The automotive technical servicing system includes several kinds of technical activities, technical service, current repair and diagnostics. One of essential elements of the car technical service system is mileage in between servicing. During technical servicing oil is replaced, diagnostics and other servicing work planned by the car producers is performed. The automobile producers increase the car mileage in between servicing following marketing trend. If for highly forced engines the mileage in between servicing is technically groundlessly increased, it can lead to essential decrease of resources of motors and other systems. The aim of research is to determine influence of infrequent servicing of vehicle on vehicle service life. According to the results of the research infrequent technical servicing leads to premature decrease of the automobile’s engine service life.
