Choosing the Right Engine Oil

When choosing a motor oil for your car, the most important thing is the viscosity and the easiest way to pick the best engine oils for your car is to consult the owner's manual. Different engines require different viscosity engine oil to protect and operate correctly, depending on the manufacturer specifications. In simple terms, viscosity just means thickness. A low viscosity or light weight engine oil will appear smooth and flowing like water, however a higher viscosity or heavier oil will appear thicker, similar to honey or maple syrup.

What Is the Difference Between a Mineral Engine Oil and Synthetic Engine Oil?

Designed to suit a range of engine types, applications, driving styles and budgets, one of the main variations between oils are whether they are a fully synthetic, semi-synthetic, or mineral based engine oil.

• Mineral oils use more base oils and suit every-day use and are usually the right oil for older vehicles. However, for higher levels of protection and cleaning under intense driving conditions, semi-synthetic and full synthetic engine oils can be a better option.
• Semi-synthetic engine oils are a great middle ground, featuring some of the best bits of the full synthetic option whilst offering a well-performing lubrication solution that is friendly to your wallet. These engine oils work by offering better resistance to friction on metal surfaces in both low and high operating temperatures when compared to a mineral engine oil.
• Full synthetic engine oil will undergo an extensive lab treatment to provide a mixture of chemical additives and oil that make them perform significantly better than their mineral base oil counterparts. Apart from better extreme temperature performance, synthetic engine oils are formulated to provide low sludge and less corrosion formation as well as containing better detergents when you compare with mineral and synthetic oils. They also provide greater fuel economy based on their low viscosity. Keep in mind that the refining process is expensive and lengthy typically making synthetic engine oils the most expensive on the market.
