How to do a BMW oil change yourself: step by step

A BMW oil change is one of the most useful jobs you can learn to do yourself. Fresh oil protects the engine, and doing the job at home lets you use the oil you trust, change it more often if you wish and inspect your car at the same time.

The job is straightforward on most BMWs, but there are a few BMW-specific details, such as the top-mounted oil filter housing on many engines, the electronic oil level and the service reset. This step-by-step guide explains everything you need to know.

Before your BMW oil change: safety

Safety comes first. Never work under a car supported only by a jack. Use ramps on level ground or a jack with proper axle stands placed at the correct lifting points. Our community guide on DIY safety explains how to lift and support a BMW safely.

Let a hot engine cool down for a while. Hot oil drains better, but very hot oil and exhaust parts can cause burns. Wear gloves and eye protection, and keep the area clean and well lit.

Tools and parts

You will typically need:

• The correct engine oil with the BMW approval for your engine. Our article on BMW M engine oil explains approvals and viscosities.
• A new oil filter kit, usually including the filter element and new seals.
• A new drain plug seal or a new drain plug if specified.
• A socket or wrench for the drain plug.
• An oil filter housing tool that fits the filter cap.
• A torque wrench for the drain plug and filter cap.
• A drain pan large enough for the oil capacity.
• Tools to remove the engine undertray, if fitted.
• Gloves, rags and a funnel.

Check the oil capacity and torque values for your engine in the service information or the owner's documentation.

Step 1: Open the filter housing

On many BMW engines, the oil filter sits in a housing on the top or side of the engine, accessible from the engine bay. Opening it first lets air into the system, so the oil drains faster.

1. Clean the area around the filter cap.
2. Loosen the cap with the filter tool.
3. Lift out the cap with the filter element, letting oil drip back into the housing.
4. Remove the old seals from the cap.

Some engines have the filter in a different location. Check the procedure for your engine before you start.

Step 2: Drain the oil

1. Remove the undertray if needed.
2. Place the drain pan under the drain plug.
3. Loosen and remove the drain plug carefully. The oil will flow out quickly.
4. Let the oil drain completely.
5. Clean the drain plug, fit a new seal and refit it.
6. Tighten it to the specified torque. Overtightening can damage the oil pan, which is often made of aluminium or plastic on modern BMWs.

While the car is lifted, look underneath for leaks, damaged parts or worn components. Our article on BMW oil leaks explains common leak points.

Step 3: Fit the new filter

1. Fit the new seals to the filter cap. Lubricate them lightly with fresh oil.
2. Insert the new filter element into the cap or housing as specified.
3. Screw the cap back on by hand, then tighten to the specified torque.

Do not overtighten the cap. Plastic caps can crack, and overtightened caps are difficult to remove next time.

Step 4: Refill and check the BMW oil level

1. Pour in the specified amount of oil, slightly less at first.
2. Start the engine and let it idle for a short time. The oil pressure warning should go out within seconds.
3. Switch off the engine and check for leaks at the drain plug and filter.
4. Check the oil level.

Many modern BMWs have no dipstick. The oil level is measured electronically and displayed in the instrument cluster or iDrive. The measurement often requires the engine to be warm and the car to be on level ground, and it can take a few minutes. Top up gradually until the level is correct. Avoid overfilling.

Step 5: Reset the service indicator

BMWs use Condition Based Service to show when the next oil change is due. After the oil change, the service indicator should be reset. On many models this can be done through the instrument cluster or iDrive menu, following the procedure in the owner's manual. Some older models need a sequence of button presses or a diagnostic tool.

Our article on BMW Condition Based Service explains how the system works. Record the date, mileage and oil used in your service history.

How often to change the oil

The service indicator shows the official interval, but many enthusiasts change the oil more often, especially on M engines, turbo engines and cars that are used on track or for many short trips.

A common approach is to change the oil at shorter intervals than the maximum. Discuss the right interval for your car and use with a specialist. Always dispose of used oil and filters at an approved recycling point, never in drains or household rubbish.

Frequently asked questions

Can I change the oil on my BMW myself?

Yes. With the correct oil, filter, tools and safe lifting, it is one of the most practical DIY jobs.

How do I check the oil level on a BMW without a dipstick?

Use the electronic oil level display in the instrument cluster or iDrive, with the engine warm and the car on level ground.

Does changing the oil myself affect the warranty?

Using the correct approved oil and filter and keeping records is important. Check the warranty conditions for your car and market.

How do I reset the BMW service light after an oil change?

On many models, through the instrument cluster or iDrive menu, following the owner's manual. Some older models need a diagnostic tool.
