- The paper presents the results of lubricating properties tests of Marinol RG 1240 motor oil used in trunk piston marine diesel engines and modified by chemical interaction aftermarket additives – Motor Life Professional and Mind. The test results were collected by means of a four-ball extreme pressure tester T-02 according to Polish Norm PN-76/C-04147. The following lubricating properties parameters were determined: weld load Pz, maximum nonseizure load Pn, seizure load Pt, load wear index Ih and load limit of wear Goz. Investigations showed that tested chemical interaction aftermarket additives improve load wear index Ih, and seizure load Pt (in case of Motor Life Professional), simultaneously impair maximum non-seizure load Pn. Weld load Pz remains on the same level. But the load limit of wear Goz which characterises the wear resistance in extremely hard working conditions increases considerably- 542% for tested oil with the addition of 5% by volume of Motor Life Professional and 520% with the addition of 5% by volume of Mind additive. These results indicates that tested aftermarket additives can form additional boundary layer (independent of lubricating oil boundary layer) which activates in extreme working conditions (very high temperatures and loads) of the sliding node elements. That layer could protect machines elements against seizure. In authors opinion, modifying of motor oils (provided with antiwear and antiseizure additives by the manufacturer) by chemical interaction aftermarket additives can increase durability and reliability of the machine elements especially in hard working condition for example frequent starts and load changes, overloads, operation in polluted atmosphere (transport, mining, building engineering etc.).
