While there are many oils in the market, the best-recommended engine oil for Nissan 370Z is SAE 5W-30. However, if the prevailing temperatures are above 0вЏ (в€’18вЊ), you are better off with SAE 10W-30 or 10W-40 viscosity. The recommended oil for Nissan 350Z is the one with SAE 5W-30 viscosity. Oils with the wrong viscosity could cause severe engine damage. When choosing the right engine oil, it is important to consider the weather under which your vehicle will be operating. It changes with temperatures, where high temperature reduces thickness hence it becomes lighter and easily flows, while cold temperature thickens it, reducing the flow rate. Oil viscosity is its fluidity level determined by its thickness. Genuine Nissan engine oil or any other duly licensed equivalent should have a quality label indicating that they have gone through the necessary quality checks to avoid engine damage. All the oils used for Nissan 350Z and 370Z engines must meet these standards.Дifferent oil certification levels include API (American Petroleum Institute), ILSAC (certification or International Lubricant Standardization and Approval Committee), and SAE, which looks at the viscosity standards. Like in any other manufacturing venture, the state has the mandate to ensure that all the products released to the consumer meet the basic quality standard. Motor oils used for Nissan should meet the American Petroleum Institute (API) certification or International Lubricant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard Oils recommended for Nissan 350Z and 370Z undergo the above process and meet the desired specifications to give you the best output for your engine and value for your money.
