There are two main criteria to pay attention to when it comes to selecting motor oil: Viscosity (often referred to as weight) Synthetic vs non-synthetic First of all, if you’re under warranty, always follow the terms of the warranty, which may specify the type of oil to use. Second, even if you’re not under warranty, you should follow any recommendations your owner’s manual makes in regards to oil. Some cars require either conventional or synthetic, and this will be specified if that’s the case. However, with things like viscosity, there are sometimes reasons to deviate a little, and we’ll explain why below. Why is viscosity important? Viscosity, as you probably remember from science class, refers to the thickness of liquid matter. When it come to motor oil, the viscosity is expressed in two numbers, such as 5W-20 or 10W-30. Lower numbers mean a lower viscosity; in other words, the substance will be “thinner”. Think of high oil viscosity ... read more
