N47 Oil Capacity, Grade & Service Data

The BMW N47 four-cylinder diesel engine (used across the E90 3 Series, F10 5 Series, E84 X1, and many others) requires a specific oil capacity, grade, and BMW Longlife approval. This page gives you the factory figures, the real-world caveats, and the one service detail that directly affects timing-chain health.

The BMW N47 takes 5.2 litres with filter change (5.0 litres without) of 5W-30 oil meeting BMW Longlife-04 (LL-04) approval [PLACEHOLDER — confirm vs OEM workshop data].

Full specification table, variant differences, common mistakes, and the service interval caveat explained below.

Variant Differences

The N47 was fitted across several BMW models and chassis codes. While the core specification is consistent, sump capacity and filter access vary slightly by application.

Notes & Caveats

The factory 18,000-mile oil-change interval for the N47 is a known tension point in the BMW community. Independent specialists we've spoken to consistently recommend a shorter, 8,000-mile interval for N47 engines, regardless of what the service computer indicates [EM-INTERVIEW]. The reason is the timing-chain guide system: extended oil intervals allow the oil to shear and accumulate contaminants, which accelerates wear on the plastic chain guides. A full mechanical explanation of this failure mode is available on our N47 Timing Chain Failure page, where we cover the diagnostic sequence and replacement costs.

In real UK driving conditions, the 18,000-mile factory interval is often too long. Short urban journeys, cold starts, and stop-start traffic all degrade the oil more quickly than the BMW service schedule assumes. This is why specialist advice tends toward halving the interval — it adds a service cost, but it is cheap compared to a timing-chain replacement or a full N47 rebuild.

Common Mistakes

How to Verify on the Actual Vehicle

The N47's oil filler cap is marked with the correct grade and is accessible from above without removing panels. The dipstick is also located on the top of the engine, making checks straightforward. Confirm your exact build spec via the engine number stamp described on our Engine Number Location guide before assuming these figures apply — early and late N47 production runs occasionally carry minor specification changes that are not always reflected in aftermarket reference sources.

Why This Specification Matters

Getting the oil specification wrong on an N47 is not a minor mistake. The engine's timing-chain guides, turbocharger, and DPF all rely on the correct oil pressure, shear stability, and low-SAPS formulation. Using a non-LL-04-approved oil can lead to chain guide wear, DPF clogging, and ultimately timing-chain failure — a repair that typically costs £1,500–£3,000 at an independent specialist (see our Replacement Cost by Engine Code guide for up-to-date figures).

The viscosity grade matters similarly: 5W-30 is specified for cold-flow characteristics that directly affect how quickly oil reaches the chain guides and bearings on a cold UK morning. This is also why the N47 Timing Chain Failure page describes oil-change frequency as a primary preventative measure — not just a service suggestion.
