What are Synthetic Oils?

A synthetic lubricant contains more highly refined base oils than those used in conventional mineral oils, offering you superior protection and performance. Synthetic engine oils provide a variety of benefits that keep your engine running at optimal performance for years.

Types of Engine Oil

There are two basic types of engine oil available:

  1. Conventional mineral oils are the traditional types of engine oil and are still most widely used.
  2. Synthetic motor oils which are steadily growing in popularity.

There are also semi-synthetic oils, which are a blend of synthetic oils and conventional mineral oils. Semi-synthetic oils are also sometimes called "blends".

Both types of engine oil are made from crude oil that comes from the ground. The difference is that synthetic motor oils are made from more advanced refining processes and are of a higher purity and quality than conventional mineral oils or semi-synthetic oils. This not only removes more impurities from the crude oil, it enables individual molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance, even in extreme conditions.

What's so good about 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 is 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 faster, reducing friction, and protecting moving parts within the engine.

Synthetic motor oils can also significantly improve fuel economy and reduce oil consumption. During the warm-up period of a typical car journey, mineral oils are thicker and move slower, making the engine thirstier and less efficient. Because synthetics get to work much quicker, the engine reaches peak operating efficiency that much sooner and reduces oil consumption.

Another advantage of synthetics in the synthetic oils vs mineral oils debate is that they're cleaner and more environmentally friendly - helping to cut engine emissions when compared to conventional mineral oils. Conventional mineral oils also contain greater amounts of impurities, such as sulfur, reactive and unstable hydrocarbons and other undesirable contaminants that cannot be completely removed by conventional refining of crude oil.

In all these important respects, synthetic lubricants easily outperform mineral oils. As a 100% synthetic motor oil, Mobil 1 offers significant advantages over conventional engine oils, such as:

  • Outstanding protection
  • Minimizing oil degradation
  • Faster lubrication at start-up in low temperatures
  • Excellent protection at high temperatures
  • Exceptional resistance to thermal breakdown
  • Engine cleanliness
  • Outstanding protection against harmful deposits
  • Cleaner running engines
  • Engine efficiency
  • Greater resistance to oil oxidation (thickening), which reduces engine drag
  • Lower oil consumption under high-speed conditions
  • More efficient engine operation over a wider temperature range
  • Reduces friction and protects moving parts within the engine
  • Prevents rust
