Nulon的Moly DTC究竟是啥？

radonradon

官网上就寥寥几个字：Nulon engine oils contain Moly DTC. This unique, state of the art, engine oil additive offers huge reductions in friction to provide improved fuel economy and provide optimum wear protection.

连DTC的全称都没给出来。

又话说Nulon这款Full Synthetic 10W-40 Hi-Tech Fast Flowing是真心不错，就比自家的Full Synthetic 5W-40 Long Life Performance便宜两三$好像。SCA前面Full Synthetic 10W-40 Hi-Tech Fast Flowing 6升装半价时入了一桶，一是从来没用过Nulon，二是夏天到了，反正是40-weight的油，尝试各种可能，三是要实在表现不行，一二百公里时就给它放掉，就当做了个flush了。但，表现可以用“惊艳”来形容。-25℃时的低温粘度只有5270cP，而嘉实多壳牌全合成的10W-40却有5700-6000cP。冷启时、升温后发动机的声儿跟5W-40相比，肉耳几乎辨别不出差别。

应该是固体润滑剂

What Does Moly DTC Do?
Moly DTC or Molybdenum Dithiocarbamate (MoDTc) is a new friction modifier technology developed for use in engine oils with multiple benefits.

Reducing friction coefficient thus reducing fuel consumption
Act as anti-wear component to reduce engine wear due to metal to metal friction
Increasing load carrying capacity
How does Moly DTC work?
Nulon Moly DTC Engine Treatment is proven to dramatically reduce the friction of contacting metal surfaces within any engine. The high tech formula actively creates a low friction sacrificial barrier immediately when metal to metal contact occurs.

Moly DTC molecules within the engine oil then continuously replenish this high strength barrier as it depletes. Reducing internal engine friction reduces metal wear, heat and allows the engine to run more efficiently giving you more power and better fuel economy.

Moly DTC has been tested and proven to provide a minimum of 28% less friction when used in engine oils without Moly DTC.

Providing additional metal to metal wear protection during cold starts, high temperatures and heavy load driving such as towing or racing, Moly DTC is the ultimate engine oil treatment for today’s modern vehicles.

这个估计就是liqui moly mos2的成分，molybdenum disulfide 二硫化钼，俗称moly

不同烷基的单硫化物和二硫化物是最早使用的极压剂，如二丁基硫化物、二辛基二硫化物、二苯基硫化物、硫化异丁烯、含硫的有机金属极压剂等。含硫的有机金属极压剂包括二丁基硫代氨基甲酸锑(铅)，二烷基二硫代氨基甲酸钼(MoTDC)等。当其受摩擦时温度升高会分解出二硫化碳(CS2)和二硫化钼(MoS2)，将金属表面的凸凹部分填平，从而起到光滑减磨作用。
另外，各种硫化油脂和硫化脂肪酸酯，由于其硫与脂肪族原材料的减磨性能相结合， 所以能够生成性能优异的极压添加剂， 四球试验机已证明其具有承受高载荷的能力。

在我看来只要原厂修理手册上没有的东西都是不太靠谱的哈

手册上……没办法包含所有东西啊。行业标准就是规定产品的指标，以此来保护终端用户的。回到机油，抗磨剂、极压剂都是不可或缺的，只是有的厂商用这个盐，有的用那个盐。

兄弟言之有理，但我觉得这个moly有点没意义，而且可能还有伤害个人感觉

看了下，跟嘉实多的magnatec的意图有点像——熄火后机油回流，但会留一层附着在金属的表面
