What is 10 W 30 engine oil?

For Example: 10W30 This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot. Low viscosities are good for cold temperatures (hence the “W” association) because the oil is thinner. Thinner motor oil flows more easily and moves quickly.

What does the W in oil weight mean?

The “w” in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil.

What does 10W mean?

In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the “W” number the better the oil’s cold temperature/cold start performance.

What does the W stand for in 5w30?

5W-30 means that this is a multigrade oil. This is indicated by the two numbers separated by a “W” 5W – shows thickness/viscosity of the oil on a start-up – when you start the car (W – stands for Winter, this indicates oil performance under colder engine temperatures when the engine has not been running)
