RIGHT ENGINE OIL FOR CARS AND MOTORBIKES: HOW TO CHOOSE IT

WHAT IS ENGINE OIL MADE OF?

The different types of  engine lubricants  consist of:

  • Base oil (solvent with lubricating properties inside which the additives are dissolved) can be of mineral origin, deriving from the distillation of petroleum, synthetic, deriving from industrial chemical synthesis processes or from the strong treatment of products derived from the distillation of oil , regenerated, derives from the industrial treatment of waste oils.
  • Additive packages, a set of chemicals necessary to give lubricant performance and determine its specifications (API, ACEA, Builders, etc.).
  • Improvers of rheological characteristics, they are substances that act on the lubricant flow characteristics, allowing a good fluidity at low temperature (facilitating the cold engine starting) and at the same time a suitable high temperature viscosity (fundamental requirement for an effective lubrication and protection of the engine in operation). These substances are generally polymers capable of increasing the viscosity index so as to counteract the effect of the decrease in viscosity with increasing temperature. Other substances such as the pour point improvers, are able to allow the oil to flow at low temperature, inhibiting freezing.

The elements listed above make up the finished engine oil, but do not certify its quality.
In order to obtain a high quality engine oil it will be necessary to know how to choose the best quality elements and mix them in the specific doses in relation to the use to which the oil is destined.

WHAT ARE THE ADDITIVES USED IN MOTOR OILS FOR?

  • Make engine oil suitable for specific applications
  • They act on the destructive processes caused by combustion, rust / corrosion, deposits / dirt
  • Extend the life of the lubricant by counteracting degradation processes such as contamination, acidification, thermal oxidation, soot / sludge contamination
  • They improve specific physical properties of motor oil such as anti-foaming properties and pour point

WHAT IS THE VISCOSITY OF AN ENGINE OIL?

Viscosity is one of the most important characteristics for a  car  or motorcycle engine oil :

  • the viscosity of a fluid measures its resistance to sliding, and represents its internal friction;
  • the viscosity changes with the variation of temperature and pressure;

HOW TO CHOOSE CAR ENGINE OIL, DIESEL OR PETROL TYPES

How to choose car engine oil types , be it diesel or gasoline? Knowing how to choose the car’s engine oil is always an important decision. There are so many types of engine oil, apparently all such similar lubricants, different abbreviations and seemingly inexplicable cost differences. A wrong choice, however, can compromise your engine.

Proper maintenance of car oil is vital for the life and correct operation of each car. Then what engine oil to use: how to navigate the engine oil classification? For example, what happens when choosing an economical engine oil? The brands of engine oil are important. Do not be too attracted by the price: if you see a lubricant of an unknown brand at an extremely low price at the supermarket, be wary of it. The quality, unfortunately, you pay. And it would be foolish to save, risking to compromise the whole engine of your car: with the wrong engine oil the damages can reach thousands of euros. It is also good to remember that the oil level must be checked regularly, it is not enough to avoid having a degraded engine oil. There are engines and engines, some do not even eat a drop of oil between one coupon and another, others do. This is why it is useful to keep an eye on the level during the time.

When to change engine oil? The correct regularity is fundamental, because the engine oil is consumed and degraded. The petrol engine oil should normally be replaced in a range between 10,000 and 20,000 km, mileage indicated in the vehicle use and maintenance manual. For the oil of a diesel engine, however, these figures reach up to values ​​of 30 / 35,000 km, even if on the engines of the latest generation the range of coupons has been reduced a lot (even to 15,000 km).

Common sense, however, says that it is better if these mileage intervals are anticipated, because it can only do well with the engine. In addition, keep in mind that the prescriptions of the houses provide for maintenance at fixed intervals, in years or kilometers (which of the two requirements takes place first). So even if you go a long way, it’s important that you replace the lubricant often.
