The typical engine oil capacity for a BMW 328i is about 6 quarts (5.7 liters), including the oil filter. Exact capacity varies by generation and engine code, so always confirm with the owner's manual for your specific car.
BMW’s 328i badge has appeared on several generations with different engines, from naturally aspirated six-cylinders to turbocharged four-cylinders. Because the oil capacity can shift slightly with design changes and regional specifications, it’s prudent to verify the precise figure for your model year and engine code before performing a change.
Oil capacity by common 328i variants
Below is a quick reference for typical capacities on commonly seen 328i variants. The numbers are approximate and intended as a guide; always cross-check the exact specification for your vehicle.
- E9x generation (2007–2013) 328i with the N52 3.0L inline-6: approximately 6.0 quarts (5.7 liters) including the filter.
- F30/F31 generation (2012–2015) 328i with the N20 2.0L turbo: approximately 6.0 quarts (5.7 liters) including the filter.
In practice, these figures cover the vast majority of 328i models sold in recent decades. For the exact amount on your car, consult the owner’s manual or the under-hood oil-cap label, and use the dipstick to confirm once the oil is added.
Practical tips and cautions
When changing the oil on a 328i, use a synthetic oil that meets BMW specifications and the regional requirement (often a 5W-30 or 0W-40, depending on climate and model year). Always replace the oil filter during a full drain and refill, and double-check the level after a short idle to ensure accuracy.
Summary
For most BMW 328i models, plan to add about 6 quarts (5.7 liters) of engine oil, including the filter. Exact capacity depends on engine code and generation, so verify with the owner’s manual or service label. Using the correct synthetic oil and following the manufacturer’s maintenance intervals will help maintain motor longevity and performance.
