FAQ

Firstly, if you always use motor oil of low quality engine will radically be clogged by adjournments that are formed as a result of carbon deposits. This also entails increasing of fuel consumption.

Secondly, capital repairs of engine may require in the further. If the vehicle works with a high level carbon deposits in the engine for a long time, the motor does not washed by changing the motor oil.

 The consequence of regular use of low-quality motor oil is on the photo (black carbon deposits on the internal walls of combustion engine)

Motor oil is moving in a closed circle. The oil pump draws oil from the engine’ crankcase, runs through the channels, greasing engine parts, getting rid of waste, and surpluses again settle into the crankcase. Thus, motor oil is continuously circulated throughout the system, and therefore motor oil will get dark in the process.

Engine oil should get dark, because one of the functions of motor oil is the engine’ cleaning from any kind of impurities, corrosive elements and the combustion products. That is why there is a darkening of the motor oil. Motor oil must have good detergent properties for a correct working of engine’ cleaning/

But if the motor oil get dark so quick or becomes blacks, you must by consulted by service station.

You need to change the motor oil, because during engine working lubricants lose their functions of effectively and reliably protect the engine. After it wear of engine parts begins. For vehicles with high mileage (which is important for the UAE, because the mileage is growing so fast) or old vehicles it is particularly important to change high quality motor oil, because avoiding wear of engine parts is impossible, but extending the life of the motor is real by frequent changes of high-quality oil.

The high price of motor oil does not guarantee the high quality, but generally cheap motor oil are made from oil of secondary processing, that it could adversely affect to the engine working of your car in the future. Motor oil may be inexpensive, but the most important thing is quality at this price. Therefore, you should remember, that the main criterion in choosing of motor oil is first of all the quality of the production (not price – cheap or expensive). The role of motor oil in engine working cannot be underestimated, because the main problems that arise in the engine working, are occur owing to poor-quality engine oil.

Brand FOSSER offers inexpensive affordable prices, as named brand of motor oils, which are represented on the market. In addition, we regularly organize actions, about which you can be found on our website or in social networks. It should be remembered that the price-quality ratio is an important factor in buying motor oil, according to the estimates of the German specialists, 75% of the main problems that arise in the engine working, occur owing to the lubricants.

Therefore, considering the importance of motor oil in the engine working of your car, shound not save money on quality engine oil (oil significantly reduces friction and wear of moving parts, ensures cleaning of engine parts, improves the leakproofness, cool the engine and prevent corrosion). For vehicles with high mileage (that is important for the UAE, because the mileage is growing sufficiently fast here) it is particularly important to change high quality motor oil, because avoiding wear of engine parts is impossible, but extending the life of the motor is real by frequent changes of high-quality oil. In addition, it is so important to care about protecting your car engine from the beginning of acquisition.

Uninterrupted and clear working process ensures automated production.

Daily production capacity of is up to 100,000 containers with a volume of 250 ml to 1,000 liters. Currently, the reserve capacity of finished products contains more than 6.1 million liters. Warehouses, equipped with the modern gravitational roller system of racks and handling equipment amounts to 35,000 square meters (it contains more 5 million liters). New robotic packaging line installed for the past two years allows producing motor oil in containers with a high degree of protection against forgery. Modern dark blue patented canister (shape and color of which no one has the right to copy) has a six-color waterproof label. The canister is protected by a hologram and a telescopic cover which simultaneously provides both tightness and a function of the funnel, which is so convenient during filling of oil.

The matter density is equal to its mass-volume relation (kg per m³); as to the lube oils, it is measured in at the temperatures of +15° С or +20° С. Such characteristic is important in case the great lots of oil products are purchased, because at different temperatures the density changes, and the same tank filed at the temperatures of +5° С or +35° С will contain different amounts of product. The difference can be calculated with a well known formula. As to the “ordinary user” it is enough to know that the bulked oil products shall be purchased in the cold weather (seasons), and at higher pressure the oil pressure increases. The relative density is equal to the relation of mass of the defiite volume of agent to the mass of the respective volume of water at the temperature of 20° С. The density and relative density depend on the temperature.

The viscosity is one of the most important characteristics of the lube oil. It characterizes the internal friction and determines the flow property and capacity to ensure the hydrodynamic conditions of lubrication. The viscosity depends on temperature: within the temperature interval (usually from – 30° С to +150° С) the viscosity of mineral (petroleum) oils can vary considerably (several thousand times). There are two kind of viscosity: cinematic and dynamic (absolute) viscosity. The fist one is common for simple lube oils used at positive temperatures, and it is measured with the capillary viscosimeters; the second one is common for solidifid (all-season) oils and oils used at negative temperatures, and it is measured with the rotational viscosimeters, because its value depends not only on the temperature, but also on the share rate gradient. The cinematic viscosity is measured in Stokes (St) or centistokes (cSt) (Engineer’s System of Units), and in m2/s or mm2/s (SI unit). The dynamic viscosity is equal to cinematic viscosity multiplied by the flid density; it is measured in centipoises (cP) (Engineer’s System of Units) and in milliPascal-second (mPa-s) (SI Unit), where 1 cP = 1mPa-s).

The viscosity index (VI) is a dimensionless index characterizing the dependence of the lube oil viscosity on the temperature change. Higher is the viscosity index, less the lube oil viscosity changes at variable temperatures. It depends on the hydrocarbon composition of the lube oil, availability of solidifying (viscosity) additives, effiiency of the lube fractions cleaning. The viscosity index of mineral lube oils without solidifying additives is from 85 to 100, and the lube oils with solidifying additives and synthetic oils can have the viscosity index from 120 to 150.

The viscosity index of thin lube oils can reach 200. The flsh point. When the temperature rises, the lube oils emit vapors which flash being in contact with open fie. Such temperature is flash temperature, which can be measured in an open (Cleveland) or closed (Pensky-Martens) crucible. Such index shows the availability of boiling fractions in the lube oil and is connected with the lube oil vaporability during its use. Some values of flsh points are shown below: from – 30° С to – 40° С and lower: for the low-boiling hydrocarbons and petrol; from + 28° С to +60° С: for kerosene fractions; from + 13° С to + 325° С:for lube fractions.

The setting point is the lowest temperature, at which the lube oil does not lose its flidity being cooled in the test tube. The setting point characterizes the moment, when the viscosity increases dramatically at low temperature; at the same time, the paraffi crystallizes, and the lube oil hardens. During the service, the lube oils accumulate the acidic and or alkaline products generated as result of oxidation, disintegration of molecules of the basic oil and additives, oils contamination, including accumulation of the combustion products and carbon black.

The total alkali neutralization number /total base number (TBN) and total acid number (TAN) are analyzed in the laboratory environment. The TBN is expressed by the quantity of potassium hydroxide in milligrams equivalent to the quantity of all alkali components contained in 1 gram of oil (mg KOH/g). The TAN is expressed by the quantity of potassium hydroxide in milligrams necessary to neutralize the acidic products contained in 1 gram of oil (mg KOH/g).

The dropping (melting) point is a conditional test showing the temperature, at which the plastic lubricant melting begins, i.e. the temperature, at which the fist droplet of lubricant falls, the lubricant being warmed in the capsule of Ubellode thermometer (method ASTM D 566- IP/32; DIN 5/80/B1.1; ISO 2/76). The dropping temperature shall be 10 – 20° C higher than the heating temperature of the unit/block, where such lubricant is used.
