Castrol MAGNATEC STOP-START combines DUALOCK molecules with our most efficient fully synthetic base oils, to dramatically reduce engine wear by 50%* and improve fuel economy.
There are more people living in cities than ever before, with busy driving becoming an increasing feature of everyday life. Congestion has increased dramatically over the past 10 years, causing engine wear and wasting fuel. To respond to this changing environment, Castrol MAGNATEC STOP-START with DUALOCK technology has been engineered to provide non-stop protection and improved fuel economy from every start. Even for vehicles with the latest stop-start engine technology.
0W-20 motor oil is liquid engineered to flow as easily as a 0 Weight oil in winter temperatures, yet behave like 20 Weight oil once the engine has achieved its full operating temperature. This ensures that even in cold climates, oil will start to flow through engine oil ways immediately, providing lubrication to critical engine parts.
It's a common misconception that the 'W' in viscosity descriptions stands for Weight. In fact, it stands for Winter. In the case of synthetic 0W-20 oil, this means that it flows as easily as a 0 Weight oil in Winter temperatures, but is as thick and viscous as a 20 Weight oil once normal engine temperature has been reached.
