The first number precedes the letter ‘W’ which stands for Winter. This measurement is related to how an oil flows when it is cold, such as at engine start-up. The second number is defined by how an oil flows at normal engine operating temperatures.
What does W mean in lubricant?
The “w” stands for winter and indicates that the lubricant in question has a different viscosity, or different flow characteristics, based on temperature. For example, a 5w30 oil weight rating means that on cold start-up — even at subzero temperatures — the oil flows like a 5 weight oil.
What is 5W-30 motor oil?
5W-30 motor oil is a type of oil that is used in many modern vehicles. The “W” stands for winter, and the “30” stands for the oil’s viscosity, or how thick it is. Viscosity is measured at two different temperatures, cold and hot. The first number, 5 in this case, corresponds to the oil’s viscosity at cold temperatures.
What does the number in engine oil mean?
The numbers in oil signify the oil’s viscosity or thickness. The lower the number, the thinner the oil and the easier it flows. The higher the number, the thicker the oil and the slower it flows. All oils have a certain degree of viscosity, which is affected by temperature. When it’s cold outside, your motor oil thickens and doesn’t flow as easily.
What is oil weight?
Oil weight is a term used to describe the viscosity of an oil, which means how well it flows at a specific temperature. The Society of Automotive Engineers (SAE) assigns a viscosity number, or weight, to oil based on its flow at 210 degrees F, which is roughly the standard operating temperature for most motors.
Can I use 10w40 instead of 5W-30?
A common question is whether it’s safe to use 10W-30 instead of 5W-30 oil, for example. While it’s best to use what’s recommended in your owner’s manual, inadvertently using a viscosity one grade higher or lower than what’s recommended generally poses no long-term harm.
What is the difference between 10W-40 and 5W-30 motor oil?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil. The second number in the motor oil’s name describes the viscosity of the oil when the engine is warm and the oil reaches operating temperature.
Can I run all 10W40?
Heck you can run all 10w40 if you like. You migth lose a little gas milage but that is all. No one quart will not do any “damage”. Heck you can run all 10w40 if you like. You migth lose a little gas milage but that is all. Thanks. I did seem to notice that. It felt a little… “sticky” and the gas light was on before we got it home.
What kind of oil should I use for my engine?
If your engine needs 10w30 motor oil, you can try 15w30 motor oil if the temperature is warm. You can go with 5w30 motor oil if the weather is cold. If the temperature is freezing, then you can 0w40 motor oil. But the bottom line is that you should always use the recommended motor oil for your engine.
Is the 5W30 bad in mileage?

Which engine oil is best for my car?
Thin, low viscosity oils give better protection to engine parts at cold temperature. Thick, high viscosity oils are typically better at maintaining film strength to protect engines at high temperatures. WHICH ENGINE OIL SPECIFICATION IS RIGHT FOR YOUR CAR?
What does a 5W oil number mean?
That value has the letter “W” after the number and has a dash after the W. For example, if the oil is a 5W-30, the 5W part describes the viscosity of the oil at low temperatures. The lower the number, the faster the oil will flow at vehicle start up.
What does 10W 30 in W mean?
That’s why you see two numbers on most oils. 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 is a 10W oil?
The W stands for winter, and the 10 is the viscosity of the oil tested during the winter test. The winter rating is the oil’s ability to flow in cold temperatures. The test is completed at 0°F (-17.8°C). The higher the number the harder it is for the oil to flow at this temperature. So for example a 10W oil flows easier than a 15W oil.
What is the difference between 5W-30 and 10W-30?
When looking at 5W-30 vs 10W-30, they both provide the same viscosity at operating temperature, as indicated by their identical “30” ratings. Oil viscosity is the measure of its resistance to flow.
What does “30” mean in engine oil?
The “30” represents the oil’s viscosity at normal engine temperatures or when your vehicle has been warmed up. An important thing to note – engine oils naturally thicken as they cool and thin as they are heated. The smaller the number, the better it will flow. For example, a 5W-30 will flow more readily than a 10W-30 at start-up temperatures.
What is 5W 40 in oil?
WHAT DOES 5W-40 MEAN? “W” stands for winter. The number before the “W” signifies the viscosity of an oil at low temperatures and the number following the “W” indicates its viscosity at normal operating temperatures when the engine is running.
What does 0W 20 mean?
Breaking down the 0W-20 code, “0” is the oil’s viscosity at startup when the engine is cold, “W” stands for its winter certification, and “20” is the viscosity at higher temperatures. Lower numbers designate thinner, lower-friction oil.
