To ensure the proper functioning of your vehicle, you must choose an engine oil that is perfectly adapted to it to lubricate it. In addition to contributing to engine cooling, it also keeps the engine clean and prevents wear and tear on its components. It therefore helps to guarantee the life of the engine. So how to choose the right engine oil for your car? The point.

Consider viscosity indices

The viscosity index is the first element you should consider when choosing the engine oil for your vehicle. If you own a vehicle with a recent engine, choose an oil with a viscosity index of 5w30 or 5w40. This type of oil is also recommended for motorists who tend to put a lot of stress on their cars and heavy rollers. Semi-synthetic oils, with a viscosity index of 10w40, are suitable for mixed routes. Like synthetic oils, they also optimize the cold start of the engine. Mineral oils (15w40) are recommended for older petrol cars or for diesel vehicles without turbocharging. With this oil, a regular auto oil change is essential.

Check the standards

When choosing the right engine oil to maintain your car, it is also important to consider the standards adapted to your vehicle type. To do this, you can seek the advice of a professional or simply rely on your car's manual. The standards on the back of the engine oil cans give you an idea of their performance and give you a clear idea of the type of engine for which they are recommended. These indications also make it possible to know if they comply with recommendations specific to a manufacturer.

Choose the right brand

There are many brands of motor oil and prices vary considerably from one brand to another. Generally, 100% synthetic oils are more expensive than semi-synthetic or mineral oils. In addition to prices, it is also necessary to inquire about the level of additive injected by manufacturers into each engine oil. Oils with a high number of additives are the most expensive.  You are not obliged to turn to any brand or to the one recommended by your car manufacturer. Simply make sure you choose an engine oil that perfectly meets its recommendations to ensure the durability of your engine. If you have any doubts, do not hesitate to seek professional advice.
