Which oil is better than shell or castrol. Which engine oil is better: Shell, Mobile or Castrol? Recent developments and beneficial properties of Castrol oils

The performance of a car engine largely depends on the type of oil its owner uses. On Russian market there are several types of engine oils to ensure reliable operation vehicle in a wide variety of conditions. Among them are Shell and Castrol, between which some car owners cannot decide. Let's try to figure out which engine oil better: Shell Helix or Castrol, and what exactly.

Shell or Castrol: the dependence of the choice of oil on the car

To choose a car oil that is best suited for a specific car and ensures its reliable operation in certain conditions, you need to know its quality. The basic requirements for lubricants are always the same:

• Provide good starting characteristics to the motor. That is, it should start easily in both heat and winter.
• Reduce friction of parts, ensuring good acceleration of the car.
• Allow the engine to reach maximum power quickly.
• Comply with environmental safety requirements.
• When operating the machine, oil consumption should be kept to a minimum.

The performance of lubricants in an engine depends on the technology by which they are made.

When choosing which is better, Shell and Castrol, it is imperative to pay attention to the marking on the container. If the brand of the car for which the lubricant is purchased is marked on it, then it can be used.

As for the choice of the composition - synthetic, semi-synthetic or mineral, this is taken into account on the basis of what kind of oil is currently poured into the engine. Usually the best is a mixture with a synthetic base (except for cars with a worn engine).

The marking on the container will allow you to find out to what extent the lubricant provides protective properties for the motor parts.

When it comes to the presence of additives, then Shell and Castrol contain equal amounts of phosphorus and magnesium. At the same time, the former has barium and sulfur to a greater extent.

As tests show, Shell helix preferable to use in steel engines. As far as Castrol is concerned, this oil can work equally well in motors made of steel and aluminum.

What is oil waste

When the engine is running, some of the lubricant always burns out. This part may be quite insignificant, but it happens that the degree of consumption of engine oil due to waste is quite high. Combustion directly depends on such a parameter as the viscosity of the composition. If its level is optimal, then increased consumption not happening.

Oil burnout also negatively affects fuel consumption (both gasoline and diesel fuel). If it is negligible, then fuel is saved. Both Shell Helix and Castrol have rather high characteristics in this regard.

What does the viscosity of the oil affect?

The qualities that ensure a confident engine start are directly dependent on the viscosity of the lubricant. If it does not crystallize in the cold, then the engine starts easily. It does not need to be warmed up and, using prolonged rotation with the starter, pumped along the entire lubricating chain.

In this respect, both Shell Helix and Castrol perform well, but Shell is somewhat better.

It should be emphasized that Shell Helix qualities make it easier to start the engine at extremely low temperatures. But even in those areas where winter is not so severe, the use of this engine oil is preferable.

A quick start of the engine is ensured by such an indicator as the viscosity index. If it has a high value, then the launch is better.

Shell has a viscosity index of 155. The viscosity of Castrol is 147. What does this mean? Of course, Shell will not provide the ability to start the engine unheated at temperatures typical of the High North. There are special lubricants for such conditions. But still, if the frost is within 35 degrees, then the engine will start without difficulty.

Detergent qualities of oil

The task of engine oil is not only to provide lubrication to the rubbing parts of the internal combustion engine, but also to protect them from premature wear that occurs when contaminated. It is caused by deposits that form when the motor is running.

Their formation is directly dependent on volatility, which is determined by the combustion temperature in the working chambers of the cylinders.

To clean the engine from deposits, to prevent their formation, additives with detergency are added to engine oils. They give an alkaline reaction. Shell is leading in this regard. However, at the same time, the degree of volatility is also higher.

Which oil is better: Castrol or Shell Helix for price and quality

It is known that some car owners, when purchasing lubricant for an internal combustion engine, are guided by its price. Sometimes, trying to save money, they choose what is cheaper. Unfortunately, such savings, under certain conditions, can turn into additional costs.

In terms of cost, Castrol is the leader among oils on the Russian market, while Shell is cheaper. Although, as studies have shown, Shell still surpasses it in a number of qualities. A good engine oil that will keep your engine running reliably and long does not always cost more.

Choice machine oil for the engine of your car - this is a responsible job of every motorist. But when you have to choose between the brands Mobil and Castrol, which are considered the most famous and demanded in the world, making decisions is not as easy as it might seem.

Both manufacturers have their own advantages, history, performance and quality standards. It is difficult to figure out which brand is better, but it is worth trying to figure it out.

British brand Castrol - one of the most famous in the world, has a large number of production facilities, mainly in Germany.

The manufacturer relies on high-tech production and its own research and development. The company's portfolio looks great with items regarding cooperation with the most powerful auto concerns in the world - BMW, Man, Land rover, Volvo, Skoda, Seat.

Castrol develops engine oils for all types of engines and vehicles, including the production of entire lines specifically for the world famous car brands... For all its merits, Castrol's main approach to distributing its products is to offer a high quality product with a pricing policy that is flexible enough for this level.

What qualities of its products does the Castrol manufacturer offer:

• Castrol oil makes it easier to start the engine from a cold state;
• low volatility products;
• anti-friction and antioxidant properties;
• prevention of foam formation;
• economy of fuel consumption;
• reduced level of sulfur components;
• improved detergent properties;
• protective action against mechanical shock of the engine.

Recently, the main feature of the manufacturer's products remains technological development Intelligent Molecules. A separate line of Magnatec oils that utilize this technology allows the oil to be used throughout its entire life with consistent viscosity stability.

Mobil - United States of America

Mobil is the global market leader in motor oils. Exxon-Mobil, which develops a wide range of lubricants for various purposes under this brand, gained its popularity thanks to the most famous Mobil 1 oil.

Thanks to successful development, the company found partners (Porsche, Cadillac, Mercedes benz, Dodge), which are also world famous. The company's developments have become popular among most fans of motor sports due to its widespread use and advertising in various competitions.

Mobil's main bets in oil development are:

• engine protection and stable fluidity even in the cold season;
• high degree of purification;
• profitability by increasing engine efficiency;
• thermal stability and protection against oxidation during intense heating;
• long-term preservation of engine performance.

Among the main developments of the company are technologies to protect the engine from wear and clogging. This allows distributing Mobil brand oils among owners of not only passenger cars, but also trucks as well as vehicles used in extreme operating conditions.

It is not easy to answer the question: "Which engine oil is better: Shell, Mobil, Castrol?" We have selected several characteristics by which we will compare these brands.

There are a lot of brands, well-known and not so well known. I want to buy quality products. Shell, Mobil, Castrol are famous brands motor fluids competing with Motul, Zeke and Esso. When choosing a mixture for a car, follow the rule: the liquid must meet the following requirements:

1. Low consumption during vehicle operation;
2. Provide maximum power and dynamics to the power unit;
3. Be environmentally friendly;
4. Have good starting characteristics.

Environmental friendliness and safety

Depending on the processing technology and the quality of the material used motor fluids with the same marking will behave differently in the motor. This is due to the different base base and additives used. Obviously: when choosing between the brands Shell, Mobil, Castrol with the same base, it can be synthetic, semi-synthetic and mineral, preference should be given to oil, on the canister of which there is an approval of the manufacturer of the brand of your car. According to the base of the liquid, a mixture with a synthetic base will be the best, but the tolerance makes it clear that on a certain type of engine this liquid copes with the protective properties.

Having studied the qualitative composition of these lubricants, we came to the conclusion: the amount of phosphorus and magnesium is the same for all brands, and Shell has much more barium and sulfur than its competitors. But Mobil oil breaks out as the leader in protective properties motor due to the high content of molybdenum. Comparing the chemical elements of the structure of these lubricants, it is obvious: Mobil works better in aluminum engines, Shell - in steel ones, Castrol takes an intermediate value, it can be used in both types of power units.

All three brands provide good performance the performance of motors, prevent abrasion of the internal elements of power units. But harmful emissions the atmosphere is less for Castrol.

Waste consumption

In the friction units of the drive, a certain amount engine mixture goes to waste - burns out during the operation of the piston group. Thus, the volume of the mixture leaving for waste affects the efficiency of the fluid, indicates whether it is necessary to add oil between planned replacements. This parameter depends directly on the viscosity characteristics of the lubricant. With optimal viscosity, the engine works perfectly and does not consume excess fuel; in other cases, an increase in diesel fuel or gasoline consumption is observed.

According to the specified parameter, Mobile breaks out into the lead, but its victory is not so significant, this brand differs from its competitors by a lower consumption of only 3%. Therefore, we can say that all brands are kept at a high level, provide fuel economy by 8%.

Watch a video about the different properties of different brands of motor oils - this will help you answer the question: "Which motor oil is better: Shell, Mobil, Castrol?":

Starting properties

In search of an answer to the question: "Which engine oil is better: Shell, Mobile or Castrol?", We could not leave aside the starting properties. They depend on the viscosity of the mixture - the ability of the liquid not to crystallize at low temperatures, to ensure that the engine starts without warming up and the mixture is pumped through the lubrication system. And also take into account mechanical losses for starting the starter. According to these parameters, Shell is in the lead, followed by Castrol, the last place is taken by Mobile.

This division is very arbitrary: the leader ensures that the motor starts at the lowest temperature. But this does not mean that you live in a region where you need an oil with the best starting properties, perhaps the low-temperature indicator of Mobile is enough for you.

Price

The cost of products for motorists is of great importance: I want the price to correspond to the declared parameters of the liquid. Software of the specified category highest cost has Castrol, but for good oil it is not a sin to overpay. Shell is in second place and Mobile is the closest in terms of price to the consumer.

Many car enthusiasts note: Mobile does not differ in quality from foreign brands, it does an excellent job with protective functions.

Conclusion

Answering the question: "Which engine oil is better: Shell, Mobil, Castrol?" These brands have good detergent, anti-corrosion, anti-wear properties; a small amount of lubricant is used for waste. We were not able to choose an obvious leader in all categories, so when buying these brands, follow the recommendations of the manufacturer of your vehicle and pay attention to the tolerances.

Choosing motor fluids of these famous brands, be careful not to get a fake.

Any motorist, even one who does not have much experience, understands that the presence of a lubricant is simply necessary for a car. Without such a fluid, mechanical components and assemblies will simply fail, while the car will not even go far. In fact, the aspect of choice is extremely important, you should only purchase a high-quality substance, confirmed by the manufacturer's warranty and approved by the vehicle manufacturer. If you buy a good oil, the interacting mechanisms will function for a long time and trouble-free, delighting the owner of the car. In the material below, we will consider the products of branded companies, find out which oil is better - Shell or Mobile, comparing them with. High-quality lubricating fluids not only reduce friction between system elements, but also resist oxidative processes and cool hot parts.

Comparison of Mobil, Shell or Castrol motor oils.

Engine oil selection criteria

If a motorist does not know what to rely on when choosing a lubricant, he should, first of all, turn his attention to the product of a foreign manufacturer. Generally, all motor fluids can be classified. The substances are different from each other in composition, in stores you can buy mineral lubricants that are considered basic (they are created by the method of selective cleaning, with the removal of paraffins by means of a solvent); minerals that have been hydrotreated; as well as greases that have the highest viscosity grade.

Engine fluids that have the highest level oxidative stability, as a rule, have excellent viscosity, they do not contain paraffins. This class includes exclusively basic synthetic fluids without harmful admixtures of sulfur and metals.

Manufacturers also create ones that are based on plant extracts. Such substances have high level the resistance of the outer oil film. Their main advantage is considered to be the ability to flush the power unit, showing good thermal and antioxidant functions. It is believed that the most the best oil, which exists today, is a grease formulated using GTL technology. This substance is produced exclusively by Shell, in which this grease is called Pennzoil.

Differences between oils in chemical properties

If a car enthusiast doubts which oil is better - Shell or Mobile, he should take into account that almost all modern motor fluids contain substances of several categories described. In addition, in them, thanks to which it is possible to hide the disadvantages of base lubricants. The best motor substances are oils: Shell Helix, Mobil 1, Castrol, Liquid Moli. According to many experts, goods manufactured by Total and Zeke have not the worst properties, however, when choosing, it is extremely important to take into account the quality of lubricants.

When choosing, the motorist must take into account the lubricating qualities of the fluid, the temperature range of operation, the ability of the substance to function for a long time without losing its primary properties, hygroscopicity, polarity, and the level of evaporation. It is not for nothing that there is an unspoken struggle for supremacy between the leading companies for the production of motor fluids, each plant is trying to invent such a fluid that would have optimal performance in relation to all existing qualities. However, it is not yet possible to isolate only one single substance.

The product in question is purchased by the owners of both injection and, cars are equipped with both automatic transmissions and mechanics. Due to the mass of differences between the types of engines and gearboxes, it is not possible to single out only one single tool, the optimal lubricant should also be bought depending on in which region or climatic zone the car is operated. Besides, important indicator for many, the price of the finished product becomes.

When thinking about which oil is better - Shell or Mobil, it should be borne in mind that Exxon Mobil is one of the leading manufacturers of auto chemicals, widely recognized by car owners from around the world. The most popular are the regularly developed synthetic lubricants. When comparing Shell and Mobile oils, you will need to take into account the fact that Royal Dutch Shell has a strong backbone, owning many subsidiaries of energy and oil refineries. Synthetic and semi-synthetic motor fluids with traditionally high quality are almost always at the peak of fame.

Many motorists often cannot figure out which oil is better - Mobil or Castrol. As practice shows, the product of the Castrol lubricant manufacturer is in great demand among compatriots. Russians are trying to acquire Castrol synthetic and semi-synthetic substances that are ideal for powertrains installed on both passenger cars and trucks, on motorcycles. Analysis of chemical properties car oils of these manufacturers does not allow us to name only one unprecedented winner. All the lubricants described by these companies are in demand among Russian motorists. Due to the constantly growing competition, lubricant manufacturing companies are regularly looking for new technologies, improving the quality indicators of their products.

The principle of choosing a motor lubricant

Comparing Mobil and Shell oils, we can conclude that both lubricants have excellent quality indicators, which made them immensely popular among motorists from all over the world. True, Castrol oil also has not the worst qualities.

Before buying this or that lubricant, you need to pay attention to the climatic conditions in which the car will be operated. With the active operation of the vehicle at the time of combustion, any fuel is converted into carbon deposits. Any residual deposits do not disappear without leaving a trace, they remain on the walls of the motor elements. The essence of the work of lubricants is to significantly reduce friction between engine parts, neutralize oxidation reactions, wash off harmful deposits from system elements, which necessitates periodically changing engine oil.

When buying a lubricant, you should consider its environmental friendliness and safety. With regard to the season, you should choose a summer, winter or all-season liquid. There are always engine oils on sale that are designed exclusively for a specific type of engine, as well as universal ones. Of course, if there is a sufficient amount, it is recommended to give preference to Shell or Mobile oils (if they are original) or cheaper analogues produced by Total, Lukoil, TNK factories.

The main differences between oils

To understand which oil is better - Mobile or Castrol, you should check it against many factors. According to different criteria, the leaders are completely different lubricants. When considering the factor of the most economical fuel consumption, the Shell product leads. According to research, people who prefer this brand of goods can save about 8% on the fuel they use.

Often comparative analysis affects the stability of the oil film, motorists are often interested in comparing lubricants at low temperatures. Here, the unprecedented leader is the product of the Mobil company. Such a lubricant increases the service life of the engine, as it has a beneficial effect on reducing the wear of system elements. True, this negatively affects the power of the power unit, due to the increased coefficient of friction that appears due to the formed film. Shell and Castrol greases have these qualities somewhat less pronounced.

Russian experts regularly check motor lubricants in many ways. For example, with respect to kinematic and dynamic viscosity, all oils have excellent performance. When it comes to additives, lubricants win Mobil companies, Shell, Castrol (at the same level of oils from Zik and Total). In terms of density, all oils correspond to the stated indicators. If we talk exclusively about antiwear properties, it is worth giving preference to Mobil and Shell greases, Castrol is a little weaker in this regard.

Taking into account the waste consumption and all the above criteria, Russian experts note that all the above-mentioned companies supply oil to the market, on which a motorist can drive about 300 thousand km without unnecessary problems. Test results have shown that Shell, Castrol and Mobile greases are suitable for use under normal operating conditions. Only with heavy loads on the power unit of the machine or high temperatures you should pay attention to the properties of a particular substance.

Conclusion

So, it is impossible to single out only one oil that would have excellent characteristics in all respects. The optimal substance should be chosen according to the temperature and load conditions in power unit... Some specific features of the vehicle should also be taken into account, sometimes the use of a high-quality fluid is impossible due to a certain amount of clearance in the details, which directly affects the efficiency of the fluid. You should purchase only the product that meets the technical definitions of the manufacturer, as well as the personal preferences of the motorist. The main thing is that the working substance must be original, not fake.
