你不參考。我跟娜大比較不懂 所以還是把他拿來參考用。而不是唯一根據.....
What is the HTHS value for engine oil?
HTHS is the abbreviation for “High Temperature High Share”. It is the apparent viscosity of a multigrade engine oil at 150 °C (high temperature in the engine compartment) and a velocity gradient of 106*s-1 in a defined measuring vessel according to the method CEC-L-36-A-97. The measurement is carried out in a rotational viscometer. The HTHS value provides information about the fuel efficiency properties of an engine oil and the potential fuel savings that can be achieved with the oil.
HTHS viscosity
The HTHS value is a measure of the viscosity of an engine oil under demanding conditions. Defined limit values ensure that even with high-performance engines, the engine oils can maintain a tear-resistant lubricating film in the bearing area at high temperatures and high speeds (shear stability). The unit for measuring HTHS is mPas (millipascal second). If the HTHS value is above 3.5 mPas, the HTHS viscosity is to be classified as normal. An HTHS value below 3.5 mPas is referred to as a reduced HTHS viscosity. Engine oils with reduced HTHS viscosity were developed for special engines. You should therefore only fill it in if your vehicle has been approved for this by the OEM. The HTHS viscosity of engine oils is important for the ACEA classification. - Classes A1, A5 and B1, B5 require an HTHS value of 2.9 to max. 3.5 mPas (reduced HTHS viscosity).
- The classes A2, A3, B2, B3 as well as E2, E3, E4 and E5 require an HTHS value of over 3.5 mPas (normal HTHS viscosity).
- For classes C1 and C2, HTHS values ≥ 2.9 are required.
Class C5 includes HTHS values from ≥ 2.6 to ≤ 2.9 mPas and can only be implemented for SAE classes 0w20 and 5w20.
德國龍資深一點都聽過吧?!不是什麼兩光潤滑油廠。
機油的HTHS值是多少？
HTHS是“高溫高份額”的縮寫。它是一種的表觀粘度 多級發動機油在150℃（在發動機艙的高溫）和為10的速度梯度6 * S -1在限定的測量容器根據該方法CEC-L-36-A- 97。該測量在旋轉粘度計中進行。HTHS值提供有關發動機機油的 燃油效率特性以及該機油可以實現的潛在節油信息。
HTHS粘度
HTHS值是在苛刻條件下機油粘度的量度。定義的極限值可確保即使在使用高性能發動機的情況下，發動機油也可以在高溫和高速下在軸承區域內保持抗撕裂的潤滑膜（剪切穩定性）。 HTHS的測量單位是mPas（毫帕秒）。如果HTHS值高於3.5 mPas，則將HTHS粘度歸為正常。低於3.5 mPas的HTHS值稱為降低的HTHS粘度。 HTHS粘度降低的機油是為特殊發動機開發的。因此，只有在您的車輛已獲得OEM批准的情況下，才應填寫。機油的HTHS粘度對於ACEA分類很重要。 - A1，A5和B1，B5類要求HTHS值為2.9到最大值。3.5 mPas（降低的HTHS粘度）。
- A2，A3，B2，B3以及E2，E3，E4和E5類要求HTHS值超過3.5 mPas（正常HTHS粘度）。
- 對於C1和C2類，要求HTHS值≥2.9。
C5類的HTHS值範圍從≥2.6到≤2.9 mPas，並且只能用於SAE 0w20和5w20類。
Google 翻譯的比較不順。
就好像我跟娜大說。糟糕我的機油 都改成PAO 比例比較高的機油在使用 第三類基礎油。慢慢的減少。中了PAO的毒了
