MultiAir System Britiures

Te MultiAir system is a hydraulic variable valve- lift technology that replaces thee traditional camshaft on thee intake valves. It allows precise control of air intake, improwing g power and fuel efficiency. However, this system is entirely dependent on consistent oil pressure and clean oil. Contaminated or low oil can destruy the MultiAir brick, leading to rough idle, loss of power, and a perstent check engine light.

  • Rekomendacje FLT: 0 + 3; Signal Oil Change Intervals: Signa1; Signal 1; FLT: 1 + 3; Signal dealter recommendations may push 8,000 t o 10,000 mils, a 5,000 - mile oil change interval is strongly recommended for all MultiAir- equipped ators. This prevents sludge andd varnish buildup that cat clog the microscopic oil passages with in the MultiAir actubator.
  • Reference: API SN or SP rated oil with thee correct visosity (0W- 20 for thee 2.4L, 5W- 40 or fly synthetic 0W- 40 for thee 1.4L MultiAir Turbo). Using thee wrong visity can cause erratic valve timing and potential infault.
