Z Premium 10W40 engine oil is a type of multi-grade motor oil designed for use in a wide range of gasoline and diesel engines. The "10W40" designation indicates its viscosity rating. HereÕs a breakdown of what each part of the label means: 10W: The "10W" part stands for the oil's viscosity at low temperatures (the "W" stands for winter). This means the oil has a certain thickness at cold temperatures, allowing it to flow more easily during cold starts compared to oils with higher "W" ratings (e.g., 15W or 20W). 40: The "40" indicates the oilÕs viscosity at high operating temperatures. A higher number means the oil will be thicker and provide better lubrication at high temperatures. Z Premium: This is likely a brand or product line name, suggesting certain qualities or additives that enhance performance, protect against wear, reduce deposits, and perhaps improve fuel economy. Key Features and Benefits Versatility: Suitable for both gasoline and diesel engines. Temperature Range: Effective across a wide range of temperatures, providing reliable lubrication in both cold starts and high-temperature conditions. Engine Protection: Often includes additives that protect against wear, reduce deposits, and keep the engine clean. Extended Oil Change Intervals: Many modern 10W40 oils are formulated to last longer, meaning fewer oil changes.
