Can I use 5w40 engine oil?

Hello, there is no problem with 5w40 engine oil, fully synthetic engine oil can be used completely, don't worry.

Good afternoon, this depends on the specific model, this is a semi-synthetic engine oil, suitable for use in areas with a minimum temperature of -30 or above, and can be used in general engines. For turbocharged vehicles, it is best to use fully synthetic motor oil. Semi-synthetic engine oil can be changed every 7500 kilometers or every eight months, and it is recommended to maintain it in advance.

5W-40 engine oil is used in most areas, so it can be said to be a general purpose engine oil! 5w represents that it can be applied to winter, and that 5 refers to low temperature start-up, as long as it is not too cold, it is not used 0w! 40 represents the high temperature performance, the higher the value, the better the high temperature protection.

Hello, it depends on the specific model, if the model of the engine oil used in the model is 5w-40, it can be used.

This grade of engine oil belongs to a four-season engine oil, you can choose, but it also depends on what brand.

Hello, this depends on your specific model, but most cars use this grade of engine oil.

Hello, this first thing is to see what kind of model you are, in fact, to see what brand and what grade of engine oil you choose? This is only a motor oil viscosity, which is generally suitable for most parts of the country.

Hello, this mainly depends on whether your model is suitable or not, and it is recommended to choose a big brand of engine oil.

Hello, this question depends on what type of car you are talking about, and it can be used under normal circumstances.

Yes, but it is more suitable for use in summer, and it can be lowered by one viscosity in winter.

Hello dear, the main reasons why it is not recommended to blindly use 5w40 engine oil are as follows:1Not suitable for low temperature environments:

The first number "5" of 5w40 motor oil represents its flow properties at low temperatures. Although 5w40 engine oil is more suitable for winter use in cold areas, if it is used in a high-temperature environment for a long time, it will lead to problems such as oil film rupture and leakage. 2.

Reduced engine performance: The relatively high viscosity of 5w40 oil may create more friction and drag when the engine is keyed, which can affect engine performance and fuel efficiency. 3.

Not suitable for certain vehicle models: Some car manufacturers may specify specific oil viscosity grades, and the use of other specifications of oil may affect the car's warranty or cause engine damage. Of course, whether to use 5w40 engine oil also needs to be determined according to the specific situation, you need to consider the year, brand, type, climate and environment of the vehicle and other factors, choose the best oil for your own vehicle is the most important.

The choice of engine oil is very particular, the owner can choose the oil can be combined with the local maximum and minimum temperature, the grade of the vehicle and the condition of the vehicle to choose, if the choice of too viscous oil, will increase the movement resistance, affect the engine power.

If you choose an oil with too little viscosity, the lubrication quality cannot be guaranteed, and it will aggravate the wear of the engine. For engines that have been seriously worn and the gaps between the fittings are large, a higher viscosity oil can be used to strengthen the sealing performance of the fittings.

To put it simply, it is better to choose a thinner engine oil for new cars, and it is better to use a more viscous engine oil for cars with higher kilometers.

How to choose the right 5w40 engine oil!

I should use 5w40 engine oil, but I use 0w20 for maintenance, will it have an impact? As long as that number doesn't change, it's fine.

It is recommended to use the appropriate type of engine oil The model is classified according to low temperature characteristics and viscosity The wrong model will cause increased fuel consumption and decreased power.

If the car does not have special requirements for engine oil, 5w40 will do.

Hello Hello I am very happy to answer for you: the high viscosity of 5W-40 engine oil will increase the movement resistance of the engine, increase friction and energy loss, and at the same time have poor fluidity in low temperature environment, which may affect the starting, acceleration performance and fuel consumption of the engine, and is not conducive to the lubrication of the old engine, there is a risk of blockage, and long-term use does not meet the recommendation of most car manufacturers, so it is not recommended to use 5W-40 oil in all models and engines. 5W-40 engine oil is a fully synthetic engine oil, and the main reasons why it is not recommended for use in certain models and engines are:

1.The viscosity is too high and the fluidity is poor. The kinematic viscosity index of 5W-40 engine oil is relatively high, and the viscosity is also high at low temperature, which will affect the fluidity of the engine oil in the engine, which is not conducive to the oil reaching various parts in a short time.

This has an impact on engine cranking and low-temperature performance. 2.Increased fuel consumption.

The high viscosity of 5W-40 engine oil will increase the thickness of the oil film inside the engine, increase the friction of the engine, and accelerate the deterioration of the engine oil caused by the lead trace, which will increase the fuel consumption of the engine. 3.Not suitable for older engines.

The internal mechanism of the old engine is rough, the sealing is poor, and the high-viscosity oil is not easy to reach all parts of the engine in a short time, which is not conducive to the lubrication of the engine and will accelerate the wear of the engine. 4.Not in line with engine manufacturer recommendations.

Most car manufacturers and engine manufacturers will recommend specific viscosity grades and product grades in the engine manual, and the viscosity and performance of 5W-40 oil may exceed their recommended requirements, and long-term use will affect engine performance and service life. 5.There is a risk of foreign body blockage.

5W-40 engine oil has poor fluidity, and there are many precipitates in low temperature environment, which is easy to produce foreign substances such as sediment and oil fatty acids, which may block the oil filter and lubrication system after long-term use, and affect the lubrication of the engine.
