How many quarts of oil does a 4.6 GT take?
The typical oil capacity is five quarts with a new filter, which is about 4.7 liters. This is standard for Ford’s 4.6-liter Mustang GT engines across most model years.
The 4.6 GT refers to Ford’s modular 4.6L V8 used in several Mustang generations. While the exact capacity remains in the five-quart range for a normal oil change with a fresh filter, small variations can occur by year and trim. Always confirm the specification in your owner’s manual or service manual for your exact year and configuration.
Oil capacity by engine variant
Year-to-year differences
Below are the most common patterns for the 4.6L Mustang GT variants. The values assume a standard oil change using a new filter.
- 1996–2004 4.6L V8 (2-valve) — 5 quarts with filter.
- 2005–2010 4.6L V8 (3-valve) — 5 quarts with filter.
- General note — If you do not replace the filter, capacity may appear closer to 4.5 quarts; for accuracy and engine protection, always install a new filter and fill to the full recommended amount.
In practice, most owners will use a full 5-quart change with a new filter and verify the level on the dipstick after the engine has cooled slightly. This helps ensure the correct oil film is present across engine bearings and components.
How to fill and check oil
Follow these steps to ensure the oil level is correct after you change it and replace the filter.
- Park on level ground and run the engine briefly to warm the oil, then turn it off and allow it to settle for a few minutes.
- Open the hood, pull the dipstick, wipe it clean, reinsert fully, then pull it out again to check the level.
- If the oil level is below the full mark, add small amounts (about a 1/2 quart at a time) and recheck until you reach the full mark.
- Replace the dipstick, secure the oil fill cap, and run the engine for a minute before rechecking to ensure the level remains correct after oil circulation.
- Dispose of used oil and filter properly and wash up any spills.
Following these steps helps ensure you have the correct oil level for proper lubrication and engine longevity.
Bottom line
For a Ford Mustang GT with a 4.6L modular V8, plan on about five quarts of oil when performing a full change with a new filter. Confirm the exact capacity for your specific year and trim in the owner’s manual, and use the recommended oil grade for your climate and driving conditions.
Summary: The typical oil capacity for a 4.6 GT is five quarts with a new filter. Always verify the exact specification for your model year and follow proper filling and checking procedures to ensure accurate oil level and optimal engine protection.
