Why synthetic oils

What are synthetic oils and what do they do?

Your engine is a complex machine with hundreds of moving parts that operate under a wide range of temperatures and stressors. The oil you select needs to be equally capable of coping with these operating conditions to protect your engine against wear, corrosion, and the build up of dirt and deposits.

Lubricants heavily influence: Performance, Fuel consumption, Emissions
Lubricants are responsible for: Wear protection, Engine cleanliness, Long engine life


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.

To understand synthetic engine oils, let's look at the origins of engine oils.

There are two basic types of lubricants available:
1. Conventional mineral oils are the traditional types.
2. Synthetic lubricants which are growing in popularity.

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.

Synthetic oils can also significantly improve fuel economy. 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.

Another advantage of synthetics is that they're cleaner and environmentally-friendlier - 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 oil, Mobil 1 offers significant advantages over conventional engine oils, such as:

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