摘要：

The efficiency of using of mineral engine oil modifier to restore compression of the cylinder-piston group of internal combustion engines is investigated. According to the results of full-scale tests of four different automobiles operating in an urban environment, the effect of increasing the compression of the cylinders to 20%, compared with the original, and reducing the pressure difference between them up to four times, was determinated. The effect reached a stable value after a run of 2000-4000 km and remained until the end of the experiment (10 000 km). It was found that when implementing the recommended procedure for flushing the engine before using oil with a friction modifier (FM), complete engine failure can occur. According to preliminary data the probability of this event is 20-30%.
