Duckhams is one of Britain’s best-known names in engine oil, with roots dating back to 1899, when chemist and entrepreneur Alexander Duckham founded the company in London. Over the decades, Duckhams built a reputation for lubricant innovation and performance, becoming closely associated with British motoring history and motorsport culture. Today, Duckhams offers a structured portfolio that serves multiple vehicle types and operating conditions: Modern passenger car oils: The QXR range is positioned as fully synthetic, high-performance engine oil developed for modern engines and low-viscosity requirements (including ultra-low grades such as 0W-20 and 0W-16 in the line-up, product dependent). Everyday and workshop-friendly options: The QS range covers widely used viscosities and “C” category variants (e.g., C2/C3/C4 naming in the product family), supporting compatibility-led servicing where the correct specification matters.  Commercial and fleet lubricants: Fleetmaster oils are presented for heavy-duty diesel applications, with SHPD-style products aimed at high-performance diesel engines (including turbocharged and naturally aspirated).  Classic and heritage oils: Classic Q 20W-50 is described as the original green multigrade motor oil and is marketed for older/higher mileage classic engines, aligning with long-standing handbook recommendations. Alongside engine oils, Duckhams also supplies drivetrain fluids—such as manual transmission oils, CVT fluid, DCT fluid and ATF—helping workshops and motorists source a consistent brand across routine servicing needs.
