Frequently Asked Questions - Full Synthetic Oil

What is synthetic oil?

Synthetic oil is a specially engineered lubricant made from chemicals instead of natural oil. It's designed to offer better engine protection and performance compared to regular oil. With its advanced formula, synthetic oil lasts longer, resists heat better, and helps engines run smoother and longer.

What kind of synthetic oil should I use?

The type of synthetic oil you should use depends on your vehicle's requirements, outlined in the owner's manual. Factors such as engine type, driving conditions, and climate influence the choice between full synthetic or synthetic blends. Full synthetic oils offer superior performance and protection, while synthetic blends provide a balance of performance and affordability.

Unsure which full synthetic oil is suitable for your car? Simply enter your car's registration into the 'My Garage' tool on our website to find which synthetic oils are compatible for your specific vehicle make and model. Additionally, check out our handy DIY guide if you want to learn more about the signs when your vehicle requires an oil change.

What is the difference between 5W-30 oil and 5W-40 oil?

The main difference between 5W-30 and 5W-40 oil lies in the viscosity ratings, indicating how the oil behaves at different temperatures. Both oils have the same cold temperature viscosity (5W), but 5W-40 oil has a slightly higher viscosity at operating temperatures compared to 5W-30 oil.
