Car Engine Oil Types

The right oil change for every car

If your car needs an oil change you need to know what engine oil to use, and getting that right is all about liquid engineering. In the case of full synthetic oils, base oils are refined in a way that actually changes their molecular structure.

 

Whether you choose a mineral or synthetic oil, it's the advanced additives we create in our labs that ensure Castrol oils meet the exact specifications and ever-greater demands of vehicle manufacturers.

 

The latest European engines are incredibly powerful for their size, and so demand synthetic oils that are thin enough to protect them from the second you start them up and strong enough to withstand the incredible pressures they reach under everyday driving conditions.

 

Late model Japanese imports require low viscosity, 0W engine oils that improve fuel economy but also have the strength to stand up to 10,000 or even 15,000 mile drain intervals.

Many car manufacturers have been recommending full synthetic engine oil for years. Our Liquid Engineers work directly with car manufacturers to create engine oils that protect warranties as well as engine components.

Knowing what engine oil to use matters. Part synthetic engine oils provide a balance between the economy of mineral oil and the strength of full synthetic oil.
