最近车子换档很不顺，花了些时间了解变速箱油，下面说说我了解的
其实，Mobil LS 75W90的介绍里清楚的标明含有硫磷添加剂（sulfur-phosphorous additive ），有没有腐蚀自己去想了。
Mobil 1 Synthetic Gear Lubricant LS 75W-90 combines wax-free synthesized hydrocarbon base oils and a specially designed extreme-pressure, limited-slip, sulfur-phosphorous additive system to provide a significantly higher level of performance in rear axles and differentials versus conventional fluids.
另外mobil 网站有位老兄想把GL5的 75W90油用在自己的丰田Echo（我们的夏利2000？）上，但担心腐蚀，Mobil的官方回答是不合适用GL5。下面有链接，有兴趣可以看下。别的品牌的GL5有没有腐蚀，没研究过，不敢说。
answer:
Mobil 1 Synthetic Gear Oil is recommended for all applications where a GL-5 lubricant is specified. GL-5 type lubricants, which have a higher level of additive **stry, can be corrosive to yellow metals such as copper, brass, etc., and in these applications a GL-4 product is usually specified.
