Engine oil is not only one of the most important and indispensable components of our vehicles but, in some ways, also one of the most complex to deal with, especially in everyday life.
Many people think, evidently wrongly, that the oil change not only be a child’s play, but that whatever choice can be made is correct: but it’s the exact opposite.
Engine oils they are never the sameand in fact there are many to confirm this acronymsfundamental and identifying, that perhaps most of us doesn’t even understand.
Acronyms which, in fact, not only distinguish one engine oil from another, but which also tell us which is the right one for that single car: so that one should be used and not others.
Impossible to think of you can buy any one: even logic dictates it, but even more so it is everyday practice that suggests it to us, if we really don’t want to damage the machine.
Engine oil: the acronyms that no one knows, but they are crucial
As mentioned, there is not a good engine oil for every car, but a lubricant that is suitable for the car and which is reported in the maintenance manuals. What matters is not the brand of the oil, but rather acronyms. In particular those relating to viscosity. In practice they indicate and measure the thickness in terms of density and fluidity of the oil in relation to given temperatures: the classification is indicated with the acronym SAE accompanied by numbers and the letter W to indicate ‘winter’winter.
They are called monodegree the oil gives a single performance, hot or cold, and instead multigrade those that give optimal functionality at both low and high temperature levels: they are part of the first group of various SAE 5W30, SAE 10W40, for example, or even SAE 15W50.

Engine oil, what do the letters A, B and C mean
Then there are the specifications API, or American petroleum Institute, which regulate three bands of oils grouped with two-letter acronyms: the first indicates use, the second quality. For example the type A is for petrol, while B is for diesel and C and for the modern ones with anti filter particulate matterthe famous DPFwith two-stroke engines.
Engine oil can be of type MINERALbut also synthetic o semi Synthetic: Synthetics use additives to increase the oil’s resistance to heat excessive. In this sense, you should never mix oils of different types to avoid risking serious damage.
