For the 2008 Ford Fusion with the 2.3-liter Duratec four-cylinder, plan on about 4.5 quarts (roughly 4.3 liters) of engine oil when performing a full oil change with a new filter. Use 5W-20 oil as the default grade, and verify exact specifications in your owner's manual or with a Ford dealer for your VIN, as oil capacity can vary slightly by market or model year.
Oil capacity and recommended oil grade
The following details summarize typical capacity, filter impact, and the recommended viscosity for this engine.
- Oil capacity with a new filter: 4.5 quarts (4.3 liters)
- Oil capacity without the filter: about 4.0 quarts (3.8 liters)
- Recommended viscosity: 5W-20 is standard for most climates; 5W-30 can be used in hotter climates or per manual
- Change interval guidance: 5,000 miles under normal conditions with conventional oil; 7,500 miles with approved synthetic oil, or per Ford owner's manual
Note: These figures are typical for the 2008 Fusion with the 2.3L Duratec; always refer to the exact spec printed in your manual or on the radiator decal for your vehicle’s market and VIN.
Oil grades by climate and dealer advisories
Ford generally recommends 5W-20 for the Duratec 2.3L, with 5W-30 often acceptable in very hot climates or for vehicles with particular service conditions. Always confirm with your dealer or the owner's manual for your specific region and engine version.
Practical steps for an oil change (high level)
When performing your own oil change, you typically drain the old oil, replace the filter, and refill with the recommended amount of oil. Here is a practical guide to expected steps and checks.
- Prepare the right parts: 4.5 quarts of oil, new oil filter, drain pan, and appropriate tools
- Drain old oil completely and replace the filter
- Fill with oil gradually and check level with the dipstick
- Run the engine, turn off, recheck for leaks and oil level, top up if needed
Following these steps helps ensure you reach the recommended oil capacity and maintain proper engine lubrication.
Summary
Bottom line: For a 2008 Fusion 2.3 L Duratec, expect to put about 4.5 quarts of oil with a new filter, using 5W-20 as the default viscosity, and follow the standard maintenance schedule. Always verify exact specs in the owner's manual or with a Ford dealer to account for any regional variations or VIN-specific requirements.
