What engine oil is good for

Even the less experienced surely know that every vehicle, to function properly needs, among other things, a good engine oil that constantly lubricates every mechanism of it. The oil flows through each component bringing the right lubrication and thus: reducing friction, cooling the parts subject to overheating, and cleaning the mechanisms.

To this day, automobiles are in step with the times and have followed the evolution with continuous improvements in materials, which is why if until the 1950s, an engine over 80,000 kilometers was considered to be ”rebuilt” completely, today it still has much to give. This has been achieved not only by choosing quality materials but also by improving lubricants, let’s see in this article the importance of the main one for the long life of the car: engine oil.

Changing the oil

Frequent oil changes will ensure a long life for your car by preventing malfunctions due to components that jam because they don’t flow well with each other. There is no standard mileage for doing this some vehicles require about 10,000 km, we are talking about those powered by gasoline which, in new models can go up to 15,000. If we are talking about diesel engines, the oil change is necessary every about 25,000 km.

The figure is reported on a special plate in the vehicle registration, in any case, it is important to rely only on specialized mechanical workshops because this operation is not simple, it is very delicate and must be carried out by competent personnel, as well as equipped with the right equipment and permission to proceed to the proper disposal of the spent substance.

Check the level

What you can do instead on your own is to check the oil level. This is a fairly simple operation when you open the hood you will notice that the oil tank contains the so-called ”stick,” which is the dipstick that will help you figure out how much oil you have. The oil check can be done at any time, you just need to follow a few steps:

park the car on level ground so that the slope of the ground does not affect the slope of the liquid inside the tank to give incorrect data,
the car must be off and with the hand brake on,
for the level to stabilize, the car must have the engine sufficiently cold,
wear protective gloves,
pull out the dipstick, which is easily recognizable because of its looped end,
wipe it clean with a cloth,
insert it again,
pull it out after a few seconds to check the actual oil level.
To get a good amount, you have to take as a reference the two notches on the end of the rod, which indicate the maximum and minimum limits.

If refilling is necessary, it will be sufficient to remove the cap and add the missing oil through a small funnel. After waiting a few seconds the check is made again, after which the cap is closed tightly and the operation is completed.

Why oil change is important

Checking the oil level can be done on your own or at a workshop, in any case, you will notice that sometimes the liquid is thicker and darker, this indicates that it is time to change the oil and not simply top it up as needed. It’s a different story for the complete change, which unlike topping up requires the mandatory intervention of a professional who will know how to choose the most suitable and performing oil according to the type of car, as well as operate safely respecting the mechanical parts of the car and lawfully disposing of waste products.

Relying on competent personnel also has the purpose of being sure that you are adopting a quality lubricant, capable of keeping the powertrain and engine running well and for a long time, while also avoiding breakdowns and economic damage. The function of engine oil is precisely to preserve for as long as possible each mechanical component of the engine, which is inevitably subject to wear and tear and stress.

Thanks to such a lubricant everything will always be clean and protected from corrosion. On the contrary, failure to change the oil periodically after the recommended mileage leads to unpleasant consequences that not only result in less pre-performing engines but are also subject to failure and increased wear due to friction and overheating.

Main characteristics of engine oil

Engine oil consists of hydrocarbons and additives whose job is to increase the level of viscosity. Several brands are found on the market, but there are three types of oil: mineral for agricultural machinery, synthetic, and semi-synthetic for automobiles. Choosing a reputable brand means relying on professionals who have designed a product with the right density and viscosity, with first-rate additives to support your car’s good performance.

The added additives are an important component because they prevent foaming and oxidation of the oil, which, during its life is subjected to continuous temperature changes produced by the engine. Lubricating oil does a very simple but at the same time necessary job it is pushed inside the engine by a pump, in which it flows under pressure to reach even the most hidden places, including the cylinder walls.


For the reasons listed in the various paragraphs, it is important that the oil never falls below the minimum level and that it is always clean. Going to the workshop periodically and letting a professional advise you is a gesture of love for your car and will ensure it still has a long way ahead of it.
