How to change the oil on a 1968 Ford Mustang GT Fastback (Bullitt)?

Changing the oil on a classic 1968 Ford Mustang GT Fastback (Bullitt) is a crucial maintenance task that helps to keep the engine running smoothly and prolong its lifespan. Over time, the oil can become dirty and less effective at lubricating the engine's components, which can lead to wear and potential engine damage. Symptoms that indicate the need for an oil change include dark, dirty oil, the oil change light appearing on your dashboard, or if it's been over 3,000 miles since the last oil change. Here is how to solve this issue.

Step 1: Gather Your Supplies

Before you begin, make sure you have the following items:

• New oil (about 5 quarts of 10W-30 motor oil, but check your owner's manual for specifics)
• New oil filter
• Oil filter wrench
• Socket wrench set
• Oil drain pan
• Funnel
• Rag or paper towels
• Car jack and jack stands

Step 2: Position Your Car

Park your Ford Mustang on a flat, level surface and engage the parking brake. You'll need to lift the front of your car to access the oil drain plug and oil filter. Use a car jack to raise the vehicle and secure it with jack stands.

Step 3: Locate the Oil Drain Plug

Crawl under the car from the front. The oil drain plug is located at the bottom of the oil pan, which sits beneath the engine. It’s usually a bolt-like object, often with a slightly wider head, that requires a socket wrench to remove.

Step 4: Drain the Old Oil

Place the oil drain pan directly beneath the oil drain plug. Use a socket wrench to loosen and remove the drain plug. Be prepared for the oil to flow out rapidly. Allow all the oil to drain into the pan; this may take a few minutes.

Step 5: Replace the Oil Filter

Locate the oil filter, which is typically found mounted on the side of the engine block. It looks like a small metal canister. Use the oil filter wrench to twist off the old filter. Have your oil drain pan ready as some oil might spill out. Take your new oil filter and place a small amount of new oil onto the rubber gasket (this helps ensure a good seal). Screw the new filter on by hand until it’s snug, then give it an extra quarter-turn to ensure it’s tight.

Step 6: Reinstall the Oil Drain Plug

Once the old oil has fully drained, replace the oil drain plug and tighten it with a socket wrench. Do not over-tighten, as this can strip the threads.

Step 7: Add New Oil

Open the hood of your Mustang and locate the oil filler cap. This is usually found on the top center of the engine and is marked with an oil can symbol. Unscrew the cap and place a funnel into the filler neck. Pour the new oil into the funnel, adding about 4 quarts to start. Replace the oil filler cap.

Step 8: Check the Oil Level

Lower the vehicle from the jack stands. Start the engine and let it run for a minute, then shut it off. Wait a couple of minutes and then check the oil level using the dipstick. Pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again. The oil level should be between the "Min" and "Max" marks. If it’s low, add more oil as needed.

Step 9: Dispose of Old Oil

Pour the used oil from the pan into a sealable container and take it to a recycling center or auto shop that accepts used motor oil for proper disposal.

By following these steps, you’ll ensure that your 1968 Ford Mustang GT Fastback continues to run smoothly with fresh, clean oil. Regular oil changes are essential for maintaining the performance and longevity of your classic car.
