What is the correct engine oil for Subaru Outback? You need to use oil that is the recommended viscosity. This is the ‘thickness’ of the oil and is usually displayed prominently on the packaging. A high viscosity oil will be more treacle-like in consistency, whereas a low viscosity oil is thinner and more free-flowing. Different engines require different engine oils. In this article you will find guidelines for the United States and Canada.
