Question: Is 5w30 Thicker Than 5w40?

Is 5w40 better for high mileage cars?

Both the oils are similar in the fact that they perform well during both cold and warm temperatures.

However, as the 5W-40 oil has a higher viscosity, it offers excellent lubrication during start ups.

It is also great for higher mileage vehicles due to the thicker oil provide better protection for worn parts..

Can I use 10w 40 instead of 5w40?

Aslong as its fully synthetic it will be fine. 5w – 40 will be better for colder conditions, 10w is thicker to start with thus doesnt get to places around the engine as quickly as 5w-40, but it all depends on temperature.

When should I use 5w30 oil?

Using these factors, the 5W30 is your go-to oil when you want something that has a thin enough viscosity for use in cold weather, wider working temperatures and is ideal for light-duty diesel or petrol vehicles.

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.

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.

Can I put 5w40 in my BMW?

BMW says you can use an: 0w40, 0w30, 5w30 or a 5w40 LL-1 oil in the USA. Btw… you can also use a LL-4 rated oil where a LL-1 oil is spec’d, but not vice versa! Maybe who ever changed you oil put too much oil in the engine.

Is 5w40 good for summer?

Be happy; 5W40 is great for summer with the added bennie of great cold start specs. As to interval, you can safely go longer but how much longer will depend on the soot load and fuel dilution. My oil analysis has shown it takes about 5.5K miles for the soot to get up to 0.4-0.6 percent.

What happens if you put thicker oil in your car?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

What happens if I put 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

What 5w 30 oil means?

multigrade oil5W-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)

What is 5w 50 oil used for?

A 5W-50 engine oil is suited for a broad range of applications including motorsport, classic/collector cars and extreme driving conditions like towing and high operating temperatures.

What does 5w 50 mean?

A 5W-50 engine oil will flow like a 5 weight oil in Winter temperatures to protect during cold starts, but maintain the protection level of a 50 weight oil at full operating temperature. Castrol® EDGE®, formulated with liquid titanium, is a premium full synthetic 5W-50 engine oil.

Which is thicker 5w30 or 10/40 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.

Is Thicker oil better for high mileage cars?

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.

What happens if you put wrong oil in your car?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. … Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.

What happens if you put 5w30 in a 5w20 engine?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.

Do oil brands matter?

No. Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. Motor oil manufacturers must meet minimum industry standards for performance and compatibility of the API mark.

Can you use 5w40 instead of 15w40?

5W40 oil will remain suitably fluid (i.e. suitably low viscosity) at lower temperatures than 15W40 oil. Both will operate reliably up to the same outside high temperature.

Can 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.

What oil is thicker than 5w30?

5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. Thinner at lower temperatures. Thicker at lower temperatures.

What does 5w40 mean?

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. Why does the viscosity of engine oil matter?
