Oil Change DIY for BMW 335i: A Step-by-Step Guide

Performing an oil change on your BMW 335i not only ensures your engine runs smoothly and efficiently but also helps extend its lifespan. While some car owners prefer taking their vehicles to a professional mechanic, doing it yourself can save you time and money. In this DIY guide, we will walk you through the oil change process for your BMW 335i.

What You'll Need:

• Car Jack or Ramps
• Oil Filter
• Oil Drain Pan
• Socket Wrench Set
• New Oil (Check your owner's manual for the recommended oil type and viscosity)
• Funnel
• Rags and Gloves

Step-by-Step Guide:

1. Preparation:

Park your BMW 335i on a level surface and engage the parking brake. Allow the engine to cool down for at least 20 minutes before starting the oil change process.

2. Access the Oil Drain Plug:

Locate the oil drain plug underneath the engine. You may need to use a car jack or ramps to elevate the front of your vehicle for better access. Once elevated, place an oil drain pan beneath the oil drain plug.

3. Drain the Old Oil:

Using a socket wrench, carefully loosen the oil drain plug and let the old oil drain out into the oil drain pan. Allow all the old oil to completely drain and ensure the drain plug is securely tightened back into place.

4. Replace the Oil Filter:

Locate the oil filter, which is usually attached to the engine block. Carefully remove the old oil filter by turning it clockwise (righty-tighty) using an oil filter wrench. Clean the area around the oil filter housing and apply a thin layer of new oil to the rubber gasket of the new oil filter. Screw the new oil filter in place by turning it counter-clockwise (lefty-loosey).

5. Refill with New Oil:

Locate the oil filler cap on the top of the engine, usually indicated by an oil can symbol. Remove the cap and insert a funnel into the opening. Slowly pour the recommended amount of new oil into the engine. Refer to your owner's manual for the correct oil capacity. Once filled, replace the oil filler cap.

6. Check the Oil Level:

Start your BMW 335i and let it run for a few minutes to circulate the new oil. Turn off the engine and wait for a few minutes to allow the oil to settle. Check the oil level using the dipstick located near the oil filler cap. The oil level should be within the designated range on the dipstick. If needed, add more oil and recheck until the level is correct.

7. Clean Up and Dispose of Old Oil:

Wipe off any spilled oil and replace the oil drain plug and filter wrench. Dispose of the old oil responsibly by taking it to a recycling center or an auto parts store that accepts used oil.

Performing a DIY oil change for your BMW 335i can be a rewarding task that helps keep your car in optimal condition. Remember to follow proper safety precautions and consult your owner's manual for specific instructions and recommendations.
