Blue 1-Gallon Undiluted Antifreeze

The Genuine BMW Blue Antifreeze is a 1-gallon jug of undiluted ethylene glycol-based coolant, specifically formulated for BMW and MINI cooling systems. This coolant is the familiar blue color (G48 formula) used by BMW since the 1990s and is factory-recommended, ensuring it meets BMW's stringent standards without nitrites, amines, phosphates, or borates. This coolant is intended for use in BMW vehicles up to the 2018 model year. It is crucial to mix this concentrate with distilled or demineralized water, typically at a 50/50 ratio for most environments. For colder climates, a 60/40 coolant-to-water ratio is recommended for enhanced freeze protection. Mixing different coolant formulas should be avoided; off-the-shelf coolants from general auto parts stores are often not compatible with BMW cooling systems.
