The main differences between motor oils for different types of engines  

Since petrol and diesel engines have different principles of operation and, accordingly, are powered by different fuels, it does not seem strange that the effective work they also need different oil. Inexperienced drivers can easily confuse Xenum oil with engine oil designed for diesel engine. As a result, this leads to a malfunction of the power unit, which should be avoided if there is a desire to extend his life. To avoid such confusion occurred, it is necessary to explain what is the main difference between the two types of oils.
category API

Motor oil for diesel engines of passenger cars should relate to the class ACEA B and API to certain categories, but for the new diesel engines of high power - to the SHPD class (ACEA E class). Each class diesel engine oil designed for a certain capacity, so this option it is necessary to pay attention.
What is the difference?

To understand why we can not confuse the oil for gasoline engines with oil for a diesel engine, it is worth to know how they differ:

    Different resistance to oxidation and to shear deformation at high operating temperatures;
    different alkalinity reserve which is needed to neutralize the acid formed during combustion.

These are two major differences are the basis of producing oils with different chemical compositions and with different technical features. The main differences between the manufacturers and indicated in the certificate of factory production, which are also worth exploring to choose the ideal specifications for a particular engine oil type and capacity.
