What Is 5w40 Oil Used For?

Is 5w50 thicker than 5w40?

5w50 motor oil.

The main difference between the two is the velocity of the oils.

Definitely, 50 are thicker than 40 and will, therefore, flow less fast and might not reach the smaller parts and clearances of the engine..

Can I switch from 5w40 to 5w30?

In most cases, if they recommend SAE 5W-40, then SAE 5W-30 may cause problems with wear or even engine damage. SAE 5W-40 will always be “Thin” enough at any temperature, but SAE 5W-30 may be too “Thin” at high temperatures.

Is 5w30 thinner than 5w40?

Viscosity The working viscosity of 5w30 is basically from 9.3 to 12.5mm2/s whereas the operating viscosity of 5w40 is 12.5 to 16.3mm2/s. That means 5w40 has larger viscosity than 5w30. So, 5w30 is better than 5w40.

What is the difference between 5w30 and 5w40 oil?

Both of these motor oils are 5 grade when cold, however, 5w30 oil is 30 grade, and 5w40 oil is 40 grade at operating temperatures. 5w40 has a higher viscosity than 5w30 with higher temperatures in summer, which adds to the proper running of the car.

Is 5w30 good for high mileage?

Both high mileage 5w30 and 10w30 engine oils have the same additives, the only difference is the viscosity at cold startups. Since both oils have the same operating temperature viscosity (30) and additives, they will perform exactly the same. However, 5w30 flows much better than 10w30 during cold starts.

Can I use 10w 40 instead of 5w40?

10w40 is thicker than 5w40, ONLY when cold. At operating temperature it is exactly the same. … Multi-viscosity oils with a lower W number are specifically designed to flow better, and thus lubricate better, at very low temperatures. There is no need to use a 5w-40 if the vehicle only requires 10w-40.

Can you mix 5w40 and 10w40 oil?

Registered. As long as both oils have the same C-classification, or at least close -no problem in mixing different weights.

Will 5w30 hurt a 5w40 engine?

If you are racking your brain to choose between 5w30 and 5w40, we recommend you go with 5w30. However, if it is too expensive or not available for use, you can always go with the 5w40, which is just as good and will not cause any damage to the engine parts.

Is 5w30 or 5w40 better for winter?

5w30 can be used by different type of vehicles and in different range of temperatures, but is ideal for colder temperatures. 5w40 is often used in higher mileage engine sand performs better in warmer temperatures.

Which is better 5w40 or 10w40?

The 5W40 is thinner than the 10W40 at lower temperatures. But when the temperature is higher, both motor oils similarly perform their intended functions (using the same viscosity). … However, the main difference between these two engine types is that the 5W40 can work better than 10W40 in very cold places.

Is 5w40 thicker than 15w40?

Viscosity is a fluid’s resistance to flow. … Both will have a viscosity of a 40 grade. That cannot be said for both oils during the dead of winter. The 5W-40 will have a lower viscosity when the engine is started than the 15W-40; consequently the 5W-40 will start easier and lubricate quicker in the cold than the 15W-40.

Is 5w40 good for winter?

The choice between 5W40 motor oil and an alternative like 10W40 depends on the winter temperature in your region. 5W40 is better for starting your engine at low temperatures as it flows more easily at these temperatures.

Will 5w40 hurt a 5w20 engine?

5W20 offers better fuel economy than 5W40 and some engines are optimised for using it and lubricating some parts. If you drive short distances only and engine remains cold, then using W40 instead W20 is not an optimal choice.

What will happen if I put the wrong oil in my car?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

What does 5w40 mean in engine oil?

5w40 engine oil has a winter viscosity grade of five, meaning it’s less viscous at very low temperatures, compared to, say, 10w40. It has a hot viscosity grade of 40, which means it is just as viscous as 10w40 at high temperatures but less viscous than oils such as 15w50.

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 temperatures of 50°C, as opposed to 30°C.

Can I put 5w40 in my BMW?

The Castrol oil that BMW used to spec was midway between a 30 and 40 weight. Anything from 0W30 to 5W40 will be fine if it has the LL-98 or LL-01 rating. You don’t even need that if you are running shorter change intervals.
