Synthetic Oils Vs Mineral Oils

One of the most common questions surrounding engine oils is the debate between synthetic and mineral oils - which is better?

Difference between Synethetic oils and mineral oils

Both types of oil are derived from the same base crude oils, but synthetic oil is further refined so that it can be tailored to meet different specifications. The extra processes also mean that the synthetic oil is of a better quality than mineral oil as the refining procedures help to remove any impurities.

Synthetic oils offer better protection for engines due to their lower viscosity and high temperature stability. This is because they have been developed to cope with the extreme conditions found in modern engines.

Due to its improved qualities, synthetic oil is able to flow through the engine more freely, even when cold. Mineral oils take longer to circulate around an engine, which means that when the engine is first started friction occurs between unlubricated parts, potentially causing damage and premature wear.

Because synthetic oils flow more quickly through an engine they are able to significantly improve the fuel economy of an engine. Synthetic oils can flow whilst the engine is still cold, which in turn eases the burden on the engine when it is first started.

Synthetic oils are also more environmentally friendly and help engines to cut emissions. They contain less harmful impurities such as sulphur and reactive hydrocarbons which are detrimental to the environment.

When purchasing oil for your engine, always refer to the manufacturers manual for the correct grade and viscosity.
