Diagnostic Steps

1
Consult the vehicle owner's manual for manufacturer recommendations.
2
Check the current oil level using the dipstick.
3
Inspect the condition of the oil (color and texture).
4
Review the service history for previous oil change intervals.

Solution

1. Determine Oil Change Frequency

BMW recommends changing the oil in the E90/E91 models every 7,500 miles or 12 months, whichever comes first, under normal driving conditions.
For severe driving conditions (e.g., frequent short trips, extreme temperatures), consider changing the oil every 5,000 miles or 6 months.

2. Prepare for Oil Change

Gather tools: socket set, oil filter wrench, oil catch pan, funnel, and rags.
Purchase the correct engine oil (5W-30 is a common choice) and a new oil filter.

3. Perform Oil Change

Lift the Vehicle
- Use a jack to lift the front of the vehicle securely and place jack stands underneath.
Drain Old Oil
- Remove the oil drain plug using a socket wrench.
- Allow the old oil to completely drain into the catch pan.
Replace Oil Filter
- Use the oil filter wrench to remove the old oil filter.
- Apply a small amount of new oil to the rubber gasket on the new oil filter.
- Install the new oil filter by hand until snug (do not overtighten).
Add New Oil
- Replace the oil drain plug and tighten to the specified torque (usually around 25 Nm).
- Use a funnel to pour new oil into the engine through the oil filler cap.
- Check oil level with the dipstick and add more oil if necessary.
Run Engine
- Start the engine and let it run for a few minutes.
- Check for leaks around the oil drain plug and oil filter.

4. Reset Oil Change Indicator

Use the vehicle's onboard computer system to reset the oil change indicator light if applicable.
