The 1.5 L Ecoboost engine typically holds 4.05 liters (0.9 gallons) of engine oil when the oil filter is replaced during a full oil change service.
Engine Oil Capacities for the 1.5 L Ecoboost
Understanding the precise oil capacity for your 1.5 L Ecoboost engine is crucial for proper maintenance and longevity. The total volume of engine oil required can depend slightly on whether the oil filter is also changed during an oil service, which is generally recommended.
Here's a detailed breakdown of the oil capacities:
| Item | Capacity (Liters) | Capacity (Gallons) |
|---|---|---|
| Engine oil fill capacity including the oil filter | 4.05 L | 0.9 gal |
| Engine oil fill capacity excluding the oil filter | 3.75 L | 0.8 gal |
Why the Oil Filter Affects Capacity
When you perform an oil change, it's standard practice to replace the engine oil filter at the same time. The oil filter itself retains a small amount of oil, and replacing it means you'll need to add that extra volume to reach the correct fill level. If for some reason you were to only drain and refill the oil without replacing the filter, a slightly smaller amount of oil would be needed, as indicated in the table.
Best Practices for Maintaining Engine Oil Levels
- Always change the oil filter with every oil change. This ensures optimal filtration and contributes significantly to engine health and longevity.
- Use the correct oil type as specified in your vehicle's owner manual. This includes the correct viscosity (e.g., 5W-20 or 5W-30) and the specific oil standard (e.g., API SN, ILSAC GF-5, or Ford's proprietary specifications like WSS-M2C948-B, depending on your model year).
- Check the dipstick after filling to ensure the oil level is within the recommended range. It's often best to add slightly less than the full capacity initially, run the engine for a minute, then let it sit for a few minutes on level ground before checking the dipstick. Add small amounts as needed until the correct level is achieved between the "MIN" and "MAX" marks. Overfilling can be as detrimental as underfilling.
