Can I use 5w40 instead of 5w30?
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.
Which is better 5w30 or 5w40?
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.
Is 5w30 or 5w40 better for summer?
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.
What’s the difference between 5w30 and 5W 40 oil?
Difference Between 5w30 and 5w40
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.
Why is 5w30 more expensive than 5w40?
5w40 oil is not thicker has it has a higher viscosity. 5w30 has lower viscosity hence it is suitable to use in hot or lower temperatures. 5w40 has higher viscosity hence it is not suitable at all temperatures. 5w30 is an expensive engine oil as compared to 5w40.
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.

When should I use 5w40 oil?
5w40 is better for starting your engine at low temperatures as it flows more easily at these temperatures. When the engine is running and hot, 5w40 and 10w40 have high viscosities and are equally effective in protecting against engine wear.
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 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.
Is 5W30 good for summer?
5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts.
Is Castrol EDGE 5w40 fully synthetic?
Castrol Edge 5W-40 Advanced Full Synthetic Motor Oil, 5 Quarts.
Is 5w40 good for winter?
An oil’s viscosity is its resistance to flow. 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.
Can you put 10w40 in a 5w40 engine?
Yes. 10w40 is thicker than 5w40, it will not lubricate all the parts that need lubricating from cold.
Is Castrol EDGE high mileage good oil?

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. You may give up enhanced performance if you switch from synthetic or high mileage to conventional oil. MYTH: When motor oil becomes dark, that means it’s time to change it.
