Ford’s 7.3L V8 “Godzilla” engine is known for its robust performance and exceptional durability, especially in Super Duty pickups like the F-250 and F-350. Introduced in 2020, this engine serves as a powerful, gasoline-based alternative to diesel models, offering up to 430 horsepower and 475 lb-ft of torque. But what keeps this beast running strong? Oil and lots of it.
Ford 7.3 Gas Engine Oil Capacity
The Ford 7.3L gas engine has an oil capacity of 8 quarts (7.6 liters) when including the oil filter. This capacity applies to all model years of the engine starting from its introduction in 2020 and is essential for maintaining proper lubrication, temperature control, and engine performance.
Using the correct amount of oil helps avoid under-lubrication, overheating, or pressure issues that can lead to costly damage.
| Model Year | Oil Capacity (With Filter) |
|---|---|
| 2020 | 8.0 quarts |
| 2021 | 8.0 quarts |
| 2022 | 8.0 quarts |
| 2023 | 8.0 quarts |
| 2024 | 8.0 quarts |
It’s highly recommended to use SAE 5W-30 full synthetic oil that meets Ford’s specifications (such as API SP or SN Plus and WSS-M2C961-A1).
Always check the dipstick after refilling to ensure the level is between the “MIN” and “MAX” marks. Regular oil checks and timely changes will help maximize the life and reliability of your Ford 7.3 V8 engine.
