舉例而言：12cst@100℃ 約當於 3.5cp@150℃(HTHS)

翻成白話就是：如果某隻油在油溫100度時之黏度為12cst，則可用此表查出此油之HTHS大約為3.5cp，反之亦然

耐久性：

HDEO對xW-40的剪切穩定要求是12.5cst@100℃以上


MCF vs 300V

不耐久的例子：

下圖這隻使用過的10W40，其黏度只剩10.35cst@100℃，換算成HTHS大約只有3.05，但SAE J300要求10W40的HTHS要有3.5以上

以前單純看番號，現今機油的發展，要看數據...

Мой автомобиль, 2013 года выпуска, Range Rover Sport турбо дизель 3л мощность 292 лошадиные силы, использует строго один тип моторного масла A5 5W-30.

Я решил отбирать небольшие пробы масла, через каждую тысячу километров и смотреть, что с ним происходит.

После трех тысяч километров пробега масло становится жидким как вода.

單級機油的優勢(低磨損)



The SAE paper the following graph is from has been discussed in the aviation forum before. It shows the relative cylinder wall wear vs temp for straight 10W, 10w30, and straight 30.

Keeping in mind that this is just cylinder wall wear, I was still surprised that 10W and 10w30 didn't perform better at low temps. But the real surprise is just how flat the wear curve is for SAE 30.

Maybe the oils companies do know what they are talking about when they put something like the following in the PDS for straight grades: "Valvoline SAE 30, SAE 40, and SAE 50 offer excellent protection to gasoline engines operating under high temperature and heavy-duty service(hauling trailers, boats or RVs for sustained periods).

看沒有啦 有中文嗎?!我還以為來到國外網站
