Difference between 5w-30 and 10w-40? - All Questions About Your Vehicle

Viscosity is a term that indicates the resistance of oils to fluency. All engine oils are classified with the SAE serial number. The SAE nickname refers to the initials of the Association of Motor Vehicle Engineers (Society of Automotive Enginers) in the United States. The SAE standard of engine oils is regulated by this union. Oils with a smaller SAE number become thinner and more fluid. Oils with large SAE numbers become thicker and less runny. For example, oil numbered SAE 10 is thinner and runner than oil numbered SAE 30. Engine oils are manufactured in separate features for gasoline and diesel engines. In gasoline engines; Oils starting with the letter S are used, such as SA, SB, SC, SD. In diesel engines; Oils starting with the letter C, such as CA, CB, CC, CD, are used.

b) Winter Oils: Oils such as SAE5W, SAE10W, SAE20 W. The letter W determines that the oil is winter, is the first letter of the word winter in English.

c) Combined Oils (Four Season Oils): This type of oil is used in every season. Summer oil in summer shows winter oil in winter. However, it can never replace neither summer oil nor winter oil.
