Is it better to use a fully synthetic motor oil of the same grade?

Engine oil is divided into mineral oil, semi-synthetic oil, and fully synthetic oil. Their base oils are the same, but the additives are different and the models used are different. Fully synthetic motor oil has a high grade and good lubrication effect, so the fully synthetic motor oil of the same grade is better than other engine oils.

Yes, it is best to use the same grade and grade to change the engine oil.

The same grade of engine oil is good.

Fully synthetic motor oils lubricate better than semi-synthetic motor oils. Fully synthetic engine oil has better high and low temperature performance; There are longer oil change intervals; Suitable for harsher vehicle conditions.

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.

The role of fully synthetic motor oils.

1. Lubrication and friction reduction: between the piston and the cylinder, the spindle and the bearing.

There is a fast relative slip between them, and to prevent the parts from wearing out too quickly, an oil film needs to be created between the two sliding surfaces. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

2. Cooling and cooling: Fully synthetic engine oil can bring heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine.

3. Cleaning and cleaning: The fully synthetic engine oil can bring the carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and flush the dirt generated on the working surface of the parts through the flow of lubricating oil.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

4.The main difference between 5w30 and 5w40 oils of the same quality class is that 5w-30 has relatively better fluidity and is more capable of reducing fuel consumption and dissipating heat faster and better in the engine.

Fully synthetic engine oil ** is more expensive, but the service life is relatively long, 10,000 kilometers to change once, mineral oil ** is cheaper, but the service life is short, 5,000 kilometers to replace once, so it seems that the overall cost of the two types of engine oil is about the same, the full synthetic engine oil has strong high temperature oil film strength, high temperature lubrication performance, strong oxidation resistance, good cleaning performance, excellent low temperature fluidity, can effectively avoid cold start wear, uniform arrangement of oil molecules, good silent effect. Mineral oil feels very sticky at room temperature, sticky drawing, but high temperature will become thin lubrication effect is not good, low temperature fluidity is poor, easy to cause cold start wear, mineral oil molecular size is different, mute effect is poor, mineral oil high temperature is easy to produce sludge and carbon deposits, using fully synthetic engine oil you will immediately feel the throttle sensitive, smooth speed, quiet sound, surging power.

The oil is still fully synthetic, and the oil is better than the synthetic oil. Because of the fully synthetic motor oil. More durable.

Safer and more convenient. Use it for a longer period of time. There are also cars that can use 15,000 kilometers per change.

Therefore, it is very beneficial to the maintenance of the engine. It is recommended that you choose a fully synthetic motor oil.

Relatively speaking, the additives of fully synthetic engine oil are more complete than those of synthetic engine oil, and the physical and chemical performance indicators are more stable. Therefore, fully synthetic motor oil is better than synthetic motor oil (in the case of the same brand). **Also fully synthetic motor oil is more expensive.

In the specific use process, the weather resistance and oxidation resistance of fully synthetic engine oil are also better. In the cold start stage of the engine, the fully synthetic engine oil can also give the engine sufficient lubrication protection, and it is not easy to reduce the lubrication effect due to high temperature thinning of the engine in high temperature working conditions. Therefore, it is recommended to use fully synthetic motor oil for turbocharged engines.

The synthetic engine oil is a little weaker in various indicators, ** is also cheaper, and the oil change interval is also a little shorter.

Which engine oil is good, the key is what is suitable for your own car, right? Does it make sense to get a tractor and synthesize it in a circle of your house? Because, I am repaying this suggestion is very big, so your family goes to the contract of Taixi, and then gives you no benefit, so what are you suitable to talk about?

Just talk about what you want, don't just say too much about the pursuit of what is fully synthetic, and then there is no need for the tall, that is, you can eat what is suitable for you, don't just say, it is not appropriate to eat good or coarse grains, so it is best to find a suitable oil for your own home.

Synthetic engine oil is divided into fully synthetic engine oil and semi-synthetic engine oil, of course, it is good to fully synthetic engine oil, and the number of kilometers that can run is also more, and it is more expensive.

Basically, the most important thing is that the quality is good, if the quality is poor, it is better to use mineral oil is the best, ** cheap and safe to guarantee, there is no fully synthetic engine oil in the past, maintenance in place is no problem, what oil to add is not the key, the key is maintenance.

Engine oil is divided into mineral oil, semi-synthetic oil, and fully synthetic engine oil, the best of which is fully synthetic engine oil, which can quickly cool down the engine and fully lubricate the engine.

The so-called synthetic engine oil is generally mineral oil, engine oil is divided into mineral oil, semi-synthetic and fully synthetic, fully synthetic engine oil has the best performance but is also more expensive, and the maintenance and oil change period is longer.

Of course, it is better to have a fully synthetic engine oil, because the special density of the quota ratio is good, so it is still a fully synthetic one that buys a group and earns, and the emission and ghost eyes in the e-liquid measured by the machine will be better.

The mileage of fully synthetic engine oil is longer, generally up to 10,000 kilometers to replace, and the semi-synthetic engine oil needs to be replaced about 5,000-8,000.

First of all, the maintenance time of fully synthetic engine oil is 10,000 kilometers, or one year, while the maintenance time of semi-synthetic engine oil is half a year or 5,000 kilometers.

Fully synthetic motor oil is better than so-called synthetic motor oil. Generally, fully synthetic motor oil is the high-end of all motor oil brands.

There are three main categories of engine oils, from low to high, which are mineral oil, synthetic engine oil, and fully synthetic engine oil. The question you are asking is, of course, that it is good to have a fully synthetic motor oil.

It must be a fully synthetic engine oil, which is better for engine protection.

Hello, in comparison, fully synthetic motor oil is good.

That's a fully synthetic motor oil, of course.

Compared with semi-synthetic motor oil, fully synthetic motor oil has the following characteristics and differences:

1. Fully synthetic engine oil has better high and low temperature performance.

2. Fully synthetic engine oil has a longer oil change interval.

3. Fully synthetic engine oil is suitable for harsher vehicle conditions.

Compared with semi-synthetic motor oils, fully synthetic motor oils have the following characteristics:

1. Good lubrication and cleaning performance.

Base oil for fully synthetic motor oils.

The quality is relatively good, and according to different functional needs, different additives can be added to the oil to achieve different effects, such as adding detergents, anti-wear agents, etc. to improve the ability of wear and clean, so the fully synthetic oil is better than semi-synthetic oil and mineral oil in terms of lubrication effect, anti-attenuation and cleaning ability.

2. Good fluidity at low temperature.

Fully synthetic motor oil has better fluidity at low temperatures than mineral oil in extreme weather in winter.

The fully synthetic oil can minimize the energy consumption of the car when starting at low temperatures, thereby extending the battery life. At the same time, due to the good flow at low temperatures, the lubricant takes less time to reach the individual parts, which can reduce the dry wear of the engine components when they start, thereby extending the life of the engine.

Car maintenance. 3. Less evaporation loss.

Fully synthetic oils are basically pure compounds, and under artificial intervention, the boiling point range is relatively small, so the evaporation is relatively small. At the same time, synthetic engine oil has good radiation resistance and chemical stability, and compared with mineral oil, it also has the characteristics of high oil film strength and less foam. Therefore, generally 4S stores will recommend the use of fully synthetic oil, especially Zen Liang other parts of the high-end models.

4. Maintenance costs.

A barrel of conventional 4L mineral engine oil** is mostly within 200 yuan, semi-synthetic is about 300, and fully synthetic is generally about 400 yuan. If you look at the cost of a single time, fully synthetic is more expensive, but if you think about it in the long run, in fact, fully synthetic engine oil is more economical.

Mineral oil generally has to be replaced after 4,000 kilometers, while the mileage of fully synthetic engine oil can reach 10,000 kilometers or even higher, and the full synthetic engine has better protection for the engine and is more conducive to prolonging the service life of various parts. Taking small maintenance as an example, the average cost of 100 yuan of man-hours, the oil filter element is 40 yuan, according to the conversion of 10,000 kilometers, the cost of mineral oil replacement is about 700 yuan, and the total cost of fully synthetic engine oil is about 500 yuan, obviously the full synthetic engine oil is "cheaper".

1. The base oil is different from the semi-synthetic engine oil, which uses the third type of base oil; The fully synthetic machine mold is judged to be oiled by the first.

Class III, IV and V base oils are blended. Fully synthetic motor oils are one level higher in the choice of base oil than semi-synthetic motor oils.

2. The replacement cycle is different, and the semi-synthetic engine oil is replaced once every six months or 7500 kilometers during use; Fully synthetic engine oil should be replaced once a year or 10,000 kilometers during use; Saibeisa fully synthetic engine oil is changed once every 18 months or 15,000 kilometers.

Three: the applicable temperature is different, the use temperature of fully synthetic engine oil is wider, in the same working environment, the full synthetic oil can achieve the purpose of protecting the engine with a lower viscosity, while the use of semi-synthetic engine oil is relatively high.

Fourth: the applicable vehicle conditions are also different, semi-synthetic engine oil is more economical, small displacement and smooth driving models; Fully synthetic motor oil can be used in a variety of harsh conditions, with good resistance to high and low temperatures. Fully synthetic motor oil is more used in turbocharged engines and high-end luxury cars, and Saibeisa fully synthetic motor oil is the designated engine oil for the Formula 1 racing Red Bull Team.

Five: the use of additives in different fully synthetic engine oils uses additives with high TBN content, so that the longer the oil life, clean the engine; Semi-synthetic motor oils use additives with low levels of TBN and shortened oil maintenance intervals, resulting in sulfide salt ash.

Six: the protection of the engine is different The performance of fully synthetic engine oil is better than that of semi-synthetic engine oil, so the effect of fully synthetic engine oil on the protection of the engine and cleaning the inside of the engine is better than that of semi-synthetic engine oil.

Fully synthetic engine oil is not suitable for any vehicle, for old cars it is recommended to use semi-synthetic engine oil, because the sealing of old cars is relatively poor, and fully synthetic engine oil viscosity is low and fluidity cover is rotten and easy to leak oil, in this case it is more appropriate to choose high-viscosity semi-synthetic engine oil.

In general, if you want to give your car good maintenance, fully synthetic engine oil is still very good

Fully synthetic motor oil is good. There are two types of synthetic engine oil: semi-synthetic and full-limb synthetic oil. Semi-synthetic motor oil has fewer functions because the number of additives is less than that of fully synthetic motor oil, so the mileage and time of use will also be reduced.

Synthetic engine oil: semi-synthetic and fully synthetic motor oil. Fully synthetic engine oil is good!

It is better to use fully synthetic engine oil, especially if the engine is automatically started and stopped, and the better ones are recommended to use fully synthetic engine oil, which is better for the engine.

The best is fully synthetic motor oil, which is better than semi-synthetic motor oil and mineral oil oil.

Summary. Hello dear, happy to answer your <>
