5W-30 motor oil

Motor oil with viscosity 5W-30

Engine oil with a viscosity of 5W-30 is a common lubricant used in many modern vehicles. The viscosity of an engine oil indicates how fluid the oil is at different temperatures. The first number, ‘5W’, stands for the fluidity of the oil at low temperatures, where ‘W’ stands for winter. A low value such as 5W means that the oil remains fluid at cold temperatures and circulates quickly through the engine, which is particularly important during cold starts as it minimises wear.

The second number, ‘30’, indicates the viscosity of the oil at operating temperature. This number indicates that the oil remains sufficiently thick at high temperatures to protect the engine from wear, but also thin enough to maximise efficiency. 5W-30 engine oil is versatile and suitable for a wide range of vehicles, including cars, light commercial vehicles and SUVs. It offers a good balance between protection and efficiency, making it a popular choice with many car manufacturers.

Manufacturers such as Ford, BMW, Mercedes-Benz and Volkswagen often recommend 5W-30 for their vehicles as it offers excellent performance in both cold and warm climates. This oil is ideal for everyday use as it protects the engine during both short city trips and long motorway journeys, while also helping to save fuel.
