When it comes to the oil capacity of the 1966 Mustang 289, there have been varying opinions among enthusiasts. According to some sources, a stock ’65 289 factory engine requires 5 quarts of oil to fill, including a filter change. However, others have mentioned that they could only fit 4 quarts, while some have stated that the filter fills up with about a quart of oil.
After thorough research, it has been confirmed that the actual oil capacity with a filter change is indeed 5 quarts. If the oil level appears to be too high after adding 5 quarts and running the engine, there may be an issue with the oil pan or dipstick. It is important to check the oil level after running the engine and adjust it accordingly.

Stay tuned for the next section, where we will explore how to properly change the oil in the 1966 Mustang 289.
How to Properly Change the Oil in a 1966 Mustang 289
When it comes to changing the oil in your beloved 1966 Mustang 289, it’s essential to follow the proper steps to maintain the optimal performance of your classic car. Here’s a step-by-step guide on how to do it right:
Gather the necessary tools and materials:
- Oil filter wrench
- Oil drain pan
- New oil filter
- 5 quarts of oil (including filter change)
- Oil filter gasket
- Oil filter adapter (if applicable)
Step 1: Prepare your car
Make sure your car is parked on a level surface and the engine is cool. This will help you avoid any accidents or burns.
Step 2: Locate the oil drain plug
Underneath the car, you’ll find the oil pan. Look for the oil drain plug, usually located at the bottom of the pan. Place the oil drain pan beneath it to catch the old oil.
Step 3: Drain the old oil
Using the appropriate wrench, loosen the oil drain plug and carefully remove it. Allow the old oil to drain completely into the drain pan. Once the oil has stopped flowing, securely tighten the drain plug.
Step 4: Replace the oil filter
Locate the old oil filter, typically attached to the engine block. Use the oil filter wrench to loosen it and remove it. Ensure that the old filter gasket is also removed, as leaving it behind can cause leaks.
Before installing the new oil filter, apply a thin layer of new oil to the gasket to ensure a tight seal. Screw on the new filter by hand, making sure it’s snug but not overly tight.
Step 5: Add the new oil
Refer to your owner’s manual or consult with a specialist to determine the optimal oil capacity for your 1966 Mustang 289. While there may be differing opinions on the exact oil capacity, it is generally recommended to start with 5 quarts of oil, including a filter change.
Remove the oil filler cap located on top of the engine, and place a funnel in the opening. Slowly pour in the new oil, being cautious not to overfill. It is also crucial to use the correct oil type based on your engine’s condition and preferences, such as 10W-30 or 10W-40.
After adding the new oil, replace the oil filler cap securely.
Step 6: Check the oil level
Start the engine and let it run for a few minutes to allow the new oil to circulate. After turning off the engine, wait for a few minutes before checking the oil level.
Remove the dipstick, wipe it clean, and reinsert it fully. Remove the dipstick again and observe the oil level. It should be between the “low” and “full” marks. If it’s too low, add a small amount of oil and recheck. If it’s overfilled, drain some oil until the level is correct.
Repeat this process until the oil level is in the optimal range.
Step 7: Dispose of the old oil properly
Old oil is hazardous and should be disposed of responsibly. Take the used oil, filter, and any other associated materials to a recycling center or an authorized disposal facility in your area.
And that’s it! You’ve successfully changed the oil in your 1966 Mustang 289, ensuring optimal performance and longevity for your classic ride. Remember to consult your owner’s manual or seek professional advice for specific oil system specifications and recommendations for your 1966 Mustang 289.
Factors to Consider when Choosing the Right Oil for a 1966 Mustang 289
When it comes to selecting the right oil for your 1966 Mustang 289, several factors should be taken into consideration. Engine condition, oil pressure, and personal preferences all play a crucial role in determining the optimal oil capacity for your vintage muscle car.
Some owners swear by synthetic oils, citing their superior performance and longevity. Others prefer traditional oils, relying on their proven track record and familiarity. Ultimately, the choice between synthetic and traditional oil boils down to personal preference and the specific needs of your engine. However, it’s essential to note that introducing synthetic oil to an older engine that may not be compatible can lead to potential issues.
Another crucial factor to consider is the use of a zinc oil additive, especially for engines equipped with flat tappet cams like the 1966 Mustang 289. These additives provide an extra layer of protection and help prevent premature wear and tear on critical engine components. They are particularly important for older engines that may not have been designed to accommodate modern oil formulations.
Additionally, selecting the correct viscosity is vital to maintain optimal performance. The recommended oil viscosity for the 1966 Mustang 289 is typically 10W-30 or 10W-40, depending on the engine’s specific requirements. Consult the owner’s manual or reach out to a specialist to ensure you choose the right viscosity for your engine.
Key Factors to Consider:
- Engine condition and age
- Oil pressure specifications
- Synthetic vs. traditional oil preferences
- Zinc oil additive for flat tappet cam engines
- Correct viscosity, such as 10W-30 or 10W-40
For precise oil recommendations tailored to your 1966 Mustang 289, it is always recommended to consult with a specialist or refer to the owner’s manual. They will provide expert guidance based on your engine’s unique requirements, helping you maintain optimal oil capacity and ensure the smooth operation of your classic car.
