The term “5w 20 oil” refers to the viscosity and weight of a specific type of motor oil. The “5w” indicates the oil’s viscosity at low temperatures, while the “20” indicates its viscosity at high temperatures. The “w” stands for “winter,” and a lower number indicates that the oil will flow more easily at low temperatures. “Synthetic” oil is a type of motor oil that is made from chemically engineered compounds, rather than from refined crude oil. Synthetic oils offer a number of advantages over conventional oils, including better protection against wear and tear, improved fuel economy, and longer oil change intervals.
Whether or not 5w 20 oil is synthetic depends on the specific brand and product. Some brands of 5w 20 oil are synthetic, while others are conventional. It is important to check the product label to determine whether or not a specific 5w 20 oil is synthetic.
