How To Change The Oil In A Mustang EcoBoost

Ford introduced the 2.3L EcoBoost 4-cylinder engine in the 2015 sixth-generation Mustang. By 2018, the 2.3L EcoBoost replaced the 3.7L Duratec V6 as the standard engine for Mustang. (Learn more about the how the EcoBoost engine works here.) If you own a 2015-present EcoBoost Mustang, you may be wondering how to change the oil and filter yourself. Here’s everything you need to know.  

Tools And Supplies You’ll Need

Doing your own oil change doesn’t require many tools and supplies. In fact, you may already have most of these basic tools. Here’s what you’ll need:

  • 15mm socket and ratchet
  • Oil filter strap wrench
  • Oil funnel and drain pan with storage container
  • Shop towels and gloves
  • Ramps or floor jack and jack stands
  • Wheel chocks
  • 6 quarts of SAE 5W-30 synthetic blend or full synthetic oil
  • FL-910S or FL-400S* oil filter

*Note: Oil capacity with the standard FL-910S oil filter is 5.7 quarts. However, the FL-400S is a direct fit with a larger capacity and better filtration. The oil capacity with the FL-400S is exactly 6.0 quarts.

Changing The Oil And Filter

  1. If the engine is cold, idle it for several minutes to heat up the engine. Warming the engine will allow the old oil to drain more thoroughly.
  2. Raise the vehicle to access the oil drain plug and filter. Either drive up on ramps or raise with a floor jack and secure with jack stands. Place wheel chocks behind the rear wheels. Warning: Always set the parking brake to prevent vehicle movement.
  3. Locate the oil drain plug on the back side of the oil pan. Place the drain pan underneath and slowly remove the 15mm drain plug with a ratchet and socket. 
  4. When the oil has drained, reinstall the drain plug. A good rule of thumb is to tighten the plug until snug, then another quarter turn. Caution: Do not overtighten.
  5. Locate the oil filter to the left of the oil pan. Place the drain pan underneath and slowly loosen the oil filter with the strap wrench.
  6. Ensure the old gasket is still in the filter and not stuck to the engine. Apply a thin coat of clean oil to the new oil filter's gasket and install the filter. A good rule of thumb is to tighten the filter until snug, then another quarter turn. Caution: Do not overtighten.
  7. Remove the engine oil cap and install a funnel to prevent oil spills. Fill the engine oil to capacity. (5.7 quarts with an FL-901S oil filter or 6.0 quarts with an FL-400S oil filter)
  8. Reinstall the oil cap and start the engine. Inspect for any oil leaks while the engine is running.
  9. Shut off the engine and check the oil level on the dipstick. See the owner’s manual for reading the oil level on the dipstick. 
  10. Reset the oil life indicator. See the owner’s manual for the oil life reset procedure.

The recommended oil change interval for the 2.3L EcoBoost Mustang is every 7,000 to 10,000 miles under normal driving conditions. See the owner’s manual for details on when to change the oil under more severe conditions.
