Is 5w30 oil thicker than 10w30?

Is 5w30 oil thicker than 10w30?

10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker oil offers better lubrication of motor and engine parts.

What do the numbers mean on motor oil?

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. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures.

What does 10w40 mean in motor oil?

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.

Can I put 10W40 instead of 5W30?

Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.

What do the numbers mean in motor oil?

Single or compound numbers convey the oil’s weight or viscosity; 30 and 10W-30 are examples. With the introduction of new oil additives starting in the 1940s, the compound viscosities replaced single-viscosity motor oil. The “W” refers to “winter.”.

What does the second letter in an oil number mean?

The second letter indicates the level of cleansing protection. They are ordered alphabetically from worst to best. For example, F is better than E is better than D. Don’t confuse “SE” with “SAE,” which you may also see on the can. SAE stands for the Society of Automotive Engineers.

What does the W mean on motor oil?

The W that you’re seeing in the motor oil number stands for winter. So, the number preceding the W is the viscosity of the oil in winter. The lower the number the more viscous, or thick, it’s going to be in cool weather.

What is the viscosity of 5W-20 motor oil?

The first number is the viscosity of the oil, how it will flow, when cold. The second number is the viscosity, how it will flow, when hot. So that means a 5w-20 motor oil will have the viscosity characteristics of a 5 weight motor oil when cold. It also means that it will have the viscosity characteristics of a 20 weight when hot.

Is 10w30 thicker than 5w30? 10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker oil offers better lubrication of motor and engine parts.

Which is better 5W 20 or 10W 30?

When comparing 5w20 vs. 5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

Is 5W-30 or 10W-40 better?

The first number in the motor oil’s name describes the oil’s cold viscosity. 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.

What does 5W-30 mean in oil?

5w30 motor oil has a winter viscosity grade of five, meaning it’s less viscous (less thick) at very low temperatures compared to, say, 10w30. It has a hot viscosity grade of 30, which means it is less viscous at high temperatures than an oil such as 5w50.

What if I put 10w40 instead of 5w30?

Will 5W30 hurt a 5W20 engine?

Using 5W30 oil for your vehicle will not blow out the engine. Your vehicle runs best at 5W20 and this is the type of oil that is recommended by the manufacturer; I always advise customers to use the type of oil that the manufacturer recommends.

Can I replace 5W30 with 10W40?

Is Thicker oil better for high mileage cars?

High-mileage motor oil doesn’t hurt and it could prevent leaks from starting. Some mechanics recommend switching to a thicker (higher viscosity) oil — such as 10W-30 full synthetic oil instead of 5W-20 full synthetic — or using oil additives to stop leaks.

What happens if I use 5w40 instead of 5w30?

In practice, this means that each oil is just as viscous at lower temperatures and will remain viscous at -30°C, however 5w40 oil outperforms 5w30 oils at higher temperatures, being effective up to ambient temperatures of 50°C, as opposed to 30°C.

What does the W in a grade of motor oil stand for?

What does the “w” in a grade of motor oil stand for? 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.

Which is the best rating for motor oil?

It’s always wiser to use the most current API rating for two reasons: Motor oil with any of the current API ratings should still be good to use. If you’re using motor oil with an SJ API rating, proceed with caution. There’s a chance that the oil has expired. Any other API rating is obsolete.

Which is the winter grade for engine oil?

The Society of Automotive Engineers (SAE) defines a numerical system for grading motor oils according to viscosity. The suffixes (0, 5, 10, 15 and 25) followed by the letter W designate the engine oil’s “winter” grade. Look to your owner’s manual.

What’s the difference between 5W20 and 5W30 motor oil?

When comparing 5w20 vs. 5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. This enables the 5w20 motor oil to reach engine parts quicker and create less drag that reduces fuel economy.

Is 5w30 oil thicker than 10w30? 10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker oil offers better lubrication of motor and engine parts. What do the numbers mean on motor oil? The first number in the…
