Synthetic vs conventional engine oil
Why should you choose full synthetic engine oil?
Most modern cars will already use a full synthetic engine oil, however older cars can still benefit from using a full synthetic oil.*
Full synthetic oils offer your engine the best possible performance and delivering optimum protection from the moment you start the engine. They work harder in all scenarios that put stress on an engine, such as driving in extreme temperatures, towing heavy loads and sitting in stop-start traffic.
Depending on the viscosity your manual recommends, synthetic oil can also improve the performance and fuel economy of your vehicle, and will even stay stronger for longer between drain intervals than traditional mineral or part synthetic oils.
