BMW Transfer Case Oil DTF 1 DTF-1 83225A4F016 Genuine 1 L

✅ What is DTF-1 / 83225A4F016

·         DTF-1 is the OEM transfer-case fluid for BMW AWD / xDrive transfer cases (also called “transfer box” / “transfer case ATC”).

·         The part number is 83225A4F016 (often written 83-22-5-A4F-016).

·         A common (older) designation for this fluid was TF0870.

·         It is supplied in a 1-liter bottle — and the transfer case typically needs just under 1 liter for a full fill.

This fluid is not regular engine oil, gear oil or differential oil — it's specifically formulated for BMW transfer cases, where the AWD / xDrive system uses a multi-plate clutch unit and internal gearbox-type mechanisms that rely on a specialized “transfer-case fluid.”

🚗 Typical Fitment — Which BMW Models Use This Fluid

DTF-1 / 83225A4F016 fits many of BMW’s xDrive (AWD) and ATC-based ALL-WHEEL DRIVE transfer cases across a wide range of models. Examples (not exhaustive):

In short: if the BMW is AWD/xDrive and uses BMW’s ATC (active transfer case) or similar transfer box, DTF-1 is the correct fluid — but always confirm with chassis / VIN / specific transfer case type before buying, as older AWD systems or differentials may require different fluid types.

⚠️ Important Notes & Service Interval

·         BMW recommends draining and refilling transfer case fluid roughly every 50,000–60,000 miles.

·         The bottle (1 L) is typically sufficient for a full fill — no need for extra volume.

·         This fluid must not be substituted indiscriminately with regular gear oils (like 75W-90, 80W-90, etc.) unless explicitly specified for that transfer case. Many BMW ATC/xDrive systems require the specially formulated transfer-case fluid (DTF-1 / TF0870).
