Synthetic or semi-synthetic oil Liquid Moli 5w40, due to its high technical characteristics and low price, is in great demand among domestic motorists.

Semi synthetic oil Liquid Moli 5w40 is suitable for used cars of both European and Japanese production. For vehicles running on diesel fuel Liqui Moly 5w40 would also be a great solution.

It is known that the condition for the successful operation of the engine is the use of high-quality lubrication. According to the results of the ratings, 3rd place in the TOP-5 best oils LIQWI MOLY corporation lubricating fluids are regularly occupied. The article will discuss the oils of this company, belonging to the 5W-40 viscosity group.

Features of Liqui Moly oils

The products of the German company are known far beyond the borders of Germany. Impeccable quality, thoughtful package design with a strong logo and a rich pedigree provide the brand with a well-deserved reputation. Liqui Moly oil is poured into the engines of their cars by drivers in more than a hundred countries around the world.

Below is a description of the 3 main brands of Liqui moly viscosity group 5w40.

HC-synthetic engine oil Optimal Synth 5W-40

As the name suggests, the lubricant is produced using hydrocracking (HC-synthesis) technology. Often such compositions are undeservedly called "semi-synthetics". In fact, they are completely synthetic. Basic components and technological methods ensure that the highest requirements of modern internal combustion engines are met.

Optimal Synth guarantees reliable lubrication under all conditions, while lighter friction reduces fuel consumption. Application of the product in question:

• facilitates the supply of lubricant to rubbing parts at the time of winter start-up;
• reduces lubricant consumption;
• ensures maximum cleanliness of the engine compartment;
• has minimal effect on the neutralizer;
• recommended for units equipped with turbocharging.

This engine oil is Optimal-but combines affordable price and traditional German quality.

Synthoil High Tech Synthetic Motor Oil 5W-40

This fully synthetic low viscosity product is based on polyalphaoleins (PAO) and is designed for all season use in modern internal combustion engines. Scope: highly loaded engines, and units equipped with a turbocharger or intercooler are no exception.

It is widely used on tuned and sports cars. Synthoil lubricants not only improve friction but also prevent deposits. 100% synthetic 5W-40 provides:

• excellent performance at low temperatures;
• resistance to thermal-oxidative processes and aging;
• motor protection against wear in a wide temperature range;
• "livability" with a turbocharger and catalysts of all types;
• reduction in lubricant consumption;

• maintaining the cleanliness of the power unit.

All these characteristics allow you to be sure of the protective properties of Synthoil lubricant even with significant temperature changes, refueling with low-quality fuel or untimely replacement lubricant.

The next generation of HC synthetics

The full name of the product is Molygen New Generation 5W-40 HC-synthetic engine oil. The new line has been used innovative technology Molecular Friction Control (MFC). Briefly, its essence can be explained by the fact that another chemical element, tungsten (anti-seize additive Molygen NG), is added to the composition of antifriction additives, which usually include molybdenum.

Its presence modifies rubbing surfaces, smoothes them, and the result accompanying the use of such an oil appears already 30 minutes after its filling. What are the external manifestations of the engine with new generation Liquid Moli 5w40 oil:

• engine traction improves;
• saves fuel up to 3.5 - 5%;
• oil consumption is reduced by 25 - 30%;
• its heating is reduced, which reduces the amount of varnish deposits;
• the amount of harmful emissions, including sulfur and phosphorus, is reduced;
• clean engine, which is explained by the absence of oil combustion products.

The new liquid is painted in an unusual green color.

Was costet das?

The table shows the average cost of the above motor oils.

As you can see, in Russia, the German oil of Likvi Moli can hardly be called "folk oil". The circle of his admirers are mainly owners of sports cars and premium cars.

German corporation that manufactures motor Liqui Moly oils, has long been known on the market, the Liquid Moli 5w40 synthetic product line, reviews of the oils included in it, and their characteristics will be the main topic of the review.

Reviews of Liquid Moli 5w40

Of course, only car owners can give an assessment of any engine oil. Their opinion about this product they left the following:

№	User Reviews
1	The oil is of high quality, I don’t argue, but I ran into counterfeit products several times and almost ruined the engine. The price is high, they don’t reduce it for fakes, so you can find something simpler for such money with the same indicators. It turned out that almost all Rosneft does not have detergent additives in their oils, so lubrication is frequent, there is no soot, and all the waste junk remains inside the motor, covering it evenly. If you need such a pleasure, to play with flushes, additional additives and other banks, then buy Rosneft semi-synthetics, and I think synthetics are the same. especially before inspection. The person is familiar, so he does not say too much. So. He constantly cursed at my oil, then soot, then soot, then topping up. Until I switched to G Energy 10w40, I constantly heard from him that I was a blonde. Now for the second year I am in the rank of a pro. He is overjoyed at the car and does not touch me. I recommend this oil to everyone, especially to women who always take the word of machine pros. Choose from this line and enjoy. Unpleasant chores will be left behind. I recommend to everyone.
2	Excellent oil Liquid Moli 5w40 and worth it. It really saves fuel, the engine runs quietly, there are no top-ups, very low waste, at -35 the car starts easily from one revolution, the engine is grateful, I am grateful, I recommend it to everyone.
3	I join the professionals, oil can be used in almost all engines without thinking. The quality is excellent, all the declared characteristics of the manufacturer, surpass themselves in work. I've been with Molly for 4 years now and I'm not going to change. Expensive - I do not argue, but motor repair is clearly more expensive. I dashed off 20,000 km on it and only then replaced it, I didn’t see much difference after 15,000. So, buy the product and enjoy.

Increased demand from car owners and positive reviews Liqui Moly 5W-40 speaks for itself. The content of the necessary additives in the required amount in Liqui Moli synthetics makes the engine quiet and easy to start, even in harsh winters. The only thing that does not suit and repel buyers is its high price.

The German chemical concern Liqui Moly started its activity 60 years ago with just one product: a protective additive based on molybdenum dioxide.

It was special fluid, which, thanks to molybdenum molecules, protected engine parts during oil starvation. Actually, even the name of the enterprise is translated as "molybdenum liquid".

Developing this theme, engineers introduced new technical consumables containing the same additive. As a result, any Liquid Moli 5W40 engine oils, or other viscosity, necessarily contain molybdenum.

This does not mean that all compositions are the same: German concern offers a whole series of products with unique properties and applicability to different types motors.

What unites the Liquid Molly 5W 40 oil line?

First of all, viscosity indicators according to SAE.


The letter W means that lubricant belongs to the winter class. This does not mean that in the warm season it is necessary to change the oil.

But at low temperatures, the main physical properties are provided, on which the "health" of the motor depends:

• cranking cardan shaft without extra effort at low temperature: -25°C;
• the pumpability of Liquid Moli 5W40 motor oil through the oil pipeline channels does not deteriorate up to a temperature of -35 ° C. Range of applicability without loss of basic parameters guaranteed from -25°C to +35°C
• Next feature: all Liquid Moli 5w40 oils are produced with molybdenum.

Molybdenum disulfide additive is a highly effective friction modifier. Evenly distributed over the working surface of the metal, it creates a layer that reduces the load on the parts when they come into contact.

This reduces wear and mechanical costs to overcome resistance.

What is the secret of the molybdenum additive in Liquid Molly 5W40 oil?

Molybdenum disulfide is a powder that is insoluble in liquids. If it is added to oil, it will be in a state of suspension.

The molybdenum additive smooths out irregularities, giving the oil the opportunity to fully realize its anti-friction properties.


As a result, the contact point of the rubbing parts is separated by a protective layer. The temperature of the parts is reduced, scuffing is prevented.

Another unifying factor is compatibility with the engines of most car models. Almost all manufacturers of vehicles on wheels, after rigorous testing, have issued Liqui Moly oils with approvals and certificates.

Any Liquid Moli 5W40 oil is synthetic. However, for a demanding consumer, you should know the nuances. Concern Liqui Moly produces two types basic foundation, which modern classification SAE may be referred to as synthetic:

1. Universal processing method based on hydrocracking synthesis technology (HC). If you do not pay attention to a single standard created by marketers, this is a common mineral oil high degree of purification. But the technology is so perfect that the quality of the HC base practically does not differ from the 100% synthesis product. This is confirmed by reviews of HC oil Liquid Moli 5W40.
2. 100% synthetic base based on polyalphaolefins (PAO). This oil is synthesized from natural gas, while the molecular lattice is programmed by developers in accordance with terms of reference. That is, the properties of the product are set at the stage of creating the foundation, and the additives simply bring the engine oil Liquid Moli 5W40 to perfection.

Liquid Moli 5W40 synthetic oil - reviews

Customer reviews also combine a line of oils with molybdenum. Almost everyone notes an improvement in the condition of the engine.

Of course, the main characteristics do not change, but the following advantages, which are not determined in laboratories, can be listed:

• the operation of the motor becomes quieter, there are no sharp sounds;
• reduction of mechanical losses leads to improved efficiency;
• there are no jerks when starting and stopping the engine, this is especially evident in the start-stop mode;
• due to the forming nano-coating, the powder is practically not erased from the metal surface: the oil remains relatively transparent throughout the entire period of application.
