Capacity by engine option

Note: Always verify final fill on the dipstick after running the engine and letting it sit for a couple of minutes. Top off as needed to bring the level to the upper hashmark.

Oil change interval

• Normal service: Follow the GM Oil Life Monitor (OLM). In typical mixed driving with quality dexos1 oil, expect about 7,500–10,000 miles or up to 12 months between changes.
• Severe service (frequent short trips, extreme heat/cold, dusty roads, lots of idling/towing): Change every 5,000 miles or 6 months, whichever comes first, even if the OLM has not reached 0%.

Always reset the OLM after each oil change via the Driver Information Center.

Drain plug torque

• Drain plug torque: 18 lb-ft (25 N·m)
• Crush washer/seal: Replace the drain plug seal if equipped with a separate aluminum or fiber washer. Some OE plugs have an integral captive seal; inspect and replace the plug if the seal is damaged. If you need the exact washer or plug part number, consult your Chevrolet dealer with your VIN.

How to change the oil

1. Warm the engine, then raise and support the vehicle safely.
2. Remove the lower splash shield fasteners as needed to access the drain plug and filter.
3. Place a drain pan, remove the drain plug, and let oil drain completely.
4. Replace the crush washer (if used) and torque the drain plug to 18 lb-ft (25 N·m).
5. Spin off the PF64 filter. Lightly oil the new filter’s gasket and install hand-tight, then snug 3/4 turn (or torque per filter maker if specified).
6. Fill the crankcase with the listed initial capacity (1.5L: ~4.0 qt; 2.0L: ~5.0 qt) of 5W-30 dexos1 oil.
7. Start the engine, check for leaks, shut down, wait 2–3 minutes, and verify the oil level. Top off to the full mark as needed.
8. Reinstall the splash shield, reset the OLM, and properly recycle the used oil and filter.

Common issues / tips for this generation

• Use dexos1 Gen 2 (or newer) to reduce LSPI risk in these direct-injected turbo engines. Many premium 5W-30 oils now carry dexos1 Gen 3; those are backward-compatible and a fine upgrade.
• Don’t use 0W-20 in the Malibu unless specifically labeled for your engine and market. The 2021 Malibu 1.5L and 2.0L are specified for 5W-30 in North America.
• The PF64 filter has a specific bypass valve spec for GM turbo engines—avoid off-brand filters that don’t list PF64 compatibility.
• Inspect the undertray clips/bolts; broken retainers can lead to splash shield drag or loss. Keep extras on hand.
• If you notice oil seepage around the cam/valve cover or front cover, address promptly; minor leaks can worsen with turbo heat.
• Short-trip driving can cause fuel dilution in turbo DI engines. If you smell fuel in the oil or the level rises, shorten intervals and ensure the engine gets fully up to temp regularly.
