Owners of other General Motors vehicles such as the Chevrolet Impala, Monte Carlo, Malibu, Spark, Sonic, Cruze, Volt, SS, Camaro, Caprice, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado, Buick Verano, Regal, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra, Terrain, Acadia, Yukon, Savana, Cadillac CT6, ATS-V, ATS, ELR, CTS, XTS, XT5, SRX, Escalade and Holden Commodore may also find these DIY instructions to be helpful.

The tools and other items needed to complete this procedure include a floor jack, two jack stands (or automotive ramps), a 15mm socket with a 3/8" drive ratcheting wrench, a used oil catch basin, an automotive funnel and 6 U.S. quarts (5.7L) of new SAE 5W-30 oil.

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.

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

The silver metal oil drain bolt is located on the rear passenger corner of the silver metal oil pan. The bolt head faces back towards the rear of the car.

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

Be careful when you remove the oil 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 oil drain bolt by turning it counterclockwise with the 15mm socket and the 3/8" drive ratcheting wrench.

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

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

Tighten the drain bolt in the clockwise direction to just past hand tight or about 20 ft-lbs of torque.

Slide the used oil catch basin forward to just below the oil filter, which is situated horizontally and located on the front of the engine.

Twist off the old oil filter in the counterclockwise direction.

If you have trouble loosening the old oil filter, use a strap oil filter wrench.

I normally use and recommend the excellent Lisle 63600 oil filter wrench, but it didn't fit well since the oil filter is so close to the radiator fan housing.

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

I recommend buying the Mobil 1 M1-212 oil filter since it has excellent reviews on Amazon.

Dip your pinky finger in to some new oil and lubricate the rubber o-ring on the new oil filter.

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

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

Carefully lower the car from the jack stands by using the floor jack.

The LFX 3.6L V6 engine's total capacity for an oil change with filter replacement is 6.0 U.S. quarts (or 5.7L) of SAE 5W-30 oil.

It is far better to have slightly less oil than necessary in an engine than to run an engine that has been over filled.

Running an engine that has been over filled may lead to sluggish performance or damage to gaskets and gaskets.

Slowly pour in only about 5 to 5.5 U.S. quarts of the new oil in to the funnel.

Temporarily replace the oil filler cap by twisting it on in the clockwise direction and push down the dipstick.

Pull out the dipstick, wipe it clean, re-insert it 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 just at or below the upper hole in the dipstick which indicates the "Full" or "Maximum" line.

You may not need to pour in the entire 6 U.S. quarts (or 5.7 liters) new oil for the level to reach the "Full" line.

Replace the dipstick and double check that the oil filler cap is tight.

Be sure to record the oil change in your car's service records.
