BMW 420i Gran Coupe Oil Change DIY

The BMW 420i Gran Coupe is a stylish and powerful vehicle that requires regular maintenance to keep it performing at its best. One important aspect of routine maintenance is changing the oil in your BMW's engine. While some may prefer taking their car to a professional mechanic for an oil change, others enjoy performing these tasks themselves. If you are confident in your DIY skills, here is a step-by-step guide to performing an oil change on your BMW 420i Gran Coupe.

What You Will Need:

• Oil filter
• Synthetic oil (check your car's manual for the recommended type and amount)
• A wrench or socket set
• Oil drain pan
• Funnel
• Rubber gloves

Step 1: Gather the Tools and Materials

Before you begin, make sure you have all the necessary tools and materials listed above. This will help ensure a smooth oil change process.

Step 2: Prepare your BMW

Park your BMW on a level surface and turn off the engine. It is also recommended to let the engine cool down for a while before performing an oil change to avoid any burns from hot components.

Step 3: Locate the Oil Drain Plug

Position yourself under the car and look for the oil drain plug. It is usually located at the bottom of the oil pan. You may need to use a wrench or socket set to loosen and remove the plug.

Step 4: Drain the Old Oil

Place the oil drain pan beneath the plug to catch the old oil. Once the drain plug is removed, allow the oil to fully drain out. Be patient and let it drip until it stops completely.

Step 5: Replace the Oil Filter

After draining the oil, locate the oil filter. It is typically situated near the drain plug. Unscrew the old oil filter using your hands or an appropriate filter wrench, taking care not to spill any excess oil. Make sure to properly dispose of the old filter.

Step 6: Install New Oil Filter and Tighten the Drain Plug

Before installing the new oil filter, apply a small amount of fresh oil to the rubber gasket. This will aid in creating a proper seal. Screw the new filter into place. Next, clean the drain plug and its washer, then thread the plug back onto the oil pan. Tighten it securely.

Step 7: Refill with New Oil

Using a funnel, carefully pour the recommended amount of synthetic oil into the oil filler cap located on top of the engine. Check your car's manual for the recommended type and quantity of oil. Once you've poured in the correct amount, replace the filler cap tightly.

Step 8: Check the Oil Level

Start the engine and let it run for a few minutes. Then, turn off the engine and wait for a couple of minutes to let the oil settle. Pull out the oil dipstick, wipe it clean, reinsert it completely, and pull it out again to check the oil level. If needed, add more oil to reach the optimal level.

Step 9: Clean Up and Recycle

Dispose of the used oil and filter responsibly at a local recycling center. Clean up any spilled oil and securely fasten the oil drain plug. Wipe down any surfaces that may have come into contact with the oil to avoid potential leaks or smell.

Performing an oil change on your BMW 420i Gran Coupe can be a rewarding experience, saving you both time and money. However, if you are unsure about any step or lack the necessary tools, it is always advisable to seek professional assistance to avoid any potential damage to your vehicle.

Remember, regular oil changes are essential to maintaining your car's performance and prolonging its lifespan. By following this DIY guide, you can enjoy the satisfaction of completing this task yourself and ensuring your BMW 420i Gran Coupe continues to run smoothly.
