2019 2.3L I4 Engine
Raise Front of Vehicle
Partially Remove Dipstick
This automotive maintenance tutorial was specifically written to assist owners of the S550 sixth generation 2015, 2016, 2017, 2018, 2019, 2020, 2021 and 2022 Ford Mustang in changing the motor oil and replacing the oil filter on the EcoBoost 2.3 liter turbocharged inline four cylinder engine. (The procedure should be similar for the 5.0L V8, 5.2L V8 and 3.7L V6 engines.)

(The 7th generation S650 Ford Mustang is supposed to be released in 2022 as a 2023 model year vehicle.)

Owners of other Ford and Lincoln vehicles such as the Fusion, Taurus, Escape, EcoSport, Flex, Expedition, Bronco, Ranger, Transit, F-150, C-Max, Fiesta, Focus, Edge, MKZ, Continental, Corsair, Nautilus, Aviator and Navigator may also find these DIY instructions to be helpful.

A few compatible replacement oil filters for the Ecoboost 2.3L engine with their part numbers are as follows: Wix 51348, Purolator PL10241, Royal Purple 10-2835, Denso 150-2010, Fram PH3614 and Mobil 1 M1-102A.

The tools and other items needed to complete this procedure include a floor jack, two jack stands, wheel chocks, a 15mm socket with a 3/8" drive ratchet, a used oil catch basin, an automotive funnel and a Lisle 63600 oil filter wrench (optional).

The oil capacity specification for the EcoBoost 2.3L engine for an oil change with a filter replacement is 6.0 U.S. quarts (or 5.67 liters) of new SAE 5W-30 oil.

The first few steps are to warm up the engine, drive the vehicle on to a level surface, shift the transmission into "Park" and turn off the ignition.

Warming up the engine will suspend any contaminants within the old oil and also cause it to drain out more quickly.

Engage the emergency / parking brake and place wheel chocks on both sides of the rear tires to help prevent the car from moving.

Open the hood, partially remove the dipstick an inch or two and twist off the oil filler cap in the counterclockwise direction.


Twist Off Oil Fill Cap
Filler Cap Removed
Slide Under Car
Removing the oil fill cap and lifting up the dipstick will help prevent a vacuum from forming and also allow the old oil to drain out more quickly.

Carefully raise the front of the car with the floor jack and securely support it with at least two jack stands.

Please do not solely rely on the floor jack to support the car. You could also use a pair of automotive ramps.

Make sure the rear tires are chocked and the parking brake is firmly set.

Slide under the engine bay of the car with the used oil catch container, the 15mm socket and a 3/8" drive ratchet.

These pictures were taken from the passenger side of the engine bay.

Locate the silver metal oil pan and the silver metal oil drain bolt.

I marked the oil drain plug with a large blue arrow in the picture above.

The oil filter is situated on the driver side of the oil pan.

Old Oil Filter Location
Used Oil Catch Container
Loosen Counterclockwise
Move the used oil catch container to just below the drain bolt.

Be careful when you remove the drain bolt. The old oil might still be hot enough to burn your fingers depending on how long you warmed up the engine.

Loosen the drain bolt by turning it in the counterclockwise direction with the 15mm socket and a 3/8" drive ratchet or a 15mm wrench.

Drain Out Old Oil
Spin In Drain Plug
Tighten Drain Bolt
Spin out the drain bolt the rest of the way by hand.

Inspect the washer (or "gasket") on the drain bolt and replace it if necessary.

Allow the old oil to drain out for at least a few minutes or until the flow slows down to just an occasional drip.

Spin in the oil drain bolt a few turns by hand in the clockwise direction to make sure it doesn't become cross threaded.

If you have a torque wrench, tighten the oil drain bolt to the service manual specification of 20 lb-ft (27 Nm).

Double check that the drain bolt is tight before moving on to the next steps.

Spin Off Old Filter
Use Oil Filter Wrench
Loosen Counterclockwise
Spin off the old oil filter by turning it in the counterclockwise direction.

If the filter is very stubborn or stuck due to being over tightened at the dealership or a quick lube oil change service, I highly recommend using the Lisle 63600 oil filter wrench.

Attach the filter wrench to a short 3/8" drive extension bar and the 3/8" drive ratchet.

Rotate the old filter in the counterclockwise direction. Pull off the wrench once the filter is loose.

Carefully remove the old filter and allow the old oil to drain out for at least a few minutes.

Dip Finger In New Oil
Lubricate Rubber O-Ring
Spin On New Oil Filter
Dip your finger into some new oil and lubricate the rubber o-ring gasket on the new oil filter.

Lubricating the o-ring will help the filter form a better seal, prevent oil leaks and also make it easier to remove the filter during the next oil change.

Make sure the rubber o-ring from the old oil filter is not still attached to the engine.

Twist on the new oil filter in the clockwise direction until it makes contact with the engine.

Then continue tightening the filter another 1/2 to 3/4 of a turn past finger tight.

Try to avoid over tightening the new oil filter to prevent from damaging the rubber o-ring which could result in an oil leak.

Double check that the new oil filter is tight before moving on to the next steps.

Lower Car From Stands
Insert Automotive Funnel
Pour In New Oil
Carefully lower the vehicle from the jack stands by using the floor jack.

Insert the automotive funnel into the oil fill port.

According to the owner's manual for this 2019 Mustang, the total oil capacity specification for the EcoBoost 2.3L I4 engine for an oil change with a filter replacement is 6.0 U.S. quarts (or 5.67L) of new SAE 5W-30 oil.

Please double check your owner's manual for the correct oil capacity specification for your vehicle!

Since it is much better have to slightly less oil than necessary in an engine than to run an engine that has been over filled with oil, I recommend at first only pouring in about 5 to 5 1/2 U.S. quarts of the engine's 6.0 U.S. quart total capacity.

Slowly pour in the new oil.

Replace Oil Fill Cap
Push Down Dipstick
Warm Up Engine
Remove the funnel, replace the oil fill cap and push the dipstick all the way back in.

Start the engine and allow it to warm up to normal operating temperature.

Turn off the ignition and allow the new oil to drain back down to the oil pan for at least 15 minutes.

Check Oil Level
Replace Dipstick
Oil Change Done!
Pull out the dipstick, wipe it clean with a paper towel, fully re-insert the dipstick and pull it out again to check the oil level.

If necessary, slowly pour in more oil and repeatedly check the level on the dipstick until it reaches at or just below the upper hole in the dipstick which indicates the "Full" or "MAX" (maximum) line.

You may not need to pour in the entire 6 U.S. quarts of oil in order for the level on the dipstick to reach the "MAX" line depending on how long you allowed the old oil to drain out.

Try to avoid overfilling the engine. Running an engine that has been overfilled with oil may cause damage to seals, gaskets or other components.

Make sure the dipstick is fully inserted and the oil fill cap is tight.

To reset the oil life meter, follow these steps: 1. From the Main Menu on the Information Display, choose "Settings" 2. Choose "Advanced Settings" 3. Choose the "Vehicle" option 4. Scroll down to "Oil Life" 5. Press and hold the "OK" button until the instrument cluster displays the "Reset Successful" message. 6. The oil change indicator should have disappeared and the oil life system should read "100%".

It's a good idea to check your parking space, driveway or garage floor for drops of fresh oil during the next few days which might indicate a leak from the drain bolt or the new oil filter. I would also check the oil level on the dipstick at least once a month or more often if you do any drag racing.

Be sure to write down the oil change in your vehicle's service records.
