Purpose and Specifications

LIQUI MOLY Special Tec F ECO 5W-20 is a fully synthetic premium engine oil engineered for Ford EcoBoost engines and select Jaguar Land Rover models. Its 5W-20 viscosity flows smoothly at cold starts down to -30°C for instant protection, while staying thick enough at 100°C+ operating temps to shield high-performance parts from wear. Special additives keep your engine exceptionally clean by preventing sludge buildup, deliver reliable lubrication under extreme loads, boost fuel economy by up to 2-3%, and resist aging for long-lasting performance. Meets strict specs: API SN, ACEA C5, Ford WSS-M2C948-B, Jaguar Land Rover STJLR.03.5004. 1L bottle perfect for precise top-ups or small engines.

When to Use / Replace?

Use this oil in Ford EcoBoost gasoline engines (except Ka 08/2008, Focus ST/RS with 2.5L Duratec-ST) requiring WSS-M2C948-B spec, plus compatible Jaguar Land Rover vehicles. Ideal for daily drivers, spirited highway runs, and temps from -30°C to 120°C+. Replace every 10,000-15,000 km or 12 months per Ford guidelines, or sooner if towing/heavy use. Shelf life: 5 years unopened in cool, dry storage.
