Is it appropriate to use ester engine oil for poor power in private cars?

As an engine manufacturer, engine oil is considered as a very important power factor when designing an engine. After we buy the car, we will find the manufacturer's maintenance guidelines for engine oil, transmission fluid, brake fluid, etc., which are very important and recommended that we strictly follow them. Regarding motor oil, I suggest that if you want to achieve brand freedom, you must know two basic standards or certifications, one is the American Petroleum Institute, or API; The other is the European Automobile Manufacturers Association, abbreviated as ACEA, and of course there are many standards set by engine manufacturers themselves, such as MB and so on, which are also based on the above standards.

It's very simple, whether the engine oil we are using has passed the certification of the above standards, just check it....

Ester engine oil is finished after 3,000 kilometers, and it is not suitable for private cars, and is generally used for racing cars.

If you want good power, just use imported PAO engine oil, the power is not much worse than ester engine oil.

The German GT Magic Red power I use now is particularly good, the acceleration is fast, the throttle is brisk, and it is no problem to use it for 10,000 kilometers, and the cost performance is particularly high.

If you choose the all-synthetic one, it will be a little better. You've probably been using mineral oil for this engine. If you travel to the west for a long time, the engine power will be improved less, so it will be better to be fully synthetic.

Hope!!!

This power is not good, and it has little to do with your engine oil, because whether the power of the car is good or not is related to its displacement.

The high temperature stability and wear resistance of lipid engine oil are strong, and the power performance is indeed the strongest, but the oxidation resistance is relatively poor, and the decline is very fast, and it is generally replaced after more than 3,000 kilometers, which is not suitable for private cars.

Now it's best to use a fully synthetic oil

The advantages are good lubrication, good protection at high temperatures, and good performance at high speeds, but the disadvantages are fast attenuation, poor oxidation resistance, high price, and not very practical.

Lipid engine oil is not only ester oil, but also phosphate esters, borate esters, silicate esters, etc. Esters are generally divided into monoesters, diesters, polyol esters and aromatic esters.

In general, the oil forms a continuous film between the two contact surfaces, which acts as a liquid lubrication – preventing direct metal-to-metal contact and thus reducing friction. The ability of a lubricant to provide liquid lubrication depends on the ability to form an unbreakable oil film on two metal surfaces.

First, it affects the wear resistance of engine oil.

Alcohols can easily react with antioxidants (zinc dithiophosphate, hindered phenols, etc.) and anti-wear agents (phosphates, sulfides, etc.) commonly used in motor oils, resulting in reduced anti-wear properties of motor oils. In order to avoid abnormal engine wear caused by the reduction of the anti-wear properties of the oil, it is best to shorten the oil change interval for vehicles using ethanol gasoline.

Second, promote the emulsification of engine oil.

Ethanol gasoline has a 40% lower calorific value than traditional gasoline, is not as durable as traditional gasoline, has a large latent heat of gasification, and is more likely to absorb water. Ethanol gasoline is stored in the engine for a long time, which may produce the phenomenon of oil-water separation, and the water does not participate in the combustion and becomes water vapor when the engine is working. Some of the water vapor is discharged with the exhaust gases, and some of it fuses with the oil in the engine, causing oil emulsification.

Third, reduce the total base value of the oil.

The total base number of engine oil is an indicator for determining the composition of effective additives (cleaning and dispersing agents) in engine oil, which indicates the cleaning performance and neutralization ability of engine oil. Ethanol combustion produces acetic acid and sulfides, which are carried into the crankcase under the cylinder as the piston rings move up and down. The oil needs to neutralize these acids, resulting in a continuous increase in the total acid number (TAN) and a decrease in the total base number (TBN), and when the total base number decreases to a certain level, the oil will gradually acidify and fail.

From the above perspectives, the use of ethanol gasoline will indeed shorten the life of the oil, and the strict emission regulations themselves reduce the content of functional additives in the oil, so the majority of car owners according to the actual situation of the vehicle appropriately shorten the oil change cycle.

Ester synthetic motor oil is one of the synthetic motor oils. At present, according to the base oil, synthetic engine oil can be divided into three types: three synthetic oils, four PAO fully synthetic engine oils, and five ester synthetic engine oils. The most common ester synthetic oils are three synthetic oils and four types of PAO fully synthetic oils.

However, ester synthetic motor oils are less likely to come into contact with our civilian vehicles. This is mainly due to the fact that ester synthetic base stocks are not suitable for civilian vehicles. Ester synthetic engine oil is made of animal fat and vegetable fat as raw materials, processed into ester synthetic base oil through synthetic process, and then blended with additives.

Ester synthetic motor oils offer a number of advantages, such as higher film strength at high temperatures, which can provide strong lubrication protection when the engine is running at high speeds. Compared to other synthetic engine oils, ester synthetic oil can make the engine power output smoother and quieter at high temperatures, making it an excellent choice for racing and tuning cars. However, the disadvantages of all-ester synthetic motor oil are also obvious.

Due to the use of animal and vegetable oils as raw materials, its low-temperature fluidity is not as good as other base oils, and the lubrication effect at low temperatures is also average. In addition, an Achilles' heel of ester-based oils is their poor oxidation resistance, so the oil decays quickly and needs to be replaced after 3000-5000 kilometers. Ester synthetic motor oil is more suitable for racing and modified cars that pursue high speed and high power, and is not recommended for use in areas where the temperature is too low in winter.

If you want to try ester synthetic motor oils, you need to shorten service intervals. There are many oil brands that have oil formulations that take into account both performance and longevity, using both PAO base stocks and ester base stocks. The advantage of PAO base oil Sozu is excellent oxidation resistance and a service life of 15,000-20,000 km.

In the early days of the same hood, by adding PAO base oil, you can make up for the weakness of ester base oil, improve the application range of engine oil, so that family cars can also experience the excellent performance of ester synthetic engine oil.

Ester engine oil has better oxidation resistance and shear resistance, stronger compatibility with metal surfaces, better stability of the additive system, and no harm. It is poor water solubility and easy to emulsify when exposed to water. The oil decay period is short, and 3000-4000 needs to be replaced.

Ester oil was first used as lubricating oil for aviation turbine engines, which was prepared by dehydration of fatty acids and fatty alcohols by esterification reaction under the action of catalysts. Due to the different types of fatty acids and fatty alcohols reacted, synthetic esters can be divided into: polyol esters, diesters, monoesters, etc., and the commonly used synthetic ester base oils are:

Polyol esters, diesters. Generally speaking, synthetic esters have the following excellent properties: high viscosity index, high flash point, low pour point, good fluidity at low temperature, wider operating temperature range, small evaporation loss, good high temperature stability, good oxidation stability, less carbon residue, excellent lubrication, very low toxicity, good environmental protection and biodegradation performance.

Esters are inherently oily, while other base oils require additives to achieve this property. The polarity of esters can make the oil film molecules adhere to the metal surface, so ester oil is the best in terms of residual cavity lubrication performance.

The ester oil we are talking about now refers to natural chemicals with ester groups in their molecular formula. What are the harms of grill ester engine oil, the author will list them one by one for everyone.

Poor water solubility. The water solubility of ester engine oil is relatively weak, and if it is obtained after contact with water, it is very easy to develop an emulsion condition. It not only endangers the main energy performance of the vehicle and the rationality of the fuel, but also aggravates the damage level of the automobile engine.

In the long run, it is very easy for Rava to occur, and it is even possible to destroy it immediately.

The decay period is short.

Compared with other types of engine oil, the decay period of ester oil is indeed short, generally 3000-4000 km. Therefore, it is best to check the condition of the hydraulic oil frequently, and once mildew occurs, it must be changed immediately, otherwise it will endanger the actual effect of the original lubricating oil refrigeration.

**Relatively expensive.

Ester engine oil, can be regarded as a more expensive type of engine oil, although it has better wetting performance and high ridge maintenance characteristics, but if used in some ordinary family car models, it is likely that the practical significance is not very large, and even give full play to the actual effect. Therefore, ester engine oil is indeed somewhat deficient at the practical level, and the decision must be made according to the engine structure.
