2012 Focus 2.0L Engine
Spin Off Oil Filler Cap
Pull Up Oil Level Dipstick
This automotive tutorial was specifically written to assist owners of the third generation MK III (2011, 2012, 2013 & 2014) Ford Focus sedan or hatchback equipped with the 2.0 liter Duratec 20 Ti-VCT GDI inline four cylinder engine in changing the motor oil and replacing the canister oil filter.

Owners of other Ford vehicles with the Duratec 20 engine such as the Transit Connect, C-Max, Mondeo, EcoSport, S-Max, Fiesta and Galaxy may also find these DIY oil change instructions to be helpful.

The tools needed to complete this procedure include a floor jack, jack stands, a Torx T-30 star bit screwdriver, a 15mm socket with ratcheting wrench, a used oil catch container, a new canister oil filter, an oil filter wrench (optional), an automotive funnel and 5 quarts of new SAE 5W-20 oil.

A few compatible replacement oil filters with their part numbers are as follows: Mobil1 M1-102, Bosch D3330, Wix 51348, Purolator PL10241, K&N PS-1002, Motorcraft FL-910S, Bosch 3330, Royal Purple 10-2835, Mann ML 1003, Fram XG3614, Mahle OC 981 and Pennzoil HPZ-21.

Raise Front of Vehicle
Under Engine Skid Plate
Remove Shield Screws
The first steps are to warm up the engine for a few minutes, park the vehicle on a level surface and shut off the engine.

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

Engage the emergency / parking brake and chock the rear wheels to prevent the vehicle from moving.

Then pop open the hood, twist off the oil filler cap in the counter clockwise direction and pull up the yellow handled oil level dipstick an inch or two.

Removing the oil filler cap and pulling out the dipstick will help prevent a vacuum when forming and allow the old oil to drain out more quickly.

Raise the front passenger side of the car with the floor jack and securely support it with at least two jack stands.

Slide under the passenger side of the engine bay with a Torx T-30 star bit screwdriver, a 15mm socket, a ratcheting wrench and a used oil catch container.

Torx T30 Screws
Turn Counter Clockwise
Under Tray Removed
Remove the 8 Torx T-30 screws that hold the grey fabric and cardboard under engine skid plate cover in place by turning them counter clockwise.

Slide the under engine cover out of the way and set the eight screws aside in a safe place.

8 T-30 Screws Total
Bolt, Oil Pan & Filter
Old Canister Oil Filter
Once the skid plate is removed, you'll be able to see the silver aluminum oil pan.

The silver metal oil drain bolt is located at the rear of the oil pan. The canister style oil filter is mounted vertically just in front of the oil pan.

15mm Oil Drain Bolt
Position Used Oil Basin
Loosen 15mm Drain Bolt
Slide the used oil catch container to just below the oil drain bolt.

Loosen the oil drain bolt by turning it counter clockwise and remove it.

Be careful when you remove the oil drain bolt, the old oil may be hot enough to burn your skin depending on how long you ran the engine in the first step.


Drain Out Old Motor Oil
Tighten Bolt - Clockwise
Move Used Oil Container
Allow the old oil to drain out for at least a few minutes or until the flow slows to an occasional drip.

If the oil drain bolt is equipped with a washer, inspect it and replace it if necessary.

Clean the area around the oil drain hole and re-insert the oil drain bolt. Spin it in by hand a few turns in the clockwise direction to prevent it from becoming cross threaded.

Tighten the oil drain bolt with the 15mm socket and ratcheting wrench to just past hand tight or about 20 ft lbs of torque by turning it clockwise.

Spin Off Old Oil Filter
Dip Finger In New Oil
Lubricate Rubber Gasket
Move the used oil catch basin to just below the old oil filter.

Spin off the old oil filter in the counter clockwise direction. If you have trouble turning the filter, use a straps or jaws type oil filter wrench.

Allow the old oil to drain from the oil filter receptacle for a few minutes.

I always buy the Mobil1 M1-102 oil filter since it has excellent reviews on Amazon.

Dip your pinky finger in some new SAE 5W-20 oil and lubricate the rubber o-ring on the new oil filter. Lubricating the new oil filter's rubber gasket will help it form a better seal to prevent oil leaks and make it easier to remove at the next oil change.

Spin On New Oil Filter
Replace Skid Plate Screws
Under Engine Cover Installed
Clean off the oil filter receptacle and make sure that the rubber o-ring from the old oil filter is not still attached to the engine.

Spin on the new oil filter in the clockwise direction to about 1/4 to 1/3 turn past hand tight. Do not over tighten the oil filter and do not use the oil filter wrench to tighten it.

Over tightening the oil filter can damage the rubber gasket and cause an oil leak to develop.

Double check that both the oil drain bolt and the new oil filter are tight before moving on to the next steps.

Line up the under engine cover in place and insert the eight screws. Tighten the 8 screws until they are snug by turning them clockwise with the Torx T30 star bit screwdriver.

Lower Vehicle From Stands
Insert Automotive Funnel
Pour In New 5W-20 Oil
Lower the car from the jack stands and the floor jack.

Insert an automotive funnel in to the oil filler hole.

Pour in about 4 quarts of the Duratec 20 2.0L engine's 4.5 US quart (or 4.3L) total capacity for an oil change with filter replacement.

It is far better to have less than enough oil in an engine than too much.

Replace Oil Filler Cap
Check Dipstick Oil Level
Replace Oil Dipstick
Replace the oil filler cap by turning it clockwise.

Run the engine for a few minutes, turn it off, and allow the oil to drain down to the pan for about 5-10 minutes.

Pull out the yellow handled dipstick and check the engine oil level.

Slowly pour in more oil and repeatedly check the dipstick until the level reaches at or just below the upper hole in the metal.

Replace the dipstick.

To reset the oil life monitoring system, follow these steps:

1. Turn the ignition switch to the "On" position but don't start the engine. (For models with the push button start, press and hold the Start/Stop button for two seconds but do not press the brake pedal. Do not start the engine.)
2. Press both the gas and brake pedals at the same time and keep them pressed down.
3. After 3 seconds, you'll see the "Service: Oil reset in prog." message.
4. After another 25 seconds, you'll see the "Service: Oil Reset Complete" message on the display.
5. Let go of both the accelerator and brake pedals.
6. Turn the key to the "Off" position. (For vehicles with the push button start, press the button to turn off the vehicle.)

Be sure to record the oil change in your service records. It's also a good idea to check your driveway or garage during the next few days for drops of oil that may indicate a leak from the drain bolt or the filter.
