Naphthalene additives, as indicated in the literature review, are classified as detergent additives. Additives of this type are primarily used in engine oils. It is known that the composition of the “D” group oil should include an effective package of additives to achieve the level of performance properties, which ensures long-term performance of the most forced engines especially in severe operating conditions. To date, there is no universal method for assessing the behavior of oil at high temperatures, therefore oil is usually tested via several (laboratory and stand) methods. For example, in domestic practice, a four-stage system for determining the quality of newly created (experimental) oil products is provided.
