The range of use in the car market of both engine and transmission oils is extremely wide. Our website contains an overview of the most popular brands of oils, their technical characteristics, features, advantages and disadvantages.
General recommendations for the selection of oils are as follows: compliance with climatic conditions and temperature parameters of vehicle operation, the type of engine, the degree of wear, the car brand and its documents, the manufacturer’s service book, which indicates the specific type of oil to be filled.
For the convenience of characterizing the technical qualities of oils, there is a special marking system that classifies oils by various indicators.
Every car owner wants to use high-quality oil at an affordable price, which has good protective properties, viscosity and replacement interval. The oil viscosity changes depending on the operating temperature conditions. The site will consider all possible options for using common types of lubricants.
Let’s consider the labeling of the name of one of the trade varieties of synthetic oil Eni i-sint 5w40 .
5w 40 – the viscosity of this product, where 5 is the minimum temperature indicator (not the temperature itself! )use in winter conditions. To determine the actual ambient temperature at which it is possible to start the engine, you need to subtract 35 degrees Celsius from 5, that is, minus 30 degrees Celsius. The letter w indicates the suitability of the oil for use in negative (winter) temperatures. The figure 40 very approximately indicates the limit of the plus temperature at which it is possible to operate the engine in hot conditions. Thus, Eni i-sint 5w40 is a standard type of all-season synthetic oil.
