Running in of the new engine

During the first thousand kilometers rubbing parts of the engine (pistons and cylinders; bearings of sliding and shaft) should have possibility to be earned extra. It is necessary, that it occurred at low loading and low frequency of rotation. The subsequent engine capacity and term of its service depend on it. Therefore:

  • Do not squeeze out full "gas"; if you have an automatic transmission, prevent the provision of full loading and sharp pressing against the stop on an accelerator pedal. Maximum frequency of rotation: 4200 rpm!
  • Squeeze out more than 4200 rpm not earlier, than the engine will reach working temperature; at the cold engine be switched earlier.
  • When passing the first 1000 — 1500 km the engine should be dispersed gradually till the maximum speed or the most admissible frequency of rotation (quickly 6300 rpm).

 Help: everything that here was told about the new engine, it is even more necessary to consider at the engine passable a running in after major maintenance which, as we know, reacts to the wrong manner of driving more sensitively.
