What does 5W20 mean?
In 5W20, for example, the “W” stands for “wwinter,” while the “5” is the classification of the oil. This lets you know well the oil will fare in colder temperatures. The larger number, in this case, 20, refers to how well the oil performs in hot temperatures. You can tell the thickness of oil at any given temperature by examining these numbers.
What is a 5W oil rating?
An oil rating, such as 5W-20 and 5W-30, indicates the viscosity of the motor oil. The viscosity rating is determined by the resistance to flow the oil exhibits under a given temperature. Higher viscosity ratings indicate a thicker oil, which therefore flows less easily.
Will thicker oil make engine hotter?
Definitely! Oil viscosity is measured in resistance to flow. The thicker it is, the more resistance and more heat generated.
Does oil get thicker as it heats up?
That first number, with the “W” (which stands for “winter” not “weight”) is the “cold” viscosity, and the second number is the “hot” viscosity “No, that doesn’t mean the oil gets thicker as it heats up. It means that it behaves like a thicker oil, at higher temperatures,” says Fenske.
Should I use thicker or thinner engine oil?
Bottom line on using thicker oil or thinner oil Using a viscosity one grade higher or lower than what’s recommended for your engine likely won’t do lasting harm. But, to alleviate any concerns about engine protection and your vehicle warranty, it’s best to use the viscosity recommended in your owner’s manual.
Why is my engine oil thicker in the morning?
The oil inside your engine cools as it sits overnight. As it cools, its viscosity increases (it thickens). When it’s time to start your vehicle in the morning, the thicker oil doesn’t flow through the engine as readily as it does when it’s at operating temperature.
What happens if you use oil with a low viscosity?
Just like using an oil with too high a viscosity may lead to problems in Josh’s engine, using an oil with too low a viscosity can have the same result. Oil that’s too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.

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.
Does 10W30 oil work in cold weather?
That said, the somewhat thinner 10W30 oilwill perform better in colder climates. In cold weather, engine oil only deals with engine heat as the cold temperature of the environment won’t add thermal stress. A low viscosity oil will move quicker through the engine to keep it lubricated and cool.
Why do modern cars use thinner oil?
Thinner oils have less drag, and therefore less friction and wear.
What happens if your engine oil is too thin?
The reason for this is the hotter the oil gets the thinner it gets. If the oil gets too thin then it starts affecting your oil pressure. The engine oil pump has a pressure relief valve in it that helps to a certain point. The pump delivers more oil than the engine need and dumps the rest via the relief valve.
What does lower viscosity mean for engine oil?
The lower this number is, the thinner the engine oil (see the video above). The trend towards lower viscosities calls for new engine oil formulations to cover the latest OEM specifications. The lower the viscosity of an engine oil, the more important the chemical protection of the engine becomes.
Why should you use synthetic engine oil?

Is thicker oil better for older engines?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.
Is thicker oil better?
And sometimes as engines add more miles, a little thicker oil works wonders. Well, in went 0W-40. Maybe it’s just me, but my engine seems to like it. Smooth, maybe even more power. Hard to believe. I feel I’m getting just as good mileage or better with this thicker oil. So since there is no warranty to worry about, is this acceptable?
Should I use thicker oil for old Pistons?
Using thicker oil for old pistons might not be a good idea. When a car gets old, it starts consuming more engine oil compared to the new ones, and when you add thicker oil to that engine, the situation gets even worse. That said, not all thicker oils are bad for weary engines.
Why is engine oil thinner than recommended?
Because the thinner the oil, the easier it is for the oil to enter into narrow gaps. So that this can cause the oil to burn in the combustion chamber. Therefore some mechanics recommend using engine oil that is one level thicker than the recommended engine oil for engines that are considered old.
Is it possible to increase oil pressure in an older engine?
Yes, because it is a feasible method to improve oil pressure in an older engine. Slightly more viscous oil will help you in protect worn bearings too. When heavier oil will be added to the engine, it will never leak and throw extra smoke out of the engine. Thicker oil can be the best motor oil for hot weather.
Is it OK to use 10w30 instead of 5W-30?
You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperatures. Generally, the viscosity difference between the two is neglectable. However, it’s important to note that a 10w30 oil will move slower than a 5w30 oil in cold environments.
Is 5W-30 oil better than 10W-30?
The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30. In fact, some automakers allow you to switch to a lower viscosity oil depending on weather. Find the Right Viscosity Oil for Your Engine
Should I use 20w50 oil on my engine?
It’s important to note, that your engine’s oil pump, and thus the engine, has to work extremely hard to pump thicker oil and maintain oil pressure, so folks that would resort to 20w50 oil on their tired, old engine would also sacrifice horsepower using it.
