Why Choose a Synthetic Oil?

Synthetic lubricants are engineered to do the job of a conventional lubricant - but they do it much, much better. Think of them as bionic lubricants! Though a bit more costly to produce and, therefore, more expensive to buy, these "super lubricants" can actually save you money in the long run.

The primary function of motor oil is to provide lubrication between moving metal parts in the engine. The friction caused by these parts when they move together creates high levels of heat that cause damage unless a lubricant is introduced to the mechanism. A lubricant will smooth the surfaces and enable the parts to move freely against one another with reduced friction and, consequently, reduced wear and heat. This is a function that conventional motor oil can perform quite well but a synthetic can perform far better.

Synthetic lubricants are manufactured specifically to stand up to the severe conditions under which conventional oils might falter. They are designed to possess viscosity characteristics superior to those of mineral oils. The resulting lubricants have a molecular structure that is tailored to meet and often exceed manufacturers' criteria for high-performance engines.

Advantages of choosing a synthetic motor oil:

1. High Temperature Stability

Synthetic oils are designed to possess viscosity characteristics superior to those of mineral oils. They are able to withstand higher operating temperatures under which mineral oils begin to break down. Synthetic oils provide optimum lubrication at extreme temperatures reducing wear and extending engine life.

2. Better Lubrication on Cold Starts

Most engine wear occurs in the first 10 minutes of start-up. Synthetic oils remain fluid at these colder temperatures, flowing more readily around the engine. Mineral oils on the other hand, tend to thicken in colder temperatures.

3. Better Everyday Protection

Synthetic oils are more resistant to the chemical degradation that comes with everyday driving. Synthetic oils provide better protection for your engine under normal as well as arduous driving conditions.

For the highest level of protection, synthetic oils like those in the Castrol EDGE range come out on top every time.
