Disadvantages of the Mazda BP 1.8l engine

  • This power unit is famous for its reliability, but often consumes oil;
  • Lubrication consumption here usually appears even before 100,000 km and only grows with mileage;
  • The cause of floating engine speeds is most often throttle contamination;
  • The timing belt runs 100,000 km according to the regulations, but when it breaks, the valves never bend;
  • Hydraulic compensators do not tolerate low-quality oil and very often fail.
