Follow these steps carefully
Idle the ATS-V for 2–3 minutes so the 3.6L twin-turbo's oil drains quickly, then shut it off. Because the car sits low and needs to stay level for an accurate fill, drive it onto ramps or lift all four corners evenly. Set the parking brake and chock the wheels.
The ATS-V has a large belly pan covering the oil pan — remove its Torx or 7mm screws and lower it carefully. Keep track of the fasteners; they are easy to lose. With the shield off, the oil drain plug and filter housing are accessible.
Remove the oil fill cap on the cam cover to vent the crankcase. Position a large drain pan under the plug, loosen it with a wrench, and remove it by hand. The LF4 holds 6 quarts, so allow a full 10–15 minutes for the turbo oil lines to drain back completely.
Unscrew the plastic cartridge filter housing cap — on the 3.6L it is accessed from above or below depending on model year, so locate it before draining. Pull the old cartridge element out, discard it, and wipe the housing clean. Lubricate the new O-ring with fresh oil, seat the new cartridge, and thread the cap back on snugly by hand.
Thread the drain plug in by hand and snug it with a wrench — the pan threads are delicate. Pour in 6 quarts of 5W-30 dexos-approved full synthetic through the fill tube. Reinstall the fill cap.
Start the engine and let it idle for a minute while you watch the drain plug and filter housing for drips. Shut it off, wait 2 minutes, then check the dipstick — the twin-turbo engine must read at the full mark, not over. Top up in small increments if needed.
Refit the belly pan and tighten all its screws so it does not flap at speed. Reset the oil-life monitor via the steering-wheel controls in the driver information center. Lower the car and take a short drive, then recheck the level once more after the oil has circulated.
Pour the used synthetic oil into sealed containers and bag the old filter element. Most auto-parts stores accept both for free recycling. Log the mileage — the turbocharged LF4 is hardest on oil, so do not stretch intervals beyond the monitor's recommendation.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
