Disadvantages of the EL15 engine

  • Almost all the problems of this power unit are somehow related to oil;
  • Oil consumption here starts from the first kilometers and progresses strongly to 100,000 km;
  • The unit is prone to leaks, and with a low level of lubrication, it can turn the liners;
  • The engine is very thermally loaded, and the cooling system is not famous for its reliability;
  • The reason for floating rpm is usually electronic throttle glitches.
