Why choose QS 5W-30 SP C3

Duckhams QS 5W-30 SP C3 is a shear-stable, long-life, fully synthetic multigrade engine oil, formulated using modern additive technology and high-quality synthetic base oils to provide advanced protection for modern petrol and diesel engines. It is also recommended for hybrid engines. Duckhams QS 5W-30 SP C3 maintains engine performance throughout extended oil drain intervals, helping to reduce running costs. It keeps the engine clean by reducing sludge and deposit formation, provides easy cold starting and reliable lubrication at high operating temperatures, and helps keep oil consumption low.

  • Meets the API SP low-speed pre-ignition (LSPI) test requirement, helping protect modern small, turbocharged petrol engines against LSPI damage.
  • Shear-stable formulation maintains the viscosity of the oil, providing anti-wear and corrosion protection throughout extended oil drain intervals, whatever the driving style, reducing component wear and extending engine life.
  • Thermally stable formulation reduces sludge and deposit formation, keeping the engine clean and running at its full potential from oil change to oil change.
  • Excellent low-temperature performance gives easy cold starting and fast oil circulation, minimising wear at start-up.
  • Low-friction synthetic oil reduces internal engine friction, improving efficiency and reducing running costs.
  • Low-volatility synthetic base oil reduces oil consumption and oil thickening.
  • Also recommended for hybrid engines.
