Car rear ends
Not recommended for most synchro applications due to the product's extreme slipperiness
選擇的話,我是依據認證為主:
1. 濃度要符合原廠建議值
2. API GL-4, 或是 GL-5, GL-4 比較適合用於有銅零件的齒輪箱
3. SAE J2360 這個認正確保不會腐蝕油封
HEAVY SHOCKPROOF 的認證沒這麼多項,但我有問美國 red line 與參考網友詢問 red line 的回覆, 應該也都符合上述要求
