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

LIQUI MOLY Special Tec B FE 5W-30 is a BMW Longlife-01 FE approved engine oil, sold in a 5-liter container, for the BMW and Mini gasoline engines in the fitment table. LIQUI MOLY developed it mainly for BMW gasoline engines without a particulate filter from model year 2002 onward, along with selected BMW M models. Along with the BMW approval, it carries the ACEA A5/B5 and API SL ratings. LIQUI MOLY has tested it for use with turbochargers and catalytic converters, so the same oil covers both turbocharged and naturally aspirated engines in this range. It is made in Germany by a company founded in Ulm in 1957, which still develops and produces its motor oils there.

LIQUI MOLY engine oil carries a 24-month or 24,000-mile warranty.

Choose engine oil by approval first and viscosity second. The B FE name refers to the BMW Longlife-01 FE specification, so this container is meant for engines whose service data calls for that standard and that have no particulate filter. An engine that BMW specifies for a different Longlife standard should get the oil that carries that approval. Part 20444 cross-references several BMW oil numbers, including 83212365950, 83212365946, and 83212466454. That helps when you are matching an older service record or an invoice that shows a BMW number instead of a LIQUI MOLY one. Engine oil does more than lubricate. It carries heat away from bearings and pistons and holds combustion byproducts in suspension until the next drain.
