Is 5W40 OK for 5W30?

Is 5W40 OK for 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.

When should I use 5W40 oil?

The W indicates cold or winter. 5w40 has a lower viscosity 5 and a higher viscosity is 40. This is crude oil which can be used in a vehicle which has leaded and unleaded gasoline.

Is 5W40 better for high mileage cars?

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 use 5W40 instead of 0W40?

Regardless of fact that 0W40 and 5W40 performs similar duty, both engine oils are not equal in terms of properties and performance. Areas that experience high cold winters may have 0w40 as the recommended engine oil for cars, as it is more effective in lubricating car engine in cold weather (Streather, 2016).

What does 5W-40 oil mean?

5w40 motor 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 0W-40 better than 5W 30?

When it gets hot it’s entirely different, the 5W30 would do a better job because of it’s thick viscosity, it will take more time for it to get thinner than the 0W40 that is thinner. Though both would work very well in Africa, but the 5W30 would do a better job in Africa and the 0W40 will deliver more in Europe.

What does 5W 40 oil mean?

What happens if I use 5W30 oil instead of 5w40 oil?

There are people who race that put in lighter oils so that the engine has less drag and the oil moves through quicker which helps to keep things like turbos a bit cooler. So long as the oil pump can provide the pressure, it works. The only issue I see is that 5w-40 tends to be a VW standard.

Can a 5w40 oil pump work in a VW?

So long as the oil pump can provide the pressure, it works. The only issue I see is that 5w-40 tends to be a VW standard. They also have additive requirements that are not common. If the vehicle is a VW, you might not be protected as intended. The best option is to change the oil again to the proper standard.

What does 5w40 rating on MB R350 mean?

The 5W40 rating is a classification which basically means a certain pour rate at 0 degrees, and a reaction to higher temps (thinning) consistent with a straight 40 weight oil. For instance, my wife’s MB R350 uses a 0w40 or 5w40 (I use 5w40 because it has higher miles and I live in a warm climate).

Can you use variable service oil on a VW?

VW 500.00. This oil can only be used in gasoline engines and is recommended for those which are subject to arduous conditions. It must not be used for any engines with variable service intervals or any which are referred to under other specifications. This is a relatively new oil specification for gasoline engines with variable service intervals.
