Abstract

Abstract
The quality of motor oils for passenger vehicles is defined by international specifications (ACEA-Association des Constructeurs Europeens d'Automobiles, API-American Petroleum Institute, ILSAC-International Lubricant Standardization & Approval Committee) and specifications by the reputable engine/vehicle manufacturers.
One among the goals of introducing ACEA specifications back in 1996 was the joining together of all requirements by European vehicle manufacturers. Sadly, this goal has never been achieved, so that we are now witnessing the appearance of a growing number of specifications by individual vehicle manufacturers.
The number of passenger vehicle motor oil specifications is increasing for two reasons. There are new vehicle manufacturers with motor oil specifications appearing, while those who have already had specifications are increasing their number. The situation is furtherly worsened by the fact that the requirements of individual vehicle manufacturers are mutually inconsistent.
A direct consequence of the said situation is that motor oil manufacturers are forced to keep widening their assortment of motor oils, which renders oil development and production considerably more expensive. Especially difficult is the position of small-scale oil manufacturers who find it very difficult to meet the increased costs of testing a large number of motor oils.
