During the working process, combustion products accumulate in internal combustion engines - soot. It impairs the functioning of individual parts and assemblies, as well as the entire unit as a whole. The friction of rotating elements increases, the performance of the entire system becomes more difficult. The result can be a complete engine shutdown with breakdowns beyond repair. To avoid such problems, oil is poured into the motor, which lubricates all power units, removes carbon deposits and partially cools metal surfaces. In engines with high mileage, these problems are intermittent. The Mobil Oil company took care of these "oldies" and developed a 5W50 motor oil specially for them marked FS x 1.

Oil Description

This lubricant is positioned as synthetic and has high technical parameters inherent in the entire category of these oils. The basic basis was a high-quality composition of oil materials with the addition of innovative detergent additives. Lubrication purposefully cleans the engine from carbon deposits,sludge formation and soot accumulations. Increases the protection of metal surfaces from wear, oxidation processes and prolongs the life cycle of the power unit. A synthetic lubricating product can function in lower sub-zero temperatures than its mineral-based counterparts.

Earlier this brand was called Mobil 1 Peak Life synthetic engine oil 5W50 Mobil, 4l packaging sold. To date, the product is presented in the form of an improved substance with a modern formula of molecular composition. The grease, which has retained all the positive aspects of the previous version, has acquired technical components that meet the progressive requirements of the current generation of lubricants.

Lubrication Features

5W50 oil effectively protects the engine from wear. The oil coating penetrates into all technological areas of the motor, forming a strong film. This is especially important for internal combustion engines, which have worked out more than half of their resource. Metal surfaces already have some wear, and additional protection is vital for them, oil reduces the coefficient of friction, increasing the sliding of parts between themselves. At the same time, the device works without unnecessary resistance and the combustible mixture is saved.

There is an urgent need for cleaning and removing slag from the internal environment of the motor. The detergent and dispersant capabilities of 5W50 oil do an excellent job with this. The products of combustion in the form of soot on the walls of the cylinder block are removed by the lubricating fluid, and the process is prevented.neoplasms. Contaminants are dispersed by the oil, that is, they dissolve in its total mass. During the subsequent regulated change of the oil substance, all waste is removed from the engine along with it. It should be noted that throughout the entire period of operation of the lubricant from replacement to replacement, it does not lose its quality properties, while maintaining a stable viscosity.

Scope of application

5W50 oil has a wide temperature range and can be used in winter cold and summer heat. High thermal stability allows the product to retain its consistency in summer without thinning, and in winter it does not thicken. This is very important when starting the engine in sub-zero weather. Maintained normal viscosity allows starting without much resistance, which affects the wear resistance of parts and fuel economy. This feature is very relevant in the performance of a "worn" engine.

5W50 engine oil is designed to interact with power units using gasoline or diesel fuel as a combustible mixture. But, as mentioned earlier, it is aimed at engines that have worked 100 thousand km or more.

The manufacturer recommends using the oil in European-made cars. The product is approved for use by major automotive concerns such as Porsche, Volkswagen, BMW and Mercedes-Benz.

Technical data

5W50 engine oil specifications includethe following figures:

• all season product fully compliant with SAE 5W50;
• mechanical circulation viscosity at 100℃ test temperature - 17.15mm²/s;
• same parameter at 40 ℃ - 104.50 mm²/s - a bit thick, but within normal limits;
• viscosity index - 180 - quite high, but the oil is also oriented to operation in a wide temperature range;
• presence of a high alkaline level - 11, 79 - provides liquids with excellent detergent and dispersant properties;
• a large amount of filler elements affected the acid number of 3.03 mg KOH/g;
• sulfate ash content within the normal range - 1, 34%;
• oil fire limit - 248 ℃ - very high;
• minus limit of material functioning is 45 ℃.

Additional information

Packaging container for Mobil 5W50 synthetic engine oil - 4 l, 5 l, 20 l, 60 l, 208 l and for topping up 1 l. Each form of release has its own article numbers, which are necessary for accurate product search and accounting.

This grease meets the requirements of the American Petroleum Institute API SN/SM/SL/SJ and CF. According to the Union of European Automobile Manufacturers, the product meets the A3/B3 and A3/B4 specifications.

The oil can withstand severe power overload due to anti-wear modifiers such as molybdenum, the presence of esters and stable viscosity.

Reviews

Like all products"Mobile Oil", this oil has high efficiency parameters and quality performance indicators. This is confirmed by numerous reviews and comments. Regular consumers and professional car owners who own cars with engines that have worked for a considerable number of hours note unsurpassed protection. The lubricant gently cleans the engine without showing aggressive properties, which is important for older engines.

Drivers noticed that for such an oil with a dense consistency, very good low-temperature characteristics. All this, according to the reviews of users of this product, prolongs the life span of their already "tired" faithful "iron horse".

Some car owners poured this lubricant into engines that had passed 30-40 thousand kilometers and were also satisfied with the performance of the oil. The washing properties only decreased, which were compensated by the flushing fluid after each replacement of the oil substance.
