LIQUI MOLY Special Tec B FE 5W-30 Engine Oil (1 Liter) for BMW and Mini (1991–2025)

Approved to BMW Longlife-01 FE, LIQUI MOLY Special Tec B FE 5W-30 20442 is an engine oil sold in a 1-liter bottle for BMW and Mini gasoline engines. LIQUI MOLY developed it primarily for BMW gasoline engines without a particulate filter from model year 2002 onward, along with selected BMW M models. It is tested for use with turbochargers and catalytic converters. Beyond the BMW approval, it carries ACEA A5/B5 and API SL ratings. It is made in Germany.

LIQUI MOLY Special Tec B FE 5W-30 carries a 24-month or 24,000-mile warranty.

The Longlife-01 FE approval is the specification to match. BMW sets oil requirements by engine, and an oil carrying a given BMW approval meets the minimum requirements BMW defines for that standard. This oil cross-references to a long run of BMW oil part numbers, among them 07510143829, 83212365953, 83212365947, and 83212466455, which is useful when matching it against the factory oil shown in a service record. Engine oil lubricates the crankshaft bearings, camshafts, and piston rings, carries heat away from parts the coolant cannot reach, and holds combustion byproducts in suspension until the next change. In a 5W-30 grade, the 5W figure describes how readily the oil flows at a cold start and the 30 describes its thickness at operating temperature.
