What's so good about Mobil 1 synthetic lubricants?
The performance of synthetic oils, and in particular Mobil 1, is more robust, especially in terms of low temperature pumpability and high temperature stability and protection against deposits. These attributes translate directly into less engine wear, increased fuel economy and longer engine life.
Synthetic oils have been developed specifically to cope with extreme conditions found within modern engines. They are much more free-flowing than traditional mineral oils. The biggest benefit greatly increases engine protection. When an engine is first started, a mineral oil takes some time to circulate, allowing friction between un-lubricated parts to cause wear. In contrast, a synthetic lubricant starts circulating straight away, protecting every moving part within the engine.
