Gear Oil and Motor Oil Are Not the Same
Gear oil differs from motor oil. Most people assume that SAE 90 gear oil is much thicker than SAE 40 or 50 grade motor oil. However, they are the same viscosity. The difference is they are calculated by different classifications, SAE gear lube and SAE engine oil. Another main difference is the additives used to produce them.
基本上黏度沒甚麼差 但是添加劑跟製造方式有差
Engine oils and gear oils both have anti-wear additives, and they both must lubricate, cool and protect components, but gear oils are placed under extreme amounts of pressure, creating a propensity for boundary lubrication, a condition in which a full fluid lubricating film is not present between two rubbing surfaces. For example, differentials in cars and trucks have a ring and pinion hypoid gear set. A hypoid gear set can experience boundary lubrication, pressures and sliding action that can wipe most of the lubricant off the gears. To combat this extreme environment, extreme pressure additives are incorporated into the oil. use an extra treatment of extreme pressure additives in its gear oils in order to reduce wear and extend the gear and bearing life.

所以工作環境跟添加劑是有所差別的
油膜不破裂靠得反而是添加劑而不是黏度 消泡性也比機油更重要了
以台灣速克達的環境來說 其實零件也相對便宜 所以說沒延長機件壽命坦白說也不痛不養
更或者是說是累計的傷害其實也不多 所以騎到很多的里程數之後 齒輪沒先掛 其他零件反而還先損毀 老化
用的是機油還是齒輪油就沒那麼重要了
個人還是用原廠的齒輪油拉 基本上價位也沒特別高 所以只求"安心"就好![[詢問]機油當齒輪油騎乘的感覺差異?2、4行程又有何不同?6979](static/image/smiley/jorsindo/em40.gif)
