Liqui Moly 10w40 review
Content
Every driver knows that the quality of engine oil determines how well and how long the car engine will run. The lubricants market is saturated with various products for every taste, among which it is sometimes difficult to navigate and choose a worthy option. Among the leaders stands out the company Liqui Moly, whose products are made in the best traditions of German quality. Let's see why their products are worth buying, using the example of Liquid Moli motor oils with a semi-synthetic specification 10w 40 and take a look at customer reviews.
Product Description
Liqui Moly 10w 40 is a line of semi-synthetic lubricants that fall under the 10w40 category according to the SAE specification. This means that they do not lose their technical characteristics at temperatures from -30 to +40°. This specification has oils from the series:
- Liquid Molly Optimal 10w40;
- Liquid Molly Super Leichtlauf 10w40;
- Liquid Moly MoS2 Leichtlauf 10w40.
Liquid Moli Optimal 10w40 is a semi-synthetic lubricant, in the manufacture of which the technology of deep distillation of oil-based products was used. It has a long service life, high viscosity, and its technical characteristics are not inferior to greases made on the basis of synthetics.
Liqui Moly Super Leichtlauf 10w40 is another representative of semi-synthetics produced by Liqui Moly. The oil has good detergent properties, so that deposits and harmful substances do not settle on the engine walls. Its use increases the life of the engine, due to the reliable protection of parts from wear.
Liqui Moly MoS2 Leichtlauf 10w40 is a semi-synthetic with molybdenum, the addition of which allows you to protect the engine even under high loads. This is achieved due to the fact that molybdenum particles settle on engine parts, and even if the oil film has made a hole, the molybdenum coating will not allow damage to the surface.
Note! Marking 10w40 does not mean that the operating temperature range is limited to -30o and + 40o. It can be increased upwards, but the indicated limits are the minimum threshold that remains in any case.

Important! These characteristics do not change and, if necessary, can be adjusted by the manufacturer within certain limits. Check the manufacturer's website for more details.
Tolerances and specifications
Engine oil approvals indicate that a product meets the requirements of a particular automaker who has tested it in the engines installed in their vehicles.
The products of the German company received approvals for the following brands:
- Volkswagen
- Mercedes Benz
- Renault
- Fiat
- Porsche
The specification indicates the possibility of using it in engines of different generations, the operating temperature range and which additives were used in the production of the lubricant. According to the SAE specification, which assigns a marking based on the operating temperature, Liqui Moly 10w40 means the minimum values \u30b\u40bof -XNUMX ° and +XNUMX.
Form of issue
Knowing the volume of containers in which products are produced will help to avoid fakes that unscrupulous people can sell in other containers. All Liquid Moli products are sold in cans of:
- Minimum volume 1 liter;
- 4 liters;
- 5 liters;
- 20 liters;
- 60 liters;
- 205 liters.
Items sold in other packaging must indicate fraud on the part of the seller. In such a situation, require quality certificates for products or better buy oil elsewhere.
Advantages and disadvantages
Liqui Moly products with a 10w40 specification have the following advantages and disadvantages.
Advantages of Liqui Moly Optimal 10w40
- Increases the life of the car engine.
- Helps save money by extending oil change intervals and saving fuel while the engine is running.
- It is not subject to oxidative processes, so harmful substances do not settle on the engine walls.
- The engine runs normally, without jerks.
Advantages of Liqui Moly Super Leichtlauf 10w40
- The motor starts up easily in severe frost.
- By reducing the friction of engine parts, its service life is increased.
- Well cleans the walls of the engine, removing harmful compounds deposited during operation.
- A universal product that is equally effective on cars with different types of engines.
Advantages of Liqui Moly MoS2 Leichtlauf 10w40
- It is evenly distributed over the working surface of the motor, preventing wear of parts.
- Thanks to molybdenum, the use of MoS2 Leichtlauf 10w40 allows you to create double protection against damage at higher loads.
- Does not lose working capacity either in severe frosts or in heat.
- Equally effective on new and old cars.
All oils have one drawback: they are often counterfeited, like other popular brands. Because of this, buyers who do not know how to distinguish an original from a fake often complain about the quality of the goods, not suspecting that they were simply deceived.
