A mistake made when choosing an automobile oil can lead to very unpleasant consequences. In the best case, the fuel and oil consumption will increase and the engine power will decrease. In the worst case, the life of the engine will be significantly reduced.
Instructions
Step 1
First of all, find out what kind of oil the engine manufacturer of your car recommends to fill. Please note that we are talking about the engine and not about the car brand. As a rule, all the requirements for engine oil are described in the service book, however, if you do not have one, then you can find out all the information you are interested in on the manufacturer's official website. Do not trust the forums and advice of your comrades! Use only official data.
Step 2
Think about whether you are satisfied with the oil that is filled at the moment. The fact is that it is absolutely impossible to mix different oils, so if you choose a different brand, then first you will have to thoroughly flush the engine. To determine whether to change the oil, pay attention to its consumption. If it significantly exceeds the rate specified by the engine manufacturer, then the oil is really time to change.
Step 3
List the brands of engine oils that are recommended by your car's engine manufacturer. Sales consultants in specialized stores often try to sell more expensive oil, claiming that the list is far from complete, and that this particular product is the best fit for the engine of your car, although its manufacturer does not know about it. Don't fall for provocations. It is also important to remember that some manufacturers of automotive oils indicate almost all brands of cars on the labels, without specifying which engine the oil is suitable for. Pay attention only to the oil tolerances and their compliance with the tolerances recommended by the engine manufacturer.
Step 4
Select the oil with the most suitable viscosity. If the viscosity of the oil previously poured into the engine suits you, then it is enough to buy the same oil as last time. If the consumption exceeds the rate indicated by the manufacturer, then the viscosity should be increased. Generally, the older the engine and the higher the mileage, the higher the viscosity should be. But remember that in any case it should not exceed the permissible value.
