Comparison MOBIL Advanced Full Synthetic 0W-40 4 L vs MOBIL New Life 5W-30 1 L

The nominal capacity of the package, in other words, the volume of oil supplied in this packaging option.

Depending on the purpose of the purchase, the type of vehicle and other factors, the optimal volume will be different. So, liter bottles are useful for replenishing the oil supply, or for tasks that do not require high consumption (for example, infrequent work with a gas tool); a capacity of 4 liters is designed for a complete oil change in a passenger car; the volumes required by trucks can reach tens of liters; and for car parks, service stations and other similar organizations, oil is produced in barrels of about 200 liters.

The degree of oil viscosity, determined according to the international SAE standard. Viscosity is one of the key physical characteristics of an oil that determines its compatibility with a particular engine. Most modern brands of oil are all-weather and are designed for use, incl. and at low temperatures. Therefore, the SAE index for them includes information not only on the viscosity characteristics in a warm engine, but also on frost resistance.

Such an index is usually written in the form of two digits separated by the letter w: 0w-8, 0w-12, 0w-15, 0w-16, 0w-20, 0w-30, 0w-40, 0w-50, 5w-20, 5w -30, 5w-40, 5w-50, 5w-60, 10w-30, 10w-40, 10w-50, 10w-60, 15w-40, 15w-50, 15w-60, 20w-20, 20w-50, 20w-60,...25w-40. There is also the format SAE 10w, SAE 20, SAE 30, SAE 40 and SAE 50. The first number describes only the cold resistance of the oil, and does not apply to its properties when the engine is warm. If 35 is subtracted from this number, you get the minimum temperature at which the engine can be cranked over to start. In our example, this temperature will be 15-35=-20 °C. Of course, such values are rather arbitrary, because In practice, other factors must also be taken into account. For example, with a “dead” battery (which is not uncommon in cold weather), a cold start can cause difficulties even at a higher temperature than follows from the characteristics of the oil.

The second number determines the characteristics of the oil in a warm engine in normal mode, at normal operating temperatures. It is this indicator that is the main one for choosing a brand of lubricant for a particular car - you must strictly adhere to the manufacturer's recommendations. The fact is that each engine is designed based on strictly defined viscosity values. An oil that is too viscous will linger in large quantities in moving parts, and one that is too fluid will leave them without lubrication at all; In both cases, power drops and wear increases. Therefore, first of all, when choosing according to SAE, the second number and its correspondence to the characteristics of the engine should be taken into account.

Tolerance can be described as an individual automaker's own standard, developed for a specific engine or engine line. It includes all the requirements that an oil must meet in order to be optimally suited for a particular engine. The list of these requirements is much wider than in generally accepted standards (see above). This is due to the fact that many of the manufacturer's developments applied in the motor and affecting the requirements for oil are still too specific and cannot be included in the general rules (and some cannot be taken into account also because they are classified information) . Many famous car brands have their approvals ( BMW, Fiat, Ford, MAN, Mercedes-Benz, Opel, Renault, Peugeot and Citroen, Volvo and VW concern); to obtain approval, each brand of oil undergoes very rigorous tests, and only after them does it receive the right to indicate information on compliance on the packaging.

This information, of course, is not necessarily indicated for all car models. However, if the tolerance data is in the official specifications of your car, the search for the right brand of oil is greatly simplified — the complia...nce of the oil with this tolerance automatically guarantees optimal compatibility with the car. In other words, instead of specifying a whole set of parameters (appointment, viscosity, etc.), it will be enough to make sure that there is a tolerance.
