Complete reference for the BMW N20 2.0L turbo petrol engine – oil capacity with and without filter change, correct viscosity grade (5W-30), BMW Longlife-01 FE / LL-04 specification, and variant-specific differences across F30, F10, X1, X3, and other models.
The BMW N20 2.0L turbo petrol engine takes approximately 5.0 litres of engine oil with filter change, and 4.8 litres without [THIRD-PARTY — BMW TIS]. The correct specification is BMW Longlife-01 FE (5W-30) or Longlife-04 for most applications, with a change interval of 12,000 miles or 12 months under normal conditions, though many specialists recommend shorter intervals for turbocharged engines.

Data compiled from BMW Technical Information System (TIS) and verified with independent specialists. Figures marked [THIRD-PARTY] are sourced from public workshop data; [EM-INTERVIEW] denotes specialist consensus.
The N20 engine family includes several variants (N20B20, N20B20A, N20B20B, N20B20C, N20B20D) with minor differences in oil capacity and filter access.
| Variant | Typical Models | Capacity (with filter) | Oil Spec | Notes |
|---|---|---|---|---|
| N20B20 (early) | F30 320i, F10 520i (pre-2013) | 5.0 L | LL-01 FE | Cartridge filter, top access |
| N20B20A/B/C/D (2013+) | F30 328i, F10 528i, X1 20i, X3 20i | 5.0 L | LL-01 FE / LL-04 | Same capacity, revised oil pan |
| N20B20 (X1 E84) | X1 20i | 5.0 L | LL-01 FE | Same as F30, filter access different |
Always verify your exact engine code using the engine code decoder or VIN decoder to confirm the variant.
The N20 engine is a turbocharged direct-injection petrol, and oil choice is critical. BMW Longlife-01 FE is a low-ash oil designed for turbocharger protection – using an older LL-98 or non-approved oil can lead to turbo bearing failure and sludge formation. Many specialists recommend reducing the interval to 8,000–10,000 miles for high-performance or frequently driven cars [EM-INTERVIEW]. Additionally, the oil level should be checked regularly; some N20 variants are prone to oil consumption, especially with higher mileage.
For detailed information on timing chain and other common issues, see our N20 timing chain guide and N20 timing chain tensioner failure page.
The dipstick on the N20 is located on the left side of the engine block (driver's side in UK cars). The oil filler cap is on the top of the engine, usually marked with the oil specification. To confirm the exact capacity for your specific build, check the engine code stamp – it will be on a flat pad near the starter motor on the left side of the block. Use our engine number location guide to find it. Additionally, the BMW parts system using your VIN will provide the exact oil capacity and type for your vehicle – you can use our VIN decoder to get started.
Using the correct oil capacity and spec on the N20 is critical for turbocharger longevity, timing chain health, and overall engine performance. Overfilling can lead to oil aeration, which reduces oil pressure and can starve the chain tensioner – a known failure point on higher-mileage N20 engines. Underfilling can cause oil starvation, especially during hard cornering. Additionally, the LL-01 FE spec includes additives that protect the turbocharger bearings and reduce sludge formation, extending the life of both the engine and turbo. This is why we always recommend using the correct oil and sticking to the recommended change intervals – or even shortening them for peace of mind.
