Why choose Q 20W-50 SL
Q 20W-50 SL is a mineral engine oil for older petrol and light diesel cars that specify API SL or CF. Its thicker 20W-50 grade holds a strong oil film in high temperatures and in worn engines, helping to reduce oil consumption. Anti-wear and anti-corrosion additives protect engine parts, and detergents keep deposits under control.
- Good anti-wear properties protect the engine.
- Good Rust and Corrosion protection.
- Deposit control maintains engine cleanliness.
- Multigrade engine oil, suitable for year-round use.
- Low Volatility reduces oil consumption.
- Original, distinctive, Duckhams green colour.
