What is the best engine oil for a motorcycle in the summer 5

When choosing engine oil, it is necessary to select the engine oil in strict accordance with the engine oil use grade specified in the vehicle instruction manual, if there is no same level of engine oil, you can use a higher level of engine oil, but it must not be replaced by a lower grade.

Of course, if you are troublesome to change the engine oil, you can also choose multi-grade engine oil for winter and summer, and the scope of application of various multi-grade engine oil is as follows:

Viscosity grade Applicable temperature range ( ).

5w／20 －45～20

10w／30 －30～30

10w 40 30 40 or more.

15w／30 －25～30

15w 40 25 40 and above.

20w／30 －20～30

20w 40 20 40 or more.

The load, speed and wear of the engine must also be taken into account when selecting the viscosity grade of the oil. If the engine is under heavy load, low rpm or heavy wear, you should use a more viscous oil, and vice versa, you should choose a less viscous oil.

Use 15w-40 oil in summer, 10w-30 oil in winter, and 5w-30 oil if it is a cold region, however, few people will ride motorcycles anymore when the temperature is too low in winter, especially scooters.

In summer, the viscosity index is mainly looked at, and the best for w40 or 15w40 is 20w50. Be sure to choose a big brand of engine oil, such as Mobil, Shell, Castrol, etc.

As long as it's real engine oil, there is no difference in general, don't use fake ones, it's no problem, motorcycles are generally very leather, don't be too particular.

In fact. Summer. The weather is already very hot, and the average engine oil will not have an effect.

.Of course, that oil would be more suitable.

It is not advisable to go to places where motorcycles are bought and sold.

It is advisable to go for the purchase of a car.

Generally it is not very expensive to buy, and the average one is about 80 to 90 (4 liters).

Use engine oil that can be used in all seasons.

XGP1981 is not right at all, if you don't know how to fart blindly, okay?

In summer, 10w-40 or 10w-30 engine oil is generally used. Under the condition of ensuring lubrication, the appropriate engine oil is selected according to the temperature range at the time of use, the engine temperature and the actual vehicle condition.

For engines with better vehicle condition and less wear, you can choose lubricating oil with low viscosity, such as 5w30 or 10w30; For engines that often drive at high speeds, continue to run at high speeds, or have a long mileage, lubricating oil with slightly higher viscosity can be appropriately selected, such as 5w40 or 10w40.

Notes:

1. Pay attention to the quality of the engine oil used.

The deterioration of engine oil seriously affects the protection of the engine, so we must choose a quality assurance brand in the selection of engine oil.

2. When changing the engine oil in summer, the oil volume should be slightly lower than the scale on the oil dipstick.

If too much oil is added, it will increase the pressure on the crankshaft of the engine, and reduce the engine power output, increase fuel consumption, and even cause engine damage. The most correct way is to adjust the amount of engine oil according to the change of seasonal climate, not too much in summer, and moderate can be.

3. The viscosity of engine oil in summer is not as high as possible.

Theoretically, you have to use a more viscous oil when the temperature is high, and that's not wrong. However, the current engine oil on the market has changed greatly compared to the traditional usage habits.

Moreover, the current production of automobiles in the selection of new metal materials, processing accuracy, the application of electronic technology and other aspects have undergone great changes, the requirement is a good oil film continuity and fluidity, high viscosity oil is no longer suitable.

All kinds of them are fine, but it is better to use 45 yuan a concubine.

Motorcycle winter use 10W-50 or 15W-40 type oil.

Motorcycle engine oil usually includes motorcycle engine lubricants, motorcycle gear oils, motorcycle shock absorber oils, etc. Splash lubrication has the advantage of simple structure and is conducive to the lightweight of the engine. However, the lubrication effect is often poor, especially for each bearing, and it is difficult to fully lubricate the oil from the outside.

I think it's best to use a fully synthetic motorcycle engine oil when you can.

1. Some people believe that fully synthetic engine oil has better lubrication effect than ordinary mineral oil. In this way, there is less mechanical loss and the motorcycle can run faster. I think such an idea is wrong.

2. What affects the friction power is the viscosity of the engine oil. Replace the fully synthetic engine oil, the high-temperature fluidity remains unchanged, of course, the friction power does not necessarily decrease, and the output power of the engine does not necessarily change.

3. However, the use of fully synthetic engine oil for motorcycles can extend the life cycle of the engine. The main role of motor oil is lubrication, sealing, heat dissipation, and rust prevention, and compared with mineral oil, the molecule is small, compact, and has high fluidity.

4. The speed of motorcycles is often relatively high, and the most obvious effect of using fully synthetic engine oil is that the engine wear is small. With less wear, the overall life of the engine is extended.

5. When conditions permit, it is best to use fully synthetic engine oil. Although ** is a bit high, the overall cost is not necessarily higher than mineral oil, given the long decay cycle.

6. Of course, it is best to use mineral oil during the grinding and laughing period, but the use of synthetic engine oil will affect the running-in.

7. In addition, the choice of motorcycle oil also depends on the characteristics of the engine, and the structure and characteristics of the powertrain are different regardless of the gear. Generally, single-cylinder low-rotation engines, as long as the most common mineral oil is used, the grip volt will not achieve the effect of lubrication. Multi-cylinder high-** engine oil should be selected as much as possible, so as to better protect the entire motorcycle.

Motorcycles use winter engine oil in summer, which can lead to wear and tear on mechanical parts. Motorcycle winter should choose compound viscosity oil to ensure the low temperature fluidity of the oil. Each type of motor oil is clearly marked with its number, such as 10w40, the smaller the number in front of the w, the lower the minimum temperature he can use, and the larger the number after the w, the higher the maximum temperature he can use.

Therefore, when using engine oil in winter, we should pay more attention to the previous figures, and under the premise of economic affordability, the smaller the better.

The problem is not very big, the oil has resistance to the highest temperature, but after the car runs, the air-cooled car, the engine has the highest temperature, and the summer and winter are not too much! Regular engine oil is enough! Save money.

It's just that the heat dissipation effect is different, and the heat dissipation effect with engine oil is better in summer. The engine is not so prone to high temperatures.

The oil is sticky in summer and the oil is thin in winter, if the oil is hard in summer, the oil will not pump in the oil, and the parts that need to be lubricated are not well lubricated, which will aggravate the wear of the engine and reduce the service life.

To put it simply, the oil in winter is very thin, the oil in summer is very thick, the oil in winter becomes thinner in summer than in winter, the viscosity is not enough, and the oil becomes the same as water after the engine is hot. The downside is that it increases wear and tear!

The viscosity is small, and the oil film cannot be formed, and it is easy to wear and tear.
