This automotive maintenance tutorial was specifically written to assist owners of the tenth generation (2014, 2015, 2016, 2017 and 2018) GM Chevy Impala in changing the motor oil and replacing the oil filter on the Ecotec LKW 2.5 liter DOHC inline four cylinder engine.

Owners of other General Motors vehicles such as the Malibu, Cruze, Camaro, Sonic, Spark, Volt, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, SS Sedan, Bolt, Colorado, Silverado, Buick Verano, Regal, LaCrosse, Cascada, Encore, Envision, Enclave, Canyon, Sierra 1500, Terrain, Acadia, Yukon, Savana, ATS, CTS, XTS, CT6, XT5, SRX and Escalade may also find these DIY instructions to be helpful.

A few compatible replacement oil filters with their part numbers include the following: Mobil 1 M1-113, ACDelco PF48E, Royal Purple 10-48, Fram PH10060, Bosch 3334, Purolator PL12222, Pennzoil HPZ-167 and Champion COS10060.

The tools and other items required to complete this procedure include a floor jack, two jack stands, a 15mm socket, a 3/8" drive ratchet, a used oil catch container, an automotive funnel and 5 U.S. quarts (4.7L) of new SAE 5W-20 oil.

Oil Pan & Oil Filter
The first three steps are to warm up the engine for a few minutes, park the car on a level surface and turn off the ignition.

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

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

Open the hood, twist off the oil filler cap in the counterclockwise direction and pull out the dipstick handle an inch or two.

Removing the oil filler cap and lifting up the dipstick will help prevent a vacuum from forming and allow the old oil to drain out quickly.

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

I prefer to keep three tires on the ground for extra safety.

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

Used Oil Catch Basin
The silver metal oil drain bolt is located at the rear edge of the black metal oil pan.

The canister style oil filter is located just in front of the oil pan.

Slide the used oil catch container to just below the drain bolt.

Drain Out Old Oil

Tighten 15mm Clockwise
Loosen the oil drain bolt by turning it counterclockwise with the 15mm socket and a 3/8" drive ratcheting wrench.

Be careful when you remove the oil drain bolt. The old oil might still be hot enough to burn your fingers.

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

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

Spin in the oil drain bolt a few turns by hand in the clockwise direction to prevent it from becoming cross threaded.

Tighten the oil drain bolt with the 15mm socket and a 3/8" drive ratchet to just past hand tight or about 20 lb-ft of torque.

Twist Off Old Oil Filter

Slide the used oil catch basin to just below the old oil filter.

To loosen the old oil filter, rotate it counterclockwise.

I recommend using an oil filter wrench such as the Lisle 63600 since it makes it much easier to remove a tight filter.

Allow the old oil to drain out from the filter receptacle for at least a minute or two.

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

Dip Finger In New Oil

Lubricate Rubber O-Ring

Tighten Filter Clockwise
Dip your pinky finger in to some new SAE 5W-20 oil and lubricate the rubber o-ring gasket on the new oil filter.

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

Spin on the new oil filter in the clockwise direction and tighten it to about 1/3 to 1/2 turn past hand tight.

Try to avoid over tightening the new filter to prevent from damaging the o-ring gasket which may lead to an oil leak.

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

Lower Car From Stands

Insert Automotive Funnel

Pour In New 5W-20 Oil
Carefully lower the car from the jack stands by using the floor jack.

Insert the automotive funnel in to the oil filler hole.

The Ecotec LKW 2.5L I4 engine's total capacity specification for an oil change with a filter replacement is 5.0 U.S. quarts (or 4.7 liters).

I recommend only pouring in about 4 1/2 quarts at first.

It is much better to have slightly less oil than necessary in an engine than to over fill it. Running an engine that has been overfilled with oil can lead to sluggish performance and possibly cause damage to seals, gaskets or other components.

You may not need to pour in the entire 5 quarts depending on how long you allowed the old oil to drain out.

Push Down Dipstick
2014-2018-Chevrolet-Impala-Engine-Oil-Change-Guide-024
Check Oil Level
Temporarily replace the oil filler cap and push down the oil dipstick.

Start the engine and allow it idle for a few minutes. Then turn off the engine and wait at least 5 to 10 minutes for the new oil to drain down to the oil pan.

Pull out the dipstick, wipe it clean, fully re-insert it and then 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 just at or below the top of the cross hatched area which indicates the "Full" or "Maximum" line.

There are two methods for resetting the Engine Oil Life System.

If your Impala is equipped with the "DIC" (driver information center) display, follow these steps: 1. Use the controls to display "Remaining Oil Life" on the DIC. 2. Press the check mark icon and hold it down for a few seconds until the "Change Engine Oil Soon" message goes away and the oil life resets to 100%.

For Impala models with out the DIC, follow these steps: 1. Turn the ignition switch to the "On" position but do not start the engine. 2. Fully press down the accelerator (gas) pedal three times within five seconds. 3. The "Change Engine Oil Soon" message should disappear. If not, repeat the steps.

Be sure to record the oil change in your car's service records. It's also a good idea to check your driveway, garage or parking spot for drops of fresh oil which may indicate a leak from the drain bolt or the new filter.
