ULTRA X 5W-40

  • Application

    100% synthetic multi-grade motor oil recommended for use in petrol and diesel engines (without

    DPF). Especially suited for passenger cars and light duty trucks with turbo chargers to

    provide maximum protection in demanding, high-performance driving conditions.

  • Description

    FERTAN ULTRA X 5W-40, with its refined formulation, ensures reduced fuel and oil consumption,

    making it an eco-friendly choice for conscientious drivers. Its superior viscosity-temperature

    behavior grants it a multigrade characteristic, enabling year-round usage even in regions

    experiencing significant daily and/or seasonal temperature shifts.

    The incorporation of a special booster has elevated its quality to meet API SN standards, enhancing

    its performance in terms of oxidation stability, deposit prevention, wear protection, and

    cold-weather operation. These advancements contribute to a cleaner engine environment and

     

    extend the service life of your vehicle, ensuring it remains in peak condition for longer periods.
