10 Langyi plus what oil is good, thank you, 1 6 since

The higher the marking, the better the protection at high speeds, and the cylinder will not be pulled. However, the viscosity is high, the resistance is high, and the low speed is oil-intensive. However, when the car reaches the optimal temperature, 95 degrees, and the oil reaches more than 100 degrees, the high-grade engine oil will also become thinner, and the resistance will be small at low speeds.

In short, the high-grade ones are definitely good. But with 40 or 50 full synthetic oil, the turbine is needed. Because you also have to consider the wear of the turbine, and the viscosity of the oil turbine seal is good, it will not burn the oil.

Turbines also need oil to lubricate and cool the car, add 40 semi-synthetic oil is OK. 5W-30 in winter 15W-40 in summer. Or drive less, use 10w-40 all-season engine oil.

If the engine can start smoothly, do not use winter oil, because the winter oil is too thin, shear resistance, and the speed should not be too high. And to reach the optimal temperature, thinner, easy to pull the cylinder. If you're purely trying to save fuel, you can use thin oil, but don't rev more than 2000 rpm and don't accelerate sharply.

Because rapid acceleration at low rpm is the main culprit that leads to carbon deposits. Moreover, rapid acceleration at low revs, just like a person riding a mountain bike with a low cadence and pressing hard to accelerate, will cause a large accumulation of lactic acid, which is not carbon deposit. And it will destroy the knee, isn't this easy to break the piston linkage?

Taxis love to do this, thinking that they are fuel-efficient, but they are not fuel-efficient. Too thick gasoline and thin air, low efficiency, slow acceleration, and fuel consumption.

Castrol SL10W-40, this one is good.

A 5W-40 viscosity oil is required.

Take "5w-40" as an example, look at the label of engine oil, mainly look at two values, the first is the main label, which is the "5w".

1. Where W stands for Winter is the meaning of winter, which is divided into 0W, 5W, 10W, 15W, 20W, 25W;

2. The higher the value in front of W, the better the low-temperature fluidity of the oil, the lower the ambient temperature that can be used, and the better the protection ability of the engine in the low-temperature environment, 5W is the minimum temperature -30. Therefore, in extremely cold areas, the worst must be 5w, otherwise the engine oil will freeze in winter.

Methods of oil selection:

It is best to use multi-viscosity lubricating oil when choosing engine oil, lubricating oil (also known as multi-grade lubricating oil) has the nature of light oil at low temperature, and has the nature of heavy oil at high temperature, and in the case of recommending the use of multi-grade oil, a multi-grade oil can replace a variety of single-grade oil.

Although multigrade oils are suitable for extremely cold and warm seasons and heavy-duty engine oils, especially those that do not have difficulty starting in cold weather, a single viscosity lubricant is often recommended to facilitate engine lubrication and extend engine life.

1. Volkswagen Lavida PLUS currently needs to use 5W-40 viscous engine oil, which is more suitable for German models. In fact, there are many reasons for the fuel consumption of the vehicle, such as our driving habits and the road we are driving will affect the fuel consumption.

Driving and maintaining a car, maintenance is inevitable, and engine oil is the most important part of maintenance. I often see friends in the car group discussing what kind of engine oil to use, "self-priming semi-synthetic is enough, full synthetic is too expensive, wasteful", "fully synthetic is good, good for the engine" ......There are a variety of opinions. Today, Lao Yu comes to talk about my shallow views, only representing personal views, and welcomes riders with different opinions to come**.

Let's talk about the difference between fully synthetic and semi-synthetic engine oil (mineral oil will not be discussed): fully synthetic engine oil is made by chemical methods, decomposing natural substances and then synthesizing with various other substances, and finally forming engine oil, fully synthetic engine oil does not have any mineral oil components! And there is some mineral oil in the composition of semi-synthetic motor oil!

Secondly, in terms of base oil, the base oil used in the fully synthetic engine oil is much better than the semi-synthetic base oil in the same environment, whether it is high temperature lubrication performance or replacement cycle, especially in terms of lubrication performance, the base oil used in the full synthesis can be warmer and moisturized! Moreover, the oil film adhesion time of fully synthetic motor oil is much longer than that of semi-synthetic motor oil, which is why fully synthetic motor oil is more durable than semi-synthetic motor oil!

Fully synthetic oils are used at a wider temperature and have a longer service life; The same oil film requirements can be achieved with a lower viscosity of synthetic oils, while semi-synthetic oils need to use a higher viscosity than synthetic oils to achieve such requirements. In other words, in the same operating environment, a fully synthetic oil can protect the engine with a lower viscosity.

To sum up, it is summarized that: 1. Fully synthetic engine oil has better high and low temperature performance; 2. There is a longer oil change interval; 3. Suitable for worse vehicle conditions.

After talking about the difference in performance, let's talk about the difference in maintenance costs: take the fully synthetic engine oil and semi-synthetic engine oil in the 4S store as an example.

Original engine oil. Fully synthetic** 448 yuan (488 yuan in some areas), semi-synthetic 288 yuan, oil filter element 45 yuan, working hours 120 yuan. Calculate the total maintenance cost of the two (according to the replacement of 7,000 km of semi-synthetic and 10,000 km of full synthesis), as shown in the following table:

Comparison of maintenance costs.

The above is a rough calculation of the maintenance cost of different oils (semi-synthetic oil is changed more frequently than fully synthetic oil, and this calculation does not take into account the round-trip distance and time cost of each maintenance). Taking 100,000 kilometers as an example, it takes more than 6 years for most cars to run 100,000 kilometers, and it costs more than 600 yuan to use fully synthetic engine oil in 6 years, with an average of 100 yuan per year! (Riders will ** fully synthetic engine oil 300 yuan, which is cheaper than semi-synthetic engine oil).

What do you get in exchange for spending an extra $100 a year? Let's think about the difference between fully synthetic and semi-synthetic motor oils.

Piston strain. Lao Yu believes that even if it costs a few hundred more yuan, the difference in the maintenance effect of the engine is far more than a few hundred yuan. The engine starts cold, runs at full load or even overload, and the protective effect brought by different oils is also very different, and besides, some engine strains are irreversible. So, I think a fully synthetic motor oil is not a waste, but a wise choice.

1. Volkswagen Lavida 2019 car, under normal circumstances, it can add 5w30 engine oil, it is recommended that you try to use fully synthetic engine oil, so that the protection of the engine will be better.

2. Semi-synthetic is fine.

3. Semi-synthetic and fully synthetic.

19 new Lavida should use 5w to 40 engine oil.

The manufacturer requires the use of synthetic engine oil that meets the Volkswagen engine oil certification standard, and the viscosity of the engine oil is 0w-30 5w-30 0w-40 5w-40, and you can use the viscosity of that oil.

It is recommended to use 5w-30 oil viscosity for new cars, and if it is a mileage of more than 8-100,000 kilometers, it is best to use 5w-40 0w-40 oil viscosity is better.

As for the engine oil brand, it is not very important, mainstream brands can use it, and Volkswagen's original engine oil also uses many brands such as Mobil, Shell, Castrol, etc., you can choose according to your own ideas.

Lavida is suitable for Mobil oil, this oil is recommended.

Mobil Oil adheres to synthetic oil technology and likes to go through the technology flow. Mobil basically prefers to follow the technology flow, and has always insisted on the development of this synthetic oil technology. The biggest advantage of its synthetic oil is that it is not easy to crack, the oil change cycle is relatively long, and the performance of this sports performance is relatively good, and the high-temperature performance is also quite good.

It sounds like a lot of advantages, but it's all generated by a technology. That is, they have developed their own base oil called polyolefin, which is patented by ExxonMobil, and the abbreviation is called PAO in the local English alphabet. It is ethylene and propylene dispersed from gas and natural gas in the first place, and then polymerized and catalyzed by professional equipment, anyway, a very complex pair of chemical reactions, and then refined from this base oil.

Its base oil molecules are arranged very neatly, and then the ability to resist external variables is very strong, what extrusion, oxidation, thermal stability effects, viscosity changes, and resistance are better, then this is the trick, he hit all over the world.

Mobil motor oils perform well in sport. Many manufacturers who choose Mobil motor oil tend to pay more attention to performance, for example, many German cars, fast performance cars, and more Mobil products. There are also some economical cars of this kind, which change the oil once every six months.

The oil change once every 10,000 kilometers and 15,000 kilometers is Mobil.

Mobil oil changes are available for a longer period of time. Mobil is a little more powerful, if it is combined with its long-term filter, it can change the engine oil once every 25,000 kilometers, which is quite durable. Therefore, if you use Mobil oil, the 4S store tells you that 5000 is a change, which is a bit overkill.

Lavida is suitable for using SJ-grade mineral engine oil with 5W40, and Shell engine oil can be used.

The power performance of the machine is not abundant, but it is definitely enough for home transportation. EA211's machine is relatively reliable, unlike the big brother EA888 that is not worry-free. There is no turbocharging, which is also beneficial, and the later maintenance is cheaper than the machine.

In the entire compact family car, the performance of Lavida is not the best, but it seems that the Chinese people pay more attention to the Volkswagen brand. In general, Lavida's home transportation is still good, and it is not called value preservation in the later stage.

First of all, Volkswagen's cars, the overall reliability is still okay, otherwise it would not have saved such a good reputation in China (although it has declined in recent years), and Volkswagen's cars, the reputation of A-class cars is better than B-class cars.

As we all know, Jetta Santana leather is durable, but few people say that the Magotan Passat is durable, because the simpler the structure of the car, the lower the failure rate, like the Jetta Santana, which is a purely mechanical car, and there is not too much advanced technology, so the failure rate of the car must be low, but compared to the Magotan Passat, EA888 engine, dual-clutch gearbox, timing chain, timing gear jumping gear, etc., so the Volkswagen's car is also recommended personally, but the A-class car is recommended.

Lavida is suitable for Mobil oil, Speedmaster 2000, this oil is very suitable for Lavida, and it is not expensive.

Mobil motor oils are ultra-high viscosity synthetic lubricants with superior performance designed for heavy-duty, low-speed gears that are often border-lubricated. These products are formulated with synthetic base oils, which have such a high viscosity grade but still have a unique low-temperature flowability. These ultra-high viscosity products can be pumped over long distances and can be used with standard oil spray application equipment.

The engine oil on the market can be divided into two types: mineral oil and synthetic oil due to its different base oils (vegetable oil is not counted due to the scarcity of production). Synthetic oil is divided into: fully synthetic and semi-synthetic.

Lubricating oil base oils are mainly divided into two categories: mineral base oils and synthetic base oils. Mineral base oils are used in a wide range of applications in large quantities (about 95% or more), but some applications require the use of synthetic base stock blends.

In fact, for most car owners who like to add fully synthetic motor oil, they will find that the proportion occupied by Mobil is relatively large, after all, Mobil's main product seems to be fully synthetic, although other motor oil brands have it, but Mobil may do it more meticulously and more refined.

Lavida is suitable for use with VW502 or VW504 certified oils, and the same Mobil One or Castrol Magnet 5W30 is available in different versions.

Mobil One contains active cleaners to prevent carbon deposits and sludge deposition, keeping the engine clean and extending its life for a long time. Excellent thermal and oxidative stability, delay the aging of lubricating oil, and extend the oil change interval; Low oil consumption to reduce low-carbon hydrogen pollution; Good friction properties High fuel efficiency.

Castrol Magnetics' smart molecules attach to critical engine components, so from the moment you twist your keys, it protects your engine before, during and after your journey, minimising wear and tear.

As the engine heats up, about 75% of the wear occurs at this stage. But even after your car is turned off, Castrol Magnet's smart molecules will continue to attach to your engine, dramatically reducing wear and tear during this time.

Lavida is suitable for mineral engine oil, here I recommend everyone to use Dutch Shell mineral engine oil.

1. Economy, Lavida does not consume fuel, only hybrid cars in the same level will be more fuel-efficient than him, and the fuel consumption of most models of the same level is similar to Lavida. Even at pure high speeds, I don't think this fuel consumption is high. The number of Lavida is obvious to all, and this is also a guarantee of a low zero-to-whole ratio, and the parts are easy to find and repair the car is not expensive, not to mention that there are not many problems.

2. Driving experience, the balance between the direction directivity of Lavida and the positive torque of the steering wheel is very good, the directivity is reasonable, and there is no positive moment, it is very tiring to drive, and it is very comfortable to drive. The throttle tuning is very linear and very well controlled. With such a driving experience, who in the same class is more in line with the needs of the public.

Lavida can be said to be very good to open. Fox is certainly more sporty, and there is no one of the best directives in this class, but the sacrifices made by Focus do not meet the needs of mass consumers.

3. Comfort, Lavida's NVH does not have a great advantage, the noise problem does exist but it is not too much, and it is basically acceptable. But the ride aspect is very well done. Lavida doesn't bump and doesn't make people feel shaky.

The tuning is moderate and suitable. Lavida's space has certain advantages in the same class. The practical aspect is handled properly.

Ergonomics are no problem either.
