Liqui Moly Molygen 5w30 engine oil: review, specifications

Liqui Moly Molygen 5w30 engine oil is positioned by the manufacturer as the best choice for modern Japanese or American-made internal combustion engines. Devices can be multi-valve, equipped with a turbocharging system and an intercooler, as well as without them. The lubricant product guarantees maximum protection and will provide a long-term working life to the most demanding power unit. Lubricant designed for extended drain intervals.

Oil Producer

In the mid-1950s, the Liquid Moli company was founded. At its origins was the German Hans Henle. The company gained fame and popularity thanks to its additive based on molybdenum disulfide. It most effectively protected the rubbing parts from wear.

In the 70s, one of the advertising campaigns carried out amazed the automotive world community. A demonstration was held during which two vehiclesconcern "Volkswagen" rounded the largest lake in Germany without oil in the engine! Instead, only the above additive was filled, which is still used in oils, including Liqui Moly Molygen 5w30.

At the moment, the company produces and produces one of the most successful lines of machine oils that can satisfy any demanding consumer. The range includes all types of lubricants - from mineral to synthetic, with all viscosity classes. They cater to all price ranges. In addition to motor oils, Liquid Moli is engaged in the production of vehicle care products, their repair, and also produces auto chemical goods. Almost all products are developed in-house in close tandem with automotive concerns.

Product Overview

Lubricant Liqui Moly Molygen New Generation 5w30 is a unique product with incredibly effective protective properties. Modern technology, developed in the depths of research by its own talented engineers, is amazing in its possibilities. She introduced chemical compounds of molybdenum and tungsten into the composition of the lubricant. This manufacturing recipe is called Molecular Function Control. The oil film created on this basis has amazing strength parameters.

With such a margin of safety, Liqui Moly Molygen 5w30 lasts much longer than conventional counterparts in this category of lubricants. Almost no oil"leaves", which leads to an increased threshold for changing the spent substance.

The product, thanks to its innovative properties, takes part in the direct saving of the combustible mixture. Sometimes this figure can reach 5%. The oil is responsible for reducing the toxicity of exhaust crankcase gases, has good washing capabilities, cleaning the inner walls of the cylinder block from carbon deposits.

Lubrication Features

Liqui Moly Molygen 5w30 has good pumpability while maintaining a stable viscosity. Lubricating fluid penetrates into all technological gaps of parts and components of the motor, enveloping all metal surfaces as accessible as possible. At the first start of the engine, the structural elements already have oil protection, which provides it with a long service life. During low ambient temperatures, the lubricant does not prevent the free rotation of the crankshaft. It is an important factor in the operation of a power vehicle device, leading to minimization of fuel consumption and increase in wear resistance.

Liqui Moly Molygen New 5w30 automotive lubricant has all the quality characteristics of a synthetic product, but it is a semi-mineral product obtained by hydrocracking.

This synthesis technology involves the deep distillation and refining of crude oil, resulting in a pure base oil. The lubricant is fully consistent with the synthetic counterpart, and to some extent surpasses it.

Use area

Liqui signature oilMoly Molygen 5w30 was designed and manufactured with an eye on gasoline and diesel engines. The units can be optionally equipped with a turbocharger, an additional exhaust filtration system such as particulate filters and catalysts.

This product has undergone numerous tests on Japanese and American vehicle power devices. The manufacturer has issued a regulation on the use of manufactured products for use in such models, but with proper specification, the oil is also suitable for other brands. Approvals and recommendations were issued by the largest automotive concerns: Ford, Honda, Chrysler, KIA, Isuzu, Mazda, Nissan, Toyota and many others.

Lubricant withstands maximum power loads on the engine, up to extreme, with high speeds. Able to give full protection to the motor in slow city traffic, where the operation of the power plant is accompanied by large overheating and frequent stops followed by a start, for example, traffic jams or frequent intersections with traffic lights.

Technical data

Liqui Moly Molygen 5w30 has a distinctive green, slightly phosphorescent color. The technical information is as follows:

  • meets SAE J300 specification and is a full 5w30;
  • Consistency density at 15 ℃ -0.850g/cm³;
  • kinematic coefficient at 40 ℃ - 61.4mm²/s;
  • kinematic coefficient at 100 ℃ - 10.7mm²/s;
  • viscosity index – 166;
  • evapotranspiration, according to the Noack method, - 10, 0%;
  • alkaline indicator – 7.1 mg KOH/g;
  • thermal stability does not exceed 230℃;
  • The freezing point of oil is determined by the minus temperature of 42 ℃.


Many professional drivers speak of this lubricant as a stable and effective means of protection for the motor. Car owners noted the smooth operation of the engine, trouble-free start-up in the winter season. When the used fluid was replaced, the internal parts looked clean, with no visible signs of premature wear of metal surfaces.

There are also negative comments about the insufficient quality of the lubricant due to the fact that it is still inferior to one hundred percent synthetic oils. There are a lot of negative reviews about counterfeit products, very often you can buy not a branded brand, but a handicraft fake that causes irreparable harm to the "heart" of the car.
